All participants practiced one session a day of AlterG (for 40min), six days a week, for four weeks (for a total amount of 24 sessions). All patients were trained using BWS, and treadmill speed (S) to allow the participant to walk with the intermittent support of one physiotherapist to help with balance and coordination. A qualitative (using FAC) and quantitative (spatio-temporal parameters and dynamic electromyography) gait assessment before and after the end of the gait training was performed.

All participants practiced one session a day TGT (for 40min), six days a week, for four weeks (for a total amount of 24 sessions). All patients were trained using FAC-tailored physiotherapist assistance, to allow the participant to walk with the intermittent support of one physiotherapist to help with balance and coordination (FAC 2), with the visual supervision of one physiotherapist (FAC 3), or independently without using the handrails (FAC 4). Physiotherapist assistance, and S were checked and adapted to subjects' progresses across the AlterG sessions.

BWS and S were reduced progressively and increased, respectively, across the AlterG sessions in keeping with patients progresses.

FAC is a functional walking test that evaluates ambulation ability. This 6-point scale assesses ambulation status by determining how much human support the patient requires when walking, regardless of whether or not they use a personal assistive device

GCD is the time interval between two successive occurrences of one of the repetitive events of walking, herein the right heel strike),
