Abstract
A system to monitor surface electromyographic (EMG) activity of a user and provide appropriate feedback to the user includes an EMG feedback monitor sized and configured to be worn by the user. In the depicted embodiment, surface EMG activity is measured with electrodes integrally affixed to a housing of the system. Feedback is typically provided using vibrations of certain duration and repetition. The system operates under various user selectable operational modes. Each operational mode is associated with particular electromyographic feedback criteria used to determine appropriate feedback for the user. The electromyographic feedback criteria is related to signal levels and time measurements associated with surface EMG activity level measured of the user. The depicted embodiment includes a computer interface allowing EMG signal data recorded by the EMG feedback monitor to be sent to a computer system. The computer system is also used to adjust and download desired operational modes into the EMG feedback monitor.
