平衡针法治疗膝骨关节炎的即时步态分析研究

目的:观察平衡针法对膝骨关节炎(KOA)患者即时步态的影响,并探讨其作用机制。方法:纳入70例膝骨关节炎患者,随机分为治疗组和对照组,每组各35例。治疗组采用平衡针法治疗,对照组采用普通针刺法治疗。治疗前及治疗后即刻进行步态测试,比较两组患者的疼痛视觉模拟量表(VAS)评分、步长、步速及膝关节内收力矩(EKAM)的变化。结果:治疗后,两组患者的VAS评分均明显降低(P0.05),且治疗组患者的评分低于对照组(P0.05)。治疗后,两组患者的步长、步速均明显增加(P0.05),EKAM峰值明显降低(P0.05);且治疗组患者的步长、步速均高于对照组(P0.05),EKAM峰值低于对照组(P0.05)。结论:平衡针法治疗膝骨关节炎能够较好地改善患者的疼痛症状,其机制可能与降低步态中的膝关节内收力矩有关。

Study of real-time gait analysis on balancing acupuncture in the treatment of knee osteoarthritis

  Objective: To observe the effects of balancing acupuncture on the real-time gait of patients with knee osteoarthritis (KOA) and explore its mechanism.   Methods: Seventy patients with KOA were included and randomly divided into the treatment group and control group, 35 cases in each group. The patients in the treatment group were treated with balancing acupuncture, and the patients in the control group were treated with the common acupuncture. Gait analysis were performed before and immediately after treatment, and the score of visual analogue scale (VAS), stride length, stride speed, and external knee adduction moment (EKAM) were compared between the two groups.   Results: After treatment, the VAS scores of the two groups were significantly decreased (P<0.05), and the score of the treatment group was lower than that of the control group (P<0.05). After treatment, the stride length and stride speed of the two groups were significantly increased (P<0.05), and the peak of EKAM was significantly decreased (P<0.05); the stride length and stride speed of the treatment group were higher than those of the control group (P<0.05), and the peak of EKAM of the treatment group was lower than that of the control group (P<0.05).   Conclusion: Balancing acupuncture can better relieve the pain of the patients in the treatment of knee osteoarthritis, and its mechanism may be related to the reduction of knee adduction moment in gait.
