Virtual Reliability System for Visual Spatial Attention Evaluation in Stroke Patients

• Conditions: Neglect, Hemispatial; Stroke Sequelae

• Registration Number: NCT05332964
• Lead Sponsor: National Taiwan University Hospital

Brief Summary

The researchers designed a software based on a head-mounted displays for virtual reality (HMD-VR) to evaluate the reaction time to stimuli presented at right or left visual field. The study will recruit 100 stroke patients with hemisphere lesions (50 patients for right and left each) and 100 age-matched healthy controls. The participants will conduct a simple reaction time task in VR, with stimuli designated in the left or right hemi-field. The stroke patients will also received traditional tests for hemi-neglect. Test-retest reliability of the assessment will be conducted in a subset of the control group. The stroke patients will be followed in 3-4 weeks.

Detailed Description

The researchers designed a software based on a head-mounted displays for virtual reality (HMD-VR) to evaluate the reaction time to stimuli presented at right or left visual field. The study will recruit 100 stroke patients with hemisphere lesions (50 patients for right and left hemisphere each) and 100 age-matched healthy controls. The participants will conduct a simple reaction time task in VR, with stimuli designated in the left or right hemi-field. The stroke patients will also receive traditional tests for hemi-neglect. The researchers will also collect the demographic data, cognition function and daily activity function. Test-retest reliability of the assessment will be conducted in a subset of the control group. The stroke patients will be followed in 3-4 weeks. The researchers will compare the results of a traditional hemi-neglect tests and VR-based tests and their changes in two occasions.
