Relaxation Therapy involves learning skills such as deep breathing, progressive muscle relaxation and visual imagery. The goal is to use the power of the mind and body to achieve a sense of relaxation. Practicing relaxation skills in therapy sessions and between therapy sessions aids in decreasing stress, anger, anxiety, difficulties in going to sleep, etc. Sometimes peripheral biofeedback will be included as an additional relaxation technique. By providing the patient with immediate feedback on their breating and heart rate, the patient learns to decrease physical signs of stress. This feedback can be in the form a videogame and/or a graph.
