Abstract
Electrical stimulation is carried out by surface electrodes, placed at grid points over the forearm surface. Three orthogonal components of the isometric moment generated at the wrist joint are measured and these moment vectors are charted. The charts reveal both qualitative and quantitative information on the magnitude and direction of the resultant moment vector generated, as a function of the stimulation current level, and the electrode positioning. Clearly defined plateaux of unidirectional moment vectors are found to exist. These are analysed in greater detail.
