Clinical use of nerve stimulation and recording techniques.

The use of nerve stimulating and recording techniques intraoperatively contributes to clinical assessment of peripheral nerve injuries in certain reconstructive procedures. Unfortunately, the electrical technology required to perform these tests often discourages the clinician from its common usage. Twenty-two patients were studied. Eight patients had stimulation only of motor or sensory fascicles performed to enhance alignment. In 14 patients, stimulation and recording techniques were utilized to evaluate neuroma incontinuities or brachial plexus injuries. In 5 of these 14 patients, the intraoperative determinations altered or aided the surgical management. The parameters of electrical safety, estimated costs, and illustrated clinical applications are outlined.
