The present invention concerns apparatuses and associated methods useful for delivering stimulation to the vestibular system and/or the nervous system of an individual, thereby inducing physiological changes in the individual and/or treating a disorder or symptom of the individual.
Caloric vestibular stimulation (CVS) has been widely and safely utilized for more than a century for diagnostic purposes, particularly in the emergency room to detect brain function after injury and in ear, nose and throat practice to assess balance.
CVS activates the sensory organs of the vestibular system located within the inner ear. The core elements consist of the semi-circular canals, which sense rotational motion, and the otoliths, which sense linear acceleration. Motion within the semi-circular canals is detected through motion of internal fluid (endolymph), which in turn activates hair cells that generate electrical signals, which are then transmitted via the 8th cranial nerve to the brainstem and widely throughout the cerebellum and cortical regions. In traditional CVS, irrigation of the external auditory canal (the ear canal) with warm or cold water/air changes the density of the endolymph in the semi-circular canal of the inner ear, which in turn activates the pathways noted above. Nystagmus, or the vestibulo-ocular reflex, is an easily observed result of CVS, wherein the eyes move spontaneously, even if the patient is unconscious.
There have been intriguing (but largely anecdotal) reports of using CVS as a therapeutic measure. Survey articles document a variety of outcomes and discuss some of the mechanisms involved (Miller et al., A
In addition, vestibular stimulation is also known to release important neurotransmitters (e.g., serotonin, acetylcholine, histamine, endorphins, vasopressin and dopamine) (Fu-rong et al., C
In contrast to both pharmaceutical treatment and neurostimulation devices which employ electrical signals, CVS appears to have an advantage: although nystagmus habituates with repetition of CVS (Naito et al., B

For example, the computer-usable or computer-readable medium may be an electronic, optical, electromagnetic, infrared or semiconductor system, apparatus or device.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and relevant art and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein. Well-known functions or constructions may not be described in detail for brevity and/or clarity.
As used herein, the terms “actively controlled waveform” and “actively controlled, time-varying thermal waveform” refer to a thermal waveform in which the intensity and/or the directionality of the activation signal used to deliver the thermal waveform and/or the temperature of the earpiece used to deliver the thermal waveform is repeatedly adjusted (e.g., continuously adjusted or substantially continuously adjusted) during delivery of the thermal waveform. For example, the activation signal driving the TED(s) used to deliver the thermal waveform may be continuously adjusted in response to feedback data from one or more sensors (e.g., a temperature sensor configured to sense the temperature of the earpiece with which the TED(s) is/are associated). Such active control may be used to minimize errors in the delivery of a prescribed thermal waveform (e.g., by minimizing thermal drift, which may otherwise allow the patient's body temperature to adversely affect the accuracy).
As used herein, the term “adjuvant treatment” refers to a treatment session in which the delivery of one or more thermal waveforms to the vestibular system and/or the nervous system of a patient modifies the effect(s) of one or more active agents and/or therapies. For example, the delivery of one or more thermal waveforms to the vestibular system and/or the nervous system of a patient may enhance the effectiveness of a pharmaceutical agent (by restoring the therapeutic efficacy of a drug to which the patient had previously become habituated, for example). Likewise, the delivery of one or more thermal waveforms to the vestibular system and/or the nervous system of a patient may enhance the effectiveness of counseling or psychotherapy. In some embodiments, delivery of one or more thermal waveforms to the vestibular system and/or the nervous system of a patient may reduce or eliminate the need for one or more active agents and/or therapies. Adjuvant treatments may be effectuated by delivering one or more thermal waveforms to the vestibular system and/or the nervous system of a patient prior to, currently with and/or after administration of one or more active agents and/or therapies.
As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
As used herein, the terms “chronic treatment,” “chronically treating” and the like refer to a therapeutic treatment carried out at least once per week (e.g., two or three times per week, daily, etc.) over an extended period of time. Chronic treatment typically lasts at least one to two weeks (and, in some embodiments, at least one to two months), but may last as long as required to achieve and/or maintain therapeutic efficacy for the particular condition or disorder for which the treatment is carried out (i.e., the device may be used periodically throughout the patient's life).
As used herein, the term “controller feedback data” refers to data that is transmitted to the controller by one or more TEDs and/or one or more sensors and is used by the controller to verify the accuracy of the thermal waveform(s) being delivered, to modulate the activation of one or more TEDs so as to deliver the appropriate thermal waveform(s) and/or to enable the controller to activate safety precautions in the event of a system failure. For example, controller feedback data may comprise data associated with the temperature of an earpiece, wherein said data is used to verify that the appropriate temperature is being delivered to the ear canal of a patient, to enable the controller to increase/decrease the activation of one or more TEDs to ensure that the appropriate temperature is delivered to the ear canal of a patient and/or to trigger a system shutdown if the temperature of the earpiece drops below a low temperature threshold (e.g., about 10 degrees Centigrade) or exceeds a high temperature threshold (e.g., about 50 degrees Centigrade). Likewise, controller feedback data may comprise data associated with the temperature of a heat sink that is thermally coupled to one or more TEDs, wherein said data is used to trigger a system shutdown if the temperature of the heat sink exceeds a high temperature threshold (e.g., about 50 degrees Centigrade).

In some embodiments, data associated with the delivery of one or more thermal waveforms comprises controller feedback data, patient feedback data and/or physician feedback data. In some embodiments, data associated with the delivery of one or more thermal waveforms comprises, consists essentially of or consists of data associated with the precise time/temperature parameters of the thermal waveform(s) delivered to the patient and a subjective measure of efficacy (e.g., a patient-reported pain score).
As used herein, the term “data associated with the fit of the earpiece(s)” may include, but is not limited to, data associated with the impedance between an earpiece inserted into the ear canal of a patient and an electrode affixed to a second location on/in said patient's body (e.g., an electrode placed in or adjacent to the patient's other ear canal), data associated with the rate at which the ear canal and/or the inner ear cooled in response to a cooling stimulus (e.g., data from a temperature sensor, such as thermistor, that monitors how quickly the ear canal and/or the inner ear cools in response to a cooling waveform), data associated with the rate at which the ear canal and/or the inner ear warmed in response to a warming stimulus (e.g., data from a temperature sensor, such as a thermistor, that monitors how quickly the ear canal and/or the inner ear warms in response to a warming waveform) and patient comments regarding the subjective fit of the earpiece(s). In some embodiments, data associated with the fit of the earpiece(s) comprises, consists essentially or consists of data associated with the impedance between an earpiece inserted into the right ear canal of a patient and an earpiece inserted into the left ear canal of said patient.

For example, a thermal waveform may be indicated for use in the treatment of migraines if it has effectively treated migraines in the past or if it belongs to a class of thermal waveforms that are known to treat migraines. Likewise, a thermal waveform may be approved for use in the treatment of a given disorder if it has received regulatory approval (e.g. FDA approval) for such use, or if it belongs to a class of thermal waveforms that have been approved for the treatment of that disorder. An idealized thermal waveform may be indicated/approved for use in the treatment of multiple diseases/disorders/injuries.
As used herein, the term “patient” refers to both human subjects and animal subjects, including, but not limited to, mice, rats, rabbits, cats, dogs, pigs, horses, monkeys, apes, etc. The patient may be male or female. That patient may be of any suitable age, including infant, juvenile, adolescent, adult and geriatric ages. In some embodiments, the methods, devices and systems of the present invention may be used to induce physiological and/or psychological responses in a patient for medically diagnostic and/or therapeutic purposes. For example, the methods, devices and systems of the present invention may be used to diagnose and/or treat mammalian subjects, such as mice, rats, pigs and monkeys, for medical research or veterinary purposes.
As used herein, the term “patient information” refers to data associated with one or more patients. Patient information may comprise, but is not limited to, information related, to a patient's identity, a patient's cognitive abilities, a patient's medical history, a patient's current symptoms (if any), a patient's present diagnosis (if any), a patient's current prescriptions (if any) and data associated with the delivery of one or more thermal waveforms to the vestibular system and/or the nervous system of a patient.

As used herein, the terms “prescription” and “prescription protocol” refer to a set of instructions and/or limitations associated with stimulation of the vestibular system and/or the nervous system of a patient. In some embodiments, a prescription comprises, consists essentially of or consists of a set of instructions for delivering of one or more thermal waveforms (e.g., one or more actively controlled, time-varying thermal waveforms) to the vestibular system and/or the nervous system of a patient (e.g., by warming and/or cooling an earpiece positioned in the ear canal of the patient). A prescription may comprise a set of instructions for delivering one or more thermal waveforms to the left vestibular system of a patient (by delivering one or more thermal waveforms to the left ear canal of the patient) and/or a set of instructions for delivering one or more thermal waveforms to the right vestibular system of a patient (by delivering one or more thermal waveforms to the left ear canal of the patient) (i.e., one prescription may comprise instructions for stimulating both the right and left vestibular systems). A prescription may comprise any suitable instructions and/or limitations, including, but not limited to, the parameters of the waveform(s) to be delivered to the patient, the number and frequency of treatment sessions (e.g., X treatment sessions over Y time period), a limitation as to how many treatment sessions may be administered during a given time period (e.g., no more than X treatment sessions within Y time period), instructions as to which thermal waveform(s) will be administered during a given treatment session (and in what order they are to be administered), instructions as to which vestibular system will receive a given waveform (e.g., right, left or both) and an expiration date. In some embodiments, a prescription comprises instructions for delivering a placebo (i.e., for fooling a patient into believing one or more thermal waveforms has been delivered even though no such deliver has occurred). In some embodiments, the prescription is generated by a physician. Any conventional security means may be provided to prevent unauthorized modification of the prescription (e.g., the prescription may be password protected, with only the prescribing physician having knowledge of and/or access to the password).
As used herein, the terms “treatment,” “treat,” and “treating” refer to reversing, alleviating, reducing the severity of, delaying the onset of, inhibiting the progress of or preventing a disease or disorder as described herein, or at least one symptom of a disease or disorder as described herein (e.g., treating one or more of tremors, bradykinesia, rigidity or postural instability associated with Parkinson's disease; treating one or more of intrusive symptoms (e.g., dissociative states, flashbacks, intrusive emotions, intrusive memories, nightmares, and night terrors), avoidant symptoms (e.g., avoiding emotions, avoiding relationships, avoiding responsibility for others, avoiding situations reminiscent of the traumatic event) or hyperarousal symptoms (e.g., exaggerated startle reaction, explosive outbursts, extreme vigilance, irritability, panic symptoms, sleep disturbance) associated with post-traumatic stress disorder).

For example, a patient with both depression and anxiety (e.g., PTSD) can be treated for both disorders, concurrently, with the methods and systems of the present invention.
As used herein, the term “vestibular system” has the meaning ascribed to it in the medical arts and includes, but is not limited to, those portions of the inner ear known as the vestibular apparatus and the vestibulocochlear nerve. The vestibular system, therefore, further includes, but is not limited to, those parts of the brain that process signals from the vestibulocochlear nerve.
As used herein, the terms “waveform,” “waveform stimulus” and “thermal waveform” refer to a thermal stimulus (heating and/or cooling) delivered to the ear canal of a patient. “Waveform” is not to be confused with “frequency,” the latter term concerning the rate of delivery of a particular waveform. The term “waveform” is used herein to refer to one complete cycle thereof, unless additional cycles (of the same, or different, waveform) are indicated. As discussed further below, time-varying thermal waveforms are preferred over square waveforms in carrying out the present invention.
In general, a waveform of the present invention comprises a leading edge, a peak, and a trailing edge.
The waveform leading edge is preferably ramped or time-varying: that is, the amplitude of the waveform increases through a plurality of different temperature points over time (e.g., at least 5, 10, or 15 or more distinct temperature points, and in some embodiments at least 50, 100, or 150 or more distinct temperature points, from start to peak). The shape of the leading edge may be a linear ramp, a curved ramp (e.g., convex or concave; logarithmic or exponential), or a combination thereof. A vertical cut may be included in the waveform leading edge, so long as the remaining portion of the leading edge progresses through a plurality of different temperature points over time as noted above.
The peak of the waveform represents the amplitude of the waveform as compared to the patient's body temperature. In general, an amplitude of at least 5 or 7 degrees Centigrade is preferred for both heating and cooling waveform stimulation. In general, an amplitude of up to 25 degrees Centigrade is preferred for cooling waveform stimulation (e.g., 15 degrees Centigrade). In general, an amplitude of up to 8 or 10 degrees Centigrade is preferred for heating waveform stimulus (e.g., 6 degrees Centigrade). The peak of the waveform may be truncated (that is, the waveform may reach an extended temperature plateau), as long as the desired characteristics of the leading edge, and preferably trailing edge, are retained. For heating waveforms, truncated peaks of long duration (that is, maximum heat for a long duration) are less preferred, particularly at higher heats, because of the potential that the patient may experience a burning sensation.
The waveform trailing edge is preferably ramped or time-varying: that is, the amplitude of the waveform decreases through a plurality of different temperature points over time (e.g., at least 5, 10, or 15 or more distinct temperature points, or in some embodiments at least 50, 100, or 150 or more distinct temperature points, from peak to trough). The shape of the trailing edge may be a linear ramp, a curved ramp (e.g., convex or concave; logarithmic or exponential), or a combination thereof. A vertical cut may again be included in the waveform trailing edge, as long as the remaining portion of the trailing edge progresses through a plurality of different temperature points over time as noted above.
The duration of a waveform (or the frequency of that waveform stimulus) is the time from the onset of the leading edge to either the conclusion of the trailing edge or (in the case of a vertically cut waveform) the onset of a subsequent waveform. In general, each waveform has a duration, or frequency, of from one or two minutes up to ten or twenty minutes.
If a first waveform is followed by a second waveform, the minimal stimulus point therebetween (i.e., the point of minimal heating or minimal cooling) is referred to as a trough. Like a peak, the trough may be truncated, as long as the desired characteristics of the trailing edge and the following leading edge are retained. While the trough may represent a return to the patient's current body temperature, in some embodiments minor thermal stimulation (e.g., cooling or heating by 1 or 2 degrees up to 4 or 5 degrees Centigrade) may continue to be applied at the trough (or through a truncated trough).
In a treatment session, a plurality of waveforms may be delivered in sequence. In general, a treatment session will comprise 1, 2 or 3 waveforms, up to about 10 or 20 or more waveforms delivered sequentially. Each individual waveform may be the same, or different, from the other waveform(s).
The first waveform of a treatment session is initiated at a start point, which start point may be at or about the patient's body temperature at the time the treatment session is initiated (typically a range of about 34 to 38 degrees Centigrade, around a normal body temperature of about 37 degrees Centigrade. The lower point, 34, is due to the coolness of the ear canal in comparison with the rest of the body. It typically will not be above about 37 unless the patient is febrile). Note that, while the patient's ear canal may be slightly less than body temperature (e.g., about 34 to 36 degrees Centigrade), the starting temperature for the waveform is typically body temperature (the temperature of the inner ear), or about 37 degrees Centigrade. In some embodiments, however, the temperature of the treatment device may not have equilibrated with the ear canal prior to the start of the treatment session, and in such case the start point for at least the first waveform may be at a value closer to room temperature (normally bout 23 to 26 degrees Centigrade).
A treatment session may have a total duration of five or ten minutes, up to 20 or 40 minutes or more, depending on factors such as the specific waveform or waveforms delivered, the patient, the condition being treated, the benefit being sought, etc. In some embodiments, a treatment session may comprise one or more breaks (i.e., periods wherein no CVS is given). For example, a treatment session may comprise multiple stimulation periods with a break between each stimulation period and may have a total duration of 60 minutes or more.
Treatment sessions are preferably once a day, though in some embodiments more frequent treatment sessions (e.g., two or three times a day or more) may be employed. Day-to-day treatments may be by any suitable schedule: every day, every other day, twice a week, as needed by the patient, etc. The overall pattern of treatment is thus typically chronic (in contrast to “acute,” as used in one-time experimental studies).

As shown in
I. Controller
Any suitable controller can be used to carry out the present invention, including, but not limited to, those described in U.S. Patent Publication Nos. 2010/0198204 and 2010/0198282; in U.S. patent application Ser. Nos. 12/970,312 and 12/970,347 and in U.S. Provisional Application Nos. 61/497,761, the disclosure of each of which is incorporated herein by reference in its entirety.
The controller may be configured to activate at least one TED. In some embodiments, the controller is configured to activate at least one TED to deliver one or more thermal waveforms to the vestibular system and/or the nervous system of a patient (e.g., by heating and/or cooling the earpiece(s) that is/are thermally coupled to the TED. For example, the controller may be configured to activate the TED(s) based upon a prescription comprising a set of instructions for delivering one or more thermal waveforms to the vestibular system and/or the nervous system of a patient (i.e., the controller may be configured to activate the TED(s) so as to deliver the prescribed thermal waveform(s) to the vestibular system and/or the nervous system of the patient).
The controller may be configured to selectively and separately activate a plurality of TEDs. For example, the controller may be configured to selectively and separately activate the TED(s) thermally coupled to an earpiece inserted into the left ear canal of a patient and the TED(s) thermally coupled to an earpiece inserted into the right ear canal of a patient (e.g., to deliver a thermal waveform only to the left ear canal of the patient, to deliver a thermal waveform only to right ear canal of the patient or to simultaneously deliver different thermal waveforms to the left and right ear canals of the patient). Likewise, the controller may be configured to separately activate a plurality of TEDs thermally coupled to a single earpiece.
The controller may be configured to activate the TED(s) in any suitable manner, including, but not limited to, activation with direct current and/or electrical pulses. In some embodiments, the controller is configured to activate the TED(s) in a continuous or substantially continuous manner, adjusting one or more parameters of TED activation (e.g., magnitude, duration, pulse width, etc.) to deliver the desired thermal stimulus. For example, the controller may be configured such that it continuously or substantially continuously activates each of the TEDs with which it is operatively connected and delivers different thermal stimuli by modulating the type and/or level of activation applied to each TED.
The controller may be configured to activate the TED(s) to deliver any suitable thermal waveform or combination of thermal waveforms, including, but not limited to, those described in U.S. Provisional Patent Application Nos. 61/424,132, 61/498,096, 61/424,326, 61/498,080, 61/498,911 and 61/498,943, the disclosure of each of which is incorporated herein by reference in its entirety.

The controller may also be configured to activate the TED(s) to deliver a constant thermal stimulus to the ear canal(s) of a patient. For example, the controller may be configured to activate the TED(s) so as to maintain the temperature of a patient's ear canal at a target temperature (e.g., to hold a patient's right canal at 20 degrees Centigrade while a thermal waveform is delivered to the patient's left canal).
The controller may likewise be configured to deliver one or more placebo waveforms (i.e., to fool a patient into believing one or more thermal waveforms has been delivered even though no such delivery has occurred).
In some embodiments, the controller is operatively connected to at least one TED via a thermal stimulation conductive line. In those embodiments wherein the controller is operatively connected to a plurality of TEDs, the controller may be operatively connected to each TED via a separate thermal stimulation conductive line. In some such embodiments, each of the plurality of separate thermal stimulation conductive lines is bundled together into one or more thermal stimulation leads (e.g., the thermal stimulation conductive lines connected to the TED(s) thermally coupled to the right earpiece may be bundled separately from the thermal stimulation conductive lines connected to the TED(s) thermally coupled to the left earpiece). In some such embodiments, each thermal stimulation lead is connected to the controller via a lead interface (e.g., one or more thermal stimulation leads may be connected to the controller using an 18-pin connector).
In some embodiments, the controller is operatively connected to at least one TED via a wireless connection (using a radiofrequency transceiver or a Bluetooth connection, for example).

The controller may be configured to receive and/or transmit data from/to various devices, including, but not limited to, a patient control device, a physician control device, a physician support device, a registry, a TED, a sensor and/or a portable memory device (e.g., an SD memory card).

In some embodiments, one of the aforementioned modules is split into two or more distinct modules (e.g., the controller may comprise a waveform generation module that enables a user to generate the parameters, indications and/or approvals of one or more thermal waveforms and a waveform update module that enables a user to modify the parameters, indications and/or approvals of one or more thermal waveforms).

In some preferred embodiments, an LED indicator light may be illuminated throughout a treatment session and deactivated upon completion of the treatment session, and may change color to signal various events within a treatment session (e.g., the light may appear blue during cooling periods and appear red during heating periods).
J. Impedance Module
In some embodiments, the controller comprises an impedance module configured to detect and/or monitor the impedance and/or capacitance between an earpiece inserted into the ear canal of a patient and an electrode affixed to a second location on/in said patient's body. For example, the impedance module may be configured to deliver an electrical current to the earpiece and to measure and/or record the impedance and/or capacitance between the earpiece and the electrode.
In some embodiments, the impedance module may be configured to detect and/or monitor the impedance and/or capacitance between an earpiece inserted into the right ear canal of a patient and an earpiece inserted into the left ear canal of said patient. For example, the impedance module may be configured to deliver an electrical current to the earpiece inserted into the right ear canal of the patient and to measure and/or record the impedance and/or capacitance between the two earpieces.
Without wishing to be bound by theory, it is believed that if each of the earpieces is in substantially good thermal contact with the patient's ear canal, then the earpieces will also be in substantially good electrical contact with the patient's ear canals, and the patient's head will substantially complete an electrical circuit between the earpieces. However, if either of the earpieces is not in substantially good thermal contact with the patient's ear canal, then there will generally be poor electrical contact with the patient's ear canal, and the patient's head will not complete the electrical circuit between the earpieces and an open circuit will be detected by the impedance module.
The impedance value between an earpiece inserted into the ear canal of the patient and the electrode affixed to a second location (e.g., an earpiece inserted into the patient's other ear canal) may be used to estimate the thermal contact between the earpiece(s) and the patient's ear canal(s). In some embodiments, impedance values may be detected for a range of patients to determine a range of impedance values in which it may be assumed that the earpiece(s) is/are in substantially good thermal contact with the patient's ear canal(s). When a vestibular stimulation device is being fitted to a new patient, the impedance value may be detected, and if the impedance value is within the acceptable range, it may be assumed that there is substantially good thermal contact between the earpiece(s) and the patient's ear canal(s). In some embodiments, when a vestibular stimulation device is being fitted to a new patient, the impedance value between the earpiece inserted into the right ear canal of the patient and the earpiece inserted into the left canal of the patient may be detected and used as a patient-specific baseline to later determine whether the patient is using the vestibular stimulation device in the proper configuration (i.e., whether the earpieces are properly fitted into the patient's ear canals during a given treatment session).
The impedance module may be configured to monitor the impedance value between an earpiece inserted into the ear canal of a patient and an electrode affixed to a second location on/in said patient's body (e.g., between two earpieces), and the impedance values may be analyzed (e.g., by a medical health professional or the impedance module) to determine whether the earpiece(s) is/was properly fitted at various times before, during and/or after delivery of the thermal waveform(s). In some embodiments, the impedance module may be configured to provide feedback to the user if/when the impedance value indicates that the earpiece(s) are not in substantially good thermal contact with the patient's ear canal(s). In this configuration, the impedance module may provide an estimation of a degree of thermal contact between the earpiece(s) and the patient's ear canal(s) in real-time or in data recorded and analyzed at a later time.
The impedance module may be configured to provide controller feedback data to the control module so that the control module may modulate the amplitude of the waveform(s) delivered by the TED(s) responsive to the degree of thermal contact between the earpiece(s) and the patient's ear canal(s). For example, if the impedance module determines that there is a poor fit and poor thermal contact between the earpiece(s) and the ear canal(s), then the control module may increase the thermal output of the TED(s) to compensate for the poor thermal contact.
K. Security Module
In some embodiments, the controller comprises a security module configured to prevent unauthorized use of the controller (i.e., to prevent unauthorized persons from using the vestibular stimulation device, to prevent authorized persons from using the vestibular stimulation device in an unauthorized manner, etc.).
The security module may be configured to prevent unauthorized use of the controller using any suitable means of security, including, but not limited to, password protection and data encryption. For example, the security module may be configured such that a user is required to input a designated password prior to initializing treatment; generating and/or modifying a thermal waveform, generating, modifying, updating and/or extending a prescription; entering/viewing patient feedback data; entering/viewing physician feedback data and/or entering/viewing patient information (

In some embodiments, the safety module is configured to deactivate the controller if/when the temperature of an earpiece surpasses a specified safety threshold. For example, the safety module may be configured to deactivate the controller if/when the temperature of the earpiece drops below about 10 degrees Centigrade and/or rises above about 50 degrees Centigrade.
In some embodiments, the safety module is configured to deactivate the controller if/when the temperature of a heat sink that is thermally coupled to an earpiece surpasses a specified safety threshold. For example, the safety module may be configured to deactivate the controller if/when the temperature of the heat sink drops below about 5 degrees Centigrade and/or rises above about 50 degrees Centigrade.
In some embodiments, the safety module is configured to deactivate the controller if/when one or more of the activation signals sent from the controller to the associated TED(s) indicates that the system is may be operating outside of a predefined safety range. For example, the safety module may be configured to deactivate the controller if/when an activation signal sent from the controller to an associated TED exceeds the level of activation that would normally be required to deliver the prescribed thermal waveform in a properly functioning system.

Earpieces of the present invention may comprise any suitable material, including, but not limited to, a rigid, thermally conductive material (e.g., a metal or a metal alloy). For example, the earpiece(s) may comprise aluminum or an aluminum alloy (e.g., 6061 aluminum).
Earpieces of the present invention may be of any suitable size/shape. In some embodiments, the earpiece(s) comprise(s) a distal end configured so as to be insertable into the left ear canal and/or the right ear canal of a patient and a proximal end configured so as to be thermally connected to one or more TEDs. In some embodiments, each earpiece weighs between about 1 and about 10 grams (e.g., about 9 grams or less or about 4 grams or less).
Earpieces of the present invention may possess any suitable heat transfer properties. In some embodiments, the earpiece(s) is/are more efficiently heated than cooled. For example, the earpiece(s) may have a slew rate of about 15 degrees Centigrade per minute or greater during delivery of a cooling stimulus and a slew rate of about 20 degrees Centigrade per minute or greater during delivery of a warming stimulus.
Earpieces of the present invention may comprise a thermally conductive covering. For example, a thermally conductive cushion may cover one or more portions of the earpiece(s) (e.g., the portion of an earpiece that is inserted into the ear canal of a patient during use may be covered in a thermally conductive cushioning material to increase thermal contact between the earpiece and the ear canal (i.e., by conforming to the shape of the ear canal)). The thermally conductive covering may comprise any suitable material, including, but not limited to, coating materials that must be reapplied to the earpiece(s) before each use (e.g., water, water-based lubricants, thermal grease, gels and the like) and reusable coating materials (e.g., a thermally conductive plastic sheath or sleeve).
Earpieces of the present invention may comprise a thermally insulating covering. For example, an insulating sleeve may cover one or more portions of the earpiece(s) (e.g., the portion of an earpiece that remains outside the ear canal of a patient during use may be covered in an insulating sleeve to reduce heat transfer between the earpiece and the outer ear of the patient). The insulating covering may comprise any suitable material, including, but not limited to, coating materials that must be reapplied to the earpiece(s) before each use (e.g., mineral oil, polypropylene, gels and the like) and reusable coating materials (e.g., a thermally insulative sheath or sleeve). In some embodiments, the thermally insulating covering comprises a silicone sleeve.
Earpieces of the present invention may comprise an electrically insulating covering. For example, an electrically insulating coating may cover one or more portions of the earpiece(s) (e.g., the portion of an earpiece that is inserted into the ear canal of a patient during use may be coated with an electrically insulating coating to prevent electrical conductance between the earpiece and the ear canal). The electrically insulating covering may comprises any suitable material, including, but not limited to, metal oxides (e.g., aluminum oxide), glass, porcelain and composite polymer materials. In some embodiments, the surface of an earpiece comprising aluminum is anodized to produce an aluminum oxide coating that electrically insulates the surface of the earpiece.
Earpieces of the present invention may comprise a protective coating. For example, a protective coating may cover one or more portions of the earpiece(s) (e.g., the portion of an earpiece that is inserted into the ear canal of a patient during use may be coated with a protective coating to prevent the underlying surface of the earpiece from coming into contact with the surface of the ear canal during use). The protective coating may comprise any suitable material, including, but not limited to, metals and metal alloys (gold, silver, copper and alloys thereof).
As will be appreciated by one of skill in the art, earpieces of the present invention may comprise a single covering/coating that fulfills multiple purposes. For example, the a thermally conductive coating applied to the portion of an earpiece that is inserted into the ear canal of a patient during use may also prevent the underlying surface of the earpiece from coming into contact with the surface of the ear canal during use.
As will be appreciated by one of skill in the art, earpieces of the present invention may comprise multiple coatings. For example, the earpiece(s) may comprise both a thermally conductive covering and a thermally insulative covering (e.g., a thermally conductive cushion may cover the portion of an earpiece that is inserted into the ear canal of a patient during use and an insulating sleeve may cover the portion of an earpiece that remains outside the ear canal of a patient during use).

The pressure-relief channel 123 may be of any suitable length and depth (i.e., any length/depth that is sufficient to provide air flow from the interior of the ear canal at the distal tip of the earpiece to the external air outside of the ear canal during and/or after insertion of the earpiece 12). For example, the pressure-relief channel 123 may be generally as long as a side of the earpiece 12 and may be about 0.5 mm to about 2.0 mm deep. The pressure-relief channel 123 may be located in any suitable location in/on the earpiece (e.g., embedded in an outer surface of earpiece 12 or passing through the interior of the earpiece 12 so as to provide a conduit between the interior of the ear canal and the exterior environment).

The present invention is explained in greater detail in the following non-limiting Examples.
A male subject in his forties and good health, naïve to CVS, was administered cold CVS to his right ear in a square waveform pattern. The pattern was of cooling to 10 degrees Centigrade (as compared to normal body temperature of about 37 degrees Centigrade) as a “step” function or “square wave” with one symmetric square wave being delivered for a time period of 20 minutes. The subject was observed by others to be slurring his words, and was asked to remain seated for a time of two hours following the treatment session as a precaution. Otherwise, no long-term deleterious effects were observed.
The same subject described in EXAMPLE 1 was subsequently treated by administering cold CVS to the right ear in a sawtooth waveform pattern of cooling to 20 degrees Centigrade (as compared to normal body temperature of about 37 degrees Centigrade) in a symmetric sawtooth waveform pattern, without gaps, at a frequency of one cycle or waveform every five minutes, for a total duration of approximately 10 minutes and a delivery of a first and second waveform. Unlike the situation with the square wave pattern described in Example 1, the subject continued to perceive the temperature cycling up and down.
The same subject described in Examples 1-2 was administered cold CVS to the right ear as a sawtooth cooling waveform at different amplitudes in a titration study. A maximum perceived sensation of cyclic cooling was perceived at a peak amplitude of about 17 degrees Centigrade (or cooling from normal body temperature to a temperature of about 20 degrees Centigrade). Cooling beyond this did not lead to additional gains in the sensation of cyclic cooling perceived by the subject.
Modeling of the human vestibular system indicates that the cupula (the structure within the semicircular canals pushed by the movement of fluid therein and which contain hair cells that convert the mechanical distortion to electrical signals in the vestibular nerve), is stimulated by CVS at chilling temperatures of 5 or 7 degrees Centigrade below body temperature.
Modeling of the human vestibular system indicates that a slew rate faster than 20 degrees Centigrade per minute (which would enable one 20 degree Centigrade waveform every two minutes) is not useful because the human body cannot adapt to temperature changes at a more rapid rate. While maximum frequency is dependent in part on other factors such as waveform amplitude, a maximum frequency of about one cycle every one to two minutes is indicated.
Modeling of the human vestibular system indicates that a continuous, time-varying waveform is most effective in stimulating the vestibular system, as stagnation and adaptation of the cupula is thereby minimized. While minimum frequency is dependent in part on other factors such as the waveform amplitude, a minimum frequency of about one cycle every ten to twenty minutes is indicated.
To permit delivery of at least a first and second waveform, a duration of at least one or two minutes is preferred. As noted above and below, results have been reported by patients with treatment durations of ten and twenty minutes. Hence, as a matter of convenience, a treatment session duration of not more than 30 or 40 minutes is preferred (though longer sessions may be desired for some conditions, such as acute care situations).
A female patient in her early fifties with a long standing history of migraine suffered an acute migraine episode with symptoms that consisted of a pounding headache, nausea, phonophobia, and photophobia. Right ear cold CVS was performed using the sawtooth waveform, essentially as described in Example 2 above, with a temperature maximum of 17 degrees Centigrade (chilling from body temperature) for 10 minutes (for a total delivery of two cycles). At the conclusion of the treatment the patient reported that her headache and associated symptoms were no longer present. At a reassessment one day later, the patient reported that the headache had not returned.
The same subject described in examples 1-3 suddenly developed an episode of extreme urination (10 liters per day), thirst for ice water, and associated fatigue. Urinary testing suggested the onset of diabetes mellitus, for which there was strong family history.
The patient's initial weight as taken at his primary care physician indicated a recent 20 pound weight loss. The first attempt to obtain a glucose reading from the patient resulted in an out of range result (this result typically occurs with glucose levels in excess of 600 mg/dl). The patient was hospitalized and received hydration and IV insulin therapy. The patient's first glucose level after this treatment was 700 mg/dl. The glucose level were brought down to approximately 350 and treatment with an oral antihyperglycemic agent was initiated.
Follow-up care after hospital discharge with the subject's primary care physican expanded the oral antihyperglycemic agent therapy to include both metformin and JANUVIA™ sitagliptin. In addition, a strict exercise program of 30-45 minutes 5 to 6 days per week and diet control were instituted. Daily glucose levels via finger stick were taken 2 to 3 times per day.
At this point the patient's baseline hemoglobin A1c (Hb A1c) level was 9.8%, as compared to normal levels of 5 to 6%.
The patient then began daily treatment with CVS. The treatment was carried out for a time of ten minutes, once a day for about a month, after which the treatment was continued two to three times a week for three additional months (with each treatment session being about 10 minutes in duration). The CVS was delivered to the patient's right ear, as a sawtooth cooling waveform as described in Example 2. At the conclusion of these treatments, the patient's BB A1c level was 5.3%. As a result, the patient was removed from all hypoglemic agents.
Most oral antihyperglycemic agents lower a patient's Hb A1c level by approximately 1 to 2% (see generally S. Inzucchi, Oral Antihyperglycemic Therapy for Type 2 Diabetes, JAMA 287:360-372 (Jan. 16, 2002)). In contrast, this patient's initial value was 9.5, and dropped to 5.3.
The sawtooth waveform described in the examples above was symmetric and linear, as illustrated in

It was noted that a patient who was sitting up (watching television) and receiving a cold CVS treatment reported perceiving a different effect than perceived in prior sessions. Upon reclining to about 45 degrees, she did receive the earlier effect.
The “standard” angle of recline for diagnostic CVS is about 60 degrees (or equivalently 30 degrees above horizontal). The reason for this positioning is that the “horizontal” SCC is tilted up by about 30 degrees (higher on rostal side) (More recent x-ray measurements put the angle at closer to 20+/−7 degrees.) The intent with diagnostic CVS is to reorient the horizontal SCC so that it is substantially vertical, thus maximizing the effect of the convective flow set up by calorics.
Hence, if the subject is reclined to about 20 degrees above horizontal (and supine), then a cold stimulus leads to inhibition or a phasic rate less than the tonic rate. For a warm stimulus, this situation is reversed (phasic rate increases above tonic).
Further, cold simulation tends to activate principally the contralateral brain structures whereas hot leads to principally ipsilateral activation. For example, in V. Marcelli et al. (E
Empirical tests and modeling indicate that approximately 20 degrees Centigrade absolute cooling (17 degrees Centigrade below body temperature) is the lower limit beyond which the cupula is maximally deformed and therefore the phasic rate change is maximal. On the warming side, more than about 7 degrees Centigrade or so above body temperature becomes uncomfortable. This level of temperature heating within the ear canal will not lead to maximal deformation of the cupula. Therefore, there is an asymmetry in terms of ability to span the full frequency spectrum of phasic firing rates. However, the increase in the phasic firing rate is not constrained in the manner of a decrease—that is, the phasic firing rate can only approach zero, relative to the tonic rate of roughly 100 Hz, whereas the phasic rate can exceed 200 Hz.
Since inverting the patient changes the sign of the inhibitory/excitatory motion of the cupula, the following can be seen: Using a cold stimulus, of 20 degrees Centigrade absolute, but now orient the patient so that his head is tilted forward by from 75 to 20 degrees from the vertical position. This will invert the horizontal SCC relative to the image above and now the cold stimulus will result in an excitatory increase in the phasic firing rate. For clarity, tilting the head forward by 20 degrees makes the horizontal SCC substantially horizontal. Tilting beyond that now starts to invert it so that at 110 degrees (tilted forward), the horizontal SCC will be in a vertical orientation, but now 180 degrees flipped from what is used in conventional diagnostic CVS. So, the “general rule” for treatment of having the patient reclined by 45-90 degrees can be expanded to include “tilted forward” by 75-120 degrees.
Thus a protocol is seen where, using only cold stimulus, one can cover the entire range of phasic firing rates simply by reorienting the patient at the appropriate points during the time course of treatment.
Note that this type of inversion should also lead to an inversion in the side of the brain that is primarily activated. Specifically, if cold stimulation leads to principally contralateral activation in the “rightside up” orientation, then it should lead to principally ipsilateral activation in the “upside down” orientation.

a=“thermal diffusivity” of temporal bone (mm2/sec); this may vary in patients, but compact bone paths will dominate the thermal. The literature lists values from 0.14-0.25, but this is based on the onset of nystagmus as the “stimulation time.” Marcelli et al. showed a much faster, actual brainstem activation time after CVS, which did not relate to the onset of nystagmus. Literature estimates for the thermal diffusivity of hard bone range from 0.45-0.55 to 1.6. A value of 0.5 is assumed here, based on x-rays of the compact, wet bone in the region of interest.
x=the effective thermal distance (mm) between external ear canal and the edge of horizontal semicircular canal; default=7.5 mm

tn=time at which new stimulus starts.
Default values for the constants are listed next to the definitions. CVS application times that are short compared to the response time of the patient may not be very different from a longer pulse at a lower temperature due to thermal smoothing effects. Literature reports of the maximum phasic firing rate are about 100 Hz. That is, +/−100 Hz away from the tonic firing rate, which is on the order of 100 Hz. The maximum deformation of the cupula at its center is, correspondingly, about 77 microns. Thermal gradients that imply a deformation greater than this value would tend to lead to saturation of the phasic firing rate. At the other end of the scale, the minimum detectable volume change in the SCC is on the order of 25 picoliters and this corresponds to a change in the phasic rate of roughly 0.5 Hz. This indicates a minimum temperature gradient across the SCC of ˜0.02 degrees Centigrade. The obvious requirement is that the body's homeostatic temperature regulation must ensure a constant temperature across the 6 mm wide canal to a value on that order.
Another simplification used in the model was to ignore the temperature dependence of the bulk coefficient of thermal expansion of water (with the simplifying assumption that endolymph has roughly the thermal properties of water). This assumption will lead to an apparent saturation of the phasic firing rate at higher temperature (roughly 27 degrees Centigrade) than will actually occur. Below body temperature, the phasic rate may not saturate until the lower 20's.
The volume of the horizontal SCC is estimated to be: 3.2E-3 cc. The change in volume due to a temperature difference ΔT is: 3.8E-4*3.2E-3*ΔT=1.22E-6 ΔT.
The volume of the “lens” of the cupula when deformed to its maximal (saturation of the phasic firing rate) extent is roughly: 4.4E-6 cc Therefore, the change in the phasic rate: Δf=27.7*ΔT in Hz.
The relationship between the applied thermal waveform and the phasic firing rate of the afferents of the vestibular branch of the 8th cranial nerve can thus be modeled for a square waveform stimulus (such as in Example 1 above), and for a time-varying, saw tooth, waveform stimulus (such as in Example 2 above).
It was noted that there is little distortion of the time-varying waveform of, as compared to the square waveform, because the body can track the more gradual temperature changes.
There is a tendency for the values to skew a small amount vertically (e.g., the temperature delta goes slightly above body temp at points). This effect appears to be non-physical and is simply a limit of the approximate model employed. The same appears true of the firing rate going positive.
The “tips” of the sawtooth waveforms appear to exceed the maximum change in phasic firing rate of 100 Hz (this is seen in the square wave as well). This may be because the coefficient of thermal expansion of the endolymph changes with temperature and was not corrected in the model above. This would result in an overestimate of the firing rate for a given temperature in the plot. Therefore, the firing rate may not, in fact, saturate (i.e., will stay below a delta of 100 HZ) at 20 C. The loss of a sense of improvement reported in Example 3 above for temperatures below about 17 to 20 degrees Centigrade may be due to the cupula of the vestibular canal “pegging” (achieving its maximal physical distortion) and the firing rate saturating.
A female subject was a headache sufferer with a 10-year history of debilitating, chronic migraines, the last five being refractory. She had failed all pharmaceutical interventions. The patient underwent an occipital nerve stimulator implant for headaches, with good symptom-management for approximately one year, at which point the device was no longer effective. Co-morbid with her migraine headaches was depression, which was only partially responsive to pharmaceutical management. Subject was placed on disability from her employment.
The subject was treated using a five-day therapy paradigm consisting of daily treatments comprising a square waveform pattern of cooling to 20 degrees Centigrade, at a frequency of one cycle every ten minutes, for a total duration of ten minutes while the patient was in a reclined position of thirty degrees above horizontal. Video images of the subject were captured before, during and after each treatment session and were used to assess the effectiveness of the treatment (e.g., by assessing the patient's mood).
For all active, in-process migraine episodes, within 5-15 minutes after completion of a treatment, subject experienced pain attenuation. Chronic headache indication was alleviated on the 4th day of treatment, with concurrent progressive improvement in her mood over the course of the five days. The treatment course peaked at day 5. The subject became pain-free, with complete resolution of mood symptoms. She remained pain-free for 63 days after the therapy was completed, at which time her migraine headaches began to recur, but without return of clinical mood symptoms.
The five-day therapy paradigm was repeated. The subject responded more quickly to this second longitudinal therapy, with her chronic headaches disappearing on the 3rd day of treatment. She remained pain-free for five weeks.
Later, the patient was treated with a sawtooth waveform (lower temperature of 20 degrees Centigrade) employing a daily treatment duration of 10 minutes. By the end of the treatment week, the patient was pain free (using a 0-3 pain scale where 3 is severe, 2 is moderate, 1 is mild, and zero is no pain). Charted pain scores (not shown) showed improvement after treatment. All CVS treatments were to the right ear using cold stimulation. Additionally, after each treatment week, the patient stayed pain free for times varying from 2-9 weeks. The patient additionally reported feelings of high energy and resolution of co-morbid depression.
The same subject described in example 8 had right ear CVS treatment using a heating, to approximately 42-43 degrees, sawtooth waveform for 10 minutes, with a contiguous repeat for an additional 10 minutes. The treatment was effective in resolving her acute migraine pain. Additionally, the treatment had a soporific effect but also caused slight dizziness. The subject did not note the feeling of dizziness in example 8 using cold stimulation.
The same subject described in example 1 underwent the same CVS treatment described in example 14. He too reported a feeling of slight dizziness that was not apparent during cold CVS stimulation.
A female subject in her late 30's had a history of migraine with associated vertigo (vestibular migraine). The subject has a history of vestibular dysfunction and slight co-morbid depression. The subject was treated on a near daily basis, between 20-40 minutes per day, with cold stimulation (down to 20 degrees Centigrade) CVS before switching to warm CVS, with a maximum temperature of 48 degrees Centigrade. All CVS treatments used a sawtooth pattern with left-ear stimulation due to more severe vestibular dysfunction in the right ear. This subject did not note dizziness as a side effect of the warm CVS treatment, suggesting that her vestibular system, due to dysfunction, is more immune to CVS (and thus she must treat more aggressively to gain benefit). A parent of the subject commented on a change in the subject's speech and “spirit” during phone conversations while using cold CVS. The switch to warm CVS resulted in additional mood and motivational elements. Colleagues commented on enhanced interpersonal interactions and an increased sense of confidence. The subject stated: “for the last couple of year I've felt as if my brain has burnt out, it feels so much better since the warm treatments.”
A male in his 40's developed sudden onset migraine with vestibular dysfunction that led to effective disability and inability to go to work. The subject was not helped by medications and sought the advice of multiple physicians at two prominent academic research hospitals. The subject was treated on a near daily basis for 10-20 minutes a day with cold CVS (down to 20 degrees Centigrade) CVS before switching to warm CVS, with a maximum temperature of 42 degrees Centigrade. The subject, like the subject in example 16, did not experience dizziness with the introduction of warm CVS treatments, possibly associated with the vestibular dysfunction accompanying his migraines. CVS treatments are soporific for this patient. The subject's wife notes a pronounced change since CVS treatments were started. Whereas prior to CVS treatment the subject was loath to get out of bed, since CVS treatment the subject has returned to part-time work with his employer.
The same subject described in example 9 switched from cold CVS to warm CVS for the control of his type II diabetes. He treated with a sawtooth waveform that oscillated between 34 and 43 degrees Centigrade. The average heating slew rate was typically above 40 degrees Centigrade/min and the average cooling slew rate was typically greater than 10 degrees Centigrade/min. Since commencing CVS therapy, the subject has stopped taking medications, which were previously necessary to maintain serum glucose near a normal range. At the time of diagnosis, the subject's A1c value was 9.8. At the time shown at the end of the chart below, that value was reduced to 5.6 (again, with no medications). A1c is viewed as a better long-term marker of diabetes control than serum glucose (it doesn't fluctuate). The normal range is about 4-6. For diabetics, the recommendation is that anything below 7 is a good target. A record of the subject's serum glucose readings (not shown) indicated possible additional improvement realized with the switch from cold to warm CVS in terms of reduced variability. The subject also had a gingival abscess during the period shown and such infections can lead to oxidative stress and impaired glucose control (see generally J. Southerland et al., Diabetes and Periodontal Infection: Making the Connection, Clinical Diabetes 23, 171-178 (2005)). The infection did not disrupt the subject's glucose maintenance.
Glucose readings taken at 7 AM and 10 PM; CVS treatment in evening. Treatment 1: 34 to 17 degree C. sawtooth waveform, 20 minute duration. Treatment 2: 34 to 43 degree C. sawtooth waveform, two 20 minute treatment per day. Glucose levels are more controlled with treatment 2. No other diabetes medications were in use during the testing period. The subject reported that the warm sawtooth CVS differed slightly from the cold sawtooth CVS in that it appeared to have increased potency as noted by the feeling of increased dizziness and mild nausea, which appear consistently with each treatment. Glucose levels tend to drop 10-30 points approximately 60 minutes or more after the treatment. The subject reported that combining exercise in proximity to the TNM therapy appeared to cause a glucose decrease of 30 to 50 points.
A male in his mid 60's was wounded three times as a Medic in Vietnam and had a history of post-traumatic stress disorder. His manner is described as introverted and his mood depressive. After the commencement of cold CVS treatments, the subject's wife reported that he started becoming more extroverted. She reported that “she did not know who this person was speaking to her this morning”; that he was planning getting together with friends; that usually he would only do this if forced; that he expressed interest in going to Africa for a photo safari; that she started thinking “where is my husband?” After a second treatment, the subject reported continuous sleep throughout the night (usually he would usually wake up 3-4 times). He commented that “insomniacs should use this.” The subject reported feeling energized. The subject was usually unable to recall dreams, but awoke with visual flashback of events in Vietnam, not unpleasant just old visual memories, and returned to sleep. The subject traditionally avoided driving but now is driving with substantially less hesitation. The subject is a serious amateur painter and both the subject and his spouse report significant positive developments in his painting style and productivity since commencement of his CVS. Upon interruption of CVS therapy, PTSD symptoms gradually returned almost to baseline one week after CVS stopped.
The patient of example 19 has type II diabetes. After the commencement of CVS therapy he became much more responsive to oral hypoglycemics, has had to cut dose significantly (data not shown).
The patient described in example 18 above was administered three different waveform CVS stimuli, as follows:
Nystagmus is the name given to involuntary eye movements enabled by the so-called vestibulo-ocular reflex (VOR). CVS provides an artificial means to activate the VOR. By tilting the head (˜20 degrees above the horizontal), the horizontal SCC is placed in a vertical orientation. Creating a differential temperature across this canal results in convection currents that act to displace the cupula. Warm CVS leads to cupular displacement such that the phasic firing rate increases whereas cold CVS leads to a decrease in the firing rate. Further, warm CVS results in nystagmus that is manifested by a rapid movement of the eyes towards the simulated ear. Cold CVS results in the rapid phase of nystamus away from the stimulated ear. Therefore, by noting the existence and the direction of nystagmus, one may determine that the VOR is being activated and whether the phasic firing rate is greater than or less than the tonic firing rate.
The use of continuous CVS irrigation or stimulation at a constant temperature will induce nystagmus, but after a time on the order of 2-3 minutes (e.g., Bock et al., Vestibular adaptation to long-term stimuli, B
It is an aspect of the current invention that the use of time-varying thermal waveforms enables the persistent stimulation of the vestibular nerve afferents, beyond the time period at which adaptation to a constant thermal stimulus occurs. In this example, the present invention has been used to generate nystagmus over a 12 minute period as measured by videonystagmography and by electronystagmography. A sawtooth cooling waveform going between temperatures of 34 to 20 degrees Centigrade was applied to the right ear of a subject who was reclined such that his head was ˜20 degrees above the horizontal. Electronystagmography was used to measure the movement of his eyes, and demonstrated the existence of nystagmus both early in a 12 minute period and near the end of the 12 minute period (data not shown).
The purpose of this Example is to find a robust marker of successful CVS induction of relevance to neurological treatments. The study is being performed on rats using a modified version of a dual ear CVS unit. Specifically, ear bars that are connected to TEC's are placed in the ear canals of rats that have been anesthetized. The device has dual ear stimulation capability.
Methods and Results:
Single ear CVS: Rat #9 received a sawtooth waveform in the right ear that oscillated between 36 and 14 degrees Centigrade for 60 minutes (not shown). The rat was anesthetized with isoflurane. It should be noted that anesthesia may lessen the effects of CVS to a degree. The rat was oriented horizontally, which places the horizontal semicircular canal in the vestibular bodies at a roughly 30 degree tilt upwards on the anterior side. After the end of the 60 minute right ear stimulation, the same caloric waveform was then applied to the left ear. The response of the regional cerebral blood flow was measured on the right parietal region of the skull via a laser Doppler probe affixed to the skull. Roughly 30 minutes after the start of right ear CVS, the oscillation in blood flow became pronounced. The period of the sawtooth temperature waveform is 1.9 minutes. As observed (using nearest neighbor averaging), the period of the modulation in blood flow is longer, by about 30 seconds on average (data not shown). This suggests that the driving force (the CVS) leads to modulation of the blood flow via a mechanism that stays in a non-equilibrium state. That is, the rat's response does not simply match the period of the CVS waveform and is instead adapting to it dynamically. At the end of right ear CVS, the oscillations stop. Roughly 35-40 minutes after the start of left ear CVS, clear oscillations once again appear, though diminished in amplitude relative to right ear stimulation. This is presumably due to the fact that left ear stimulation has a weaker effect on blood flow in the right portion of the brain. Serrador et al. (BMC Neuroscience 10, 119 (2009)) note that “connections have been found between the vestibular nuclei and the fastigial nucleus . . . followed by vasodilatory connections to the cerebral vessels.”
Control Run:
The Vestibular stimulation device was placed on the rat, but was not activated. No oscillations in rCBF were seen (the downward drift in the flow data is due to a slight shift in the baseline of the probe).
Dual Ear, Same Waveform:
Rat #12 had CVS delivered to both right and left ears simultaneously (not shown). The waveforms were not tied in phase and tended to become out of phase during the bulk of the 60 minute treatment period. No modulations in rCBF were manifested (data not shown).
The dual ear stimulation data suggest that the application of the same waveform to both ears simultaneously acted to cancel out any net modulatory effect on rCBF. However, it is still the case that the same stimulation was given to the vestibular nuclei as when only single ear CVS was used. Nystagmus, would also not appear if the same CVS stimulation were applied to both ears since the phenomenon, mediated by the vestibulo-ocular reflex (VOR), requires a differential input to the two horizontal SCC's. Thus the absence of rCBF modulation does not mean that the fastigial nuclei (both nuclei for dual ear CVS) are not being stimulated. Rather, their combined activation yields no net effect on rCBF. Since modulation of rCBF is not a necessary aspect of CVS induced neuroprotection (it is a marker of CVS induction), CVS therapy may actually be as or more effective with dual ear stimulation.
Dual Ear, Different Waveforms:
Run 17 simultaneously applied a 34 to 44 C sawtooth waveform to the right ear (period of ˜40 seconds) and a 34 to 13 C sawtooth (period ˜1.7 min.) to the left ear (not shown). In this case, flow modulations were seen and they persisted well past the end of the CVS treatment period (not shown). In this case the flow effect, with different temperatures applied, not only was present but continued to oscillate after the end of the active CVS treatment.
Discussion:
The vestibular systems of all mammals act in the same way. Therefore, the results of the rat study discussed above have implications for human CVS therapy as well. The conclusion from the study is that the most likely cause of the modulation seen in rCBF is that CVS does stimulate the fastigial nucleus in the cerebellum.
EEG is useful in identifying cortical activation associated with CVS. Therefore, EEG is useful as a non-invasive means to titrate CVS therapy. This report summarizes EEG data acquired in a rat study.
Methods and Results:
The report on regional cerebral blood flow changes in a rat during various CVS treatments has been generated. In this summary, EEG electrodes were placed in the scalp of the rat, differential pairs being applied on either side of the midline of the skull. (data not shown).
Discussion:
The activity observed in the theta band was markedly different between the 3 states. For the low flow state, activity was depressed. The high flow peaks were shifted to lower frequencies as compared to the baseline (pre-CVS). In the 0-40 Hz plot, the high and low flow peaks in the low-30 Hz range overlap whereas the baseline peak is shifted (this is likely due to a difference in somatosensory perception during CVS versus pre-CVS). The sensitivity of EEG spectra to the details of CVS delivery suggest that EEG is an effective tool for evaluating the difference between CVS waveforms and for titrating them.
Heart rate variability seems to be a significant marker of health and systems for measuring it non-invasively are becoming common. This report describes the use of the ithlete, a commercial HRV measurement instrument that runs as an smartphone software program, or “app.”
Methods and Results:
The subject is a 40-45 year old male diagnosed with seasonal cluster headaches. The device used to measure HRV is the ithlete (HRV Fit Ltd., Hants UK)) which uses an iPhone as the recording/readout device and a chest strap with sensors that monitor heart rate. The HRV parameter is calculated via a proprietary algorithm that takes the raw heart rate data as input. Note: of course there are many devices that will measure HRV and the ithlete was chosen only as a low cost and convenient system. Proper HRV is used as a metric of proper cardiac health (good health implies adequately high HRV; e.g., Malik, Heart rate variability: standards of measurement, physiological interpretation, and clinical use, E
The CVS treatment was a 42 degrees Centigrade sawtooth wave applied to the left ear and a 17 degrees Centigrade sawtooth applied to the right ear. The treatment lasted for 10 minutes. HRV data were recorded immediately after the end of the treatment. HRV is a dimensionless measure. During the October 24th test, average HRV dropped by 30% and on October 28th by 27% (data not shown).
Discussion:
HRV is proposed as a marker of effective CVS induction and could thus be used as a tool for titrating CVS dosing. Pathological conditions (such as cluster headaches discussed here) can lead to elevated HRV levels. Other pathological conditions, e.g., cardiac insufficiencies, are often associated with abnormally low HRV values (for that individual).
A subject (also female, age 50-55) was diagnosed with fibromyalgia 3 years ago. Multiple allopathic and homeopathic interventions provided no substantive relief. The subject has co-morbid migraine headaches.
Methods and Results:
The subject underwent CVS treatment in the right ear, with a 17 degree C. sawtooth waveform.
From September 13-19 the subject stopped CVS treatment due to significant pain and inability to function. On September 20 the subject began treatments twice per day, sometimes using a 3rd daily treatment using the CVS parameters listed above. She realized an improvement in both migraine pain and pain from fibromyalgia. In the September 28-30 timeframe thunderstorms seemed to trigger additional migraine pain, but this abated over the following days until her pain level was barely noticeable.
The subject commented upon starting twice-a-day treatments: “I′m writing to report excellent results using 2 treatments. Last night I tried 2 consecutive treatments, and I felt great! Like I′d been to a spa and had a relaxing massage and soak in the hot tub.”
The subject reported on September 26th: “This weekend I was able to work with [husband] getting 14 new bushes in the yard and picking out new paint at Lowe's to repaint the shutters on the house. I′m so very hopeful and happy. Gardening is a shared passion for us, and the first two years here, I wasn't able to even water the plants, so the ones left are real survivors! I feel like you are giving me my life back, and giving [husband] his wife back”
When the subject's spouse was asked if the Vestibular stimulation device was truly helpful he responded: “Nothing in the last 3 years had helped before this.”
After October 6, the unit was retrieved. The subject has since returned to baseline.
A female subject underwent spinal surgery and sustained damage to the spinal cord. Thereafter she has had intractable peripheral neuropathy (foot pain) over a roughly 4 month period that had not responded to analgesics. The subject has obtained relief using CVS, with the extent and duration of relief depending on the device used and the waveform details.
Methods and Results:
The subject underwent CVS treatment with the following chronology:
Discussion:
The subject received extended (multiple day) pain relief from one 10 min session using dual ear CVS. Single ear CVS, using a sawtooth waveform (slower slew rate) and an early device (basically a single cold/warm square wave), led to partial pain reduction for a time limited to hours. Therefore, the dual ear CVS treatment was superior to single ear for pain reduction. This subject and another have stated that the mixed waveform, dual ear (e.g., example 4) results in more significant subjective sensations (deep relaxation/sleep for this subject, increased nausea for the other). It is unclear with this single case if the mixed waveform treatment leads to increased pain reduction efficacy (both dual ear treatments were significant).
This Example evalutes the feasibility of using a portable CVS unit in a home setting over a month or more. The hypothesis was that daily CVS treatment would reduce the overall pain level and frequency of headaches.
Methods and Results:
The subject is a 50-55 year old female with a history of 6-8 migraine headache days per month (a month is taken as 28 days when reporting on migraine frequency). The subject used a right-ear Vestibular stimulation device and a sawtooth waveform that went from 34 degrees Centigrade to 17 degrees Centigrade with a period of roughly 1.7 minutes. The duration of the treatment was 10 minutes per session (daily sessions, moving to every other day after about 2 weeks of treatment). The average slew rate for heating was 40 degrees Centigrade/minute and the average slew rate for cooling was 14 degrees Centigrade/minute.
The subject experienced a decrease in pain over the first week of therapy. (pain score data not shown). In the 40 days past the one week transitionary period, the subject had only one migraine headache (again, to qualify as a migraine it must be at a pain level of 6 or more on a scale of zero to ten and last for 4 hours or more). The one headache occurred during unusual stress associated with a transatlantic trip and disruption of work schedule upon her return. The subject also noted a subjective improvement in co-morbid depression over the treatment period.
The intent of this report is to show experimental evidence of the control of glucose levels by adjusting the frequency with which CVS is used in a subject with type II diabetes.
Methods and Results:
The subject is a 40-45 year old male diagnosed with type II diabetes within the last two years. As reported earlier, the subject has been able to forego the use of medications to control serum glucose levels, using CVS therapy instead. Recently, the subject has started using dual ear CVS, with a warm time-varying waveform applied to one ear and a cold time-varying waveform applied to the other. The dual ear therapy reduced the frequency with which the subject needed to use CVS in order to control serum glucose levels (data not shown). Dual ear CVS was used with a 17 degrees Centigrade square wave for the right ear and a 42 degrees Centigrade sawtooth on the left ear. Each point in the graph represents a daily measurement (consistent time during each day). The red lines show when CVS was used. As the glucose levels were tracked, they would tend to move up in between CVS treatments, thus signaling when another treatment should be applied. This feedback method should be able to be extended to other patients, using their specific glucose levels to titrate frequency and intensity of CVS treatments. This subject remains off any other medications to control glucose levels.
Discussion:
This is an update report to supplement accounts from this subject already included in the Examples above, and further shows that serum glucose is a useful metric for CVS titration.
As the CVS treatment device has evolved, we have moved from single to dual ear stimulation and have increased the slew rate to allow waveforms to be played out at a higher frequency. This report lists subjective metrics that can be used to assess the strength of CVS stimulation for a given subject.
Methods and Results:
The subject is a 40-45 year old male using CVS therapy chronically for type II diabetes and seasonal cluster headaches. He ranks the level of intensity of the CVS experience as follows:
Discussion:
The most significant metrics for CVS therapy for pain patients is its effects on pain level and relative side effects. This report recounts observations by one subject that can serve as a paradigm for how other patients can be assessed in the clinic. The right titration will involve an on-going assessment of effects on symptoms (e.g., pain) and minimization of unwanted, lasting side effects (for clarity, the side effects reported above are transient). There are tradeoffs that patients can make between efficacy with more intense side effects balanced against less frequent need to treat.
The following parameters can be varied in a dual ear system:
A common report from users of the Vestibular stimulation device is that they have beneficial effects in terms of sleeping soundly. It is known (e.g., Horii et al., J. N
Methods and Results:
The reports of the soporific effects of CVS with subjects is variable and subjective. Listing the claims by subjects in order of frequency:
The intent with this study was to evaluate using the Gen 2.0 CVS unit (left ear only, same earpiece but different (less powerful) TEC (thermoelectric cooler or Peltier cooler) than will be used in Gen 3 device) in a single session to observe any effects on spike activity in epileptic patients as monitored by EEG.
Methods and Results:
The subjects were treated with a sawtooth waveform that went from 34 degrees Centigrade to 17 degrees Centigrade (left ear only). Note that the actual temperature profile was not the same for all patients. For patient 3, the average slew rate on heating was around 14-15 degrees Centigrade/min and the cooling rate dropped from about 5.8 degrees Centigrade/min to 4.5 degrees Centigrade/min (not shown). It can be seen that more time was required to in the second “dip” to get to 17 degrees Centigrade. This is due to insufficient power in the Gen 2.0 Vestibular stimulation device.
For patient 4, the inadequate power of the unit is even more apparent. The average heating slew rate was about the same as with patient 3, but the cooling rate started at 4.2 degrees Centigrade/min and dropped to 3.6/min (not shown). The device failed to reach the 17 degrees Centigrade target temperature.
The spike rate was measured by continuous EEG before CVS treatment and after CVS treatment (data not shown). The decrease in spike rate lasted from 1-2 hours for each of the four patients. The reduction in spiking ranges from 21-32%.
Discussion:
despite the underperformance of the Gen 2.0 model, primarily caused by an older, less powerful TEC and the lack of a cooling fan on the heat sink, demonstrable effects were seen in all 4 patients in terms of a reduction in spike activity that persisted past the end of the CVS treatment session. At this time, we don't have the ability to try a more advanced device (e.g., Gen 2.5) with these patients. A logical course would be to treat the patients longitudinally to see if the effects of CVS could be made more lasting. Despite the challenge of performing CVS on this population (age range from 6-10 years old), it was accomplished and there were no side effects of the treatment.
