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.

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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
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
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.
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
