BACKGROUND: Exercise therapy is occasionally considered as an initial treatment for temporomandibular disorders. However, pain can be exacerbated during exercise therapy.
OBJECTIVE: To investigate the immediate curative effects of exercise therapy in patients with masticatory muscle myalgia.
METHODS: Fifty-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-Whitney U test was used for the subgroup comparisons.
RESULTS: Mouth 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).
CONCLUSION: Exercise therapy immediately enlarged the mouth opening distance and reduced myalgia; therefore, it could be helpful in managing masticatory muscle myalgia.
