Correlations between the PW, video recording, and the SAB during a self-selected 5-minute slow walk. Correlation between the PW and video recording concerning the number of steps, walking distance, and intensity of walking (r=.79, P<.0001; r=.63, P<.001; r=.61, P<.001, respectively) and between the PW and SAB concerning energy expenditure estimation (r=.65, P=.0001).
