title: Proximal muscle weakness in a 15-year-old boy.
abstract: Proximal muscle weakness, often indicative of a myopathy, has a broad differential diagnosis in children. We present a case of an adolescent boy with proximal weakness and a mildly elevated creatine kinase. He was found to have spinal muscular atrophy type III rather than a myopathy.
