Example for the calculation of the distance between the ankles and pelvis. As an example, one step of BASE and one step of WS80 are shown. The line indicates the pelvis position and the markers indicate the position of the (paretic and non-paretic) ankle at that point of the gait cycle. A distance of 0 means exactly in the center of the treadmill, the positive axis shows deviations from the center of the treadmill towards the side of the paretic leg. For each step, the distance between the pelvis and both ankles was calculated at the time instance of maximal and minimal lateral pelvis displacement as shown
