Figure 1. Nerve conduction studies (NCSs) waveforms for patient 1.

Motor responses of the left peroneal nerve (recording from extensor digitorum brevis and tibialis anterior) and tibial nerve (recording from abductor hallucis) were absent. Motor response of the left median nerve was normal. Sensory response of the left sural nerve was absent. Sensory NCS of the left radial nerve was borderline normal. [Of note, this was a bedside study].
