“…The following gait parameters were assessed in the selected RCTs, in descending order of frequency: speed (cm/s) [ 7 , 15 , 17 , 18 , 19 , 22 , 23 , 38 , 40 , 41 ], step length (m) [ 15 , 17 , 18 , 19 , 22 , 23 , 38 , 41 , 42 ], and cadence (steps/min) [ 5 , 15 , 18 , 23 ]. These parameters were chosen because the unit of gait is the step and time-space parameters are essential for its assessment [ 2 , 52 , 53 , 54 , 55 ]. The measurement devices were in some cases also those providing the feedback [ 7 , 10 , 14 , 19 , 26 , 39 , 40 , 41 , 42 ].…”
