[The significance of an electromyographic study of the femoral nerve in diabetics].
The author examined groups of 25 diabetics with proximal diabetic neuropathy, 25 with distal diabetic neuropathy and a control group of 25 healthy subjects. Lesions of the femoral nerve in patients with proximal diabetic neuropathy are characterized by the presence of denervation potentials (80%) and changes of action potentials in the m. quadriceps femoris, a change in the shape of the M-response (only 12% within the normal range) and a reduction of the terminal conduction rate of the femoral nerve (34 +/- 12.3 m/s). In the discussion the author draws attention to technical and anatomical problems of the examination of the femoral nerve and to the interpretation of results with regard to the pathogenesis and clinical aspects. The recommended method of EMG examination of the femoral nerve is technically easy even for EMG laboratories which possess only simple equipment.
