Procedures such as dry needling (DN) or percutaneous electrical nerve stimulation (PENS) are commonly proposed for the treatment of myofascial trigger points (MTrP). The aim of the present study is to investigate if PENS is more effective than DN in the short term in subjects with mechanical neck pain. This was an evaluator-blinded randomized controlled trial. Subjects were recruited through announcements and randomly allocated into DN or PENS groups. Pain intensity, disability, pressure pain threshold (PPT), range of motion (ROM), and side-bending strength were measured. The analyses included mixed-model analyses of variance and pairwise comparisons with Bonferroni correction. The final sample was composed of 44 subjects (22 per group). Both groups showed improvements in pain intensity (η = 0.62; < 0.01), disability (η = 0.74; < 0.01), PPT (η = 0.79; < 0.01), and strength (η = 0.37; < 0.01). The PENS group showed greater improvements in disability (mean difference, 3.27; 95% CI, 0.27-6.27) and PPT (mean difference, 0.88-1.35; < 0.01). Mixed results were obtained for ROM. PENS seems to produce greater improvements in PPT and disability in the short term.
诸如干针疗法（DN）或经皮电神经刺激（PENS）等治疗方法通常被推荐用于治疗肌筋膜触发点（MTrP）。本研究的目的是调查在患有机械性颈部疼痛的受试者中，PENS在短期内是否比DN更有效。这是一项评估者盲法随机对照试验。通过公告招募受试者，并将其随机分配到DN组或PENS组。测量疼痛强度、功能障碍、压痛阈值（PPT）、活动范围（ROM）和侧弯力量。分析包括方差的混合模型分析和采用Bonferroni校正的两两比较。最终样本由44名受试者组成（每组22名）。两组在疼痛强度（η = 0.62；<0.01）、功能障碍（η = 0.74；<0.01）、PPT（η = 0.79；<0.01）和力量（η = 0.37；<0.01）方面均有改善。PENS组在功能障碍（平均差异，3.27；95%CI，0.27 - 6.27）和PPT（平均差异，0.88 - 1.35；<0.01）方面有更大改善。ROM的结果不一。PENS似乎在短期内能使PPT和功能障碍有更大改善。
