The effectiveness and safety of Chuna manual therapy on scoliosis: A protocol for systematic review and meta-analysis

Background: Scoliosis is a spinal deformity and is diagnosed as Cobb angle being greater than 10°. Because it is accompanied with structural dysfunction, it can cause pain, worsen the patient's general health and quality of life. The prevalence of scoliosis has been increasing and many treatments, including surgical treatment and conservative treatment, such as observation, bracing, physiotherapy, and Chuna manual therapy (CMT), have been suggested. CMT is a manual therapy in Korean medicine that provides effective stimulation to the patient's body structure to treat structural dysfunction. After Korean national health insurance's coverage of CMT in 2019, the application of CMT for scoliosis has increased, and many studies have been reported. There have been attempts to elucidate the effectiveness of CMT on scoliosis; however, its effectiveness still remains unconfirmed. Therefore, the aim of this study is to evaluate the effectiveness and safety of CMT on scoliosis. Methods: The published randomized controlled trials that evaluated the effectiveness and safety of CMT for scoliosis will be searched for in multiple electronic databases without the limitation of country and language. Data on characteristics of studies, interventions, comparators, outcome measures, results, and information for assessment of study quality will be extracted. The primary outcome will be the Cobb angle and the secondary outcomes will be the scales of pain, function, quality of life and disability, and adverse events. Data synthesis and analysis will be conducted using the Review Manager software for Windows (RevMan ver. 5.3.; Copenhagen; The Nordic Cochrane Center, The Cochrane Collaboration, 2014). Subgroup analysis to identify the differences between different CMT maneuvers will also be performed. For risk of bias assessment, the “risk of bias” tool from Cochrane Collaboration will be used. Results: This study will present the clinical evidence on the effectiveness and safety of CMT on scoliosis. Conclusion: This study will propose useful evidence for treatment, further research, and health policies in the future.
