Electrodiagnostic studies (NCS/EMG)

Findings: The results of the nerve conduction studies are abnormal for: 1) moderate to severe increase in the left median, ulnar and peroneal distal motor latencies, 2) absent left ulnar F-wave latency, 3) reduced left peroneal, ulnar, and median motor nerve conduction velocities with temporal dispersion, and 4) partial conduction block of the left ulnar across the elbow.
