Virtual Reality–Guided Meditation for Chronic Pain in Patients With Cancer: Exploratory Analysis of Electroencephalograph Activity

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.  Thanks again to Dr. Teresa Cheung and Henry Fu from the SFU School of Engineering Sciences for partnering with us on this research.

Key Takeaways:

  • 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.
