This study evaluated the electromyographic characteristics of masticatory and neck muscles in subjects with vestibular lesions. Surface electromyography of the masseter, temporalis and sternocleidomastoid muscles was performed in 19 patients with Ménière's disease, 12 patients with an acute peripheral vestibular lesion, and 19 control subjects matched for sex and age. During maximum voluntary clenching, patients with peripheral vestibular lesions had the highest co-contraction of the sternocleidomastoid muscle (analysis of covariance, p=0.02), the control subjects had the smallest values, and the patients with Ménière's disease had intermediate values. The control subjects had larger standardized muscle activities than the other patient groups (p=0.001). In conclusion, during maximum voluntary tooth clenching, patients with vestibular alterations have both more active neck muscles, and less active masticatory muscles than normal controls. Results underline the importance of a more inclusive craniocervical assessment of patients with vestibular lesions.
本研究评估了前庭病变患者咀嚼肌和颈部肌肉的肌电图特征。对19例梅尼埃病患者、12例急性外周前庭病变患者以及19名年龄和性别匹配的对照受试者进行了咬肌、颞肌和胸锁乳突肌的表面肌电图检查。在最大自主紧咬期间，外周前庭病变患者的胸锁乳突肌共同收缩程度最高（协方差分析，p = 0.02），对照受试者的值最小，梅尼埃病患者的值居中。对照受试者的标准化肌肉活动比其他患者组更大（p = 0.001）。总之，在最大自主紧咬期间，前庭功能改变的患者与正常对照相比，颈部肌肉更活跃，咀嚼肌则不太活跃。结果强调了对前庭病变患者进行更全面的颅颈评估的重要性。
