Stroke Clinical Trial
Official title:
Effectiveness of Audiovisual Stimulation in Immersive Virtual Reality to Improve Visual Perception and Driving Performance: a Pilot Study
The goal of this clinical trial is to evaluate the effectiveness of an immersive virtual-reality (IVR) based stimulation program, in improving visual perception for people who have lost their driver's license due to perceptual or cognitive impairments. The main questions it aims to answer are: 1. Can the 6-week IVR stimulation program help improve driving performance? 2. Will participants experience improvement in visual detection and perception after training? Study Design Summary: - Participants will be randomized into a waitlist group or intervention-first group - The VR-based intervention will consist of training every 2 days for six weeks - Waitlist group will wait 6 weeks before starting intervention at study midpoint (week 7) - Intervention-first group will begin with intervention (week 1-6) and then stop intervention at study midpoint - Participants will complete tests related to driving performance, visual attention, and visual fields at the start of study, midpoint, and end of study Researchers will analyze data for changes from baseline in outcome measures.
This clinical trial will be an interventional, cross-over, single blind, randomized, supportive care, single-center study lasting 12 weeks with a target recruitment of 30 participants. SCREENING AND BASELINE TESTS Potential participants will be identified from patients receiving routine care at Toronto Western Hospital by their ophthalmologist. After obtaining informed consent and screened for inclusion, the research coordinator will set up appointments for each participant to complete baseline tests related to driving performance, visual attention, and visual fields. Participants will also practice the IVR program and be assessed for IVR sensitivity, or cybersickness, using the Virtual-Reality Induced Symptoms and Effects (VRISE) questionnaire. Participants will be randomized into a Waitlist group or Intervention-First group. The Intervention-First group will be given a head-mounted display (HMD) to take home for training. INTERVENTION (Week 1 - 12) Period 1 (Week 1-6): - Waitlist Group has no intervention - Intervention-First group trains at home every 2 days using HMD All participants are booked for their second appointments to repeat baseline tests once Period 1 is complete. Intervention-first group will return their HMD to the researchers and Waitlist group will be given their HMD to take home. Period 2 (Week 7-12) - Waitlist Group trains at home every 2 days using HMD - Intervention-First group has no intervention All participants are booked for their third appointments to repeat baseline tests once Period 2 is complete. Waitlist group will return their HMD to researchers. POST-INTERVENTION Analysis of outcome measures: 1. Period 1 (Waitlist Group vs Intervention-First Group) 2. Waitlist Group (Period 1 vs Period 2) 3. Intervention-First Group (Period 1 vs Period 2) ;
