BRAIN TRAINING explains a practice"open focus" which When learned and utilized helps manage Chronic pain. This methodology is an outgrowth of biofeedback introduced in the 1970s. It is based on proven research and clinical practice. The book is comprised of case studies, exercises as well as a variety of disciplines from different scientific fields to explain the process. It is a simple but powerful guide that in my opinion stands up next to meditation and mindfulness as a means to train the brain to use its resources to manage pain. I highly recommend it to anyone who suffers from chronic pain. Thanks Dr Fehmi.
