Electrophysiological studies in familial spastic paraplegia.

Abstract

Motor and sensory conduction studies have been performed in 10 patients from three families with uncomplicated familial spastic paraplegia whose ages ranged from 4 to 41 years. In all cases the values fell within the control range. The findings may be contrasted with those in Friedreich's ataxia and some other spinocerebellar degenerations in which peripheral nerve abnormalities are present.
