Objective:
The aim of this systematic review was to analyze the effectiveness of exercise and manual therapy interventions in patients with disc displacement without reduction.
Method:
The authors performed a systematic review of Medline, EMBASE, PEDro, CINAHL, and Google Scholar databases. Two independent reviewers conducted the eligibility and quality assessment of studies. Interventions based on exercise and manual therapy regarding pain intensity and maximum mouth opening as primary outcomes were examined.
Results:
Ten articles were included, according to the inclusion criteria. Most of the interventions showed statistically significant improvements in the primary outcomes.
Conclusion:
Results show that interventions based on therapeutic exercise or manual therapy may be beneficial and play a role in the treatment of disc displacement without reduction. Limited evidence suggests that exercise significantly improves mouth opening in comparison to splints. Due to the heterogeneity of the included studies, these results should be interpreted with caution.
