1. A neural monitoring device, comprising:

  • a stimulator configured to provide a stimulus within an intracorporeal treatment area of a subject;

    a non-invasive mechanical sensor configured to;

    be placed in contact with an external skin surface of the subject and in direct mechanical communication with a muscle of the subject; and

    generate an output signal corresponding to a sensed mechanical response of the muscle; and

    a processor configured toreceive the output signal from the mechanical sensor;

    provide a first indicator if the sensed mechanical response is attributable to a depolarization of a nerve that is caused by the provided stimulus; and

    provide a second indicator if the sensed mechanical response is not attributable to the provided stimulus.
