Gastric Biofeedback in Virtual Reality Shows Promising Results

Strategic Insights

— 2 min read

Researchers at the University of Fribourg in Fribourg, Switzerland, have conducted a study on gastric biofeedback in virtual reality (VR) and presented their findings in the journal Applied Psychophysiology and Biofeedback. According to the study, VR gastric biofeedback training has emerged as a promising tool to regulate gastric rhythm and alleviate symptoms associated with dysrhythmic gastric activity. The study, which involved 94 participants, tested a novel gastric biofeedback training in VR, comparing it to a 2D screen and a relaxation control group. The results showed a significant reduction in dysrhythmic gastric activity across sessions, improved ability to handle physical discomfort, and positive evaluations of the VR training.

Key Takeaways:

  • Gastric biofeedback using electrogastrography (EGG) has emerged as a promising tool to regulate gastric rhythm and alleviate symptoms associated with dysrhythmic gastric activity.
  • The study tested a novel gastric biofeedback training in VR and found a significant reduction in dysrhythmic gastric activity across sessions.
  • Participants reported an improved ability to handle physical discomfort and positive evaluations of the VR training.
  • Spatial presence, concentration, and alertness were higher in the VR group compared to the 2D group.
  • Further research is needed to better understand the underlying mechanisms and determine whether and how training success may relate to beneficial outcomes in clinical populations.
  • The study involved 94 participants divided into three groups: VR gastric biofeedback training, 2D screen training, and a relaxation control group.
  • The results showed a positive correlation between VR training and improved gastric activity, reduced dysrhythmic activity, and improved self-reported experiences.

Statistics:

  • 94 participants were involved in the study.
  • The study consisted of three groups: VR gastric biofeedback training (n=31), 2D screen training (n=31), and a relaxation control group (n=32).
  • Gastric activity showed a significant reduction in dysrhythmic activity across sessions (p < 0.05).
  • Participants reported an improved ability to handle physical discomfort over time (mean increase of 23%).
  • VR and 2D groups reported faster time perception and better concentration than controls (p < 0.01).
  • Spatial presence was higher in the VR group compared to the 2D group (p < 0.01).
