- Conditions
- Stroke
- Interventions
- Device: Virtual mirror therapy via VR headset
- Registration Number
- NCT04592757
- Lead Sponsor
- Thomas More University of Applied Sciences
- Brief Summary
The purpose of this implementation study is - primarily - to investigate the feasibility, acceptability, tolerability of a new virtual reality application in stroke patients, and -secondarily - to gain initial insights in the preliminary clinical effects of this application.
- Detailed Description
Although immersive technologies have great potential in healthcare, they are still relatively unknown and underutilized in this field. In this study a new virtual reality (VR) application will be implemented and tested in two groups of stroke patients (10 acute phase/10 chronic phase). In an attempt to reactivate the affected upper limb in stroke patients, therapists often use mirror therapy. Using a mirror, the movement of a paralyzed limb is feigned in order to reprogram the brain. A patient performs exercises with the healthy limb, but through the mirror the patient seems to use the affected limb. A high number of repetitions is essential to stimulate the so-called neuroplasticity of the brain, but this makes mirror therapy monotonous. In addition, the therapy also has its limitations. Activities are limited by the physical boundaries of the modality, with exercises largely limited to distal movements and simple functional activities. Larger, free-standing mirrors provide a wider range of motion for therapeutic activities, but offer less protection against environmental distraction. With VR, these obstacles can be overcome. By focusing on virtual mirror therapy using a VR headset, therapists hope to create a more pleasant and realistic experience for the patients.

Group Intervention Description Subacute stroke patients Virtual mirror therapy via VR headset Training with new virtual mirror therapy application. During 12 sessions of approximately 30 minutes. Chronic stroke patients Virtual mirror therapy via VR headset Training with new virtual mirror therapy application. During 12 sessions of approximately 30 minutes.
- Primary Outcome Measures
Name Time Method Change from baseline in patient attitude towards the VR mirror therapy Before the start of the first session and immediately after finishing the last session. Assess change in patient attitude towards the VR mirror therapy with the Unified Theory of Acceptance and Use of Technology (UTAUT) questionnaire survey. The UTAUT questionnaire survey for end-users consists of 20 items with five response options ranging from "Totally disagree" (1) to "Totally agree" (5), and returns scores ranging from 20 to 100. The questionnaire survey consists of 7 subscales, for most of which higher scores indicate a more positive attitude towards the VR mirror therapy.
Usability of the VR mirror therapy: System Usability Scale (SUS) Immediately after finishing the last session. Assessment of ease of use of the VR mirror therapy with the System Usability Scale (SUS). The SUS is a 10-item questionnaire with five response options for respondents; from "strongly disagree" to "strongly agree", and returns scores ranging from 0 to 100. A higher SUS score indicates better usability.
Patient satisfaction: Client Satisfaction Questionnaire (CSQ-8) Immediately after finishing the last session. Assessment of client satisfaction with the VR application with the Client Satisfaction Questionnaire (CSQ-8). The CSQ-8 consists of 8 items with four response options and returns scores ranging from 8 to 32. Higher scores indicate higher satisfaction.
Therapy adherence Immediately after finishing each session. Measure therapy adherence by registering the number of fully completed 30 min sessions.
Change from baseline in tolerability (Do participants experience symptoms of simulator sickness?) Immediately after finishing the first and last session. Assessment of physical side effects after exposure to VR by the Simulator Sickness Questionnaire (SSQ).
Adverse event tracking Up to 30 minutes during each session. Qualitative tracking of adverse events by patient observation scheme.
- Secondary Outcome Measures
Name Time Method Change from baseline in functionality of the upper limb Up to 10 minutes before the start of the first session and immediately after end of the last session. Assessment of changes in the functionality of the upper limb with the Fugl-Meyer upper extremity (FMUE) assessment. The FMUE Scale comprises 33 items, each scored on a scale of 0 to 2, where 0 = cannot perform, 1 = performs partially and 2 = performs fully.
Changes in pain levels from pre-to-post intervention session: Visual Analogue Scale Immediately before and after each session. Assessment of changes in pain using a Visual Analogue Scale ranging from 0 = no pain at all, to 100 = most pain imaginable.
