Biofeedback patients are trained to more effectively either use their muscles or quiet them, depending on the particular condition. Electrodes are applied to the skin to detect muscle tension, which is displayed on a computer screen. Patients receive feedback on the tension in their muscles and learn how to control their body’s response. They can also learn about their patterns of breathing and how they impact posture and pain. Biofeedback is used as a teaching tool and can increase the effectiveness of a self-management program for pain.
