【目的】 观察基于弓弦力学理论运用针刺结合火龙罐治疗慢性非特异性下腰痛的临床疗效。【方法】 选取2024年1月至 2024年12月深圳平乐骨伤科医院（深圳市坪山区中医院）针灸科收治的80例明确诊断为慢性非特异性下腰痛的患者为研究对 象。按随机数字表将患者随机分为观察组和对照组，每组各40例。对照组给予常规针刺治疗，观察组在对照组治疗的基础 上，联合火龙罐治疗。连续治疗2周，并于治疗后3个月进行随访。治疗2周后，评价2组临床疗效。观察2组患者治疗前后 疼痛视觉模拟量表（VAS）评分、改良版Oswestry功能障碍评分表（ODI）评分的变化情况，以及血清白细胞介素6（IL-6）、肿瘤 坏死因子α（TNF-α）水平的情况。比较2组患者治疗前后腰椎前屈、后伸、侧屈及旋转活动度的变化情况，以及腰椎屈肌和 伸肌耐力时间的情况。【结果】（1）观察组总有效率为97.50%（39/40），对照组为82.50%（33/40）。观察组疗效优于对照组，差 异有统计学意义（P＜0.05）。（2）治疗后及治疗后 3个月随访，2组患者的 VAS评分、ODI评分均明显改善（P＜0.05），且观察 组在改善VAS评分、ODI评分方面明显优于对照组，差异有统计学意义（P＜0.05）。（3）治疗后及治疗后3个月随访，2组患者 的IL-6、TNF-α水平明显下降（P＜0.05），且观察组在改善IL-6、TNF-α水平方面明显优于对照组，差异有统计学意义（P＜ 0.05）。（4）治疗后及治疗后 3个月随访，2组患者的腰椎前屈、后伸、侧屈、旋转活动度均明显改善（P＜0.05），且观察组在 改善腰椎活动度方面明显优于对照组，差异有统计学意义（P＜0.05）。（5）治疗后及治疗后3个月随访，2组患者的腰椎屈肌耐 力时间、腰椎伸肌耐力时间均明显改善（P＜0.05），且观察组在改善腰椎屈肌耐力时间、腰椎伸肌耐力时间方面明显优于对 照组，差异有统计学意义（P＜0.05）。【结论】 基于弓弦力学理论运用针刺结合火龙罐治疗慢性非特异性下腰痛，能明显减轻 患者的疼痛症状，恢复患者的腰椎功能，促进患者的功能康复，疗效显著。

Objective To observe the clinical efficacy of acupuncture combined with Fire Dragon Cupping Therapy in the treatment of chronic non-specific low back pain （CNLBP） based on the bowstring mechanics theory. Methods A total of 80 patients diagnosed with CNLBP and admitted to the Acupuncture Department of Shenzhen Pingle Orthopedic and Traumatology Hospital （Shenzhen Pingshan District Hospital of Traditional Chinese Medicine） from January 2024 to December 2024 were selected as the study subjects. The patients were randomly divided into an observation group and a control group using a random number table，with 40 cases in each group.The control group received conventional acupuncture treatment，while the observation group received Fire Dragon Cupping Therapy in addition to the same acupuncture treatment as the control group. The treatment lasted for 2 weeks， with a follow-up conducted 3 months after treatment. After 2 weeks of treatment， the clinical efficacy of both groups was evaluated. Changes in the Visual Analogue Scale （VAS） score，modified Oswestry Disability Index （ODI） score，serum interleukin 6（IL-6） and tumor necrosis factor α（TNF-α） levels were observed before and after treatment. Additionally，changes in lumbar flexion，extension，lateral flexion，and rotation range of motion （ROM）， as well as endurance time of lumbar flexor and extensor muscles， were compared between the two groups. Results （1） The total effective rate was 97.50% （39/40） in the observation group and 82.50% （33/40） in the control group. The efficacy of the observation group was superior to that of the control group，the difference being statistically significant （P＜0.05）.（2） After treatment and at the 3-month follow-up，both groups showed significant improvements in VAS and ODI scores （P＜0.05）， with the observation group demonstrating significantly better improvements than the control group，the differences being statistically significant （P＜0.05）. （3） After treatment and at the 3-month follow-up，serum IL-6 and TNF-α levels significantly decreased in both groups （P＜0.05），with the observation group showing significantly greater reductions than the control group，the differences being statistically significant （P＜0.05）.（4） After treatment and at the 3-month follow-up，lumbar flexion，extension，lateral flexion，and rotation ROM significantly improved in both groups （P＜0.05），with the observation group exhibiting significantly better improvements than the control group， the difference being statistically significant （P＜0.05）.（5） After treatment and at the 3-month follow-up，lumbar flexor and extensor muscle endurance time significantly improved in both groups （P＜0.05），with the observation group demonstrating significantly better improvements than the control group，the difference being statistically significant （P＜0.05）. Conclusion The combination of acupuncture and Fire Dragon Cupping Therapy based on the bowstring mechanics theory can significantly alleviate pain，restore lumbar function，and promote functional recovery in patients with CNLBP，demonstrating notable clinical efficacy.
