Virtual Reality in Aphasia Telerehabilitation
- Conditions
- Aphasia, Acquired
- Interventions
- Behavioral: VR-treatmentBehavioral: Treatment as usual
- Registration Number
- NCT04828759
- Lead Sponsor
- University of Oulu
- Brief Summary
The main purpose of this study is to evaluate the use of the immersive 3D HMD VR technology in the language intervention with a home-based telerehabilitation approach for people with aphasia. The assessments will be conducted at the baseline (prior the intervention periods) and after each intervention period (i.e. after the VR-intervention period and the waitlist period).
- Detailed Description
The purpose of the present project is to study the effects, feasibility, and the participants' experiences of this novel kind of language intervention. The effects of the intervention will be studied with various outcome measures in terms of language performance, functional communication, and quality of life. The aim is to explore the VR-intervention on the group level and with a randomized waitlist control group design (or delayed crossover design). In this study, the people with aphasia will be practicing at their home with support of their relatives, and participants will also receive regular remote guidance by a speech and language therapist (SLT) during the intervention. The relatives are also involved in the assessment process.

- Active epilepsy / migraine (< 3 years)
- Severe apraxia of speech
- Inability to act according to given instruction
- Severe neuropsychological disorder or the decline of cognitive / memory functions, which would significantly affect for training during the VR-intervention
- Vision or hearing impairment which would prevent the use of VR HMD
- if the participant's treatment or medication is unsuitable with the use of VR HMD device as assessed by the physician
- if the participant has the pacemaker or implantable (electric) medical device

Group Intervention Description VR-treatment, then Treatment as usual VR-treatment Participants will receive 8 weeks of VR-treatment. Participants are allowed to practice as much as they wish during the VR-intervention. However, they are given a recommendation of the amount of practice (5 h / week). Before the VR-intervention, the participants will receive a guidance for using the VR-devices (i.e. orientation period) by the SLT. Participants will be able to contact the SLT freely during the 8 weeks VR-intervention period. After the orientation period, the participants will be practicing at their homes independently. However, they will receive remote guidance by the SLT. The guidance includes weekly remote guidance sessions by SLT (8 x 45 min) to ensure that training is fluent and unproblematic. Additionally, the content of exercises can be modified during these sessions. The SLT is also able to monitor the training of participants with the system. Devices: VR headset and controller, Tablet computer. Treatment as usual, then VR-treatment Treatment as usual Wait list control group: During the waitlist period the participants will receive the traditional speech and language therapy rehabilitation offered by (if offered) the general health care system in their own home municipality. The amount of rehabilitation is not controlled during the wait list period. However, the amount of received traditional speech and language rehabilitation in waitlist period will be documented. The waitlist control group will receive the same VR intervention period after the 8 weeks waitlist period.
- Primary Outcome Measures
Name Time Method Change in language abilities from baseline to week 9 and to week 18 Change from baseline to week 9 and to week 18 Language abilities are assessed using language quotient LQ score of Western Aphasia Battery (WAB), performed at the baseline (prior the intervention periods) and after each intervention period (i.e. after the VR-intervention period and the waitlist period)
Change in quality of life from baseline to week 9 and to week 18 Change from baseline to week 8 and to week 18 Quality of life is assessed with Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39), performed at the baseline (prior the intervention periods) and after each intervention period (i.e. after the VR-intervention period and the waitlist period)
Change in naming abilities from baseline to week 9 and to week 18 Change from baseline to week 9 and to week 18 Naming abilities for nouns and verbs are assessed with Boston Naming Test (BNT) and TNT-test (action naming test in Finnish) performed at the baseline (prior the intervention periods) and after each intervention period (i.e. after the VR-intervention period and the waitlist period)
Change in verbal fluency from baseline to week 9 and to week 18 Change from baseline to week 9 and to week 18 Verbal fluency is assessed using multiple categories (produced words per one minute in each category), performed at the baseline (prior the intervention periods) and after each intervention period (i.e. after the VR-intervention period and the waitlist period)
Change in functional communication skills from baseline to week 9 and to week 18 Change from baseline to week 9 and to week 18 Functional communication skills are assessed with Communication Effectiveness Index (CETI), performed at the baseline (prior the intervention periods) and after each intervention period (i.e. after the VR-intervention period and the waitlist period)
- Secondary Outcome Measures
Name Time Method Participants' experiences of the waitlist period After waitlist period, at the week 9 or at the week 18, depending of the group the patient has been randomized The structural survey of participants' experiences of the waitlist period
Data collected by VR-devices regarding the performance of participants during the VR-intervention Through the VR-intervention up to 8 weeks or through the weeks 10-17, depending of the group the patient has been randomized Amounts of training (in minutes) and e.g. naming speed and range of head movements collected automatically by VR-devices
Participants' experiences of the VR-intervention After VR-intervention period, at the week 9 or at the week 18, depending of the group the patient has been randomized The structural survey of participants' experiences of the VR-intervention.
Attrition rates during the study. Through study completion, up to 18 weeks Amount of drop outs of participants during the study,
Date collected by remote sessions regarding the experiences of participants and feasibility of VR-intervention Weekly during the VR-intervention up to 8 weeks or through the weeks 10-17, depending of the group the patient has been randomized Data collected with semi-structural interview during remote guidance sessions (8 times during the VR-period) by the researcher. In addition, participants will be able to contact the researcher freely during the 8 weeks VR-intervention period.
