About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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.

Treatment and study plan

field of regard-focused visual exploration therapy

Device

field of regard-focused visual exploration therapy in addition to conventional therapy

Other names: head mount display

Conventional Therapy

Other

conventional therapy for stroke rehabilitation

Primary outcomes

  1. Change in Field of regard-response time

    Time frame: Baseline, 4 weeks from baseline, 8 weeks from baseline

    time interval between target onset and response with field of regard setting

  2. Change in Field of regard-success rate

    Time frame: 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

  3. Change in Field of regard-head movement

    Time frame: Baseline, 4 weeks from baseline, 8 weeks from baseline

    sum of all quantified head-rotations with field of regard setting

Secondary outcomes

  1. Field of view-response time

    Time frame: Baseline, 4 weeks from baseline, 8 weeks from baseline

    time interval between target onset and response with field of view setting

  2. Field of view-success rate

    Time frame: 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

  3. Line bisection test

    Time frame: 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

  4. Star cancellation test

    Time frame: 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.

  5. Catherine Bergego Scale

    Time frame: 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
