Effects of proximal training of a VR-based unilateral spatial neglect rehabilitation support system on activities of daily living under VR and real environments

JRCT ID: jRCT1031230244

Registered date:19/07/2023

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Stroke
• Date of first enrollment: 19/07/2023
• Target sample size: 1
• Study type: Interventional

Intervention(s)

Proximal training using a Virtual Reality (hereinafter referred to as VR) type semi-lateral space neglect rehabilitation support system will be conducted.
Proximal training will be conducted once a day, 30 minutes per session, 5 times a week for a total of 10 sessions over 2 weeks. If the patient is absent from rehabilitation due to illness or other reasons, the 10 sessions will be completed.
In the proximal training, the patient wears the Head Mounted Display and holds the dedicated controller on the upper limb of the non-paralyzed side. The patient is asked to perform a reaching motion by being given the task, "Please reach out and touch an object (visible in the VR space). When they are able to reach out as instructed, they receive feedback via electrical stimulation. In the slit system, release and move (release: gradual shutting out of information. Movement: moving attention to the neglected side). The slit system also uses a function linked to the evaluation results to provide intensive slit-based intervention to the neglected area. The success rate of the proximal training task at each session is evaluated.
