[Purpose] This study investigated the effectiveness of a short-term exercise program combining range-of-motion exercise for the temporomandibular joint and self-traction therapy in patients with temporomandibular joint disc displacement without reduction. [Subjects and Methods] The study participants comprised 36 females with jaw trismus and moderate to severe functional pain. The range-of-motion exercise for the temporomandibular joint was performed at the first visit by the therapist, and the patients were instructed to perform self-traction therapy in the morning and during daily bathing until the next visit 2 weeks later. Maximum mouth opening distance and the visual analogue scale score were used to compare pain on motion and mastication as well as the impact of the program on daily activities at the first consultation and 2 weeks later. [Results] All symptoms were significantly improved after 2 weeks of treatment. [Conclusion] A program that combines exercise for the temporomandibular joint and self-traction therapy can improve range of motion at the joint in the short term and reduce pain and difficulty associated with daily activity in patients with temporomandibular joint disc displacement without reduction. The results of this study suggest that such a program can serve as an effective conservative treatment.
[目的] 本研究调查了一项短期运动计划的有效性，该计划结合了颞下颌关节活动度训练和自我牵引疗法，用于治疗不可复性颞下颌关节盘移位患者。[对象与方法] 研究参与者包括36名患有牙关紧闭和中度至重度功能性疼痛的女性。颞下颌关节活动度训练由治疗师在首次就诊时进行，患者被指导在早晨和日常沐浴时进行自我牵引疗法，直到2周后的下次就诊。使用最大开口距离和视觉模拟评分量表来比较首次咨询时和2周后运动及咀嚼时的疼痛情况以及该计划对日常活动的影响。[结果] 治疗2周后所有症状均有显著改善。[结论] 结合颞下颌关节运动训练和自我牵引疗法的计划可在短期内改善关节活动度，并减轻不可复性颞下颌关节盘移位患者与日常活动相关的疼痛和困难。本研究结果表明，这样的计划可作为一种有效的保守治疗方法。
