Microprocessor controlled system for unsupervised EMG feedback and exercise training
First Claim
1. A neuromuscular training system for alerting a user when a training session is to begin and recording the performance of the session, the training system comprisingan electromyographic sensor which produces an electrical signal representative of EMG activity,the sensor being provided with at least one electrode that is positioned adjacent to a muscle group of the user for indicating muscle force of that muscle group and wherein the at least one electrode is secured about a member which is adapted and constructed to be inserted into a natural orifice of the user for measuring the muscle force,an amplifier connected to the sensor for receiving the electrical signal representative of EMG activity and amplifies the electrical signal to provide an amplified output,a filter that receives the amplified output of the amplifier and provides a filtered output,a sensitivity control that receives the filtered output and provides a sensitivity controlled output.a processing network that receives the sensitivity controlled output and provides a signal conditioned output,an analog-to-digital converter that receives the signal conditioned output and converts the signal conditioned output to a digital output,a microprocessor that receives the digital output and provides a processed output,a control means having a clock for measuring time intervals and that receives the processed output 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 and an alerting means for generating a tone, as modulated by the microprocessor, that provides an audio feedback signal, anda display means that receives the processed output for displaying the level of muscle ennervation exerted by the user and generated in the exercise period when contracting a muscle group adjacent to the electrode of the electromyographic sensor,the display means and the alerting means being also provided with a speaker for communicating the audio feedback signal to the user,whereby the user in response to the alerting means contracts and relaxes the muscle group and the level of muscle ennervation is sensed by the electromyographic sensor.

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.
