Nerve Conduction Study Protocol

Nerve conduction studies were performed only on visit 1 by a senior consultant neurophysiologist. Nerve conduction studies of the common peroneal (including F wave studies) and sural nerves in the right leg were performed with a Medtronic Keypoint device (Medtronic, Minneapolis, MN, USA). Nerve conduction studies were performed once at the baseline visit for all patients. Sural antidromic sensory action potentials of <5 μV amplitude and <40 m/s conduction velocity, and common peroneal nerve (compound muscle action potential from extensor digitorum brevis) values <3 mV amplitude, <40 m/s conduction velocity, were considered abnormal (35 (link)).
