Brief summary
Head-mounted display based virtual reality rehabilitation for hemispatial neglect.
Detailed description
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.

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.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Field of regard-response time | Baseline, 4 weeks from baseline, 8 weeks from baseline | time interval between target onset and response with field of regard setting |
| Change in Field of regard-success rate | Baseline, 4 weeks from baseline, 8 weeks from baseline | percentage of correct responses (clicking the left or right mouse button in response to a blue or red target, respectively) with field of regard setting |
| Change in Field of regard-head movement | Baseline, 4 weeks from baseline, 8 weeks from baseline | sum of all quantified head-rotations with field of regard setting |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Star cancellation test | Baseline, 4 weeks from baseline, 8 weeks from baseline | The experimenter crossed out the two small, central stars of the sheet as an example, following which participants were asked to mark the remaining small stars. |
| Field of view-response time | Baseline, 4 weeks from baseline, 8 weeks from baseline | time interval between target onset and response with field of view setting |
| Catherine Bergego Scale | Baseline, 4 weeks from baseline, 8 weeks from baseline | a standardised checklist designed to detect the degree of neglect during everyday life via direct observation of functioning during ten tasks |
| Field of view-success rate | Baseline, 4 weeks from baseline, 8 weeks from baseline | percentage of correct responses (clicking the left or right mouse button in response to a blue or red target, respectively) with field of view setting |
| Line bisection test | Baseline, 4 weeks from baseline, 8 weeks from baseline | Participants were asked to bisect the given lines by marking the centre of each line using their preferred or unaffected hand |
