DIABETES MELLITUS-DIABETIC AMYOTROPHY

SUMMARY

1. Distinct from other forms of diabetic neuropathy.

2. Characterized by weakness followed by wasting of pelvifemoral muscles, either unilaterally or bilaterally, with associated pain.

3. Sensory impairment is minimal in the cutaneous distribution sharing the same root or peripheral nerve as affected musculature. A concomitant distal predominantly sensory neuropathy may be present.

4. Onset is in middle age or later, although it may occur in youth.

5. Electrodiagnostic studies: neurogenic lesion attributable to a lumbosacral radiculopathy, plexopathy, or proximal crural neuropathy.

6. The natural course of the illness is variable with gradual but often incomplete improvement.
