BACKGROUND
Low or reduced baroreflex sensitivity in patients is associated with numerous problems and disorders (e.g., hypertension, congestive heart failure, coronary heart disease, hypertension, depression, alcohol or drug use disorders and aging). Reduced baroreflex sensitivity in patients blunts the flexibility of the body's self-regulatory system. Contrariwise, high baroreflex sensitivity in patients is generally associated with health and wellness.
What is needed, therefore, are efficacious and cost effective means and methods for increasing baroreflex sensitivity in patients.

DETAILED DESCRIPTIONS OF SOME EMBODIMENTS
Described herein are various embodiments of vibration stimulation therapy systems, devices, components and methods that are configured to trigger or induce resonance or high amplitude oscillations in a cardiovascular system of the patient.
The arterial baroreflex system (BRS) is a reflexive control system that counteracts acute shifts in blood pressure (BP) by invoking compensatory reactions in cardiovascular functions (e.g., heart rate (HR), vascular tone (VT), and stroke volume (SV)). Baroreceptors trigger simultaneous reflexive reactions in HR, VT, and SV. The BRS regulates short-term BP serving to protect the brain from stroke and the heart from myocardial infarction as well as to restore its inhibition-excitation balance. Low or reduced baroreflex sensitivity is often associated with numerous problems and disorders, such as hypertension, congestive heart failure, coronary heart disease, depression and aging. Reduced baroreflex sensitivity blunts the flexibility of the regulatory system, whereas a high sensitivity is associated with health and wellness.
Similar to engineering closed loop control systems with delays, the closed loop baroreflex system has been discovered to possess resonance properties. That is, there are certain frequencies (known as resonant or resonance frequencies) at which stimulation of the baroreflex system can elicit high amplitude oscillations in HR, BP, SV, and/or VT. The value of the delay in the feedback control system can be used to define one or more resonant frequencies in the closed loop control system. In one such embodiment, the period of the resonant oscillations is equal to the value of two delays. In a closed loop baroreflex system, periodic driving forces at one or more resonant frequencies can produce much larger amplitudes. This is because a baroreflex system is characterized by delays between changes in BP and HR (˜5 seconds), as well as between BP and VT (˜10-15 seconds), and can have, by way of example, resonance frequencies of ˜0.1 Hz and ˜0.03 Hz (i.e., periods of resonance oscillation are ˜10 s and ˜30 s). Each person's baroreflex system has own delays and accordingly own resonance frequencies. These changes can coincide in some fashion with, or can be proportional to, certain resonant frequencies.
Some studies have revealed that interventions such as slow meditative breathing and progressive muscle relaxation performed at or near a patient's resonant frequency can increase oscillations at these frequencies and increase short-term HR baroreflex sensitivity, vagal tone, and/or heart rate variability. This is especially so in healthy individuals and in patients who suffer from cardiovascular or autonomic nervous system disorders. Like many systems, the cardiovascular system has many different functions, and is characterized by several distinct resonant frequencies.
As noted above, according to Vaschillo and colleagues (2010), the baroreflex system in humans can demonstrate resonance properties at frequencies of about 0.1 Hz. In an HR baroreflex closed-loop system, a shift in BP can cause a compensatory HR response that is delayed for approximately 5 seconds. These delays of approximately 5 seconds can in turn coincide with resonance oscillations of about 0.1 Hz (since oscillation periods are equal to twice the value of the delay—e.g., a cycle of about 10 seconds comprised of adjacent 5 second periods). Similarly, the VT baroreflex system in humans can demonstrate resonance properties at frequencies of about 0.03 Hz. In a VT baroreflex closed loop system, the compensatory response of the vasculature is delayed for approximately 10-20 seconds as compared to approximately 5 seconds in the HR baroreflex system. This delay of about 15 seconds coincides with resonance oscillations of about 0.03 Hz (since, again, oscillation periods are equal to twice the value of the delay, e.g., a cycle of about 30 seconds comprised of adjacent 15 second periods).
One mechanism to create or induce resonance in an HR baroreflex system has been through slow paced breathing at an average of about 6 full cycles per minute in which an individual inhales for approximately 4-7 seconds and exhales for approximately 4-7 seconds. Doing so results in individual inhalation-exhalation cycles of about 8-14 seconds. While rates vary according to the individual, breathing at such rates can produce high amplitude oscillations in the HR baroflex system that typically range between about 0.075 Hz and about 0.125 Hz, depending on short-term baroreflex sensitivity and short-term heart rate variability. Long-term practice of such breathing patterns has been linked to an increase in baroreflex sensitivity and HRV at rest. In other words, research has shown that it is possible to cause or induce resonance in the CVS through manipulation of breathing, auditory and visual stimuli, or rhythmical muscle relaxation.
One mechanism to induce resonance in the VT baroreflex system has also been through slow paced breathing at an average of approximately 2-3 full cycles per minute in which an individual inhales for approximately 10-20 seconds and exhales for approximately 10-20 seconds resulting in individual inhalation-exhalation cycles of 20-40 seconds. While rates vary according to the individual, breathing at such rates can produce high amplitude oscillations in the VT baroflex system of about 0.03 Hz, depending among other things on normalization in vascular tone and blood pressure regulation. Similar to the HR baroreflex system, some research has demonstrated that it is possible to cause resonance in the VT baroreflex system cardiovascular system through the manipulation of breathing.
Research directed specifically to the effects of breathing at approximately the foregoing rates has revealed significant potential effects on the CVS, with potential cascading effects on disorders associated with vagal and autonomic dysfunction. Some studies have revealed that paced breathing at a rate of approximately 0.1 Hz can be used effectively in heart rate variability (HRV) biofeedback techniques, as described by Lehrer and Vaschillo (2003). Some studies have also revealed that entraining the CVS and breathing at about 0.1 hz can improve the symptoms of numerous disorders, such as depression, PTSD, fibromyalgia, hypertension, abdominal pain, and coronary heart disease (Vaschillo et al., 2010; Wheat and Larkin, 2010; Zucker et al, 2009). As noted by Vaschillo and colleagues in 2010, “the therapeutic effects of HRV biofeedback are thought to be due to the induction of high-amplitude oscillations in HR, BP, and VT at specific frequencies which exercise and activate homeostatic reflexes (e.g., the baroreflex reflex), retrain them, and initiate, through the baroreceptors, a cascade of neurobiological events that produces a generalized inhibitory effect on the brain.”
Other methods to cause high-amplitude oscillation in HR, BP, and VT at specific frequencies may exist, including presenting emotional pictures at a ten second cycle (5 seconds with pictures, 5 seconds without pictures—see Vaschillo et al., 2010), and self-induced rhythmical muscle tension stimulation at the same frequency (France et al., 2006; Lehrer et al., 2009). External or patient-induced stimulation provided at specific frequencies thus may entrain similar frequencies in the CVS through increasing spectral power in the inter-beat interval (RRI), blood pressure (BP) and pulse transit time (PTT). External or patient-induced stimulation may also improve other areas of functioning such as increases in cerebral oxygenation (see, e.g., France, France, & Patterson, 2006). External stimulation through visual pictures or muscle tension exercises might also produce similar clinical effects in the CVS as those produced by breathing biofeedback techniques. Treating diseases associated with cardiovascular dysfunction using external stimulation techniques or patient-induced stimulation, such as hypertension, atrial fibrillation, mental health disorders, depression, post-traumatic stress disorder and substance abuse, may also be possible.
The average stimulation frequency of the HR-baroreflex system is approximately 0.1 Hz (or 6 cycles per minute). Individual differences in the optimal frequency to create resonance in the HR CVS exist, however, and can range between 4 and 7 cycles per minute. These differences have been noted to be a result of differences in blood volume, and can be roughly estimated using height and gender information. Taller individuals and males have longer stimulation rates (e.g. taller individuals have longer total cycles) to create HR resonance. The same is true for VT-baroreflex, where taller individuals require longer total stimulation cycles to create VT resonance.
In addition to creating increased oscillations at the above resonance frequencies which increase dramatically when stimulated, CVS functions may be entrained at other frequencies through breathing at higher or lower rates. Frequencies entrained in the CVS correspond roughly to a total period of one cycle of inhalation and exhalation combined, indicating that the CVS might be entrained using a range of active and/or inactive stimulation cycles. As described above, then, breathing and external stimulation through visual pictures or muscle tension exercises can produce changes in the CVS exhibited through high amplitude oscillations at frequencies that approximately mirror the frequency of breathing, for example.
It has been discovered by us, however, that external stimulation via rhythmical mechanical external vibration can also entrain the CVS to increase oscillations at resonance frequencies or other specific frequencies. This can have profound implications for the treatment of numerous psychiatric and medical disorders, particularly depression and cardiovascular disease, which are often associated with dysregulation in the cardiovascular system and decreased vagal tone. Previous methods to induce resonance or high amplitude oscillations often required active involvement from the patient (e.g., paced breathing or muscle tension). According to one embodiment, there is provided a passive means to stimulate the same reflexes, which can extend the therapeutic effects to a significantly larger population in need.
Resonance or high amplitude oscillations can be induced or created in the CVS by means of a system or device that creates and/or delivers vibration stimulation according to a vibration therapy stimulation regime, which according to some embodiments is predetermined or pre-programmed. Examples of such vibration regimes for the HR baroreflex system include an 8-14 second cycle (e.g., on for 4-7 seconds and off for 4-7 seconds, or increasing in vibration frequency for 4-7 seconds or decreasing in vibration frequency for 4-7 seconds), a 20-40 second cycle (e.g., 10-20 seconds active or increasing vibration frequency and 10-20 seconds inactive or decreasing vibration frequency). However, there is evidence that one can entrain the CVS at nearly any frequency within the human range to increase specific oscillations in the CVS.
Disclosed and described herein are techniques for entraining frequencies in the CVS to promote human adaptability and responsiveness to internal and environmental perturbations, as well as to promote overall health and wellbeing. Rhythmical mechanical external stimulation of the CVS at specific frequencies can be employed to powerfully impact the CVS. The high amplitude oscillation of cardiovascular functions at resonant frequencies generated by such stimulation can help regulate the CVS, modulate the vagus nerve and the brain, and normalize the inhibition-excitation balance of the CVS on brain systems, and in such a manner provide beneficial therapy to a patient. In some embodiments, the vibration stimulation cycle can entrain the CVS at a frequency or period that mirrors a combined on-off cycle or increasing/decreasing frequency vibration provided by the systems and devices described and disclosed herein.
As noted above, the HR system resonates at about 0.1 Hz and the VT system resonates at approximately 0.03 Hz, although variability between individuals exists necessitating a range of cycle options. In some embodiments, a system or device delivers repeated cycles of mechanical vibration to a patient that vary between 8-14 seconds (4-7 seconds active or increasing vibration frequency for a first period and 4-7 seconds inactive or decreasing vibration frequency for a second period) to stimulate the HR baroreflex system and produces cycles of vibration between 20-40 seconds (10-20 seconds active or increasing vibration frequency for a first period and 10-20 seconds inactive or decreasing vibration frequency for a second period) to stimulate the VT baroreflex system. According to some embodiments, the vibration method and therapy can entrain the CVS using total cycles (the first period and second period adjacent) that range between 8 seconds and 40 seconds. By way of example, a 10 second total cycle can create an increase in CVS oscillations at about 0.1 Hz, a 12 second total cycle can create an increase in CVS oscillations at about 0.08 Hz, a 20 second total cycle can create an increase in CVS oscillations at about 0.05 Hz, and a 40 second total cycle can create an increase in CVS oscillations at about 0.025 Hz. While the goal is to entrain individuals at their approximate resonant frequency (e.g., ˜1 Hz), the therapeutic stimulation described and disclosed herein can be used to approximate nearly any CVS frequency ranging between, by way of example, about 0.01 Hz and about 0.4 Hz in any one or more of the HR, BP and VT systems.
The amplitude and frequency of the actual vibration that is provided to the patient (as opposed to the time period or frequency of the overall cycle of the vibration that is provided) can be any suitable frequency or amplitude that is tolerable by the human body. The frequency of the actual vibration signal provided during a cycle can be stable (e.g., 100 Hz for 5 seconds, and then inactive for 5 seconds) or increasing and then decreasing, or decreasing and then increasing. For example, an increase in vibration frequency for 7 seconds (e.g., from 5 Hz to 30 Hz over 7 seconds) followed by a decrease in vibration frequency (e.g., from 30 Hz to 5 Hz over 7 seconds) during a 14 second cycle can be used to create a rhythmical repeating pattern of vibration and stimulation.
Referring now to FIG. 1, there is shown one embodiment of therapeutic vibration stimulation delivery system 100 comprising wristband 101 and vibration signal generator 108. As shown in FIG. 2, system 100 can be worn on a patient's wrist with vibration signal generator 108 facing inwardly and in contact with the patient's skin. Note that in some embodiments system 100 is configured to deliver the therapeutic vibration signal through a patient's clothing or one or more layers of clothing or material. In FIG. 1, system 100 is a standalone device such as an arm band with an on-off switch that provides vibration signals over a partial cycle 4-20 seconds long, followed by a partial cycle 4-20 seconds long where no or little vibration is provided, thereby entraining the CVS. Wearable band 101 can be an adjustable strap configured to fit multiple areas of the body and extremities (e.g., hands, feet, chest, arms, etc.), as well as multiple body types (e.g., thin, short, medium, tall, and large body types) so that a patient can obtain a good fit. Band 101 can be configured to house vibration signal generator 108, which can be powered by either a disposable or rechargeable battery 120 or other type of power source. According to one embodiment, a vibration motor is included in vibration signal generator 108, and can be charged from within band 101 or be removed therefrom for charging, repair or replacement. FIG. 3 shows one embodiment of such a vibration motor, as described in Product Data Sheet 304-005 of Precision Microdrives dated 2013 which is filed on even date herewith in an Information Disclosure Statement and the entirety of which is hereby incorporated by reference herein.
FIGS. 4 and 5 show further embodiments of wearable system 100. In FIG. 4, band 101 further comprises adjustable closure 103 which according to some embodiments may be configured to fit multiple areas of the body and/or extremities. In FIG. 5, filament 109 is disposed along the length or portions of the length of band 101, and is operably connected to signal generator 108 to permit enhanced or better-distributed vibration signals to the patient through band 101.

As further shown in FIG. 9, the frequency at which the actual vibration signal is provided to the patient begins at or near 0 Hz at 2 seconds, ramps up to or increases to about 50 Hz at or near 2 seconds, remains constant at about 50 Hz between 2 seconds and 3 seconds, and ramps down or decreases from about 50 Hz to about 0 Hz at 3 seconds. No vibration signal, or a lower amplitude vibration signal, is provided between 3 seconds and 17 seconds. The full 15-second cycle is then repeated beginning at 17 seconds after the inactive or low-amplitude period has come to an end. Successive cycles comprising the illustrated active and inactive or low-amplitude portions are repeated as long as desired to effect suitable entrainment of the CVS. Successive cycles can also be terminated, adjusted or modified in accordance with physiological parameters of the patient that have been sensed, more about which is said below.
In FIG. 10, there is shown a further embodiment of a method of providing therapeutic external mechanical vibration stimulations to a patient, where the overall period or cycle of stimulation is 15 seconds long (see, for example, 2 seconds to 17 seconds along the horizontal axis of FIG. 10), the active or “on” portion of the cycle is 1.75 seconds long (see, for example, 2 seconds to 3.75 seconds along the horizontal axis of FIG. 10), and the inactive, “off” or low-amplitude portion of the cycle is 13.5 seconds long (see, for example, 3.75 seconds to 17 seconds along the horizontal axis of FIG. 10). As further shown in FIG. 10, the frequency at which the actual vibration signal is provided to the patient begins at or near 0 Hz at 2 seconds, ramps up to or increases to about 50 Hz at or near 2.75 seconds, and then at 2.75 seconds ramps down or decreases from about 50 Hz to about 0 Hz at 3.75 seconds. No vibration signal, or a lower amplitude vibration signal, is provided between 3.75 seconds and 17 seconds. The full 15-second cycle is then repeated beginning at 17 seconds after the inactive or low-amplitude period has come to an end. Successive cycles comprising the illustrated active and inactive or low-amplitude portions are repeated as long as desired to effect suitable entrainment of the CVS. Successive cycles can also be terminated, adjusted or modified in accordance with physiological parameters of the patient that have been sensed, more about which is said below.
FIGS. 6 through 10 illustrate five different embodiments of methods of providing vibration stimulation therapy to a patient, where each of the illustrated methods comprises delivering at least one vibration signal to at least one location on the patient's skin, or through clothing or a layer disposed next to the patient's skin. As shown in FIGS. 6 through 10, the vibration signal is successively delivered to the patient over first periods of time and not delivered, or delivered at low amplitudes, to the patient over second periods of time. The second periods of time are interposed between the first periods of time, and the vibration signal, and the first and second periods of time, are together configured to trigger or induce resonance or high amplitude oscillations in a cardiovascular system of the patient.
FIG. 11 shows one embodiment of a method 500 for providing therapeutic stimulation to a patient that is consistent with the stimulation patterns illustrated in FIGS. 6 through 10. The method begins at step 501, and proceeds to step 503 where a therapeutic vibration signal is delivered to a patient over a first period of time. Following the first period of time, at step 505 a therapeutic vibration signal is not delivered to the patient over a second period of time. Steps 503 and 505 are repeated via loop 507 as desired, or as required or necessary.
The induced resonance or oscillations are characterized by a third period that approximates the adjacent first and second periods combined, and that represents the above-described overall periods or total cycles. For example, a third period of 12 seconds (e.g. 6 seconds vibration “on” and 6 seconds vibration “off”) will entrain the CVS to oscillate at higher amplitudes at approximately 0.08 Hz than would be without the stimulation. This is analogous to breathing in for 6 seconds and out for 6 seconds creating a 12 second period to entrain the CVS at approximately 0.08 Hz. By way of example, such a third period can range between about 4 seconds and 200 seconds, between about 4 and 60 seconds, between about 8 seconds and 40 seconds, between about 4 seconds and 20 seconds, and/or between about 8 seconds and about 14 seconds. Other ranges are contemplated for the third period.
Likewise, various ranges of time are contemplated for the first and second periods of time, which are not intended to be limited by the explicit examples provided herein. For example, the first and/or second periods of time may range between about 0.25 seconds and 100 seconds, between about 0.5 seconds and 100 seconds, between about 1 second and 100 seconds, between about 2 seconds and about 100 seconds, between about 2 seconds and about 30 seconds, between about 4 seconds and about 20 seconds, between about 4 seconds and about 10 seconds, between about 4 seconds and about 7 seconds, or any other suitable range of time. Other ranges are contemplated for the first and second periods.
Also by way of example, the frequency of the vibration signal can range between about 0 or 0.1 Hz and about 2,000 Hz, between about 0, 0.1 or 1 Hz and about 250 Hz, between about 5 or 10 Hz and about 125 Hz, between about 25 Hz and about 125 Hz. Other ranges of frequencies are also contemplated.
Continuing to refer to FIGS. 6 through 10, the first periods of time are shown as being adjacent to the second periods of time. According to some embodiments, other or further periods of time may be interposed between the first and second periods of time. The amplitude of the vibration signal may also be held is approximately constant over at least major portions of the first and/or second periods of time. As further shown in FIGS. 6 through 10, the frequency of the vibration signal may be varied over the first periods of time. For example, the frequency of the vibration signal may increase near the beginning of the first period of time and decrease near the end of the first period of time, and the first periods of time can be configured to correspond to an “on” mode while the vibration signal is being delivered to the patient, and the second periods of time can be configured to correspond to an “off” mode while the vibration signal is not being delivered to the patient.
Furthermore, and continuing to refer to FIGS. 6 through 10, the method can additionally comprise sensing a physiological parameter of the patient and, in response to such sensing, adjusting at least one of the frequency, amplitude or phase of the vibration signal, and/or adjusting at least one of the first and second periods of time over the which the vibration signal is being provided or is not being provided to the patient. For example, the method can additionally comprise sensing a physiological parameter of the patient and, in response to such sensing, changing the length of at least one of the first period and the second period, terminating delivery of the vibration signal to the patient, and initiating delivery of the vibration signal to the patient.
The resonance or high amplitude oscillations induced or created by the methods described and disclosed herein may be used to treat a patient for a stress-related disorder, depression, hypertension, an autonomic dysfunction, atrial fibrillation, coronary heart disease, diabetes, post-traumatic stress disorder, substance abuse, and yet other disorders, maladies or diseases. Such induced or created resonance, or forced oscillations, can also be employed to increase a patient's baroreflexes, increase the flexibility of a patient's CVS, and/or increase or improve a patient's vagal nerve tone and/or stress reactivity.
In FIG. 12, there is shown yet another embodiment of a method of providing therapeutic external mechanical vibration stimulation to a patient, where the overall third period or cycle of stimulation is 10 seconds long (see, for example, 9.5 seconds to 19.5 seconds along the horizontal axis of FIG. 12), a first portion of the cycle is about 5 seconds long (see, for example, approximately 9.5 seconds to 14.5 seconds along the horizontal axis of FIG. 12), and a second portion of the cycle is about 5 seconds long (see, for example, approximately 14.5 seconds to 19.5 seconds along the horizontal axis of FIG. 12). As further shown in FIG. 12, the frequency at which the actual vibration signal is provided to the patient during the first portion of the cycle is at about 5 Hz at about 9.5 seconds, ramps up to 100 Hz at 14.5 seconds, is stable between 14.5 and 15.5 seconds, and then ramps down from 100 Hz to 5 Hz between 15.5 and 19.5 seconds. In this embodiment, the lowest vibration frequency vibration is about 5 Hz. The full 10 second cycle is then repeated beginning at about 19.5 seconds. As shown, the full cycle of 10 seconds can include stable, increasing or decreasing frequencies within each cycle. Successive cycles comprising the illustrated first and second periods are repeated as long as desired to effect suitable entrainment of the CVS. Successive cycles can also be terminated, adjusted or modified in accordance with physiological parameters of the patient that have been sensed, more about which is said below.
In FIG. 13, there is shown a further embodiment of a method of providing therapeutic external mechanical vibration stimulation to a patient, where the overall period or cycle of stimulation is 11 seconds long (see, for example, 1 second to 12 seconds along the horizontal axis of FIG. 13), first slowly-ramping portions of the cycle are each 1 second long (see, for example, 1 second to 2 seconds, and 11 seconds to 12 seconds, along the horizontal axis of FIG. 13), and second more quickly ramping portions of the cycle are 6 seconds long (see, for example, 2 seconds to 8 seconds along the horizontal axis of FIGS. 10, and 8 seconds to 11 seconds along the horizontal axis of FIG. 13). As further shown in FIG. 10, the frequency at which the actual vibration signal is provided to the patient during the first portions of the cycle range between about 5 Hz and about 10 Hz, and then ramp up to 100 Hz at or near 8 seconds, and then ramp down to 10 Hz at or near 11 seconds. As shown in FIG. 13, the frequency of the provided vibration signal varies throughout the cycle. The full 11 second cycle is then repeated beginning at 12 seconds after the last first portion of the cycle has been completed.
Successive cycles comprising the illustrated first and second portions may then be repeated as long as desired to effect suitable entrainment of the CVS. Successive cycles can also be terminated, adjusted or modified in accordance with physiological parameters of the patient that have been sensed, more about which is said below.
FIGS. 12 and 13 illustrate two embodiments of methods of providing vibration stimulation therapy to a patient, where each of the illustrated methods comprises delivering first and second vibration signals to at least one location on the patient's skin, or through clothing or a layer disposed next to the patient's skin, the first and second vibration signals corresponding to first and second vibration modes, respectively. As shown in FIGS. 12 and 13, the first vibration mode and first vibration signal correspond to first periods of time, while the second vibration mode and second vibration signal correspond to second periods of time. As further shown in FIGS. 12 and 13, the second periods of time are interposed between the first periods of time, and the first vibration signal is different from the second vibration signal. The first and second vibration signals, first and second vibration modes, and first and second periods of time are together configured to trigger or induce resonance or high amplitude oscillations in a cardiovascular system of the patient.
FIG. 14 shows one embodiment of a method 600 for providing therapeutic stimulation to a patient that is consistent with the stimulation patterns illustrated in FIGS. 12 and 13. The method begins at step 601, and proceeds to step 603 where a first therapeutic vibration signal is delivered to a patient over a first period of time. Following the first period of time, at step 605 a second therapeutic vibration signal is delivered to the patient over a second period of time. Steps 603 and 605 are repeated via loop 607 as desired, or as required or necessary.
According to some embodiments, and continuing to refer to FIGS. 12 and 13, the induced resonance or oscillations are characterized by a third period that approximates the adjacent first and second periods combined, and that represents the above-described overall periods or cycles. For example, a third period of 40 seconds (e.g., 20 seconds with vibration “increasing” and 20 seconds with vibration “decreasing”) will entrain the CVS to oscillate at higher amplitudes of approximately 0.025 Hz than would be the case without such stimulation. By way of example, such a third period can range between about 4 seconds and 200 seconds, between about 4 and 60 seconds, between about 8 seconds and 40 seconds, between about 4 seconds and 20 seconds, and/or between about 8 seconds and about 14 seconds. Other ranges are contemplated for the third period.
Likewise, various ranges of time are contemplated for the first and second periods of time illustrated in FIGS. 12 and 13, which are not intended to be limited by the explicit examples provided herein. For example, the first and/or second periods of time may range between about 0.25 seconds and 100 seconds, between about 0.5 seconds and 100 seconds, between about 1 second and 100 seconds, between about 1 second and about 100 seconds, between about 2 seconds and about 30 seconds, between about 4 seconds and about 20 seconds, between about 4 seconds and about 15 seconds, between about 4 seconds and about 10 seconds, between about 2 seconds and about 30 seconds, between about 3 seconds and about 20 seconds, or any other suitable range of time. Also by way of example, the frequency of the vibration signals shown in FIGS. 9 and 10 can range between about 0 or 0.1 Hz and about 2,000 Hz, between about 0, 0.1 or 1 Hz and about 250 Hz, between about 1 Hz and about 200 Hz, between about 5 Hz or about 10 Hz and about 125 Hz, and between about 25 Hz and about 125 Hz.
Continuing to refer to FIGS. 12 and 13, the first periods of time are shown as being adjacent to the second periods of time. According to some embodiments, other or further periods of time may be interposed between the first and second periods of time. The amplitude of the vibration signal may also be held is approximately constant over at least major portions of the first and/or second periods of time. As further shown in FIGS. 12 and 13, the frequency of the vibration signal may be varied over either the first period of time, the second period of time, or both of the first and second periods of time. For example, and as illustrated in FIGS. 12 and 13, the frequency of the vibration signal may increase near the beginning of the first period of time and decrease near the end of the first period of time, and the first periods of time can be configured to correspond to an “on” mode while the vibration signal is being delivered to the patient, and the second periods of time can be configured to correspond to a lower frequency or different frequency regime.
Furthermore, and continuing to refer to FIGS. 12 and 13, the method can additionally comprise sensing a physiological parameter of the patient and, in response to such sensing, adjusting at least one of the frequency, amplitude or phase of the vibration signal, and/or adjusting at least one of the first and second periods of time over the which the vibration signal is being provided or is not being provided to the patient. For example, the method can additionally comprise sensing a physiological parameter of the patient and, in response to such sensing, changing the length of at least one of the first period and the second period, terminating delivery of the vibration signal to the patient, and initiating delivery of the vibration signal to the patient.
As with respect to the methods illustrated in FIGS. 6 through 10, the resonance or high amplitude oscillations induced or created by the methods illustrated in FIGS. 12 and 13 may be used to treat a patient for a stress-related disorder, depression, hypertension, an autonomic dysfunction, atrial fibrillation, coronary heart disease, diabetes, post-traumatic stress disorder, substance abuse, and yet other disorders, maladies or diseases. Such induced or created resonance or oscillations can also be employed to increase a patient's baroreflexes, increase the flexibility of a patient's CVS, and/or increase or improve a patient's vagal nerve tone and/or stress reactivity.
Referring now to FIGS. 6 through 14, it is to be noted that ratios of the first period and the second period may be varied in any suitable manner, or may be fixed in any suitable manner. For example, the on-off stimulation ratios shown in FIGS. 6 through 10, or the increasing/decreasing ratios of FIGS. 12 and 13, can vary between or within each total cycle. According to one embodiment, for example, a 10 second cycle can comprise active stable or increasing vibration frequencies over 5 seconds, and inactive or decreasing frequencies over 5 seconds resulting in a 1:1 ratio of the first and second periods. Other ratios are contemplated. Those skilled in the art will now, after having read and understood the specification and drawings of the present patent application, that virtually infinite number of permutations, combinations, and modifications may be made the vibration stimulation regimes described and disclosed herein, and to the periods, frequencies, amplitudes, phases, waveform morphologies, and other characteristics of the delivered vibration signals while providing efficacious treatment to a patient.
We turn now to FIGS. 15 through 18, where there are illustrated the results of testing on a patient one embodiment of the methods, systems and devices described herein. FIG. 15 shows cardiac power spectrum density (“PSD”) consecutive R-wave to R-wave interval (“RRI”) data acquired from a seated 47-year-old test subject while no therapeutic vibration stimulation therapy was being delivered to the test subject (“no vibrations provided”). FIG. 16 shows cardiac PSD RRI data acquired from the same test subject while therapeutic vibration stimulation therapy was being delivered to the test subject (“vibrations provided”).
The vibration stimulation provided to the test subject while the data of FIG. 16 were being acquired comprised six-second first periods of time, where active external vibration signals increasing in frequency were provided to the test subject followed by six-second second periods of time where active external vibration signals decreasing in frequency were provided to the test subject, thus resulting in 12 second combined or third periods of time. The baseline period employed was 5 minutes of no stimulation (FIG. 15). The vibration intervention period of continuous 12 second cycles lasted 5 minutes (FIG. 16). A 12-second cycle was selected specifically to highlight that the system disclosed and described herein is capable of shifting oscillations in the CVS to a different frequency and increase high amplitude oscillations at that frequency.
Once the subject was seated, and before monitoring or vibration signals were provided, various sensors were connected to the test subject, including cardiac heart rate and blood pressure sensors so that in addition to RRI, heart rate variability (“HRV” or beat-to-beat heart rate) and blood pressure variability (“BPV” or beat-to-beat blood pressure) could be measured. When the vibration signals were provided to the subject, the vibration signals were increased in frequency from approximately 5 Hz to 30 Hz over the first period of 6 seconds, and during the second period of 6 seconds were decreased in frequency from 30 Hz to 5 Hz (FIG. 16), and the process repeated successively over a 5-minute period of time. During periods of no stimulation (FIG. 15), no vibration signals were provided to the patient.
During the experiments, a computer based microcontroller (ARDUINO) was used to send an intermittent PWM (pulse width modulation) signal to a vibration motor, which was operated at 1.5 volts with 4.6 mm of displacement and an acceleration of 0.5 Gs. This allowed the intensity as well as the frequency of vibration pulses to be controlled by changing the electrical current provided to the motor.
Comparison of FIGS. 15 and 16 shows that the vibrations provided to the test subject resulted in forced high amplitude oscillations and entrainment of the subject's CVS at approximately 0.08 Hz. Comparison of FIG. 15 to FIG. 16 shows that RRI PSD amplitude at 0.078 Hz increased from 12,161 ms2/Hz in FIGS. 13 to 18,557 ms2/Hz when the vibration signal generator was placed around the subject's wrist, and to 20,750 ms2/Hz when placed on subject's neck, which indicates that vibration stimulation indeed entrained the HR rhythms of the subject's CVS. Continuing to refer to FIGS. 13 and 14, decreased peaks in other frequencies resulted in a smoothed wave form with distinct peaks at approximately the same period as the stimulation frequency.
FIGS. 17 and 18 show results obtained from the same test subject when mean arterial pressure (“MAP”) was measured without vibration signals being provided to the subject (FIG. 17), and with the same vibration signals being provided to the subject (FIG. 18) as described above with respect to FIG. 16. FIGS. 17 and 18 show that MAP PSD amplitude at 0.078 Hz increased from 88.8 ms2/Hz to 215 ms2/Hz when the vibration signal generator was placed around the wrist of the subject, and to 259 ms2/Hz when the vibration signal generator was placed on the neck of the subject, which indicates that vibration stimulation did indeed entrain the blood pressure rhythms of the subject's CVS. Decreased peaks in other frequencies resulted in a smoothed waveform with distinct peaks, as shown in FIG. 18.
