Biofeedback is the process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at will.

Biofeedback is a minimally invasive chronic pain treatment that is also used for a variety of conditions. Biofeedback was developed based on the concept that the way individuals think can influence processes in the body and that this may occur consciously or subconsciously. For instance, painful experiences can put extra stress on the body as well as the mind. Furthermore, stress is associated with physiological changes in the body such as muscle tension and an increase in blood pressure, respiration, and heart rate. Symptoms such as muscle tension or heightened respiration can exacerbate pain and this process becomes a feedback loop that makes it difficult for an individual to experience long-term pain relief without some form of intervention. Biofeedback provides an opportunity to break the stress-pain cycle.
