Tolerance Study of Robotic-Assisted Virtual Reality Walking Rehabilitation for Non-Walking Stroke Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

GaitTrainer and Virtual Reality: Realization of Gait Trainer-assisted robot walking rehabilitation sessions without and with the addition of an immersive VR device. The proposed virtual stage will be a natural space (i.e. forest) of 360°. The subject will be able to explore the environment without moving. The created scene represents a straight path crossing a landscape composed of different natural elements. A fluid movement is obtained with the help of two sensors (trackers) of the HTC Vive device, placed at the level of the subject's feet. Moreover, thanks to these sensors the individual has a virtual representation of his lower limbs. Post-stroke patients will perform 3 conventional sessions (Gait Trainer alone) and 3 sessions with the immersive VR device (Gait Trainer + VR).

Study 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.

Eligibility

Primary outcome measure(s)

• CyberKinetosis — 2 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).
