title: The wasted leg syndrome, a single fibre electromyographic study of arms and legs.
abstract: Single fibre electromyography (SFEMG) was performed on 11 patients with the wasted leg syndrome. Five were of South Asian origin and the others Chinese. In most cases the disorder progressed for about 5 yr before becoming static or very slowly progressive. The SFEMG fibre density was increased similarly in both the affected and less affected leg, but was normal in the arms except for a few longstanding cases. The limited extent of clinical and electrophysiological abnormalities suggests that the wasted leg syndrome is a distinct entity.
