  1. Results are shown for Cadence and Stride Length as median (IQR); for the Borg scale as the reported value; for Heart Rate (HR) as the steady-state value (mean of the last 3-min of the 6mWT); and for the percentage of Maximal Heart Rate (%HRmax) as the computed value as in (60).Cadence and stride length could not be computed for ID6 due to the crutches. The last three rows present the median (min, max) of each group (Symmetry and Speed) and of All participants
