System and method for muscle engagement identification

A system for development of a limb muscle, comprising:

• a contraction sensor for detecting a limb muscle contraction;
• an elastic bumper to couple the contraction sensor wherein the elastic bumper is placed against the limb muscle;
• a belt holding the contraction sensor and the elastic bumper over the limb muscle;
• a movement sensor for detecting body movements;
• a processor coupled to the contraction sensor for receiving limb muscle contraction signals from the sensor and body movement signals from the movement sensor wherein the processor determines limb muscle engagement values that are between zero and a 100% maximum engagement value from the muscle contraction signals based upon the limb muscle contraction signal;
• and
• a display coupled to the processor wherein the display displays limb muscle engagement value and body movement data simultaneously.
