Detection of denervation in muscles in the craniobulbar area is important to assure widespread lower motor neuron involvement in the diagnosis of amyotrophic lateral sclerosis (ALS). The value of spontaneous activity analysis in needle electromyography (EMG) of the tongue has been questioned in the recent literature.
Spontaneous activity in the tongue and sternocleidomastoid (SCM) muscles was reviewed retrospectively in 17 ALS patients.
Needle EMG showed spontaneous activity in the tongue in 14 of 17 patients (82%) and in 6 patients of 17 (35%) in SCM. Spontaneous EMG activity in the tongue was found in patients with and without bulbar symptoms.
Needle EMG is a valuable method for assessing clinical and subclinical involvement of the tongue in patients with bulbar and limb onset ALS. Adequate relaxation of the tongue is a prerequisite for proper spontaneous activity recording.
检测颅神经支配区域肌肉的去神经支配对于确保广泛的下运动神经元参与肌萎缩侧索硬化症（ALS）的诊断非常重要。在最近的文献中，舌针肌电图（EMG）中自发性活动分析的价值受到了质疑。
回顾性分析了 17 例 ALS 患者的舌和胸锁乳突肌（SCM）的自发性活动。
17 例患者中有 14 例（82%）舌针 EMG 显示自发性活动，17 例中有 6 例（35%）SCM 有自发性活动。舌的自发性 EMG 活动见于有和无球部症状的患者。
针肌电图是评估有球部和肢体起病 ALS 患者舌部临床和亚临床受累的有价值的方法。舌的充分松弛是进行适当的自发性活动记录的前提条件。
