Internal consistency between ||A||_95 computed on the wrist sensors (A/) and on the foot sensors (B/) between acquisition 1 (without playset) and acquisition 2 (with playset) and for the wrist sensor between acquisition 2 and acquisition 3 (with playset and with elbow sensors) (C/). Internal consistency between ||A||_CPM computed on the wrist sensors (D/) and on the foot sensors (E/) between acquisition 1 (without playset) and acquisition 2 (with playset) and for the wrist sensor between acquisition 2 and acquisition 3 (with playset and with elbow sensors) (F/). ICC are given for each plot. All 104 IMU-measurements were included in this analysis. ICC: interclass correlation coefficient. ||A||_95: Norm acceleration 95th centile; ||A||_CPM: Mean counts per minute computed on the norm acceleration
