Outcome data pressure pain threshold.

Background
Manual therapy appears to be effective for the relief of tension-type headache (TTH), just as diacutaneous fibrolysis (DF) has shown to be a beneficial technique for the relief of symptoms in other dysfunctions. However, no studies have evaluated the potential beneficial effect of DF in TTH. The aim of this study is to analyze the effect of three sessions of DF in patients with TTH.
Methods
Randomized controlled trial in 86 subjects (43 intervention/ 43 control group). The headache frequency, the headache intensity, the pressure pain thresholds (PPTs) at trapeziometacarpal joint, upper trapezius, suboccipital, frontal and temporal muscles, parietal sutures and the cervical mobility were measured at baseline, at the end of the third intervention and one-month after the last intervention.
Results
Statistically significant differences with p values <0.05 were observed between groups in favor of the intervention group in the one-month follow-up in the following variables: headache frequency, headache intensity, flexion, extension, right and left side-bending, right and left rotation, PPTs in left trapeziometacarpal joint, right suboccipital muscle, right and left temporal muscle, left frontal muscle and right and left parietal.
Conclusions
DF provides a beneficial effect in reducing headache frequency, relieving pain, and improving cervical mobility in patients with TTH.

背景
手法治疗对紧张型头痛（Tension-type headache, TTH）的缓解似乎具有显著效果，正如经皮纤维松解术（Diacutaneous fibrolysis, DF）已被证实可作为一项有益技术，用于缓解其他功能障碍引发的症状。然而目前尚无研究评估经皮纤维松解术对紧张型头痛患者的潜在获益效果。本研究旨在分析三次经皮纤维松解术治疗对紧张型头痛患者的疗效。

方法
本研究为随机对照试验，共纳入86名受试者（干预组与对照组各43例）。分别在基线状态、第三次干预结束时以及末次干预后1个月，对以下指标进行测量：头痛发作频率、头痛强度、腕掌关节、斜方肌上部、枕下肌、额肌、颞肌、顶骨缝处的压力痛阈（Pressure pain thresholds, PPTs），以及颈椎活动度。

结果
在末次干预后1个月的随访中，两组间存在统计学意义上的显著差异（P<0.05），干预组的表现更优，涉及以下指标：头痛发作频率、头痛强度、颈椎屈曲、伸展、左右侧屈、左右旋转，左侧腕掌关节压力痛阈、右侧枕下肌、双侧颞肌、左侧额肌以及双侧顶骨缝处的压力痛阈。

结论
经皮纤维松解术可有效降低紧张型头痛患者的头痛发作频率、缓解疼痛，并改善其颈椎活动度。
