An assembly of mains electricity (AC-powered) devices designed to locate a nerve by applying an electrical stimulus with a probe and comparing muscle responses as the probe is moved. Once the pathways are located, their transmission capabilities can be assessed by comparing observed muscle responses with the expected maximum contractions. The system typically includes an electrical pulse generator, appropriate electrodes, sensors to detect muscle response (e.g., a strain gauge), and audible and/or visual indicators. It is used during the diagnosis and assessment of nerve function and to locate nerves during surgery to reduce the incidence of accidental injury.
