Virtual Reliability System for Visual Spatial Attention Evaluation in Stroke Patients

February 22, 2026 updated by: National Taiwan University Hospital

Application of a Virtual Reliability System in the Evaluation of the Visual Spatial Attention in Stroke Patients

The researchers designed a software based on a head-mounted displays for virtual reality (HMD-VR) to evaluate the reaction time to stimuli presented at right or left visual field. The study will recruit 100 stroke patients with hemisphere lesions (50 patients for right and left each) and 100 age-matched healthy controls. The participants will conduct a simple reaction time task in VR, with stimuli designated in the left or right hemi-field. The stroke patients will also received traditional tests for hemi-neglect. Test-retest reliability of the assessment will be conducted in a subset of the control group. The stroke patients will be followed in 3-4 weeks.

Detailed Description

The researchers designed a software based on a head-mounted displays for virtual reality (HMD-VR) to evaluate the reaction time to stimuli presented at right or left visual field. The study will recruit 100 stroke patients with hemisphere lesions (50 patients for right and left hemisphere each) and 100 age-matched healthy controls. The participants will conduct a simple reaction time task in VR, with stimuli designated in the left or right hemi-field. The stroke patients will also receive traditional tests for hemi-neglect. The researchers will also collect the demographic data, cognition function and daily activity function. Test-retest reliability of the assessment will be conducted in a subset of the control group. The stroke patients will be followed in 3-4 weeks. The researchers will compare the results of a traditional hemi-neglect tests and VR-based tests and their changes in two occasions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

outpatient and inpatient rehabilitation unit in a medical center

Description

Inclusion Criteria for stroke patients:

  1. aged at least 20 years old
  2. diagnosed with stroke involving unilateral MCA and ACA territory
  3. with unilateral upper limb with normal function
  4. neurologically and medically stable.

Inclusion criteria for control group:

1) healthy adults, age-matched to stroke patients

Exclusion Criteria for both groups:

  1. with history of neurological or psychiatric conditions other than stroke;
  2. significant cognitive or speech problems that cause difficulties to cooperate with testing;
  3. significant visual problems (such as color blindness, visual loss, cataract, glaucoma or other major eye condition)
  4. upper limb musculoskeletal disorders to cause difficulties to use the keyboard or controller;
  5. history of seizure, vestibular dysfunction or vertigo
  6. can't tolerate HMD-VR

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
reaction time
Time Frame: 4 weeks
reaction time to the stimuli presented in the right or left hemi-field with VR software
4 weeks
hemineglect tests
Time Frame: 4 weeks
Paper-based behavior inattention test (BIT)
4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
ADL
Time Frame: 4 weeks

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2025

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
