To analyse the effects of dry needling (DN) in upper trapezius latent trigger points (LTrPs) on pressure pain threshold (PPT) and surface electromyography (sEMG).
Randomized, double-blind, placebo controlled clinical trial.
Sports Rehabilitation Laboratory, University of Castilla-La Mancha.
Forty-six participants (18-35 years old) with LTrP in the upper trapezius were divided into two groups: DN-group and Sham-DN-group.
In the DN-group, the needle was inserted 10-times through the skin, and it was manipulated up and down using a "fast in and out" technique. In the Sham-DN-group, non-penetrating needles were used.
PPT, sEMG at rest, and sEMG in isometric contraction of the LTrP of the upper trapezius muscle were evaluated at baseline, 30 min after treatment, and after 24 h, and 72 h of follow-up.
The mean change in sEMG at rest between baseline and 30 min was - 0.38 (0.38) %refRMS for the DN group and - 0.05 (0.31) %refRMS for the Sham-DN group (mean difference -0.34, 95% confidence interval (CI) of the difference: - 0.54 to - 0.13), and between baseline and 24 h was - 0.35 (0.35) %refRMS for the DN group and - 0.06 (0.58) %refRMS for the Sham-DN group (mean difference -0.29, 95% CI: -0.57 to -0.01). In addition, the DN-group showed higher values of PPT than the Sham-DN group at 72 h (5.22 (1.23) to 4.65 (1.03) kg/cm; p < 0.05).
A single session of DN intervention was effective in reducing the electromyographic activity, muscle fatigue and pain of the upper trapezius muscle in LTrP.
In healthy volunteers dry needling is effective.
分析在上斜方肌潜伏触发点（LTrP）中进行干针治疗（DN）对压力疼痛阈值（PPT）和表面肌电图（sEMG）的影响。
随机、双盲、安慰剂对照临床试验。
卡斯蒂利亚拉曼查大学运动康复实验室。
46 名年龄在 18-35 岁之间、上斜方肌有 LTrP 的参与者被分为两组：DN 组和 Sham-DN 组。
在 DN 组中，将针穿过皮肤 10 次，并使用“快速进出”技术上下操作。在 Sham-DN 组中，使用非穿透针。
在基线、治疗后 30 分钟、24 小时和 72 小时的随访中，评估上斜方肌 LTrP 的静息 PPT、sEMG 和等长收缩 sEMG。
DN 组在静息时 sEMG 的平均变化从基线到 30 分钟为-0.38（0.38）%refRMS，Sham-DN 组为-0.05（0.31）%refRMS（平均差异-0.34，95%置信区间（CI）差值：-0.54 至-0.13），从基线到 24 小时，DN 组为-0.35（0.35）%refRMS，Sham-DN 组为-0.06（0.58）%refRMS（平均差异-0.29，95%CI：-0.57 至-0.01）。此外，DN 组在 72 小时时的 PPT 值高于 Sham-DN 组（5.22（1.23）至 4.65（1.03）kg/cm；p<0.05）。
单次 DN 干预可有效降低上斜方肌 LTrP 的肌电活动、肌肉疲劳和疼痛。
在健康志愿者中，干针治疗是有效的。
