The main aim of this study is to evaluate the effects of painful muscle form of temporomandibular disorders and myopia on the connections between the visual organ, the bioelectrical activity and sensitivity of the masticatory and cervical muscles, and sleep quality. Subjects were divided into 4 groups (Myopia & TMDs, Myopia (Without TMDs), Emmetropic & TMDs and Emmetropic (Without TMDs)). The study was conducted in the following order of assessment: examination for temporomandibular disorders, assessment of the muscle activity by electromyograph, pressure pain thresholds examination, ophthalmic examination and completion of the Pittsburgh Sleep Quality Index. It was observed that the Myopia & TMDs group had higher muscle tenderness, higher resting and lower functional muscle bioelectrical activity. The visual organ is clinical related to the masticatory and cervical muscles. TMDs and myopia alter masticatory and cervical muscle activity. The thickness of the choroid in people with myopia is related to muscle tenderness. TMDs and myopia impair sleep quality. It is recommended to determine the number of people with refractive error and its magnitude in the sEMG study in order to be able to replicate the research methodology.
本研究的主要目的是评估颞下颌关节紊乱和近视的疼痛肌肉形式对视觉器官、咀嚼肌和颈肌的生物电活动和敏感性以及睡眠质量之间的联系的影响。受试者分为 4 组（近视伴 TMD、近视不伴 TMD、正视伴 TMD 和正视不伴 TMD）。研究按以下评估顺序进行：颞下颌关节紊乱检查、肌电图检查、压痛阈值检查、眼科检查和匹兹堡睡眠质量指数评分。结果观察到，近视伴 TMD 组肌肉压痛程度更高，静息时肌肉生物电活动更低，功能时肌肉生物电活动更高。视觉器官与咀嚼肌和颈肌在临床上相关。TMD 和近视会改变咀嚼肌和颈肌的活动。近视患者脉络膜厚度与肌肉压痛有关。TMD 和近视会影响睡眠质量。建议在 sEMG 研究中确定屈光不正的人数及其程度，以便能够复制研究方法。
