Electromyographic investigations into the function of the two individual heads of the lateral pterygoid muscle in normal persons are compared with patients suffering the pain of temporomandibular joint dysfunction and those with painless clicks. The results indicate that the lower head of the lateral pterygoid muscle, normally active only when depressing, protruding and deviating the mandible, becomes active on closing and clenching in patients suffering pain. Patients with painless clicks behave as normals. These results are discussed and a theory is presented which suggests that temporomandibular joint dysfunction has a simple pathological basis.
对正常人翼外肌两个独立头的功能进行肌电图检查，并与患有颞下颌关节功能紊乱疼痛的患者以及无痛性弹响的患者进行比较。结果表明，翼外肌下头通常仅在使下颌骨下压、前伸和侧偏时活跃，而在疼痛患者中，其在闭口和紧咬时也变得活跃。无痛性弹响的患者表现正常。对这些结果进行了讨论，并提出了一种理论，该理论表明颞下颌关节功能紊乱有一个简单的病理基础。
