1. An apparatus for localization of a target nerve comprising:

  • i. a generator for the production of electrical current at physiological stimulation frequencies;

    ii. one or more probe electrodes for coupling to the generator to transmit the electrical current to the target nerve;

    iii. one or more physiological sensors for determining the proximity of the one or more probe electrodes to the target nerve, the sensors sensing and signaling multifidus muscle activity resulting from the transmission of electrical current to the target nerve by the probe electrodes; and

    iv. a measuring device for reporting the physiological sensor signals to indicate the proximity.
