title: Muscle weakness in infants with rickets: distribution, course, and recovery.
abstract: We describe the distribution, progression, and resolution of muscle weakness, wasting, and hypotonia in three infants with rickets due to different causes. Progressive muscle weakness affecting preferentially the proximal muscles of the legs and failure to gain weight were the presenting symptoms. The skeletal signs appeared later in the course of the illness and the time for resolution of the neuromuscular findings varied with the etiology of the disorder.
