Low back pain (LBP) can significantly affect a person's quality of life. Cupping has been used to treat LBP. However, various cupping methods are typically included in evaluating the efficacy of cupping therapy. Therefore, the objectives of this study were to evaluate the evidence from the literature regarding the effects of dry and wet cupping therapy on LBP in adults. Dry and wet cupping therapy are analyzed categorically in this study.
We searched for randomized clinical trials with cupping in LBP published between 2008 and 2022. In dry or wet cupping clinical studies, pain intensity was assessed using the Visual Analogue Scale and present pain intensity, and the quality of life intensity was measured using the Oswestry disability index.
The 656 studies were identified, of which 10 studies for 690 patients with LBP were included in the meta-analysis. There was a significant reduction in the pain intensity score with present pain intensity using wet cupping therapy (P < .01). In addition, both cupping therapy groups displayed significant Oswestry disability index score reduction compared to the control group (both P < .01). The patients with LBP have a substantial reduction by using wet cupping but have not shown a considerable decrease by using dry cupping (P = .19). In addition, only wet cupping therapy groups displayed a significantly improved quality of life compared to the control group. The study had a very high heterogeneity (I2 > 50%). It means there is no standardization in the treatment protocol in randomized clinical trials. In the meta-regression, there was statistically significant evidence that the number of treatment times and intercepts were related (P < .01).
The present meta-analysis shows that wet cupping therapy effectively reduces the pain intensity of LBP. Furthermore, both dry wet cupping therapy improved patients with LBP quality of life.
腰痛（LBP）会显著影响个人的生活质量。拔罐疗法已被用于治疗 LBP。然而，在评估拔罐疗法的疗效时，通常会包含各种拔罐方法。因此，本研究旨在评估文献中关于干、湿拔罐疗法治疗成人 LBP 的疗效证据。本研究对干、湿拔罐疗法进行了分类分析。
我们检索了 2008 年至 2022 年间发表的关于 LBP 拔罐治疗的随机对照临床试验。在干或湿拔罐的临床研究中，使用视觉模拟评分法评估疼痛强度，使用 Oswestry 残疾指数评估当前疼痛强度和生活质量强度。
共确定了 656 项研究，其中纳入了 10 项研究的 690 例 LBP 患者进行荟萃分析。湿拔罐疗法可显著降低当前疼痛强度的疼痛强度评分（P<.01）。此外，与对照组相比，两组拔罐治疗组的 Oswestry 残疾指数评分均显著降低（均 P<.01）。LBP 患者使用湿拔罐疗法有明显改善，但使用干拔罐疗法没有明显改善（P=.19）。此外，只有湿拔罐疗法组与对照组相比，生活质量有显著改善。该研究存在很高的异质性（I2>50%）。这意味着在随机临床试验中治疗方案没有标准化。在元回归中，有统计学意义的证据表明治疗次数和截距之间存在关联（P<.01）。
本荟萃分析表明，湿拔罐疗法能有效减轻 LBP 的疼痛强度。此外，干、湿拔罐疗法均能改善 LBP 患者的生活质量。
