Chronic pain and depression most likely have a bidirectional association: depression is a predictor of persistent pain and pain is a predictor of the persistence of depression. Depression and anxiety share the same psychological pathways as pain and can have a reciprocal effect on each other (de Heer E, 2014). As the above study stated, rather to say the relationship between anxiety and pain is a simple unidirectional causality, a vicious circle is a more accurate description. However, the limitation of the study mainly focus on the reliability of the data as they are based on self-report, which may have the possibility of over-reporting or un-reporting the chronic pain level and/or anxiety disorder. Yet, it is certain that chronic pain is not purely biological but also has psychological …show more content…

In other words, biofeedback only provides the signals of the physiological conditions and makes one be aware of it. The actual reduction of pain is done by the patients themselves as a result of trying to relax their body tension or manipulate their symptoms. As the basic principle of biofeedback stated, “Feedback makes learning possible”
Based on above, the following statement can be concluded: First, there is an interaction between mind and body, where the chronic pain is caused by the psychological symptom, and in contrast, psychological thoughts, or will, are able to influence physiological condition. Second, biofeedback is essentially a technical tool that provides physical feedback to the patients. Third, it cannot do anything to the chronic pain without the actual effort of the patient to respond to the
