Abstract

AIMS To study the effect and cost-effectiveness of jaw exercise treatment in patients with masticatory myofascial pain. METHODS A total of 97 patients with myofascial pain according to the RDC/TMD were randomized into three groups: (1) jaw exercises; (2) stabilization appliance; or (3) no treatment. After 3 months, the patients were evaluated according to the following instruments: pain intensity according to a visual analog scale (VAS); global improvement according to the Patient Global Impression of Change scale (PGIC); depression and anxiety according to the Hospital Anxiety and Depression Scale (HADS); jaw function according to the Jaw Functional Limitation Scale (JFLS-20); consumption of analgesics; and frequency of tension-type headache. RESULTS Pain intensity during jaw movement decreased significantly more in the jaw exercise group compared to the no treatment group (P < .001). There was no statistically significant difference between the jaw exercise and stabilization appliance groups in this aspect. The patients in the treatment groups reported greater improvement on the PGIC compared to the no treatment group (P < .001). There was a significant decrease in headache frequency (P = .028), consumption of analgesics (P = .007), and JFLS scores (P = .008) in the jaw exercise group compared to the no treatment group. In the jaw exercise group, patients had fewer appointments and a lower mean treatment time compared to the group that received stabilization appliance treatment. CONCLUSION Jaw exercises are effective in reducing pain intensity, headache, and consumption of analgesics in patients with masticatory myofascial pain. Jaw exercises are also cost-effective when compared to treatment with a stabilization appliance.

治疗性下颌运动治疗咀嚼肌筋膜疼痛的效果:一项随机对照研究。

目的:探讨下颌运动治疗咀嚼肌筋膜疼痛的效果及成本-效果。方法:根据RDC/TMD将97例肌筋膜疼痛患者随机分为3组:(1)颌部锻炼;(二)稳定装置;或(3)不治疗。3个月后，根据以下工具对患者进行评估:根据视觉模拟量表(VAS)评估疼痛强度;根据患者整体印象变化量表(PGIC)进行整体改善;根据医院焦虑和抑郁量表(HADS)进行抑郁和焦虑;颌骨功能限制量表(JFLS-20);镇痛药的使用;紧张性头痛的频率。结果:与未治疗组相比，下颌运动组下颌运动时疼痛强度明显降低(P < 0.001)。在这方面，下颌运动组和稳定矫治器组之间无统计学差异。与未治疗组相比，治疗组患者PGIC的改善更大(P < 0.001)。与未治疗组相比，下颌运动组的头痛频率(P = 0.028)、止痛药用量(P = 0.007)和JFLS评分(P = 0.008)均显著降低。与接受稳定矫治器治疗的组相比，下颌运动组患者预约次数更少，平均治疗时间更短。结论:下颌运动可有效减轻咀嚼肌筋膜疼痛患者的疼痛强度、头痛和镇痛药的消耗。与稳定器械治疗相比，下颌运动也具有成本效益。
