I previously posted a discussion about the connection between Guided Imagery or Hypnosis and pain relief in children with recurrent abdominal pain (RAP). Guided Imagery had the most evidence in this area. Yoga has also been briefly been studied without a significant benefit for pain relief in this population (Reust & Williams, 2018). There is a strong component of the Mind/Body link in children with RAP. Biofeedback has been shown to be a good tool to use to show the effect of mindful relaxation on the physical body (Rakel, 2017). One exploratory study showed improvement for children using biofeedback showing that more research should be done as this may be a supportive treatment for children with RAP (Stern, Guiles, & Gevirtz, 2014).
