Efficacy of physiotherapy in reducing pain in subjects with temporomandibular disorders: a systematic review with network meta-analysis
TL;DR
MT and TE are effective strategies for reducing pain in subjects with TMDs and should be used as first-line interventions before more invasive treatments; the combination of dry needling and manual therapy appears to be the most effective approach.
Abstract
Background: Temporomandibular disorders (TMDs) are common conditions in the general population. Several therapeutic approaches are available, but there is no consensus on the most effective, particularly in physiotherapy. Objectives: To assess the efficacy of manual therapy (MT) and therapeutic exercise (TE) in reducing pain in patients with TMDs. Methods: Four databases (MEDLINE, PEDro, EMBASE, CINAHL) were searched up to March 2025. We included randomized controlled trials (RCTs) evaluating the effects of MT and/or TE in individuals with TMDs, compared to any other rehabilitation treatment, with pain intensity as the primary outcome. The methodological quality was assessed using the PEDro scale. A network meta-analysis was performed to compare the effectiveness of different rehabilitative approaches. Results: 25 RCTs for a total of 1,540 people were included. The main comparisons were: MT and/or TE vs no treatment or placebo, occlusal splint, and instrumental physiotherapy. In most studies, MT and TE were more effective than controls in reducing pain. However, the network meta-analysis indicated that multimodal treatments were the most effective. The methodological quality of the included studies ranged from 3 to 9 points. Conclusion: MT and TE are effective strategies for reducing pain in subjects with TMDs and should be used as first-line interventions before more invasive treatments; the combination of dry needling and manual therapy appears to be the most effective approach. Nonetheless, the variability in study quality suggests that further high-quality research is needed to confirm these findings.
