To ALS patients, except for the test of regular three-limb muscles, we suggest that tests of thoracic paraspinal muscles and sternocleidomastoid muscle be added with electromyography so as to raise the positive rate and accuracy in early ALS diagnosis.

• 对ALS患者除行常规3肢体肌的肌电图检测外,应加做胸段棘旁肌和胸锁乳突肌,以提高ALS早期诊断的阳性率和准确性。
