Stimulation parameters for increased muscle force and selectivity of elbow extensors in chronic stroke subjects

Functional electrical stimulation (FES) has been shown to be a promising technique to retrain the grasping ability in subjects with unilateral brain lesion. In order to extend this technique to more proximal arm functions for reaching in subjects with chronic stroke, the electrical stimulation parameters need to be carefully chosen. Muscle selectivity and sufficient force generation are crucial for the development of efficient training paradigms that augment reaching capabilities. Isometric torque measurements in the elbow joint and EMG recordings were performed to evaluate optimal parameters for commonly used stimulation patterns. The results from eight chronic stroke subjects showed that shorter pulse durations produced higher torques and stimulated more selectively the target muscle in brain injured subjects.
