We investigated electromyography (EMG) of the sternocleidomastoid (SCM) in 128 patients with amyotrophic lateral sclerosis (ALS) including correlation with forced vital capacity (FVC) and ALS Functional Rating Scale scores. The presence of fibrillation potentials and positive sharp waves in the SCM was significantly more frequently observed in patients with an FVC <80% (31/49, 63%) than in patients with an FVC≥80% (34/79, 43%). This study suggests that the SCM could be concomitantly involved with primary respiratory muscles in ALS. This is of value since needle EMG is a less invasive procedure in SCM than in the diaphragm or intercostal muscles.
我们对128例肌萎缩侧索硬化症（ALS）患者的胸锁乳突肌（SCM）进行了肌电图（EMG）检查，包括其与用力肺活量（FVC）和ALS功能评定量表评分的相关性。FVC<80%的患者（31/49，63%）胸锁乳突肌中纤颤电位和正锐波的出现频率显著高于FVC≥80%的患者（34/79，43%）。本研究表明，在肌萎缩侧索硬化症中胸锁乳突肌可能与主要呼吸肌同时受累。这具有重要意义，因为针电极肌电图检查在胸锁乳突肌中比在膈肌或肋间肌中侵入性更小。
