Clinical Trial Summary

The purpose of this study is to compare and analyze how the visual gaze training in the afferent direction and the visual gaze training in the efferent direction using virtual reality affects the improvement of the neglect phenomenon in patients with subacute stroke with unilateral neglect.

Based on the behavioral intention test (BIT) test and the Mini-Mental Screening Examination test (MMSE) test for the group of unilateral neglected patients with stroke findings among all eligible patients for this experiment.

Appropriate subjects are selected and randomly divided into two groups. One group uses an afferent virtual reality program, and the other uses an efferent virtual reality program to train five times a week for a total of 4 weeks.

Before training, a computer experience scale 21 was additionally performed, and to find out the degree of unilateral negligence, evaluation was performed using the Behavioral Inattention Test (BIT) and Catherine Bergego Scale (CBS)22, and the angle of deflection (deviation angle), out-of-focus time, gaze time, failure rate, and head rotation trajectory were evaluated. In addition, reaction time, failure rate, and head rotation trajectory were evaluated using a virtual reality program (Assessment program-V2) to evaluate the degree of unilateral negligence. After that, BIT, CBS, and Assessment program-V2 tests are performed to determine the degree of improvement in visual ignorance due to each program.

• Neglect
• Perceptual Disorders
• Stroke

Intervention

Device:
• afferent virtual reality program
When visual gaze training is applied to the left unilateral neglected patient, the gaze direction can be divided into an afferent direction closer to the body and an efferent direction away from the body. The concentric direction moves the ball from the left to the center of the body.
• efferent virtual reality program
When visual gaze training is applied to the left unilateral neglected patient, the gaze direction can be divided into an afferent direction closer to the body and an efferent direction away from the body. The efferent direction moves from the center to the right.
