A comparison of sural nerve conduction studies in patients with impaired oral glucose tolerance test

Abstract

Sural nerve studies should be of value to determine neuropathy in IGT patients. This study supported the idea that IGT is a transitional state before diabetes and also the importance of the dorsal sural nerve latencies for early detection of neuropathy.

Assessment of the Medial Dorsal Cutaneous, Dorsal Sural, and Medial Plantar Nerves in Impaired Glucose Tolerance and Diabetic Patients With Normal Sural and Superficial Peroneal Nerve Responses

“…The results of this study confirm previous reports on the clinical utility of assessing these nerves in hyperglycemic patients (4–9,15). Also, these results are clinically significant in that this is the first study to date that has performed NCSs of all three distal sensory nerves simultaneously and compared the results among IGT, DM, and HC groups.…”

“…Although there are still controversies about the relationship between IGT and DPN, studies that include epidermal fiber count (13) and NCSs (10,11,14) have confirmed that neuropathic changes occur in IGT well before the progression to DM. A previous study reported changes that are detectable by DS NCSs (15) in IGT patients, but little is known about whether NCSs of the other sensory nerves reflect early DPN changes in IGT patients.…”

Electrophysiological status of sural nerves in type 2 diabetes mellitus patients before symptomatic peripheral neuropathy

“…Impaired glucose tolerance (IGT) is a transitional state before diabetes and the dorsal sural nerve latencies are important for early detection of neuropathy. Sural nerve studies should be of value to determine neuropathy in IGT patients [18].…”

Brainstem auditory evoked potentials and middle latency auditory evoked potentials in patients with impaired glucose tolerance

“…Pronounced prolongation in the latency of the H reflex recorded from the left vastus medialis muscle has been observed in patients with IGT compared with a control group [23]. It has been proposed that the latency of the dorsal sural nerve is a good indicator of neuropathy in the early stages of glucose intolerance [24]. In our study, although significant prolongation was detected in tibial nerve distal motor latencies, no significant difference was detected in any other electrophysiological parameter when compared with the control group.…”
