Official title
Can Immersive Virtual Reality Magnify Treatment Outcomes of Script Training on Cantonese Speakers with Chronic Aphasia: a Randomized Controlled Trial
Overview
The goal of this RCT is to investigate if computerized script training may promote functional communication and nonverbal cognitive functions of Cantonese-speaking PWA, and whether VR may further magnify the treatment outcomes. The main research questions are: 1. Can script training promote verbal functional communication of Cantonese-speaking PWA? 2. Can script training enhance nonverbal cognitive functions of Cantonese-speaking PWA? 3. Can VR magnify verbal and nonverbal treatment outcomes of script training of PWA?
Interventions
- Behavioral VR-based script training
The PWA will wear a head-mounted VR device (e.g., Metaverse Oculus Quest 2 or other commercially available devices) for 30 minutes, which intends to create an immersive environment for training. Scripts trained in the computerized script training program in a particular session will be practiced. Cinematic 360˚ photo-real scenarios of daily contexts such as a restaurant or a grocery store will be displayed in the device while a communication partner, e.g., a waiter in the restaurant or a shopkee - Behavioral Conventional script training
The flow of training is identical to the VR condition, except that photos depicting the scenarios and prerecorded conversational turns will be presented to the PWA on a computer screen with the same procedures mentioned in the VR condition.
Primary outcome measures
- Percentage accuracy of treatment probe correctly produced [Time frame: From baseline up to 8-week post training]
- Time to produce each of the scripts in the treatment probe [Time frame: From baseline up to 8-week post training]
- Number of sessions to reach performance criteria in session probe [Time frame: From baseline up to 8-week post training]
Secondary outcome measures (7)
- Cantonese version of the Western Aphasia Battery (CAB) to measure aphasia severity [Time frame: From baseline up to 8-week post training]
- Cantonese version of the Amsterdam-Nijmegen Everyday Language Test to measure verbal communication effectiveness in conversation via 20 culturally appropriate scenarios [Time frame: From baseline up to 8-week post training]
- Cantonese version of the 20-item Communication Outcome after Stroke (Can-COAST) as a self-reported outcome on communication and quality of life [Time frame: From baseline up to 8-week post training]
- Subtest 1 (map search) and 3 (elevator counting) of Test of Everyday Attention to assess attention [Time frame: From baseline up to 8-week post training]
- Digit span forward and backward task to assess verbal short-term and working memory [Time frame: From baseline up to 8-week post training]
- Test of Nonverbal Intelligence-third edition (TONI-3) to assess executive function [Time frame: From baseline up to 8-week post training]
- Wisconsin Card Sort Test (WCST) to assess executive function [Time frame: From baseline up to 8-week post training]
