• Lead Sponsor: Université Paris Cité

Brief Summary

Unilateral spatial neglect (USN) is a highly-prevalent neuropsychological syndrome following a cerebral stroke characterized by massive impairments in daily life. The evaluation and the rehabilitation of USN encounter many limits whereas immersive virtual reality (VR) could be an efficient tool to go through these limits by imitating an environment of perception and action very close to the real one. The investigators will test a multisensory battery of evaluation based on VR for the diagnostic of USN.

Arm && Interventions

Group	Intervention	Description
Spatial cognition assessment	Spatial cognition assessment	A single session of spatial cognition assessment (baseline) will be proposed to participants. This assessment will be based on paper-and-pencil tasks and immersive virtual reality tasks (with an HTC Vive Pro Head-Mounted-Display). The assessment will last around 1 hour.

Primary Outcome Measures

Name	Time	Method
Omissions in cancellation tasks	Baseline	Number and localization in space
Number of the cubes in each side of space in the Baking Tray Tasks	Baseline	16 cubes have to be disposed
Detections in the localization tasks	Baseline	Number and localization in space
Deviation in line bisection tasks	Baseline	Deviation of the bisection from the true center of the lines (in mm)

Secondary Outcome Measures

Name	Time	Method
Duration of eye fixation in each side of space during VR tasks	Baseline	Collected thanks to the VR headset
Completion time of each task	Baseline	(in s)
Score in the Catherine Bergego Scale (CBS)	Assessed within the same week as Baseline	Functional assessment scored by the occupational therapists. Minimum: 0 / Maximum: 30 / Higher scores mean a better outcome
