ABSTRACT
BACKGROUND:
Temporomandibular disorders (TMD) is the leading cause of pain and disability among frequently occurring facial pain and the second leading cause of musculoskeletal conditions.AIM:
We examined whether acupuncture could alleviate pain intensity in patients with temporomandibular disorders (TMD). DESIGN ANDMETHODS:
Sixty participants with TMD were randomly assigned (ratio 11) to receive three acupuncture or sham acupuncture sessions weekly for 4 weeks. The primary outcome was the change in the mean weekly pain intensity from baseline to week 4. Secondary and exploratory outcomes included proportion of participants with ≥30% or ≥ 50% reduction in pain intensity, change in jaw opening and movement, graded chronic pain scale, jaw functional limitations scale-20-item, Depression, Anxiety and Stress Scales-21, Pittsburgh sleep quality index at week 4 and 8, and the pressure pain threshold and surface electromyography at week 4. RESULTS ANDCONCLUSION:
The acupuncture group showed significantly reduced pain intensity compared to the sham group at week 4 (-1.49, 95% confidence interval [CI] -2.32 to -0.65; P < 0.001) and week 8 (-1.23, 95% CI -2.11 to -0.54; P = 0.001). Acupuncture's effectiveness surpassed sham's at 4 weeks and lasted 8 weeks. Participants in the acupuncture group experienced significantly greater improvements in the 30% and 50% response rate, jaw opening and movement, GCPS, JFLS-20, DASS-21 and PSQI than those in the sham acupuncture group. There were no significant between-group differences in PPT and sEMG. In summary, acupuncture provided marked pain relief and improvement in physical and emotional function for patients with TMD compared with sham acupuncture.
