To evaluate the effect of a rapid treatment protocol of low-level laser therapy (LLLT) in patients with myofascial pain and mouth opening limitation.
Twenty patients were randomly allocated into the laser group (LG) (n = 10) and the placebo group (PG) (n = 10). Two LLLT sessions or placebo were performed. They were applied to the pain points upon palpation, with a 48-hr interval. Patients were evaluated for spontaneous pain sensitivity during mandibular movements and for oral health-related quality of life, which was assessed using the Oral Health Impact Profile for Temporomandibular Disorders (OHIP/TMD) questionnaire.
Two patients from the placebo group were lost during the study. A significant increase in the maximum mouth opening ( = 0.04) and improvement in OHIP/TMD scores ( = 0.003) were observed in the LG after 30 days.
Spontaneous pain was reduced in both groups with low-level laser therapy.
评估肌筋膜疼痛和张口受限患者接受低水平激光治疗（LLLT）快速治疗方案的效果。
将 20 名患者随机分为激光组（LG）（n=10）和安慰剂组（PG）（n=10）。两组均进行两次 LLLT 或安慰剂治疗。将激光或安慰剂应用于触诊时的痛点，间隔 48 小时。在进行下颌运动时评估患者的自发性疼痛敏感度，并使用颞下颌关节紊乱病口腔健康影响量表（OHIP/TMD）评估口腔健康相关生活质量。
安慰剂组有 2 名患者在研究过程中脱落。LG 在 30 天后的最大张口度（ =0.04）和 OHIP/TMD 评分（ =0.003）显著增加。
两组患者的自发性疼痛均在接受低水平激光治疗后减轻。
