To investigate the remote effect of dry needling on the irritability of a myofascial trigger point in the upper trapezius muscle.
Thirty-five patients with active myofascial trigger points in upper trapezius muscles were randomly divided into two groups: 18 patients in the control group received sham needling, and 17 patients in the dry-needling group received dry needling into the myofascial trigger point in the extensor carpi radialis longus muscle. The subjective pain intensity, pressure pain threshold, and range of motion of the neck were assessed before and immediately after the treatment.
Immediately after dry needling in the experimental group, the mean pain intensity was significantly reduced, but the mean pressure threshold and the mean range of motion of cervical spine were significantly increased. There were significantly larger changes in all three parameters of measurement in the dry-needling group than that in the control group.
This study demonstrated the remote effectiveness of dry needling. Dry needling of a distal myofascial trigger point can provide a remote effect to reduce the irritability of a proximal myofascial trigger point.
探讨干针疗法对斜方肌上束肌筋膜触发点激惹性的远隔效应。
35 例斜方肌上束活动性肌筋膜触发点患者随机分为两组：18 例对照组接受假针刺，17 例干针组将干针针刺至伸腕长肌的肌筋膜触发点。在治疗前后评估颈痛的主观疼痛强度、压痛阈和颈部活动范围。
干针组治疗后即刻，平均疼痛强度明显降低，而平均压痛阈和颈椎活动度明显增加。干针组三个测量参数的变化均明显大于对照组。
本研究证实了干针疗法的远隔效应。远端肌筋膜触发点的干针治疗可以提供一种远隔效应，以降低近端肌筋膜触发点的激惹性。
