SenseWear Armband and Stroke: Validity of Energy Expenditure and Step Count Measurement during Walking

Figure 4

Scatterplot between gait speed and percent difference of step count as measured by the Step Activity Monitor (SAM) and the SenseWear Armband (SWA). Percent differences less than zero indicate overestimation by the SWA. Each participant has four data points (one for each arm for each 6-minute walk test), viewed in a vertical line from the gait speed value. Note: there are only two data points for the participant for whom the SWA malfunctioned on the hemiplegic arm.
