Experimental setup. Isometric contractions of the right biceps brachii muscle during delivery of FES were measured using a dynamometer. The axis of the dynamometer was aligned to the axis of rotation of the elbow joint. A switch was designed to change the stimulator source between MyndMove™ and Compex Motion delivered through the same leads, ensuring consistent electrode placement. Example current pulses for MyndMove™ and Compex Motion are shown in the output stage of the switch, highlighting the difference in shape and amplitude.
