A nerve stimulation apparatus is provided. The nerve stimulation apparatus detects nerve activities from a body surface and applies stimulation. The nerve stimulation apparatus includes a stimulation apparatus with multiple electrodes which are arranged on skin and a current supply unit which supplies a current to the electrodes which stimulation apparatus provides the current to a living body percutaneously to stimulate a target nerve a measurement apparatus which measures activities of muscles governed by the nerve according to the stimulation from the stimulation apparatus and an information processing apparatus which determines based on a measurement result of the nerve activities obtained from the measurement apparatus which electrode is capable of providing the target nerve activities equal to or greater than a desired value.
