Electrodiagnostic evaluation of diabetic polyneuropathy

In this prospective study, 47 cases of diabetes mellitus [IDDM and NIDDM] suspected of diabetic neuropathy were studied to delineate the underlying pathology and localize lesion. Nerve conduction studies [NCS] were performed with MS 6 [MEDLEC] using surface electrodes. Concentric needle electromyography was done using Neuropack electromyographic model MEM7102K. On the basis of electrophysiological studies 39 patients had diabetic neuropathy, rest of patients had radiculopathies, thoracic outlet syndrome [TOS] and other abnormalities. Electrodiagnostic studies were helpful in confirming the diagnosis, localizing the entrapment neuropathies and in segregating the axonal/demyelinating neuropathies
