Biofeedback helps the client develop the ability to control certain physiological processes and is particularly useful with stress-related conditions or for conditions where there is muscle dysfunction. The biological signals produced by the body (heart rate, breathing rate, etc.) are monitored by sensors on the skin's surface and provide "feedback" to the patient. The practitioner helps the patient learn how to make voluntary changes in those biological functions and bring them under control.
During a Biofeedback session, a therapist will apply electrical sensors to different parts of your body. These machines can detect a person's internal bodily functions with far greater sensitivity and precision than a person can alone.

Biofeedback is a type of complementary and alternative medicine called mind-body therapy. Using feedback from a variety of monitoring procedures and equipment, a Biofeedback specialist will try to teach you to control certain involuntary body responses, such as brain activity, blood pressure, muscle tension, heart rate and more. By providing access to physiological about which the user is generally unaware, Biofeedback allows users to gain control over physical processes previously considered automatic.

Biofeedback is a treatment technique in which people are trained to improve their health by using signals from their own bodies. Physical therapists use Biofeedback to help stroke victims regain movement in paralyzed muscles. Psychologists use it to help tense and anxious clients learn to relax. Specialists in many different fields use Biofeedback to help their patients cope with pain.
