Kinesiophobia contributes to pain-related disability in breast cancer survivors: a cross-sectional study

PURPOSE: Pain is one of the most prevalent problems reported by breast cancer survivors. As this long-lasting complication can result in disabilities on all different domains of functioning, we aimed to clarify the contribution of different factors (pain-related factors, psychosocial factors, and fatigue) to pain-related disability in female breast cancer survivors. METHODS: Seventy women who had completed their primary breast cancer treatment were included in this cross-sectional study. The following outcome measures were evaluated as independent variables for their contribution to pain-related disability (measured by the Pain Disability Index, with a maximum score of 70): pain intensity, self-reported symptoms of central sensitization, fatigue, illness beliefs, pain catastrophizing, and kinesiophobia. At first, bi- and multivariable regression methods were conducted. Secondly, a stepwise regression analysis was performed to determine the explained variance of the PDI. RESULTS: Mean score on the PDI was 16 at 4.5 years post-surgery. Multivariable regression analysis revealed higher levels of kinesiophobia as the main contributor to pain-related disability. Ultimately, stepwise regression showed that up to 40% of variance in pain-related disability could be explained by kinesiophobia, negative perceptions related to illness consequences, and pain catastrophizing. CONCLUSION: This study shows that breast cancer survivors portray moderate self-reported pain-related disability. Kinesiophobia emerged as the main contributor to pain-related disability at this time point, which could shine a light on the improvement of treatment modalities for pain management in this population.
