OBJECTIVE
To assess the reduction in pain, muscle tenderness, joint clicking, and improvement in mouth opening (MO) after low-level laser therapy (LLLT) compared to transcutaneous electrical nerve stimulation (TENS) and therapeutic ultrasound (US) among temporomandibular joint disorder (TMD) patients.
METHODS
A systematic search of online sources of electronic databases was undertaken. The quality of the study was assessed using the Cochrane risk of bias assessment tool for randomized controlled trials (RCTs).
RESULTS
Twelve RCTs were included in the systematic review, and 9 were included in the meta-analysis. For reduction in pain between LLLT and TENS, LLLT was found to be better than TENS, at 95% CI. LLLT was also proven to be better in reducing pain than therapeutic US, at 81% CI.
CONCLUSION
This systematic review and meta-analysis compared the effectiveness of LLLT, TENS, and therapeutic US in TMD. LLLT provided relatively more effective pain relief and improvement in MO.
目的
评估低水平激光疗法（LLLT）与经皮神经电刺激（TENS）和治疗性超声（US）相比，在减轻颞下颌关节紊乱（TMD）患者疼痛、肌肉压痛、关节弹响和张口度（MO）改善方面的效果。
方法
对电子数据库的在线资源进行系统搜索。使用 Cochrane 随机对照试验（RCT）偏倚风险评估工具评估研究质量。
结果
系统评价纳入了 12 项 RCT，其中 9 项纳入了荟萃分析。对于 LLLT 和 TENS 之间疼痛减轻的比较，在 95%置信区间内，LLLT 优于 TENS。在 81%置信区间内，LLLT 在减轻疼痛方面也优于治疗性 US。
结论
本系统评价和荟萃分析比较了 LLLT、TENS 和治疗性 US 在 TMD 中的疗效。LLLT 提供了相对更有效的疼痛缓解和 MO 改善。
