The presence of hand and electrocardiogram (ECG) tremor was studied in 31 children with severe, intermediate, or mild form of spinal muscular atrophy. Clinical tremor of the hands was seen in 16 (59%) of 27 patients, all with benign forms of the disease. Nineteen patients had ECG tremors, of whom 17 had the mild or intermediate form. With the exception of one, all patients in the mild or intermediate group had hand or ECG tremor. Hand and ECG tremor are valuable in the diagnosis of the benign forms of spinal muscular atrophy; they are of no value in diagnosis of the severe infantile type.
对31例患有重度、中度或轻度脊髓性肌萎缩症的儿童进行了手部震颤和心电图（ECG）震颤的研究。27例患者中有16例（59%）出现手部临床震颤，均为病情良性的患者。19例患者有心电图震颤，其中17例为轻度或中度。除1例患者外，轻度或中度组的所有患者均有手部或心电图震颤。手部震颤和心电图震颤对脊髓性肌萎缩症良性形式的诊断有价值；对重度婴儿型的诊断无价值。
