Electrodiagnostic Case Study of Diabetic Amyotrophy: Variant of Diabetic Neuropathy

The neuropathies are very common in diabetes and one of the most important presentations is proximal neuropathy which is called as diabetic amyotrophy. Diabetic amyotrophy is a condition presented as a proximal motor neuropathy which is asymmetric and with weakening of the proximal muscles supplied by the femoral and obturator nerves and sometimes there may be distal polyneuropathy. The diabetic amyotrophy includes various elements of lumbosacral plexus and electrodiagnostic study often gives the diagnosis of neurogenic lesion affecting at the level of root called as lumbosacral radiculopathy, or involving plexus as plexopathy, or proximal neuropathy. Thus, the disorder is called lumbosacral radiculoplexus neuropathy. This article is a case study related with neurophysiological findings of diabetic amyotrophy which shows asymmetric proximal motor neuropathy.
