Biofeedback is a technique in which people learn how to gain control over internal body processes that normally occur involuntarily, such as blood pressure, heart rate, muscle tension, and skin temperature.
Biofeedback is primarily used for high blood pressure, migraine, tension headache, chronic pain, and urinary incontinence.
Of the different types of biofeedback, thermal feedback (which measures skin temperature) and electrodermal activity feedback (which uses a probe that responds to sweat) may be more effective than direct blood pressure feedback or electromyography (EMG), which measures muscle tension.
