Originating in the 1960s, this process informs a patient about their physiological information in an attempt to be able to gain control over reactions that were once thought of as involuntary.
Listed below are a few methods used in biofeedback:
Electromyograph – EMGs are one of the most common ways to administer biofeedback treatment. The EMG creates muscle tension so that the patient will be able to recognize it and then consequently know how to control it. This is often used to relieve backaches, neck pain, headaches and migraines.
Feedback thermometer – This device measures the body temperature in the skin that signals stress.
Electrodermograph – Sensors will measure sweat gland activity that can indicate anxiety. This treatment is used in polygraph testing.
Electroencephalograph – EEGs measure brain waves that can correspond with wakefulness, relaxation, calmness and depth of sleep.
Photoplethysmograph – PPGs measure heart rate, blood flow and heart rate variability. By gathering this information, a breathing pattern can be found that can regulate this information.
