Lack of motor progression in isolated sensory peripheral neuropathy.

摘要

Nerve conduction studies (NCS) and electromyography (EMG) studies are critical for the detection, diagnosis, and characterization of peripheral neuropathy (PN). Although NCS and EMG abnormalities are often compared to clinical findings, these data are not always concordant. Examples of this discordance include patients with small fiber PN having severe deficits of nociceptive and thermal function but normal NCS, or patients with Charcot-Marie-Tooth disease type 1A with minimal symptoms but florid NCS changes. The utility of using NCS/EMG for prediction of later clinical outcomes is also unclear in many forms of PN.
