This research was designed to study effects of high versus low-level laser therapy (HILT and LLLT) on post-dry needling soreness (PNS) at patients with chronic neck pain. We also studied effects of HLLT or LLLT application plus dry needling (DN) on pain, range of motion (ROM), and neck disability index (NDI) at the identified patients. This is a clinical trial in 48 women with chronic neck pain aged 18-35 who were divided into three groups: HLLT, LLLT, and placebo group. All the participants received one session of DN and laser therapy. The study assessed the soreness using Visual Analog Scale for needle pain (nVAS) and Pressure Pain Threshold (PPT) before, immediately after, 24 and 48 h after laser therapy. Pain, ROM, and NDI assessed before and also different time courses after DN plus laser therapy. PPT and nVAS improved in all groups over time. In the placebo group, nVAS increased significantly (p < 0.001) after treatment. VAS, NDI, and ROM improved 48 h after treatment in all groups. The VAS scores were substantially decreased (p < 0.001) immediately after treatment for LLLT group and also 24 h after treatment for both LLLT and HLLT groups. LLLT and HLLT might prevent immediately increasing the PNS. Adding one session of LLLT or HLLT to DN could effectively eliminate the neck pain at 24 h. All groups improved NDI and ROM the same.

本研究旨在探讨高剂量与低剂量激光疗法（HILT和LLLT）对慢性颈部疼痛患者干针治疗后疼痛（PNS）的影响。我们还研究了HLLT或LLLT联合干针治疗（DN）对确诊患者的疼痛、活动范围（ROM）和颈部功能障碍指数（NDI）的影响。这是一项针对48名年龄在18 - 35岁的慢性颈部疼痛女性的临床试验，她们被分为三组：HLLT组、LLLT组和安慰剂组。所有参与者均接受了一次DN和激光治疗。该研究在激光治疗前、治疗后即刻、治疗后24小时和48小时使用针刺痛觉视觉模拟量表（nVAS）和压力疼痛阈值（PPT）评估疼痛程度。在DN加激光治疗前以及治疗后的不同时间点评估疼痛、ROM和NDI。随着时间的推移，所有组的PPT和nVAS均有所改善。在安慰剂组中，治疗后nVAS显著增加（p < 0.001）。所有组在治疗后48小时VAS、NDI和ROM均有所改善。LLLT组治疗后即刻VAS评分大幅下降（p < 0.001），LLLT组和HLLT组治疗后24小时VAS评分也大幅下降。LLLT和HLLT可能会立即阻止PNS的增加。在DN基础上加一次LLLT或HLLT可在24小时有效消除颈部疼痛。所有组的NDI和ROM改善情况相同。注册号：IRCT20190411043241N1。于2019年9月2日注册。
