The goal of biofeedback is to help individuals develop control over physiological processes to help pain and anxiety as well as a variety of other symptoms. In biofeedback, we use highly sensitive electronic instruments to monitor, and provide feedback about physiological information to the client. Common specific goals of biofeedback involve monitoring and training control over physical features such as temperature, and sweat gland activity. Biofeedback has been shown to be helpful for a variety of problems and conditions, including anxiety, ADHD, chronic pain and headaches, sleep difficulties, and traumatic brain injury. Quite often, biofeedback is not used alone but rather in combination with individual therapy and invivo desensitization treatment if applicable.
