Fig. 3

Scatter and Bland–Altman plots of the four general (A) and six spatial (B) gait parameters of the OMCS and the Physilog®. In the lower row, the Y-axis of the plot corresponds to the difference of the two measurement systems (OMCS minus Physilog®), whereas the X-axis is the average of the two measurements. Solid lines mark the average difference for the whole sample, and the dashed lines correspond to the 95% limits of agreement. 3D path length measures the actual length of the trajectory of the foot during one cycle in 3D space
