The Doctor’s Remedy: Biofeedback for Stress

"A number of studies have found evidence that biofeedback devices can help reduce stress in hospital settings, though they have mostly been small and not always placebo-controlled. In a study at the Royal Free Hospital in London, researchers tested the effects of a computer biofeedback game on 40 patients with irritable bowel syndrome, a stress-related disorder. They found that it helped teach relaxation 'rapidly and effectively,' and reduced some symptoms. Another small study, published in the journal Clinical Pediatrics in 2010, found that a biofeedback video game that focused on breathing techniques benefited children with cystic fibrosis."
