Description of the Related Art
Numerous neuromuscular problems and disorders affect the ability of the brain to transmit the appropriate signals to the muscles. Injury, stroke, Parkinson's, Huntington's, Tourette syndrome, drugs, and even fatigue are but a few examples. Tremors are involuntary muscle contractions that oscillate in frequency. Hypokinesia is a hesitation or decrease in muscle movement usually associated with damage to the basal ganglia. Hyperkinesia is an increase in muscle movements that results in excessive normal or abnormal movements. Such movements are variously described as dystonia, chorea, athetosis, myoclonus, tremors and tics. Measurements of neuromuscular movement are often very subjective and rarely done with the accuracy required for creating large consistent databases. This is especially true for comparison of random muscle movements and aberrant muscle movements occurring during conscious activities such as eating and trying to use a cell phone. Good measurement instrumentation is usually found at sites that require the patient to travel some distance to be properly tested. Other devices are expensive and may require a doctor's recommendation.
However, many modern devices, such as smartphones, already incorporate a computer linked to a highly accurate clock, an accelerometer and a gyroscope. These parts are all necessary to measure muscle movements, but currently cannot be used for measuring neuromuscular actions diagnostically without being associated with a means to standardize and store repeated movements over time, over distances, and between normal and abnormal conditions.
Additionally, many modern devices, such as smartphones, incorporate wireless communication capabilities that enable the digital storage of vast amounts of data secondary to the device. For example, data from a modern device may be stored wirelessly in “cloud” storage (e.g. “the cloud”). Once neuromuscular actions can be recorded and transmitted in a consistent and reproducible way, and then the necessary databases can be established to develop diagnostic algorithms discriminating various neuromuscular conditions.
There are currently no devices available that enable neuromuscular movement measurement, data processing, transmission, storage, and large database analysis during conscious directed activities such as drawing a standard figure eight. There are currently no devices or applications available that enable the inexpensive and wide spread use for monitoring and prognosticating neuromuscular variations associated with the measurement of functional performance relative to target patterns.
U.S. Pat. No. 8,679,038 to Giuffrida discloses a movement disorder monitor that is worn continuously to provide continuous information to measure the severity of a subject's movement disorder. See also, for example, U.S. Patent Application Publication No. 2015/0073310 to Pracar. What is needed is a device and system that need not be used continuously, but can provide vast amount of data over time, to diagnose a neuromuscular variations.
U.S. Pat. No. 7,312,863 discloses a motion-compensating light-emitting apparatus wherein a light-emitting apparatus, for enabling a spot of light to be projected on a desired target located a distance away such that the spot is projectable on the desired target without any or substantially any undesired movement. What is needed is a device and system that detects movement, but does not compensate for it, but rather, stores and/or analyzes the data illustrating the undesired movement for determining neuromuscular variation while using the light-emitting apparatus to trace a predetermined pattern.
Additionally, smartphones, such as the IPHONE® have been used, in general, for the quantification of Parkinson's disease hand tremor wherein the IPHONE® was mounted in a glove worn by the patient. See, for example, Robert LeMoyne, “Wearable and wireless accelerometer systems for monitoring Parkinson's disease patients—A perspective review”, SciRes, Vol. 2, No. 4, 113-115 (2013). What is further needed is a convenient, inexpensive and consistent device for measuring neuromuscular actions, not merely while wearing a sensor, but rather, relative to one or more easily available standardized patterns traced by the user and a system for permitting analysis of the results over time.
It is accordingly an object of the invention to provide a device, system and method to standardize, measure, and analyze the neuromuscular interactions and activity that occurs when a subject is required to trace a prescribed target pathway. According to one embodiment, a convenient, inexpensive, consistent and reproducible measurement of neuromuscular actions over time is obtained using a pointing device interfaced with new or existing technology having highly accurate clock(s), gyroscope(s), and/or accelerometer(s) to permit tracing of an easily available standardized pattern or set of patterns. The measurement data obtained from such devices during the performance of pattern tracing is then used to determine variations in neuromuscular control.
In one embodiment, a computing device capable of measuring three dimensional movements along the x, y and z axes, acceleration and time is coordinated with a pointing device. The computing device of the present embodiment includes computer processing, memory storage and wireless data transmission capabilities, can perform highly accurate time measurements, and incorporates at least one of a gyroscope, gravimeter and/or an accelerometer. The device can additionally be interconnected with a communications network, such as the Internet, and cloud storage. One particular device that can be used as the computing device of the present embodiment is a smartphone. The computing device is programmed by software stored in memory of the computing device and executed by a processor of the computing device, to measure, analyze, store and transmit the movement, acceleration and time detected and/or calculated by the computing device while the subject traces a prescribed target. In one embodiment, the target is constructed and selected based on the analysis of data and information obtained in the system during the performance on like targets by normal individuals and patients with neuromuscular abnormalities. Targets are optimized based on optimal differentiation of normal individual and patient performances.
In one embodiment of the invention, an integrated device detects and stores, in digital form, the muscle movements that occur when the operator of the device traces a defined figure using the pointing device. The movement data is stored in a system database, which is used to perform algorithmic analysis for the purpose of patient monitoring and diagnostics. Movement disorders associated with neuromuscular communication can be determined using the stored data, and any progression and/or change analyzed over time.
The use of this invention with prescribed targets enables the widespread storage and analysis of subject data via the Internet and cloud-based storage. Additionally, cloud-based storage permits the performance of general and algorithmic analyses necessary for prognostication of neuromuscular movement changes associated with disease, injury, chemical and fatigue effects.
In one embodiment of this invention neuromuscular cognitive activity can be analyzed in a gaming mode associated with the target tracing of mazes or problem solving tracings.
In another embodiment of the invention optimal neuromuscular cognitive activity in association with algorithmic analysis is used for mind body training and gaming rather than diagnostically.
Although the invention is illustrated and described herein as an integrated device to measure variations in neuromuscular control when tracing defined target patterns, and a system and method of using the integrated device, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.

Such a computing device 112 advantageously includes circuitry and sensors that can detect changes in the x, y, z directions (i.e., a gyroscope 162), acceleration (i.e., accelerometer 164), and time (i.e., clock 166) during the tracing of a specified target pattern 120. In particular, the system 100 embodies the ability to utilize readily available devices that incorporate accelerometers, gyroscopes and highly accurate timing. Note that the exemplary use of the gyroscope 162, accelerometer 164 and clock 166 is not meant to limit the invention only to these devices. Rather, the device 112 could instead, or in addition to, use other motion sensing, position sensing and/or timing devices, such as, gravitometers, magnetometers, resistance bend sensors, GPS (global positioning system), multilateration of radio signals from towers, laser positioning or radar positioning for the measurement of movement when performing a standardized task using a pointing device, without departing from the scope and spirit of the present invention.
Movement data collected by the device 112 can be stored, digitally, and used to calculate comparisons and measure changes in the performance of neuromuscular performance for individual subjects 115 over time. The stored data of subjects can be compared with normal patterns and results, and also, with patterns known to be associated with neurological, muscular and functional abnormalities. In one particular embodiment of the invention, the results data can be generated, analyzed and stored locally to the user 115, at the user's location 130 and/or in non-transitory memory of the computing device 112. Alternately, or in addition to such local storage, the results data can be communicated from the computing device 112 to a remote location 150, via one or more communications networks 140, for analysis by a remote server 152 and/or storage in one or more remote databases 154.
In one particular embodiment of the invention, data from multiple individuals 115 are transmitted to one or more remote databases in order to accumulate and store a large database of subject performance that is comparable and analyzable via the performance of the standardization of the pointing task. In this embodiment, the database is constructed via the Internet cloud storage transmission of movement data, which in turn enables the comparison of normal and other than normal performances in order to develop processing algorithms that are utilized for characterization of movement patterns with defined neuromuscular conditions. Diagnostic reliability emerges from the analysis of the large database made available via the use of this readily affordable and available device 110 in a system 100.
The basic device 110 may be described, in its most simple and general form, as a laser pointer or other narrow-beamed light pointing device 114 attached to a smartphone 112 programmed with a specialized application for collecting, storing, analyzing and/or communicating position and timing data. In one embodiment, the device 110 communicates data collected by the device 110 to a cloud server 152 and/or remote database 154 over a communications network 140, such as the Internet. For example, the device 112 records the detected x, y, z movements and acceleration of the device 112 over time when a subject traces a selected

Data collected by the device 110 can be analyzed locally and/or transmitted (by the communications device 163 and one or more communications networks 140) to a remote location 150 for remote storage and analysis of individualized data, instantaneously and/or over time. For example, data relating to muscle or other movement and acceleration in the three dimensional (x, y, z) axis over time for a subject 115 tracing a predetermined

In one particular embodiment of the invention, if desired, the device 110 is attached to a hand, arm or wrist of a user 115 using one or more of: elastic, hook and loop fasteners, a band, etc., so that a user is able to isolate separate muscle groups when tracing said figure. Additionally, in one embodiment, the pointing device 114 is attached to the computing device 112 with at least one of: (a) a plastic, metal or cloth case that holds the device 112 and incorporates a section of the case which allows the insertion or attachment of a laser pointer 114; (b) a holder or clip for a laser pointer 114 that can be attached to a device 112 via an elastic, mechanical spring, hook and loop fastener, such as VELCRO®, or adhesive interaction; (c) a glove in which the device 112 and pointing device 114 can be attached or inserted or (d) a pistol type grip into which the device 112 and pointing device 114 are attached or inserted.

For example,
Additionally, the patterns 120, 125 illustrated in
A pattern or set of patterns are provided to the user 115 for use in the system 100. As discussed above,
Referring to
A particular pattern 120 or 125 is selected, either by the subject or, in one embodiment, through guidance from a software application (“app”) executing on the computing device 112 and displayed on a wall or screen visible to the subject 115. For example, the type of pattern to be traced or used (i.e., spot, line, circle, or plain or complex figure) is input into the computing device, preferably by selection from a menu of the app or using image capture with a camera of the computing device. Alternately, the type of pattern can be determined by the app executing on the computing device 112 by comparison with stored movement patterns associated with the standardized patterns. Prior to the initiation of testing, the subject 115 is instructed to stand or sit a predefined distance from the pattern 120, 125 for the entire testing. The integrated device 110 is pointed towards the target 120, 125 by the user 115, in order to perform an exercise which can be measured and evaluated.
Testing is initiated and monitored by the software app executing on the computing device 112. In one embodiment, the recording, processing and storage of x, y, z movement, accelerations, and time is initiated in the computing device 112 by an audible timing alarm, such as a buzzer, or by an audible command or tone such as saying the word “start”. Alternately, if desired, the recording, processing and storage of x, y, z movement, accelerations, and time can be initiated in the computing device 112 by a specific set of x, y, z and acceleration movements, such as by shaking the device up and down. In another embodiment, the recording, processing and storage of x, y, z movement, accelerations, and time is initiated in the computing device 112 by another device, such as a button wirelessly connected to the computing device 112 via a wireless protocol, such as Bluetooth®. Other ways of starting the test may be used, however. For example, the app executing on the computing device 112, once started, can provide instructions to a user 115 on the display 165 of the computing device 112 or, more preferably, can provide spoken instructions to the user 115 to walk the user through the testing process.
During use, the subject 115 moves their hand 115a to aim and point the integrated device 110 towards a target 120, 125, so that the beam of light 114b projects onto the target 120, 125. The user 115 then, as instructed, will move the integrated device 110 and projected beam of light 114b relative to the target 120, 125. As an example, the user 115 will trace the projected beam of light 114b having a beam end 116, against the target 125 or through the interlinear spaces of a maze 120, so that movements by the user 115 can be calculated against a known and predicted movement, to detect variations of the user's movements. For example, if the subject 115 is tracing the triangle pattern 125 illustrated in

Thus, the present invention utilizes an integrated device that detects and stores, in digital form, the muscle movements that occur when the operator traces a defined figure using a pointing device such as a laser beam. The movement data is stored and then used to create the data base necessary to enable algorithmic analysis for the purpose of monitoring and diagnostics. Movement disorders associated with neuromuscular communication can be determined and progression and change analyzed over time in association with the stored data. A system and method for using the device are additionally provided. The present invention provides the capability for an inexpensive (because the user 115 may already own a smartphone or other intelligent device) and widespread measurement, analysis, transmission and storage of neuromuscular activity associated with performing a standardized task.
