Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p> <italic>Introduction</italic>: To evaluate the sensitivity of electrophysiologic assessments, we compared F‐waves and motor and sensory nerve conduction studies (MNCS and SNCS) in patients with diabetes mellitus (DM). <italic>Methods</italic>: We tested median, ulnar, tibial, and fibular nerves in 132 DM patients divided into those with and without clinical evidence of polyneuropathy. <italic>Results</italic>: Of 64 asymptomatic patients, 2 (3%) had MNCS or SNCS abnormalities, both of whom had F‐wave changes, whereas 21 (33%) had only delayed F‐waves, for a combined yield of 23 (36%). The corresponding values for 68 symptomatic patients consisted of 43 (63%), 14 (21%), and 57 (84%). In both groups, F‐wave latency had a higher (<italic>P</italic> &lt; 0.05) frequency of abnormality than MNCS in all nerves. F‐wave study also surpassed SNCS in lower limb nerves. <italic>Conclusions</italic>: F‐waves of the tibial and fibular nerves are the most sensitive measure to detect subclinical or overt diabetic polyneuropathy. <italic>Muscle Nerve</italic><bold>49</bold>: 804–808, 2014</p> </abstract>
