Description détaillée
After obtaining consent and screening, eligible participants are randomized to the treatment or control groups.
First, all participants are issued a wearable tracker to gauge baseline activity for at least 5 days.
During the intervention phase, participants undergo 12 treatment sessions, 2x a week for 6 weeks.
Assessments are conducted at pre-intervention, post-intervention, and 1-month followup.

Comparateur actif: Thérapie VR à base de tapis roulant conventionnelle
Les participants au groupe témoin (VR-CTGT) s'engageront dans une formation à la marche en utilisant la technologie VR + C-Mill, qui implique une marche assistée par le tapis roulant sur un tapis roulant tout en interagissant avec des scénarios virtuels moins immersifs présentés sur les écrans.

|
Expérimental: VR-Assisted Overground Gait Therapy
Participants in the treatment group (VG-AOGT) will engage in gait training within a newly developed immersive virtual reality (VR) environment.
This setup features self-propelled overground walking influenced by three different virtual environments designed to mimic real-world conditions.
The immersive technology used is HTC VIVE Focus Vision, enabling participants to practice walking in real-world environments and gait tasks.

Activity Zone Minutes
Délai: Continuous tracking from Screening to Week 10
|
Fitbit calculates maximum heart rate (HR) from user age (Max HR = 220 - age) and defines Activity Zone thresholds based on percentages of max HR (Fat Burn 50-69%, Cardio/Peak >70%).
Activity Zone Minutes (AZMs) are an intensity-weighted measure of activity.
AZM (count) is based on sustained heart rate over time: 1 AZM per minute in the Fat Burn Zone (50-69% max HR) and 2 AZMs per minute in the Cardio/Peak Zones (>=70% max HR).

Pourcentage de position
Délai: Baseline, semaine 7, semaine 10
|
Avec la passerelle PKMAS Zeno (Protokinetics), les participants marchent sur un tapis de pression de 14 pieds pour capturer la cinématique de la marche.
Pendant le cycle de démarche, chaque pied alterne entre être en contact avec le sol (phase de position) et non en contact avec le sol (phase de balançoire).
Le pourcentage de position (pour cent) est la proportion du cycle de démarche pendant lequel un pied reste en phase de position.
