Fig. 4. Motor evoked potential (MEP) recorded in abductor pollicis brevis muscle. The onset latency of MEP is 25.55 ms in the right and 26.22 ms in the left. The central motor conduction time calculated by subtracting (F-wave latency+M-wave latency−1)/2 from the corresponding MEP latency shows a delay; 12.15 ms and 12.42 ms from each side.
