Background: Exercise training is key to the comprehensive management of patients with chronic obstructive pulmonary disease (COPD). Creative dance can be an innovative approach as effective as traditional exercise training., Objectives: This study aimed to investigate effect of creative dance-based exercise (CDE) training on functional capacity, postural stability and balance, pulmonary and cognitive functions, respiratory and peripheral muscle strength in COPD patients., Methods: Twenty-four patients with COPD were randomly allocated to either "chest physiotherapy and home-based walking program" (PT) or "CDE alongside home-based chest physiotherapy group" (PT+CDE). Both groups performed chest PT program twice a day for 5 days per week for 8 weeks. PT+CDE group received CDE training 2 days a week for 8 weeks. Primary outcome was six minute walk test (6MWT). Secondary outcomes were postural stability and balance, pulmonary function, maximum inspiratory (MIP) and expiratory (MEP) pressure, peripheral muscle strength, Montreal Cognitive Assessment (MoCA), COPD Assessment Test (CAT), and BODE index. Outcome measures were assessed at baseline and after 8 weeks of training., Results: Both groups showed statistically significant improvements in 6MWT distance, MIP, MEP, MoCA score, CAT, and BODE index (p < 0.05). Only with CDE training was achieved improvements in postural stability and balance scores, pulmonary function, and peripheral muscle strength (p < 0.05). The improvements in 6 MWT distance, MEP, MoCA score, and CAT were greater in PT+CDE group (p < 0.05)., Conclusion: Use of creative dance training in addition to home-based chest PT program was more effective than chest PT program regarding primary and secondary outcomes in COPD patients., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Inc.

Background: Similar to six-minute walk test (6MWT), sit-to-stand test (STST) is a self-paced test which elicits sub-maximal effort; therefore, it is suggested as an alternative measurement for functional exercise capacity in various pulmonary conditions including COPD and cystic fibrosis. We aimed to investigate the association between 30-second STST (30s-STST) and 6MWT in both children with bronchiectasis (BE) and their healthy counterparts, as well as exploring cardiorespiratory burden and discriminative properties of both tests., Methods: Sixty children (6 to 18-year-old) diagnosed with non-cystic fibrosis BE and 20 age-matched healthy controls were included. Both groups performed 30s-STST and 6MWT. Test results, and heart rate, SpO 2 and dyspnea responses to tests were recorded., Results: Univariate analysis revealed that 30s-STST was able to explain 52% of variance in 6MWT (r = 0.718, p<0.001) in BE group, whereas 20% of variance in healthy controls (r = 0.453, p = 0.045). 6MWT elicited higher changes in heart rate and dyspnea level compared to 30s-STST, indicating it was more physically demanding. Both 30s-STST (21.65±5.28 vs 26.55±3.56 repetitions) and 6MWT (538±85 vs 596±54 m) were significantly lower in BE group compared to healthy controls (p<0.01). Receiver operating characteristic (ROC) curve analysis revealed an area under the ROC curve (UAC) of 0.765 for 30s-STST and 0.693 for 6MWT in identifying the individuals with or without BE (p<0.05). Comparison between AUCs of 30s-STST and 6MWT yielded no significant difference (p = 0.466), indicating both tests had similar discriminative properties., Conclusions: 30s-STST is found to be a valid alternative measurement for functional exercise capacity in children with BE., (Copyright © 2020 Elsevier Inc.
