Twenty-five symptoms, signs, and abnormal investigations were looked for in 20 patients with clinically-definite myotonic dystrophy. Weakness of facial muscles, neck flexors, and arm external rotators was found in all patients (sensitivity = 100%). Arm external rotation has not been reported as a frequently involved muscle in previous clinical studies on myotonic dystrophy. Careful examination of muscle strength may therefore predict which patients may or may not carry the abnormal gene for myotonic dystrophy.
在20例临床确诊的强直性肌营养不良患者中，对25种症状、体征及异常检查指标进行了查找。所有患者均存在面部肌肉、颈部屈肌及手臂外旋肌无力（敏感性 = 100%）。在以往关于强直性肌营养不良的临床研究中，手臂外旋肌未被报道为经常受累的肌肉。因此，仔细检查肌力可能有助于预测哪些患者携带或未携带强直性肌营养不良的异常基因。
