Abstract: An exercise training system for prompting a user for stereo typed exercise and recording the intensity of the exercise, the training system consisting of an electromyographic sensor member which produces a rectified and time averaged signal forming a muscle force signal, the sensor member being provided with at least one electrode that is positioned adjacent to the user's muscle group for indicating muscle force of that muscle group, and a control member having a clock for measuring time intervals, and an alerting member for alerting the user that an exercise period has started as determined by the clock for a predetermined time interval loaded into the control means, whereby the user in response to the alerting member contracts and relaxes a predetermined muscle group and the muscle force used in the exercise is sensed by the electromyographic sensor.

Abstract: Excitation of the skeletal musculature of a subject is measured by an electromyogram (EMG), processed and applied to control application to the musculature of electrical muscle stimulation (EMS) signals proportional to the electrical nerve impulses. The invention is useful for re-education and/or amplification of muscular control where motor control has suffered impairment.
