VR and Script Training of PWA
- Conditions
- Aphasia, AcquiredChronic Stroke
- Interventions
- Behavioral: VR-based script trainingBehavioral: Conventional script training
- Registration Number
- NCT05667480
- Lead Sponsor
- The Hong Kong Polytechnic University
- Brief Summary
The goal of this intervention study is to investigate the effects of immersive virtual reality in rehabilitation of language and communication of individuals with post-stroke aphasia. The main research questions are:
1. Is VR-based script training a feasible treatment to Cantonese-speaking PWA?
2. Will VR-based script training, when compared to conventional script training, better enhance treatment outcomes in functional communication of PWA?
Participants will be assessed before, in the middle of, immediately after treatment and 8-week post treatment in terms of their performance on:
1. Accuracy and time for producing trained scripts.
2. Accuracy and time for producing un-trained scripts
3. Standardized aphasia test on severity of language impairment
4. Standardized aphasia test on functional communication
The participants will be randomly allocated to receive one of the treatment:
1. Virtual reality-based computerized script training; or
2. Computerized script training without virtual reality Researchers will compare the treatment outcomes of the two treatment conditions and see if treatment with virtual reality would better promote outcomes when compared to training without virtual reality.

- Primary Outcome Measures
Name Time Method Percentage correct in reading aloud the sentences included in the trained scripts From baseline up to 1-week post training Trained scripts will be shown in written form while the PWA will be asked to read aloud the scripts.
Time required in read aloud of trained scripts From baseline up to 1-week post training Total time to read aloud the trained scripts
Percentage correct in spontaneous production of the sentences included in the trained scripts From baseline up to 1-week post training No written cue will be provided while the PWA will produce the scripts upon questions.
Time required for spantaneous production of trained scripts From baseline up to 1-week post training No written cue will be provided while the PWA will produce the scripts upon questions.
- Secondary Outcome Measures
Name Time Method CAB From baseline up to 1-week post training Cantonese version of the Western Aphasia Battery
Percentage correct in producing untrained but related scripts From baseline up to 1-week post training No written cue will be provided while the PWA will produce the untrained scripts that share similar contexts with the trained scripts.
CANELT From baseline up to 1-week post training Cantonese version of the Amsterdam-Nijmegen Everyday Language Test (ANELT; Blomert et al., 1994)
