Figure 5

SPM paired Hotelling’s T2 test on the three-dimensional BCoM trajectory while walking at 1.1 m/s versus 1.4 m/s. Approximate double support (DS) and single support (SS) periods are shown to ease the understanding of the plot (a). The same results are mapped, by referring to the illustrated color ramp on the right, on each point of the mean 3D BCoM trajectory at 1.1 m/s (b). The greater the SPM{T2}, the greater the differences between the two compared conditions. The black, solid arrow indicates the walking progression direction; 0%, 25%, 50% and 75% of gait cycle are indicated together with the local BCoM displacement direction (dashed grey arrows).
