Spatial Neglect

Keywords

spatial neglect, virtual reality, assessment

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.

Interventions

BEHAVIORALSpatial cognition assessment

The intervention will be composed of tasks assessing spatial cognition in a real environment (cancellation task, line bisection and baking tray task) and in a virtual environment (cancellation task, line bisection, baking tray task and localization tasks).The Catherine Bergego Scale (questionnaire) will also be used.

Design outcomes

Primary

Measure	Time frame	Description
Omissions in cancellation 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)
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

Secondary

Measure	Time frame	Description
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
Duration of eye fixation in each side of space during VR tasks	Baseline	Collected thanks to the VR headset
