Brief Summary

The primary objective of this study is to evaluate the tolerance of the use of immersive virtual reality (VR) during robotic walking rehabilitation sessions by Gait Trainer (GT) in post-stroke patients.

Secondary objectives aim to evaluate the motivation to participate in VR sessions compared to conventional sessions, the participants' sense of presence within the virtual environment, and the usability of the rehabilitation device created. Finally, we will report the actual walking time and number of steps stroke patients take in VR sessions and conventional sessions.

Detailed Description

Robotic Assisted Gait Therapy using the GT has been shown to be effective in restoring gait to non-walking stroke patients. However, GaitTrainer rehabilitation sessions can result in fatigue, sling attachment discomfort, which can limit the duration, intensity and participation of patients. Immersive Virtual Reality (VR) via visio helmet is an innovative and playful approach that allows rehabilitation to focus on specific tasks, such as walking in controlled and environmentally friendly environments. Coupled with robotic assistance, it could promote patient adherence and active participation thanks to the presence of bio-feedback and its playful aspect. However, the GT has never been associated with a walking activity simulated by a VR system. VR can lead to adverse effects (i.e., cyberkinetosis) such as dizziness, nausea or headaches. Thus, it seems necessary to observe the tolerance of the virtual environment immersion during GT assisted walking rehabilitation sessions in stroke patients.

This protocol involves the recruitment of non-walking stroke participants who are being rehabilitated in a Physical Medicine and Rehabilitation (PMR) department and receiving Gait Trainer-assisted rehabilitation. The intervention will consist of Gait Trainer-assisted robotic walking rehabilitation sessions with and without the addition of an immersive VR device. Post-stroke patients will complete 3 conventional sessions (Gait Trainer alone) and 3 sessions with the VR device.

Primary Outcome Measures
NameTimeMethod
CyberKinetosis2 weeks

cyberkinetosis assessed by the Simulator Sickness Questionary (SSQ). This is a 16-item questionary evaluating different symptoms on a scale from 0 (not at all) to 4 (severely).

Secondary Outcome Measures
NameTimeMethod
Assessment of number of steps2 weeks

We will report the number of steps during the sessions with and without the VR device.

Evaluation of the sense of presence within the Virtual environmet2 weeks

the feeling of presence in the virtual environment will be assessed by the Presence Questionnaire (PQ). It consists of 19 items designed to assess the feeling of spatial presence. Each question uses a Likert-type scale ranging from 1 to 7.

Motivation to participate in immersive VR sessions2 weeks

Motivation to participate in walking rehabilitation sessions will be assessed using the Intrinsic Motivation Inventory (IMI). This is a multidimensional questionnaire used to estimate motivation to perform specific activities. The various items are evaluated on a Likert-type scale ranging from 1 to 7. The 4 subscales we'll be using are interest/pleasure, effort, usefulness and pressure/tension.

usability of the immersive VR rehabilitation device2 weeks

The usability of the rehabilitation device will be assessed using the System Usability Scale (SUS). This is a 10-item scale giving a final score out of 100. The higher the score, the greater the perceived usability of the system.

Assessment of walking time2 weeks

We will report the effective walking time (in minutes) during the sessions with and without the VR device.
