The efficacy of manual therapy (Chuna) for chronic obstructive pulmonary disease: Protocol for a systematic review

Chronic obstructive pulmonary disease (COPD) is a challenging disease whose prevalence has increased over the last decades. Non-pharmacological therapies such as pulmonary rehabilitation occupy a core position in patient management. Among these therapies, manual therapy reduces symptoms and increases exercise capacity targeting musculoskeletal problems. Chuna, a traditional Korean manual therapy, has improved pulmonary disorders in clinical practice but unfortunately has not had its effects reported. This systematic review aims to evaluate the effectiveness and safety of manual therapy, focused on the use of Chuna in the management of COPD patients.

The following databases will be used in this study: MEDLINE via PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Database (CNKI), KoreaMed, Korean Medical Database (KMbase), and Oriental Medicine Advanced Searching Integrated System (OASIS). The primary outcome comprises lung function and exercise capacity. Secondary outcomes included symptoms, quality of life, and adverse events. We will include randomized controlled trials (RCTs) and crossover studies. Two independent reviewers will screen the searched studies, determine if they are suitable for inclusion, and perform data extraction. The risk of bias will be assessed using the Cochrane risk of bias tool. When appropriate, data will be pooled across studies for meta-analysis using a fixed or random effects model. When quantitative synthesis is not appropriate, the evidence will be summarized qualitatively.

This study will provide a comprehensive review of the available evidence to assess the efficacy of Chuna for COPD patients. Results will be published in a peer-reviewed journal and disseminated electronically and in print.

This study will provide high-quality current evidence for evaluation the efficacy of Chuna for patients with COPD. Clinicians, patients and policy makers may find this review useful in making decisions regarding the use of Chuna for patients with COPD.
