Barriers associated with reduced physical activity in COPD patients* Barreiras associadas à menor atividade física em portadores de DPOC

摘要: Objective: To evaluate the ability of COPD patients to perform activities daily living (ADL); identify barriers that prevent these individuals from performing ADL; and correlate those with dyspnea severity, six-minute walk test (6MWT), an ADL limitation score. Methods: In healthy, age-matched controls, number steps, distance walked, walking time were recorded a triaxial accelerometer, for seven consecutive days. A questionnaire regarding perceived London Chest Activity Daily Living (LCADL) scale used in order factors performance ADL. The severity was assessed two scales, whereas submaximal exercise capacity determined on basis 6MWT. Results: We evaluated 40 controls. comparison control values, mean significantly shorter (68.5 ± 25.8 min/day vs. 105.2 49.4 min/day; p < 0.001), as walked (3.9 1.9 km/day 6.4 3.2 km/day; 0.001). also fewer steps/day. most common self-reported lack infrastructure, social influences, willpower. 6MWT correlated results obtained accelerometer but not LCADL results. Conclusions: Patients are less active than healthy adults comparable age. Physical inactivity have immediate implications clinical practice, calling early intervention measures.
