METHODS: Our research included 30 individuals with nonspecific low back pain; their ages varied from 20 to 45. The participants were divided into two parallel groups using a random process: 15 individuals in group A had acupuncture treatment with a dry needle placed to specified locations on their backs, whereas 15 individuals in group B participated in muscle strengthening and stretching exercises. Both before and after therapy, researchers examined the lumbar range of motion (ROM) in four directions: flexion, extension, bilateral side bending, as well as pain intensity and functional impairment.
RESULTS: We examined the data for normality and covariance homogeneity using the Shapiro-Wilk and Box\'s tests, respectively. The variables of interest that were investigated were compared across various test groups and measurement periods using a 2x2 mixed design-multivariate analysis of variance (MANOVA). We used a significance threshold of 0.05. When comparing the two groups after treatment, it was found that the flexion and extension range of motion increased significantly (p<0.05), while the pain intensity, bending to the right and left, and functional impairment decreased significantly (p<0.05). The results of multiple pairwise comparisons showed a noteworthy difference in pain severity, functional debility, and back ROM between the two groups before and after treatment (p<0.05), with group A showing an advantage over group B after treatment.
CONCLUSIONS: Based on the study results, dry needle acupuncture may be a beneficial modality in treating chronic mechanical low back pain by relieving pain intensity, improving functional debility, and improving ROM.
方法:我们的研究包括30名患有非特异性下腰痛的个体,他们的年龄从20岁到45岁不等。使用随机方法将参与者分为两个平行组:A组中的15个人用干燥的针头放置在背部的指定位置进行针灸治疗,B组15人参加了肌肉强化和伸展运动。治疗前后,研究人员检查了四个方向的腰椎运动范围(ROM):屈曲,扩展,双侧侧弯曲,以及疼痛强度和功能障碍。
结果:我们使用Shapiro-Wilk和Box检验检查数据的正态性和协方差同质性,分别。使用2x2混合设计-多变量方差分析(MANOVA),在各个测试组和测量周期中比较研究的感兴趣变量。我们使用0.05的显著性阈值。两组治疗后比较,发现屈曲和伸展运动范围显着增加(p<0.05),而疼痛的强度,向右和向左弯曲,功能损害显著减少(p<0.05)。多重成对比较结果显示疼痛严重程度有显著差异,功能衰弱,两组治疗前后的背部ROM(p<0.05),治疗后A组优于B组。
结论:根据研究结果,通过缓解疼痛强度,干针针刺可能是治疗慢性机械性腰背痛的有益方式,改善功能衰弱,改进ROM。
