Figure 2

Serial nerve conduction tracings in the case. Serial recordings of compound muscle action potentials (CMAP) of the left median nerve (a) and the left posterior tibial nerve (b) on days 2, 14, and 48. Prolonged distal latencies (DL) were shown in the left median nerve and posterior tibial nerve on day 2. Distal CMAP was within the normal range; however, proximal CMAP was eliminated in the posterior tibial nerve and decreased in the median nerve. DL and CMAP improved over time on day 14 and day 48.
