Abstract

The article cites the case of a 5 year old boy with motor retardation presented with proximal weakness maximal in the lower limbs and generalized muscular atrophy. The deep tendon reflexes were absent. Tremor or fasciculations were not seen. The muscles of the boy were examined by a high resolution ultrasound system and real time compound imaging. Muscle fibres of the denervated motor unit atrophy. Reinnervation by collateral sprouting results in grouping of hypertrophic fibres with the same histochemical type, commonly called "type grouping".
