- Elastic tape reduces dyspnea and improves health status in the short term in nonobese COPD males: A randomized controlled trial(2024) SANTOS, Eloise Arruda dos; PINTO, Thiago Fernandes; XAVIER, Rafaella Fagundes; STELMACH, Rafael; CARVALHO-PINTO, Regina Maria; CARVALHO, Celso Ricardo Fernandes deIntroduction and objectives: The elastic tape (ET) is a novel intervention that acutely improves exercise capacity in laboratory tests; however, its effect on a patient's daily life remains unknown. This randomized controlled trial evaluated the effects of ET on daily life physical activity (DLPA), dyspnea symptoms, health status, and health -related quality of life (HRQoL) in individuals with COPD. Methods: Fifty males with moderate to very severe COPD were randomly assigned to an intervention group (ETG, n = 25), receiving ET on the chest wall and abdomen, or a control group (CG, n = 25). The intervention was for 14 days. DLPA (accelerometry; steps per day, and sedentary time), dyspnea symptoms (transition dyspnea index, TDI; and modified Medical Research Council, mMRC), health status (COPD assessment test, CAT), and health -related quality of life (HRQoL, CRQ) were evaluated at baseline and on Day 21 after the intervention. Results: No change in the DLPA was observed in between-group comparison. CG presented a reduction in step counts after 21days (-707,p <0.05) while ETG. maintained (-114,p > 0.94). However, ET reduced dyspnea symptoms in all TDI domains (functional, task, and effort) and on the mMRC scale after 14 days compared with CG (p < 0.01). Also, the ETG improved CAT score compared to the CG, reaching minimal clinical important difference (MCID) (-4.4 score, p <0.01). The ETG also improved in most CRQ domains reaching MCID after 21 days. Conclusions: ET does not modify DLPA but reduces dyspnea and improves health status and HRQoL in nonobese males with moderate to very severe COPD in the short term. This novel and low-cost intervention improves COPD symptoms.
- Identification of functional phenotypes in people with COPD: influence of postural balance, physical activity, sedentary behaviour and quadriceps muscle strength(2019) XAVIER, Rafaella; CAPORALI, Ana Carolina; LOPES, Aline; OLIVEIRA, Cristino; FERNANDES, Frederico; STELMACH, Rafael; PINTO, Regina Carvalho; CUKIER, Alberto; CARVALHO, Celso
- Effects of a behaviour change intervention aimed at increasing physical activity on clinical control of adults with asthma: study protocol for a randomised controlled trial(2019) FREITAS, Patricia D.; XAVIER, Rafaella F.; PASSOS, Natalia F. P.; CARVALHO-PINTO, Regina M.; CUKIER, Alberto; MARTINS, Milton A.; CAVALHERI, Vinicius; HILL, Kylie; STELMACH, Rafael; CARVALHO, Celso R. F.Background: In adults with asthma, physical activity has been associated with several asthma outcomes. However, it is unclear whether changes in physical activity, measured via an accelerometer, have an effect on asthma control. The objective of the present study is, in adults with moderate-to-severe asthma, to investigate the effects of a behaviour change intervention, which aims to increase participation in physical activity, on asthma clinical control. Methods: This is a single-blind (outcome assessor), two-arm, randomised controlled trial (RCT). Fifty-five participants with moderate-to-severe asthma, receiving optimized pharmacological treatment, will be randomly assigned (computer-generated) into either a Control Group (CG) or an Intervention Group (IG). Both groups will receive usual care (pharmacological treatment) and similar educational programmes. In addition to these, participants in the IG will undergo the behaviour change intervention based on feedback, which aims to increase participation in physical activity. This intervention will be delivered over eight sessions as weekly one-on-one, face-to-face 40-min consultations. Both before and following the completion of the intervention period, data will be collected on asthma clinical control, levels of physical activity, health-related quality of life, asthma exacerbation and levels of anxiety and depression symptoms. Anthropometric measurements will also be collected. Information on comorbidities, lung function and the use of asthma medications will be extracted from the participant's medical records. Discussion: If successful, this study will demonstrate that, in adults with asthma, a behavioural change intervention which aims to increase participation in physical activity also affects asthma control.

- The Mini-Balance Evaluation System Test Can Predict Falls in Clinically Stable Outpatients With COPD A 12-MO PROSPECTIVE COHORT STUDY(2019) PEREIRA, Ana Carolina A. C.; XAVIER, Rafaella F.; LOPES, Aline C.; SILVA, Cibele C. B. M. da; OLIVEIRA, Cristino C.; FERNANDES, Frederico L. A.; STELMACH, Rafael; CARVALHO, Celso R. F.Purpose: This study evaluated the accuracy of the Mini-Balance Evaluation System Test (Mini-BESTest) for predicting falls in patients with chronic obstructive pulmonary disease (COPD) and investigated whether postural balance is a risk factor for falls. Methods: Postural balance was evaluated by the Mini-BESTest at baseline, and the incidence of falls over a 12-mo period was prospectively measured by a self-reported falls diary and confirmed by telephone calls. A discriminative power analysis was performed using receiver operating characteristic (ROC) curve and logistic regression analysis. Results: Sixty-seven outpatients with COPD (mean age SD = 67 +/- 9.3 yr) were included. Twenty-five patients (37.3%) experienced 1 fall, and 28.2% of the falls resulted in injuries. The Mini-BESTest predicted falls in patients with COPD at the 6- and 12-mo follow-ups with a cut-off score of 22.5 (area under the curve = 0.85 and 0.87) with good sensitivity and specificity (85.7% and 66.7%; 84% and 73.8%, respectively). Higher scores on the Mini-BESTest were associated with a lower risk of falls at 12 mo (OR = 0.50; 95% CI, 0.36-0.70; P < .001). Conclusions: Postural balance assessed by the Mini-BESTest is a good predictor of falls in patients with COPD. Our results imply that impaired balance contributes to the risk of falling and that balance training and fall prevention programs may be required for this population.
