Experimental design showing the chronology of assessments. One week after arrival at the rehabilitation center (T1), participants were assigned to the MI or control group and started to perform MI or the control task concomitantly with physical therapy, up to one week preceding the end of the rehabilitation program (T4). Participants were tested at their arrival to the center (T1), after prosthesis fitting once they could walk with it safely (T2), at an equivalent time of rehabilitation (T3), at an equivalent functional rehabilitation level before leaving the center (T4), and six weeks after the end of the rehabilitation program (T5)
