Head Mount Display-based Virtual Reality Rehabilitation of Hemispatial Neglect

Virtual Reality Based Visual Perception Evaluation and Rehabilitation-pilot Study

Head-mounted display based virtual reality rehabilitation for hemispatial neglect.

The investigators examine about the efficacy of field-of-regard-focused visual exploration therapy implemented using a head-mounted display virtual reality system for hemispatial neglect rehabilitation following stroke.

Inclusion Criteria:

• presence of left hemispatial neglect as demonstrated by a score above the cut-off on the line bisection test or star cancellation test of the Behavioral Inattention Test, or mild-to-moderate neglect-related functional impairment defined by a score of 1-20 points on the Catherine Bergego Scale
• age 19 to 65 years
• first-time right hemispheric ischemic or haemorrhagic stroke as evidenced by brain imaging and medical records
• a score >25 on the Mini-Mental State Examination

Exclusion Criteria:

• presence of oculomotor palsies or visual defects as assessed via standard neurological examination
• orthopaedic disorders affecting neck movement
• inability to maintain a seated position.
