In many medical fields the recovery of muscular activity or its improvement up to the level of the optimal parameters is required. Apart from the classical solution for rehabilitation (physical exercises) the use of electrical stimulation has become quite frequent of late. The paper presents an interface that detects the electromyographic (EMG) activity, assesses it, and generates appropriate electrical stimuli, by means of a specific type of fuzzy control system, in order to control the dynamics of the EMG. The proposed interface will detect the motion and muscular activity, it will evaluate and generate the electrical stimulus using a fuzzy system tuned by dynamic of motion. The application will transmit e-Health information to the physician via Internet, synthetic, at request using TCP/IP stack and SMS services for wireless communication.
