Electrophysiological recordings in peripheral nerve surgery: a review.

The use of electrophysiological techniques as an adjunct in the surgical repair of peripheral nerve injuries can improve the quality of the repair and thus the degree of functional recovery. These techniques provide objective information needed to assess the degree of injury and can assist the surgeon in making proper decisions regarding treatment of peripheral nerve lesions. The purposes of this paper are to review: (1) the current theories of the functions of peripheral nerves and their and organs, (2) the development of electrophysiological techniques, (3) the principles involved in their use, and (4) the present and possible future applications of these techniques in peripheral nerve surgery and to outline them.
