To compare the short- and long-term effectiveness of a prefabricated occlusal appliance with that of a stabilization appliance when treating headache in patients with myofascial pain.
Sixty-six patients, 94% of whom suffered concomitantly from headache, at two centres for Stomatognathic Physiology in Sweden and Finland were included in a randomized controlled trial. History questionnaires and clinical examination according to the Research Diagnostic Criteria for Temporomandibular Disorders were used at baseline and at 10-week and 6- and 12-month follow-ups. Patients were randomly assigned to either a prefabricated (R) or a stabilization appliance (S) group.
There were significant decreases in the frequency and intensity of headache in both groups at all follow-ups, without statistically significant differences between groups. At baseline, 23 patients in both groups reported recurrent-continuous headache and, at 12 months, seven in the R group and four in the S group. The mean intensity (numeric rating scale) of headache prior to treatment decreased significantly at 12 months from 5.3 to 2.1 in the R group and from 6.1 to 2.9 in the S group. At the 12-month follow-up, 56% of patients in the R group reported a 30% reduction in intensity of headache and 50% a 50% reduction. In the S group, corresponding values were 39% and 36%, respectively. Non-specific physical symptoms were significantly associated with frequency of headache at baseline and at 6 months, and with depression at 6 and 12 months.
The effectiveness of the prefabricated appliance seems to be similar to that of the stabilization appliance in the treatment of headache in patients with myofascial pain in both the short and long term.
比较预制咬合矫治器与稳定器治疗肌筋膜疼痛患者头痛的短期和长期疗效。
在瑞典和芬兰的两个口腔生理学中心，66 名患者（94%同时患有头痛）参与了一项随机对照试验。在基线、10 周、6 个月和 12 个月随访时，使用病史问卷和根据《颞下颌关节紊乱研究诊断标准》进行临床检查。患者被随机分配到预制（R）或稳定器（S）组。
两组患者在所有随访中头痛的频率和强度均显著下降，组间无统计学差异。基线时，两组各有 23 例患者报告反复发作性持续性头痛，12 个月时 R 组 7 例，S 组 4 例。治疗前头痛的平均强度（数字评分量表）在 R 组从 12 个月时的 5.3 显著下降至 2.1，S 组从 6.1 显著下降至 2.9。在 12 个月随访时，R 组 56%的患者报告头痛强度降低 30%，50%的患者报告头痛强度降低 50%。S 组分别为 39%和 36%。非特异性躯体症状与基线和 6 个月时头痛频率以及 6 和 12 个月时抑郁显著相关。
在治疗肌筋膜疼痛患者的头痛方面，预制矫治器的短期和长期疗效似乎与稳定器相似。
