System for assessing neuromuscular function using synchronized physiological and movement signals

Abstract

A system for assessing neuromuscular function using synchronized physiological and movement signals, the system comprising: a memory configured to store executable instructions, synchronized physiological measurements, synchronized movement measurements, calibration information, synchronization information, subject assessment information, and neuromuscular assessment information; one or more physiological sensor units positioned relative to a subject and configured to detect physiological signals representative of electrical muscle activity, cardiac activity, respiratory characteristics, skin response, body temperature, pressure distribution, force generation, or blood circulation;one or more motion sensors configured to detect motion signals representative of body position, limb orientation, joint displacement, body acceleration, angular movement, posture, balance, gait characteristics, and trajectory; a synchronization controller electrically coupled to the physiological sensor units and the motion sensor units and configured to distribute a common time reference to the physiological sensor units and the motion sensor units, generate synchronized timestamps corresponding to individual physiological and motion measurements, compensate for sampling latency and communication delay in the acquisition of the physiological and motion signals, and generate synchronized acquisition frames corresponding to the common observation intervals;a signal processing unit that is electrically connected to the physiological sensor units and is configured to amplify, filter, stabilize, digitize, normalize and calibrate the physiological signals prior to synchronization;one or more processors that communicate with memory and are configured to retrieve the synchronized acquisition frames, create synchronized physiological motion records by linking temporally corresponding physiological samples with motion samples using the synchronized timestamps, determine signal quality information corresponding to each synchronized physiological motion record, reconstruct synchronized evaluation frames containing physiological activity information, motion information, temporal reference information, and sensor status information, and store the reconstructed synchronized evaluation frames in memory;a neuromuscular assessment processor that communicates with one or more processors and is configured to determine muscle activation timing, muscle recruitment sequence, bilateral muscle symmetry, joint coordination features, movement consistency, reaction latency, postural stability, balance features, fatigue progression, recovery features, and functional movement performance by correlating physiological activity information with movement information in the reconstructed synchronized assessment frames; a visualization interface configured to simultaneously display synchronized physiological waveforms, synchronized movement representations, neuromuscular assessment parameters, and assessment history according to the reconstructed synchronized assessment frames;and a communication interface configured to transmit the reconstructed synchronized assessment frames and the generated neuromuscular assessment information to one or more external computer devices for storage or further analysis.
