ABSTRACT

OBJECTIVE:

To evaluate the ability of COPD patients to perform activities of daily living (ADL); to identify barriers that prevent these individuals from performing ADL; and to correlate those barriers with dyspnea severity, six-minute walk test (6MWT), and an ADL limitation score.

METHODS:

In COPD patients and healthy, age-matched controls, the number of steps, the distance walked, and walking time were recorded with a triaxial accelerometer, for seven consecutive days. A questionnaire regarding perceived barriers and the London Chest Activity of Daily Living (LCADL) scale were used in order to identify the factors that prevent the performance of ADL. The severity of dyspnea was assessed with two scales, whereas submaximal exercise capacity was determined on the basis of the 6MWT.

RESULTS:

We evaluated 40 COPD patients and 40 controls. In comparison with the control values, the mean walk time was significantly shorter for COPD patients (68.5 ± 25.8 min/day vs. 105.2 ± 49.4 min/day; p < 0.001), as was the distance walked (3.9 ± 1.9 km/day vs. 6.4 ± 3.2 km/day; p < 0.001). The COPD patients also walked fewer steps/day. The most common self-reported barriers to performing ADL were lack of infrastructure, social influences, and lack of willpower. The 6MWT distance correlated with the results obtained with the accelerometer but not with the LCADL scale results.

CONCLUSIONS:

Patients with COPD are less active than are healthy adults of a comparable age. Physical inactivity and the barriers to performing ADL have immediate implications for clinical practice, calling for early intervention measures. .
RESUMO

OBJETIVO:

Avaliar a capacidade de portadores de DPOC em realizar atividades de vida diária (AVD), identificar barreiras que impedem a sua realização, e correlacionar essas barreiras com gravidade da dispneia, teste de caminhada de seis minutos (TC6) e um escore de limitação de AVD.

MÉTODOS:

Nos pacientes com DPOC e controles saudáveis pareados por idade, o número de passos, a distância percorrida e o tempo de caminhada foram registrados por um acelerômetro tridimensional durante sete dias consecutivos. Um questionário de barreiras percebidas e a escala London Chest Activity of Daily Living (LCADL) foram utilizados para identificar os fatores que impedem a realização de AVD. A dispneia foi medida por duas escalas distintas, e a capacidade física submáxima foi determinada com base no TC6.

RESULTADOS:

Foram avaliados 40 sujeitos com DPOC e 40 controles. Os pacientes com DPOC, comparados aos controles, realizaram menor tempo de caminhada (68,5 ± 25,8 min/dia vs. 105,2 ± 49,4 min/dia; p < 0,001), menor distância caminhada (3,9 ± 1,9 km/dia vs. 6,4 ± 3,2 km/dia; p < 0,001) e menor número de passos/dia. As principais barreiras referidas para realização de AVD foram falta de estrutura, influência social e falta de vontade. A distância caminhada no TC6 correlacionou-se com os resultados do acelerômetro, mas não os resultados da LCADL.

CONCLUSÕES:

Portadores de DPOC são menos ativos quando comparados a adultos saudáveis com idade comparável. O sedentarismo e as barreiras para a realização de AVD têm implicações imediatas na prática clínica, exigindo medidas precoces de intervenção. .
