[Late post-poliomyelitic muscular atrophy. Apropos of 14 cases].

The authors report 14 cases of late post-poliomyelitis muscular atrophies. The atrophy appears many years after the acute episode of anterior poliomyelitis. Several types of disorders were observed: extension of weakness and wasting; chronic spinal amyotrophy; amyotrophic lateral sclerosis without bulbar atrophy, coincidental muscular dystrophy. These cases have been interpreted in different ways. Further studies are necessary.
