Virtual reality effects on dynamic stability of gait in stroke survivors: a study protocol of a randomised controlled trial to assess the role of user experience

Introduction In recent years, virtual reality (VR) training has gained momentum in stroke rehabilitation for reducing falls by enhancing balance and stability. Objectives VR interventions offer superior immersion, interactivity and creative engagement compared with conventional therapies.

However, the precise mechanisms by which VR influences dynamic stability remain unclear. Moreover, there is currently limited information regarding user experience (UX) in this context.

Methods and analysis This study protocol outlines a randomised controlled trial designed to evaluate the effects of an immersive VR intervention on the dynamic stability of gait parameters in stroke survivors, incorporating an assessment of UX. Two groups of subjects will be enrolled in this study, including patients with a stroke within the previous 6 - 12 months who will receive (1) 3 weeks of immersive VR training (intervention) or (2) conventional rehabilitation (control).

The primary outcome of the study will be dynamic stability measures and the UX. The secondary outcomes include anxiety and depression, fatigue, functional mobility, functional walking ability, static balance, fear of falling and adverse effects.
