Biofeedback is a therapy that can help children with many types of physical symptoms as well as with emotional difficulties. This type of training uses a specialized computer program and sensor connected to the child’s body to measure breathing, heart rate and other physiologic processes. The information is then analyzed and shown to the child to teach him/her how to control these processes. By doing this, the child is taught to turn on the part of the nervous system that creates calm and may decrease the awareness of pain. When controlling breathing, for example, children are taught to notice changes in how their body feels so that they can learn to create the same feeling on their own at home. In general, 6 to 10 weekly sessions are sufficient to train a child to master these skills. Biofeedback has been used for several decades to help children and adults with chronic pain, anxiety, headache and many other health issues.
