Biofeedback is the process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at will. Some of the processes that can be controlled include brainwaves, muscle tone, skin conductance, heart rate and pain perception. In biofeedback, you are connected to electrical sensors that help you receive information (feedback) about your body (bio).
Biofeedback may be used to improve health, performance, stress, and anxiety, after being injured as a result of personal injury trauma. Eventually, these changes may be maintained without the use of bio-feedback equipment.
Biofeedback has been found to be effective for the treatment of headaches and other post-traumatic stress from many different types of personal injuries.
