This study evaluated the effects of visual input on surface electromyography (sEMG) of some stomathognatic and neck muscles (anterior temporalis, masseter, anterior digastric and sternocleidomastoid muscles) in patients experiencing myogenous facial pain compared with healthy volunteers. All subjects kept the mandible at rest with teeth apart and underwent a 15-s sEMG recording of anterior temporalis, masseter, digastric and sternocleidomastoid muscles. Each recording was carried out with closed and then open eyes. The sEMG activity of each muscle was compared between the two groups. In the study group, anterior temporalis, masseter and sternocleidomastoid sEMG with closed eyes showed higher values compared with controls (p<0.05). In the study group, left and right anterior temporalis (p<0.003) and right digastric (p<0.03) sEMG with open eyes showed higher values than sEMG with closed eyes. In the control group no significant differences were observed between closed and open eyes. In patients with myogenous facial pain, visual input appears to be associated with a significant increase in the sEMG activity of some head and neck muscles.
本研究评估了视觉输入对患有肌源性面部疼痛的患者与健康志愿者相比，一些咀嚼肌和颈部肌肉（颞前线肌、咬肌、二腹肌前腹和胸锁乳突肌）表面肌电图（sEMG）的影响。所有受试者均使下颌在牙齿分开的情况下保持休息，并对颞前线肌、咬肌、二腹肌前腹和胸锁乳突肌进行 15 秒的 sEMG 记录。每次记录均在闭眼和睁眼状态下进行。比较两组之间的每块肌肉的 sEMG 活动。在研究组中，与对照组相比，闭眼时颞前线肌、咬肌和胸锁乳突肌的 sEMG 显示出更高的数值（p<0.05）。在研究组中，左、右侧颞前线肌（p<0.003）和右侧二腹肌（p<0.03）的睁眼 sEMG 值高于闭眼 sEMG 值。在对照组中，闭眼和睁眼之间没有观察到显著差异。在患有肌源性面部疼痛的患者中，视觉输入似乎与一些头颈部肌肉的 sEMG 活动显著增加有关。
