Our paper on VR-guided meditation and its effects on electroencephalograph (EEG) activity is now published and available to be viewed online at JMIR Biomedical Engineering journal.
A summary of what the purpose of this part of the research was summarized in an earlier blog post. We are very happy to have this paper published now. A great collaboration between SFU and UBC! Thanks again to Dr. Teresa Cheung and Henry Fu from the SFU School of Engineering Sciences for partnering with us on this research.
Findings suggest that distinct altered neurophysiological brain signals are detectable during VR-guided meditation, predominantly in terms of an increase in the power of the β and γ bands.
Changes in the α and θ bands were also identified, predominantly as a pattern in VR-guided meditation compared with the resting baseline, possibly reflecting the specific impact of visual activity during VR-guided meditation.
Some changes in coherence were also observed between the frontal and parietal and occipital cortices during VR-guided meditation. No significant association between pain scores and changes in EEG signals was observed.
Although this is an exploratory study, the results of this work clearly demonstrate the feasibility of EEG recording and subsequent data processing and analysis during VR experiences in patients using modern VR head-mounted displays.

We wanted to provide an update to all blog readers on the progress of our study.
Over the summer, we have finished conducting the analysis for a pilot study on the effect of VR-guided meditation on brain waves using the electroencephalograph (EEG). Our main objective in this sub-study is explore if VR-guided meditation exposure has any specifically identifiable characteristics on the neurological activity in the brain through an EEG scan. We enrolled ten participants who had positive experience as a part of the VR arm of the main clinical trial. Participants undertook an EEG brainwave scan, whilst undertaking a VR experience in their home under the supervision of a trained research assistant.
We partnered with Dr. Teresa Cheung, a physicist and medical imaging scientist, from the Simon Fraser University’s ImageTech lab, for this portion of the study. As this was the first use of EEG recording with patients using VR for pain management, this required the use of novel experimental and analytical approaches, as well as a significant amount of data cleaning and pre-processing prior to analysis, and the use of multiple statistical analytics.
The study data analysis has now concluded and we have finalized a paper for publication in November, 2020. Once this study is published, we will share our findings of the published paper on our blog. We hope you will look forward to reading this paper once it is in the press!
We conducted two mini focus groups addressing the topics of participants’ experiences and perceptions of the use of VR in August, 2018 and March, 2019. The results from the focus groups have now been published.
We found five major thematic categories and 23 sub-categories emerged in the analysis process reflecting the participants’ narrative.
Similar to other research, we found mixed results in the use of adjunctive VR therapy to manage chronic cancer pain, although a majority of respondents found it to be beneficial.
Our results confirm that pain management is a highly complex and individualized process. For maximum efficacy, it is recommended that future designs of VR interventions engage pain patients in the design process to ensure maximum efficacy of experiences to with individuals’ preferences.
During this uncertain time, non-essential surgeries like knee and hip replacements are on hold. And so is the hands-on training for surgical residents in the orthopedics program at the University of British Columbia.
But those residents will soon be able to practise doing surgeries using Precision OS, a cutting-edge virtual reality program created by Dr. Danny Goel, an orthopedic surgeon at Burnaby General Hospital. The technology is already being used by orthopaedic residents at the University of Connecticut, and will roll out at UBC in mid-May.

We are certainly looking forward to all the ways VR can be used to advance medical education both during and perhaps after we return to the “new normal”.
Scientists from Imperial College London have found that using virtual reality headsets could combat increased sensitivity to pain, by immersing people in scenes of icebergs, frigid oceans and sprawling icescapes.
According to the researchers, the findings add to the growing evidence for the potential of VR technology to help patients with chronic pain.
Beyond the distracting effect, they think immersing patients in VR may actually trigger the body’s own inbuilt pain-fighting systems — reducing their sensitivity to painful stimuli and reducing the intensity of ongoing pain.

ProjectDR was developed by researchers at the University of Alberta.
There is other medical imaging software that exists but ProjectDR is unique because it allows doctors to view a patient’s internal anatomy within the context of the body as they move around and rotate in 3D space. The researchers plan to test the technology in operating rooms and surgery simulations.
Back in November, 2017, Dr. Bernie Garrett gave a presentation at the Uniquely UBC: Good for You Games event. Participants were also able to test out the VR environments the research team has prepared for the event.
