Figure 3.

The left side of the figure shows the correlation plots between laboratory and IMU measures of 5 sit-to-stand total time (totT), mean concentric time (McT), mean concentric velocity (McV), mean concentric force (McF) and mean power (MP). Equation, Pearson’s correlation coefficient (r), p-value, SEE and sample size are reported along with regression (dashed) and identity (solid) lines. The right side of the figure shows the Bland Altman analysis comparing laboratory and IMU of the same variables. Individual differences between lab and IMU measures are plotted as a function of the mean of the two. Bias, R², and Z-score are reported along with the LOA (dashed lines) and bias (solid lines).
