A coarse tremor was noted in 13 children suffering from the childhood form of spinal muscular atrophy. Tremor has not been seen in any other condition producing proximal muscle weakness in childhood, and its presence should therefore suggest the diagnosis of spinal muscular atrophy. In addition, the feet of patients with spinal muscular atrophy tended to evert, whereas in Duchenne muscular dystrophy there was either no deformity or a tendency to toe walking.
在13名患有儿童型脊髓性肌萎缩症的儿童中发现有粗大震颤。在童年期导致近端肌无力的任何其他病症中均未见到震颤，因此其出现应提示脊髓性肌萎缩症的诊断。此外，脊髓性肌萎缩症患者的足部倾向于外翻，而在杜兴氏肌营养不良症中要么没有畸形，要么有足尖行走的倾向。
