Electrical Stimulation Use in Upper Extremity Peripheral Nerve Injuries

Peripheral nerve injuries can be debilitating and often have a variable course of recovery. Electrical stimulation (ES) has been used as an intervention to attempt to overcome the limits of peripheral nerve surgery and improve patient outcomes after peripheral nerve injury. Little has been written in the orthopaedic literature regarding the use of this technology. The purpose of this review was to provide a focused analysis of past and current literature surrounding the utilization of ES in the treatment of various upper extremity peripheral nerve pathologies including compression neuropathies and nerve transection. We aimed to provide clarity on the clinical benefits, appropriate timing for its employment, risks and limitations, and the need for future studies of ES.
