Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Description of intervention(s) / exposure
Virtual reality brain-computer interface (VR-BCI) Training
Seven healthy, right-handed volunteers (2 females, aged 24-40) participated in this study. None had any medical conditions like pregnancy, claustrophobia, drug addiction, or neurological diseases that could interfere with the tasks. Each person completed 15 training sessions, held on different days, with no more than three sessions per week.
All sessions were administered by one of the researcher from the team. All participants received exactly the same tasks throughout the intervention.

The study followed ethical guidelines, was approved by Griffith University’s research ethics board, and all participants gave written consent before joining.

During each session, participants sat comfortably while wearing an electroencephalogram (EEG) headset to measure brain activity and a virtual reality (VR) headset for the tasks. They practiced two types of mental exercises: imagining themselves walking or relaxing. Each session included three phases: calibration, cued-online with feedback, and using the system freely without cues. Breaks of 1-3 minutes were given between phases, depending on the participant's readiness. Each session, including setup, took about an hour and was conducted in Griffith University’s Physiotherapy Laboratory (G02_1.17).

Efficacy
Statistical methods / analysis
The number of participants for this study was determined based on prior studies in brain-computer interface (BCI) research and virtual reality (VR)-based rehabilitation, which typically involve small sample sizes (5–10 participants) for exploratory and longitudinal investigations. The focus was on feasibility and observing significant trends in learning motor imagery (MI) control over multiple sessions. Participants were recruited to represent a sufficient sample for detecting individual changes in BCI performance and sensorimotor neuromodulation through repeated measures analysis.
