Temporomandibular disorders (TMDs) comprise a number of signs and symptoms affecting the masticatory muscles, temporomandibular joint (TMJ), or both. Because of the multifactorial etiology of such problems, the treatment usually involves more than one modality.
Therefore, the aim of this study was to compare the effectiveness of transcutaneous electric nerve stimulation (TENS) and low-level laser therapy for the treatment of patients with TMD. Materials and Methods: The clinical trial was performed with 60 patients diagnosed with TMD of multiple causes. All the patients received both methods of treatment in 6 consecutive weeks. A paired t-test was applied to verify the significance of the results. Results: A significant improvement in the range of motion and pain relief for both the therapies was observed.
Comparatively after analyzing the two methods, the values obtained after LLLT were significantly higher than those obtained after TENS therapy (P < 0.01).
颞下颌关节紊乱病（TMDs）包括一系列影响咀嚼肌、颞下颌关节（TMJ）或两者的体征和症状。由于此类问题的病因是多因素的，治疗通常涉及不止一种方式。
因此，本研究的目的是比较经皮电刺激神经疗法（TENS）和低强度激光疗法治疗颞下颌关节紊乱病患者的有效性。材料与方法：对60例诊断为多种病因所致颞下颌关节紊乱病的患者进行了临床试验。所有患者在连续6周内接受了两种治疗方法。采用配对t检验来验证结果的显著性。结果：观察到两种疗法在活动范围和疼痛缓解方面均有显著改善。
比较分析这两种方法后，低强度激光疗法（LLLT）后获得的值显著高于经皮电刺激神经疗法（TENS）后获得的值（P < 0.01）。
