【目的】 观察基于“枢机”理论运用毫火针针刺激痛点治疗颈肩肌筋膜疼痛综合征（MPS）的临床疗效。【方法】 选取 2023年1月至2023年9月广州中医药大学东莞医院针灸科病房及门诊收治的64例明确诊断为颈肩MPS的患者作为研究对象， 按随机数字表将患者随机分为对照组和观察组，每组各32例。对照组给予塞来昔布胶囊口服，观察组在对照组治疗的基础 上，给予毫火针治疗。1 周为 1 个疗程，共治疗 2 个疗程。治疗 2 周后，评价 2 组临床疗效，观察 2 组患者治疗前后简化 McGill疼痛问卷（SF-MPQ）评分的变化情况，以及颈椎功能障碍指数（NDI）评分的情况。比较2组患者治疗前后颈椎关节活动 度的变化情况。【结果】（1）治疗后，2组患者的SF-MPQ评分明显改善（P＜0.05），且观察组在改善SF-MPQ评分方面明显优 于对照组，差异有统计学意义（P＜0.05）。（2）治疗后，2组患者的NDI评分明显改善（P＜0.05），且观察组在改善NDI评分方 面明显优于对照组，差异有统计学意义（P＜0.05）。（3）治疗后，2组患者的颈椎关节活动度明显改善（P＜0.05），且观察组在 改善颈椎关节活动度方面明显优于对照组，差异有统计学意义（P＜0.05）。（4）观察组总有效率为 96.88%（31/32），对照组为 84.38%（27/32）。观察组疗效优于对照组，差异有统计学意义（P＜0.05）。【结论】 基于“枢机”理论运用毫火针针刺激痛点治 疗颈肩肌MPS，可明显改善患者的疼痛症状，改善患者的肩颈软组织损伤情况，并提高患者的颈肩活动度，疗效显著。

Objective To observe the clinical efficacy of filiform-heated needle stimulation on myofascial trigger points（MTrPs） based on the “pivot mechanism” theory in treating neck-shoulder myofascial pain syndrome（MPS）. Methods Sixty-four patients diagnosed with neck-shoulder MPS from the Acupuncture Department（inpatient and outpatient） of Guangzhou University of Chinese Medicine Dongguan Hospital between January 2023 and September 2023 were selected and randomly divided into a control group and an observation group using a random number table，with 32 cases per group. The control group received oral administration of Celecoxib Capsules，while the observation group received additional filiform-heated needle therapy. The treatment duration was 2 weeks and 1 course per week. Clinical efficacy was evaluated after 2 weeks，with observing the changes in the Short-Form McGill Pain Questionnaire（SF-MPQ） scores，Neck Disability Index（NDI） scores. The cervical range of motion（ROM） was compared between the two groups. Results （1） After treatment，the SF-MPQ scores of the two groups of patients were significantly improved（P＜0.05），and the observation group was significantly superior to the control group in improving the SF-MPQ scores，and the difference was statistically significant（P＜0.05）.（2） After treatment，the NDI scores of patients in the two groups were significantly improved（P＜0.05），and the observation group was significantly superior to the control group in improving the NDI scores， and the difference was statistically significant（P＜0.05）. （3） After treatment， the cervical joint mobility of patients in the two groups was significantly improved（P＜0.05）， and the observation group was significantly superior to the control group in improving cervical joint mobility，with a statistically significant difference（P＜0.05）.（4） The total effective rate was 96.88%（31/32） in the observation group and 84.38%（27/32） in the control group. The efficacy of the observation group was superior to that of the control group，and the difference was statistically significant（P＜0.05）. Conclusion Filiform-heated needle stimulation on MTrPs based on the “pivot mechanism” theory significantly alleviates pain，improves soft tissue injury，and enhances neck-shoulder mobility in patients with neck-shoulder MPS，demonstrating remarkable clinical efficacy.
