Dry needling (DN) is a widely used in treatment of myofascial trigger points (MTrPs). The purpose of this pretest-posttest clinical trial was to investigate the neurophysiological and clinical effects of DN in patients with MTrPs.
A sample of 20 patients (3 man, 17 women; mean age 31.7 ± 10.8) with upper trapezius MTrPs received one session of deep DN. The outcomes of neuromuscular junction response (NMJR), sympathetic skin response (SSR), pain intensity (PI) and pressure pain threshold (PPT) were measured at baseline and immediately after DN.
There were significant improvements in SSR latency and amplitude, pain, and PPT after DN. The NMJR decreased and returned to normal after DN.
A single session of DN to the active upper trapezius MTrP was effective in improving pain, PPT, NMJR, and SSR in patients with myofascial trigger points. Further studies are needed.
干针疗法（DN）广泛应用于肌筋膜触发点（MTrP）的治疗。这项前后测临床试验的目的是研究干针疗法对患有肌筋膜触发点的患者的神经生理学和临床效果。
选取20例患有上斜方肌肌筋膜触发点的患者（3名男性，17名女性；平均年龄31.7±10.8岁）接受一次深层干针治疗。在基线期和干针治疗后即刻测量神经肌肉接头反应（NMJR）、交感神经皮肤反应（SSR）、疼痛强度（PI）和压痛阈（PPT）。
干针治疗后，SSR潜伏期和波幅、疼痛及PPT均有显著改善。干针治疗后NMJR降低并恢复正常。
对活跃的上斜方肌肌筋膜触发点进行单次干针治疗可有效改善肌筋膜触发点患者的疼痛、PPT、NMJR和SSR。需要进一步研究。
