Cross-correlation of electromyographic (EMG) signals from consecutive arm movements

Functional electrical stimulation (FES) has been used in several recent studies to help hemiplegics regain control of limb movement. The EMG (electromyographic) patterns associated with the movement of the unafflicted limb are used to obtain the FES pattern, which is applied to the afflicted limb to cause similar movement during the training period. To refine the technique further, experiments were conducted to define the most repeatable and pertinent small set of EMG parameters. Preliminary results from consecutive arm movements of three healthy subjects are presented
