About this study

Official title: Effects of Virtual Prism Adaptation Therapy in Stroke Patients With Hemispatial Neglect

The purpose of this study is to investigate the effect of virtual prism adaptation therapy on hemispatial neglect in chronic stroke patients. This study is the randomized, double-blind, sham-controlled, cross-over design. Total 10 patients will be allocated randomly to either real virtual prism adaptation therapy or sham therapy with the wash-out period of more than 2 weeks. Two sessions (20min/session) per day, for 5days (total 10 sessions) will be provided. Behavioral outcomes will be measured before and after completing a total of 10 sessions therapy.

Being tested
Virtual Prism Adaptation Therapy, Sham Therapy
Medical subject headings
Stroke, Perceptual Disorders

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Virtual Prism Adaptation TherapyDevice

    Hand trajectory will deviate to the right side in the virtual reality.

  • Sham TherapyDevice

    The therapy is the same as the real virtual prism adaptation therapy, but there will be no deviation of the hand trajectory in the virtual reality.

Study groups in NCT03771872
Study groupRoleWhat they receive
Virtual Prism Adaptation TherapyExperimentalThis group will be provided with real virtual prism adaptation therapy. In the real therapy session, the hand trajectory will deviate to the right side in the virtual reality. The deviation angle will be adjusted according to the subject's adaptation. 20min-session will be provided twice a day for 5 days, then the total 10 sessions of therapy will be provided.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Behavioral Inattention Test (BIT) Score

    Range: 0(best) to 227(worst)

    Measured: Change from Baseline at 5 days

Secondary outcomes (4)
  1. BIT Conventional subtest score (BITC)

    Range: 0(best) to 146(worst)

    Measured: Change from Baseline at 5 days

  2. BIT Behavioral subtest score (BITB)

    Range: 0(best) to 81(worst)

    Measured: Change from Baseline at 5 days

  3. Comb and Razor Test

    Range: 0% deviation (best) to 100% deviation (worst)

    Measured: Change from Baseline at 5 days

  4. Catherine Bergego Scale (CBS)

    Range: 0 (best) to 30 (worst)

    Measured: Change from baseline at 5 days

Questions about this trial

What is this clinical trial studying?

A study testing Virtual Prism Adaptation Therapy in people with Stroke and Recovery of Function, run by Seoul National University Hospital at 2 sites in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 18 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Recruitment of subjects has been difficult.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Behavioral Inattention Test (BIT) Score (time frame: Change from Baseline at 5 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Mar 2020.
