[Scoping review of acupuncture-moxibustion treatment for non-specific low back pain]

Abstract

This study systematically searched and sorted out randomized controlled trial(RCT) of acupuncture-moxibustion treatment for non-specific low back pain by scoping review, so as to demonstrate the current state of the research evidence and provide a reference point for future clinical research and healthcare decision-making. Eight commonly used Chinese and English databases were searched, and the search time was from the establishment of the databases to July 7, 2023, so as to analyze the characteristics of the current status of the current research through visualization methods. A total of 50 studies were included, including 23 studies in Chinese and 27 studies in English. The overall number of studies showed an increasing trend. The percentage of studies published in Chinese non-core journals was 42.0%. The disease subtypes of interest were mainly chronic non-specific low back pain, accounting for 68.0% of the studies. The sample sizes of the studies were mainly concentrated in the range of 50-100 cases. A total of 15 types of interventions were categorized, with acupuncture interventions being the most studied. Duration of treatment did not exceed one month in 80.0% of the studies. Only 8.0% of the studies used minimal clinical important difference(MCID) as a basis for judgment. The follow-up period was set within 3 months in 28.0% of the studies, and 82.0% of the studies concluded that acupuncture-moxibustion was effective in the treatment of non-specific lower back pain. Adverse events were reported in 20.0% of the studies. The risk of bias in the included studies was dominated by low risk of bias and uncertain risk of bias, with fewer studies focusing on high risks of bias. In most of the studies, acupuncture-moxibustion was significantly more effective than the control group. The research on acupuncture-moxibustion treatment for non-specific low back pain is developing rapidly, but there are still insufficient studies on psychological state, safety, and other indicators, and there are still some studies with uncertain risks of bias, which is not conducive to the generalization and application of the findings. Therefore, future studies should improve and refine these shortcomings.
