INTRODUÇÃO: Pacientes com doença pulmonar obstrutiva crônica (DPOC) tem atividade física reduzida. Barreiras que limitam a atividade física e a medida objetiva da limitação ainda são pouco estudadas nesta população. Conhece-las permite um planejamento adequado para incremento da atividade de vida diária (AVD). OBJETIVO: Comparar a AVD de portadores de DPOC e controles com um sensor de movimento, identificar barreiras que impedem a AVD e correlaciona-los à gravidade da dispneia, ao teste de caminhada de 6 minutos (TC6) e um escore de limitação da AVD. MÉTODOS: O número de passos, a distância percorrida em quilômetros e o tempo de caminhada foram registrados por um acelerômetro de bolso e um pedômetro durante 7 dias consecutivos. Um questionário de barreiras percebidas e a escala AVD (LCADL) foram utilizados para qualificar fatores que impedem a AVD. A dispneia foi medida por duas escalas distintas e a capacidade física submáxima pelo TC6. RESULTADOS: Foram avaliados 40 sujeitos com DPOC e 40 controles saudáveis. Os pacientes com DPOC realizaram tempo menor de caminhada (68,5 ± 25,8 minutos/dia vs. 105,2 ± 49,4; p < 0,001), menor distância (3,9 ± 1,9 km/dia vs. 6,4 ± 3,2; p < 0,001) e menor número de passos/dia. A falta de estrutura, influência social e falta de vontade foram as principais barreiras referidas para realização de AVD. O TC6 correlacionou-se com os resultados do acelerômetro, mas o LCADL não. CONCLUSÃO: Portadores de DPOC são menos ativos quando comparados a adultos saudáveis. Sedentarismo e as barreiras para atividade física tem implicação imediata na prática clínica indicando medidas de intervenção precoce

Abstract in English
INTRODUCTION: Patients with chronic obstructive pulmonary disease (COPD) have reduced physical activity. Barriers that limit physical activity and objective measures of limitation are poorly studied in this population. The knowledge of them allows a proper planning for increased physical activity. OBJECTIVES: To compare ADLs in COPD patients and controls using a motion sensor, identify perceived barriers that prevent AVD and correlate them to the severity of dyspnea, to the 6-minute walk test (6MWT) and a score of AVD limitation. METHODS: An pocket accelerometer and a pedometer recorded the number of steps, distance in Km and walking time for seven consecutive days. A survey of perceived barriers and the ADL scale (LCADL) were used to describe factors that prevent AVD. Dyspnea was measured by two different scales and submaximal exercise capacity by 6MWT. RESULTS: 40 subjects with COPD and 40 healthy controls were evaluated. Patients with COPD performed less time walking (68.5 ± 25.8 minutes / day vs. 105.2 ± 49.4; p < 0.001), shorter distance (3.9 ± 1.9 km / day vs. 6.4 ± 3.2; p < 0.001) and a smaller number of steps/day. The lack of infrastructure, social influences and unwillingness were the main barriers to performing ADLs. The 6MWT correlated with the results of the accelerometer, but not LCADL. CONCLUSION: Patients with COPD are less active compared to healthy adults. Sedentary and barriers to physical activity has immediate implications in clinical practice indicating early intervention measures
