An architecture for adaptive functional electrical stimulation for hemiplegic lower limb activities

Due to the advanced control methods and quickly developing computer technology, using functional electrical stimulation (FES) to restore functions to paralyzed extremities has attracted increasing attention. FES system utilizes the EMG of the upper body to control the stimulation to lower limb, as well as the muscle fatigue measure. In out architecture, EMG signals are used both to analyze the human intention, and to adapt the stimulation pattern as the feedback means. EMG signals provide one an access to physiological processes that cause the muscle to generate force, produce movement and accomplish the countless functions that allow one to interact with world around us. This paper explains the framework of the architecture and the experimental detail of EMG transformer part.
