Figure 5From: Accelerometer-based wireless body area network to estimate intensity of therapy in post-acute rehabilitationBland-Altman plots of measure and estimate of active time for observed sessions. M3 and M1 are compared to time and motion (TM) analysis. On the Y-axis, differences between methods are expressed as: [(M-TM)/((TM+M)/2)*100]. On the X-axis, averaged active time is calculated as: [(M+TM)/2].Back to article page
