Figure 3

Box plots of the accelerometer-derived parameters which differentiate between groups for the pairwise comparisons. (a) represents the time invested for the impulse phase, left side, and the X-orientation range during the impulse phase, right side. (b) represents the Z-acceleration minimum values during the stand-up and sit-down and. (c) represents the Z-acceleration AUC for the negative and positive impulse when standing-up and sitting-down. Finally, (d) represents the maximum and minimum Z-velocity peaks during the stand-up and sit-down.
