Comparison between Pulmonary Rehabilitation and Dance in Patients with Chronic Obstructive Pulmonary Disease: A Randomized Controlled Clinical Trial.

Although dance is understudied in the context of chronic obstructive pulmonary disease (COPD), it is a physical activity that can improve individuals' psychological state and physical function. The aim of this research was to compare the impact of physical training using dance versus pulmonary rehabilitation (PR) on functional capacity, lung and muscle function, and quality of life (QoL) in COPD patients. This randomized controlled clinical trial involved 11 patients who underwent dance (DG) and 11 patients who underwent PR (PRG). The patients were evaluated using the following assessments: the mMRC scale, the COPD Assessment Test (CAT), the Short Form-36 (SF-36), the Hospital Anxiety and Depression Scale (HADS), spirometry, handgrip strength (HGS), the 1-repetition maximum (1-RM) test, and the 6-minute walk test (6MWT). In the intra-group comparison, the DG showed an increase in 6-minute walking distance (6MWD) (p=0.003), a reduction in the mMRC scale, and an improvement in the SF-36 physical functioning and vitality domains. In the intra-group comparison, the PRG showed an increase in 6MWD (p=0.007), a reduction in the mMRC scale, an increase in HGS, an increase in the 1-RM test, and an improvement in all SF-36 domains. In the comparison between groups, the PRG showed an improvement in QoL in the following domains: general perceptions of health and limitations of physical and emotional roles. In conclusion, for patients with COPD, a dance program has the potential to improve functional capacity, the degree of dyspnea, and QoL. However, when compared to a PR, dance is less effective in addressing muscle dysfunction.
