Biofeedback may be defined as providing information about a body process or function that we are not normally aware of. For example, temperature biofeedback provides immediate auditory and/or visual feedback for 1/1000 of a degree changes. As a clinical procedure, biofeedback has a sound scientific foundation beginning in the 1960's. Biofeedback is easy and fun to learn, and does not have any adverse side effects. We provide biofeedback for vision problems using the AVT combined with brain wave (EEG), muscle (EMG), and temperature biofeedback. Because of the general beneficial effects of brain wave biofeedback, it is also known as neurotherapy. More information about biofeedback and neurotherapy can be found at the MEDIA page.
