Nerve conduction studies in the present case. a Motor conduction study of the right ulnar nerve shows prolonged latency in proximal stimulations, conduction block between the wrist and elbow, and decreased conduction velocity between the wrist and elbow and across the elbow. b Motor conduction study of the right posterior tibial nerve shows prolonged latency in proximal stimulation, conduction block between the ankle and popliteal fossa, and decreased conduction velocity between the ankle and popliteal fossa.

Nerve conduction studies for the right ulnar nerve and posterior tibial nerve revealed prolonged distal latency, conduction block, and decreased conduction velocity, suggesting demyelinating neuropathy (Fig. 1).
