Amplitudes from sites as follows: median – wrist at 7 cm, elbow, axilla; ulnar – wrist at 7 cm, below elbow, above elbow, axilla; peroneal – ankle at 9 cm, below fibular head, above fibular head; tibial – ankle at 9 cm, popliteal fossa. § The first value is the distal motor latency and subsequent values segmental velocities. ¥ F-wave persistence and chronodispersion not recorded in the medical records
