It is known that chronic fatigue syndrome (CFS) patients often present unhelpful pain beliefs / behaviors, such as catastrophic thinking, depressive thoughts, passive coping strategies and fear of movement or kinesiophobia. Several of these beliefs and personality traits could potentially enhance pain perception, a process known as cognitive emotional sensitization.
Therefore we studied the role of several psychosocial determinants of chronic pain in CFS patients. Pain catastrophizing, depression, kinesiophobia and several passive coping styles were related to pain, but catastrophizing and depression were the main predictors for pain measured at the same time and measured 6 to 12 months later in patients with CFS with chronic widespread musculoskeletal pain. Depression and catastrophizing were able to predict 23% of the pain variance 6 to 12 months later.
Since these factors may be at the basis of chronic pain and act as important therapy barriers in CFS it is important to consider these psychosocial factors in the approach of CFS patients experiencing chronic widespread pain. The therapeutic approach of these patients is indeed a real challenge, because there is not a clear source of nociception and complaints are widespread and general. Furthermore, CFS patients often present with low tolerance or fear to certain physical therapy modalities (e.g. exercise, painful manual techniques, etc.) and those typical unhelpful pain cognitions / behaviors. Therefore, besides or before addressing the physical components, the treatment approach of these patients should account for these cognitive and emotional aspects.
The latter may in fact be the first point of interest in the therapeutic approach, since these factors are related to the pain and may be important therapy barriers. A possible tool to influence these psychological factors and in consequence eventually pain is providing pain education, which has already been shown to be efficacious in reducing pain catastrophizing in CFS patients.
