Brief Summary

This is an interventional, prospective, randomized, monocentric study designed to develop medical knowledge. Virtual reality is increasingly used in rehabilitation. The aim of virtual reality is to investigate motor interactions in a fictitious, configurable environment, in order to train specific functions and transpose improvements into everyday life. The main objective of this study is to investigate the influence of different moving virtual scenes on the general spatiotemporal parameters of pressure centers, in a sub-acute stroke rehabilitation context. This would help health professionals to assess the most suitable VR exercise in function of patient's difficulties. During this study, patient movements while viewing 8 different virtual reality scenes will be recorded using a motion platform during a single session.

Conditions

Stroke Rehabilitation; Postural Equilibrium

Outcome Measures

Primary Outcomes (2)

• Total length of pressure center displacement (in mm)

  Length of pressure will be recorded on a force platform under different conditions: * Eyes open with VR headset simulating a static environment * Eyes closed with VR helmet off * In 8 VR conditions simulating movement (in random order)

  During the procedure (virtual reality session).

• Displacement speed of the center of pressure (in mm.s-1)

  Displacement speed of the center of pressure will be recorded on a force platform under different conditions: * Eyes open with VR headset simulating a static environment * Eyes closed with VR helmet off * In 8 VR conditions simulating movement (in random order)

  During the procedure (virtual reality session).

Random order of virtual scenes

OTHER

Eight measurements on a stabilometry platform will be performed for each of the VR signals, in random order: Signal A Direction: anteroposterior Speed: 5 m/s Signal B Direction: anterior-posterior Speed: 5 m/s Signal C Direction: Oblique forward and downward Speed: 5 m/s Signal D Direction: Oblique forwards and upwards Speed: 5 m/s Signal E Direction: Oblique forwards and to the right Speed: 5 m/s Signal F Direction: Oblique forward and left Speed: 5 m/s Signal G Direction: antero-posterior + Clockwise tunnel rotation at 10°/s Speed: 5 m/s Signal H Direction: antero-posterior + Counter-clockwise tunnel rotation at 10°/s Speed: 5 m/s

Other: Assessing postural responses induced by visual stimulation (Visual Evoked postural responses, VEPR)

Interventions

Assessing postural responses induced by visual stimulation (Visual Evoked postural responses, VEPR) OTHER

The intervention will last 60 minutes and will include an assessment of the Berg Balance Scale (BBS), the collection of stabilometric data, the collection of the numerical difficulty scale, the Fast Motion Sickness Scale (FMS) and will end with a break after exposure to VR. The various conditions will be carried out in this order: * Eyes open with VR headset simulating a static environment * Eyes closed with VR helmet off * Eight measurements on a stabilometry platform will be taken for each of the VR signals, in random order
