运动疗法有时被认为是颞下颌关节紊乱病的初始治疗方法。然而，运动治疗过程中疼痛可能会加剧。Objectives探讨咀嚼肌肌痛患者运动治疗的即时疗效。治疗师进行运动疗法（将疼痛的咬肌和/或颈部肌肉沿着肌肉收缩的方向拉伸），共10轮牵引，每轮持续10 s。使用Wilcoxon符号秩检验比较患者在运动治疗前和运动治疗后即刻的无痛最大张口距离和疼痛程度（VAS值）。Mann-WhitneyU检验用于亚组comparations.ResultsMouth开放增加从41（IQR 38-43）到46（IQR 43-48）毫米和疼痛缓解从48（IQR 31-56）到21（IQR 10-56）后立即运动疗法（p<0.001）。无患者在运动后出现疼痛加重或张口度降低。不同性别、疼痛侧、疼痛部位和治疗师的张口距离变化无差异（均为p> 0.05）。单侧疼痛患者（26，IQR 12-39）的疼痛减轻程度大于双侧疼痛患者（13，IQR 5-25）（p= 0.019）。根据性别，疼痛部位和治疗师的疼痛程度的变化没有差异（p> 0.05所有）。结论运动疗法立即扩大张口距离，减少肌痛，因此，它可能有助于管理咀嚼肌肌痛。
BackgroundExercise therapy is occasionally considered as an initial treatment for temporomandibular disorders. However, pain can be exacerbated during exercise therapy.ObjectiveTo investigate the immediate curative effects of exercise therapy in patients with masticatory muscle myalgia.MethodsFifty‐nine patients with masticatory muscle myalgia were included. Therapists performed exercise therapy (stretched the painful masseter and/or cervical muscles along the direction of muscle contraction) in 10 rounds of traction, each lasting 10 s. The patient's pain‐free maximum mouth opening distance and degree of pain (VAS value) before and immediately after exercise therapy were compared using the Wilcoxon signed‐rank test. The Mann–WhitneyUtest was used for the subgroup comparisons.ResultsMouth opening increased from 41 (IQR 38–43) to 46 (IQR 43–48) mm and pain alleviation from 48 (IQR 31–56) to 21 (IQR 10–56) immediately following exercise therapy (p< .001 for both). None of the patients experienced pain exacerbation or reduction in mouth opening post‐exercise. No difference in mouth opening distance changes according to sex, painful side, painful site and therapist were observed (p> .05 for all). Pain reduction was greater in patients with unilateral pain (26, IQR 12–39) than those with bilateral (13, IQR 5–25) (p= .019). There were no differences in the change in the degree of pain according to sex, painful site and therapist (p> .05 for all).ConclusionExercise therapy immediately enlarged the mouth opening distance and reduced myalgia; therefore, it could be helpful in managing masticatory muscle myalgia.
