The impact of chronic obstructive pulmonary disease in patients' lives: The perception of the health professionals.

INTRODUCTION: The perception of health professionals about chronic obstructive pulmonary disease (COPD) has not been thoroughly investigated. OBJECTIVE: To analyze the perception of health professionals about the impact of COPD on the lives of affected individuals. MATERIALS AND METHODS: Qualitative and cross-sectional study with five health professionals: two nurses, two physiotherapists, and one medical doctor. They participated in a focus group (FG) session, with semistructured questions covering: definition of COPD, activities of daily living (ADL), and physical activity of daily living (PADL), as well as the importance of these outcomes in the lives of individuals with COPD. DATA ANALYSIS: The FG was recorded, transcribed, and analyzed according to the content analysis. RESULTS: The FG highlighted four main themes: physical-functional and emotional impairment of individuals, the importance of patient-health professional contact, repercussions of COPD on the patients' physical activity, and strategies for promoting physical activity. Based on the four themes exposed, the health professionals reported that there is a progression in the lives of individuals' with COPD, which is divided into three phases: adaptation, reluctance, and dependence. CONCLUSION: There was a negative perception of the health professionals regarding the functionality and emotion of patients with COPD. Emotional aspects, family support, and architectural structure can positively or negatively influence patients' ADL and PADL. Finally, there was a perception of progression in the life of patients with COPD, since their initial adaptation, evolving to physical and emotional dependence.

Are there differences in muscular activation to maintain balance between individuals with chronic obstructive pulmonary disease and controls?

BACKGROUND: The mechanisms underlying impaired balance in chronic obstructive pulmonary disease (COPD) are poorly understood, which makes it difficult to choose the best therapeutic approaches. Therefore, this study aimed to investigate patterns of muscular activation to maintain balance and its determinants in this population. METHODS: Thirty-three subjects with COPD and 33 controls were assessed by a force platform in four tasks: standing with eyes opened (FHEO) and closed (FHEC); standing on unstable surface (SUS) and one-legged stance (OLS). Electromyographic activity of lower limb, trunk and neck muscles was concomitantly recorded. To asses functional balance, Brief-balance evaluation systems and timed up & go (TUG) tests were applied. Lung function, exercise capacity and muscle force were also assessed. RESULTS: Subjects with COPD presented worse balance and higher scalene activation than controls in OLS (mean difference 23.0 [95%CI 1.7-44.3] %Δ µVRMS; P = 0.034), besides presenting also higher activation of gluteus medius during FHEC task (mean difference 1.5 [95%CI 0.2-2.8] %Δ µVRMS; P = 0.023) and taking longer to complete the TUG (mean difference 0.6 [95%CI 0.1-1.2] seconds; P = 0.042). Exercise capacity and peripheral muscle force were determinants of functional balance (r2 = 0.505), whereas age (OR = 1.24; 95%CI 1.02-1.52) and total lung capacity (OR = 2.42; 95%CI 1.05-5.56) were determinants of static balance. CONCLUSION: Individuals with COPD have worse static and functional balance in comparison with controls, besides presenting higher activation of scalene and gluteus medius during static balance tasks. Exercise capacity and peripheral muscle force emerged as determinants of functional balance, whereas age and lung hyperinflation contributed to poor static balance.
