Obstacle test that could not be finalized because of difficulty was assigned the value 0. Following are the number of patients out of a total of 45 who completed the test: at T1: no stimulation—n = 37; peroneal stimulation/peroneal and thigh stimulation—n = 43; T2: no stimulation—n = 41; peroneal stimulation/peroneal and thigh stimulation—n = 45.
