A
system comprising a controller for providing and receiving signalling to and from at least one electrical stimulation, ES,
system, comprising an
electrode array for applying an electrical stimulation to a
muscle and one or more sensors for detecting a response of the
muscle; the ES
system is configured to selectively operate the
electrode array in one of a
motor point scan mode or a stimulation mode, wherein: in the
motor point scan mode a plurality of scan measurements are taken between different pairs of electrodes; and based on measurement signalling of each scan measurement, the controller is configured to identify a first stimulation
electrode and a second stimulation electrode; and in the stimulation mode a plurality of stimulation signals are applied to the first and second stimulation electrodes to provide for contraction of the
muscle.
