Kinesiophobia and maladaptive coping strategies prevent improvements in pain catastrophizing following pain neuroscience education in fibromyalgia/chronic fatigue syndrome : an explorative study

Many patients with chronic fatigue syndrome(CFS) and/or fibromyalgia(FM) have little understanding of their condition, leading to maladaptive pain cognitions and coping strategies. These should be tackled during therapy, for instance by pain neurophysiology education (PNE). Although positive effects of PNE are well-established, it remains unclear why some patients benefit more than others. This paper aims at exploring characteristics of patients responding poor to PNE to further improve its effectiveness. Data from two RCT's were pooled to search for baseline predictors. Subjects (n = 39) suffering from CFS/FM, as defined by the American College of Rheumatology, underwent PNE treatment. The Pain Catastrophizing Scale (PCS); Pain Coping Inventory (PCI); and Tampa Scale of Kinesiophobia (TSK) were defined as outcome measures. There was a significant negative relationship between baseline TSK and the change in both PCS total score (r = -0.584; p < 0.001) and PCS rumination (r = -0.346; p < 0.05). There was a significant negative relationship between the change in PCS total score and baseline PCI worrying (r = -0.795; p < 0.001) and retreating (r = -0.356; p < 0.05). FM/CFS patients who tend to worry allot about their pain and with high levels of kinesiophobia are likely to experience less reductions in catastrophizing following PNE. It seems that PNE alone is insufficient to reduce catastrophic thinking regarding pain, and supplementary treatment is needed.
