No relationship was seen between the other questionnaires and the SWA. Spearman rank correlation, intraclass correlation coefficients (ICC) and receiver-operating characteristics (ROC) curves were used to assess the relationship between the questionnaires and SWA.Īssessed by PAR, time spent at ≥3.0 metabolic equivalents (METs) correlated significantly (r=0.54, p<0.001) with equivalent measures from SWA, with an ICC of 0.40. Patients completed the PAR, Baecke, Physical Activity Scale for the Elderly (PASE) and Zutphen questionnaires. The aim of our study was to evaluate the Stanford Seven-Day Physical Activity Recall questionnaire (PAR) against the SenseWear armband (SWA) and compare its validity with three other physical activity questionnaires.Ĥ3 COPD patients wore the SWA for 7 days. Objective measures using activity monitors may take several days to obtain reliable results.

Quantification of daily physical activity is of clinical interest in chronic obstructive pulmonary disease (COPD).
