Neck pain is considered one of the most prevalent global public health problems. This study aimed to compare the immediate and subsequent effects of traditional acupuncture (TA) and laser acupuncture (LA) therapies in individuals with chronic non-specific neck pain. Eighty-four individuals were randomly allocated into 3 groups: TA (needle acupuncture treatment), LA (laser acupuncture treatment: 808 nm; 100 mW; 10 J per point), and S-LA (sham laser acupuncture). The participants were men and women aged between 18 and 60 years who had experienced chronic non-specific neck pain for a minimum period of 3 months. The Tianzhu, Fengchi, Jianjing, and Jianzhongshu acupuncture points were stimulated bilaterally. The primary outcomes were pain intensities at rest and during active neck movements, assessed using the Numerical Rating Scale. The secondary outcomes were Pressure Pain Threshold, Temporal Summation of pain, Conditioned Pain Modulation, and Global Perceived Effect scale. The assessments were performed immediately before and after a single treatment session. Additionally, determinations of pain intensity at rest and Global Perceived Effect were performed in a follow-up assessment one month after the interventions. The results showed that the TA and LA interventions were equally significantly superior in reducing immediate pain compared to placebo laser acupuncture (p = 0.001). Traditional acupuncture and laser acupuncture provided equally effective reductions of pain intensity in patients with chronic non-specific neck pain.

颈部疼痛被认为是全球最普遍的公共卫生问题之一。本研究旨在比较传统针刺疗法（TA）和激光针刺疗法（LA）对慢性非特异性颈部疼痛患者的即时和后续影响。84名个体被随机分为3组：TA组（针刺治疗）、LA组（激光针刺治疗：808nm；100mW；每穴10J）和假激光针刺组（S-LA）。参与者为年龄在18至60岁之间、经历慢性非特异性颈部疼痛至少3个月的男性和女性。双侧刺激天柱、风池、肩井和肩中俞穴位。主要结局指标是静息时和颈部主动活动时的疼痛强度，采用数字评定量表进行评估。次要结局指标是压痛阈值、疼痛的时间总和、条件性疼痛调制和整体感觉效果量表。评估在单次治疗前后立即进行。此外，在干预后1个月的随访评估中测定静息时的疼痛强度和整体感觉效果。结果表明，与假激光针刺相比，TA和LA干预在减轻即时疼痛方面均具有同等显著的优越性（p = 0.001）。传统针刺和激光针刺在减轻慢性非特异性颈部疼痛患者的疼痛强度方面同样有效。临床试验注册：RBR-7vbw5gd（巴西临床试验注册中心 - ReBEC）。
