NCT06722092

Brief Summary

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. 1.Can script training promote verbal functional communication of Cantonese-speaking PWA?
  2. 2.Can script training enhance nonverbal cognitive functions of Cantonese-speaking PWA?
  3. 3.Can VR magnify verbal and nonverbal treatment outcomes of script training of PWA?

Outcome Measures

Primary Outcomes (3)

  • Percentage accuracy of treatment probe correctly produced

    Participant's production accuracy of the trained scripts in read-aloud and no-cue conditions.

    From baseline up to 8-week post training

  • Time to produce each of the scripts in the treatment probe

    Participant's production time of the trained scripts in read-aloud and no-cue conditions.

    From baseline up to 8-week post training

  • Number of sessions to reach performance criteria in session probe

    From baseline up to 8-week post training

Secondary Outcomes (7)

  • Cantonese version of the Western Aphasia Battery (CAB) to measure aphasia severity

    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

    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

    From baseline up to 8-week post training

  • Subtest 1 (map search) and 3 (elevator counting) of Test of Everyday Attention to assess attention

    From baseline up to 8-week post training

  • Digit span forward and backward task to assess verbal short-term and working memory

    From baseline up to 8-week post training

  • +2 more secondary outcomes

Study Arms (3)

VR-based script training

EXPERIMENTAL
Behavioral: VR-based script training

Control

NO INTERVENTION

Computerized script training without VR

ACTIVE COMPARATOR
Behavioral: Conventional script training

Interventions

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.

VR-based 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.

Eligibility Criteria

Age30 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • a stroke onset more than six months, with an Aphasia Quotient (AQ) below 96.4, as evaluated by the Cantonese version of Western Aphasia Battery (CAB; Yiu, 1992),
  • 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

You may not qualify if:

  • 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.
