VR and Scrip Training of PWA, Randomized Controlled Trial (VRSTPWA)
Can Immersive Virtual Reality Magnify Treatment Outcomes of Script Training on Cantonese Speakers with Chronic Aphasia: a Randomized Controlled Trial
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:
- Can script training promote verbal functional communication of Cantonese-speaking PWA?
- Can script training enhance nonverbal cognitive functions of Cantonese-speaking PWA?
- Can VR magnify verbal and nonverbal treatment outcomes of script training of PWA?

- premorbid fluent Cantonese speakers,
- aged between 30 and 80 years,
- no reported progressive neurogenic disorders such as dementia or Parkinson's disease,
- no motor speech disorders of moderate to severe level, and
- normal or corrected-to-normal vision and hearing functions
Exclusion Criteria:
- concurrent participation in other aphasia treatment trials, and
- incompatibility with immersive VR exposure such as complains of nausea, headache, or other severe discomforts during trial use of a head-mounted device during screening.

Experimental: 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 shopkeeper of a grocery store will initiate the conversation by producing the corresponding part of the script.
The PWA will be given time to respond.
Upon the completion of PWA's respond, the next conversational turn will be initiated.
The clinical assistant, who accompanies the PWA in the entire training session, will control the flow of the 360 ˚ videos.

|
Active Comparator: Computerized script training without VR
|
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.

|
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
|
The questionnaire consists of 20 questions, and participants will be asked to evaluate their functional communication and quality of life based on a 5-point Likert scale.
Higher scores reflect better functional communication performance and quality of life.
|
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
|
The sub-test 1 aims to tap sustained and selective visual attention via identifying the target symbol in a map while the sub-test 3 assesses auditory selective attention via counting the number of target tones in the presence of distractors with different tones.
|
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
|

Time Frame: From baseline up to 8-week post training
|
A norm-referenced test that uses abstract figures to evaluate abstract reasoning and problem-solving.
|
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
|
WCST assesses cognitive flexibility and reasoning via matching cards with respect to color, quantity, and shape upon different rules and feedback given.
|
From baseline up to 8-week post training
