Abstract

Methods and systems are disclosed for electrically stimulating a nerve to cause muscle contraction. In one arrangement, a plurality of electrodes is positioned in contact with skin. The electrodes allow electrical stimulation to be directed independently towards a plurality of different stimulation regions below the skin via a corresponding plurality of combinations of the electrodes. For each combination of electrodes, a test stimulation is applied using the combination of electrodes and a response to the test stimulation is measured. One or a subset of stimulation regions is selected based on the measured responses. A therapy stimulation is applied to each selected stimulation region using the combination of electrodes corresponding to the selected stimulation region.
