Abstract

Fibromyalgia (FM) is characterized by widespread chronic pain and tenderness and is estimated to affect 2% of the general population. Non-pharmacological interventions including exercise are recommended as a first-line treatment for FM, however, movement-evoked pain often limits individuals' ability to participate in physical activity. The assessment of movement-evoked pain, in addition to resting pain, may enhance the individualization of clinical evaluation through inclusion of patient-specific tasks for those with widespread pain conditions. Therefore, the purpose of this analysis was to examine the contribution of pain (movement-evoked and resting) on the impact of FM as measured by the Fibromyalgia Impact Questionnaire Revised (FIQR) for patients prior to starting a course of physical therapy. Two hierarchical linear regression models were utilized to determine the contributions of movement-evoked pain (during a Sit and Stand test) and resting pain to the primary outcome of the FIQR while controlling for psychological factors (pain catastrophizing (Pain Catastrophizing Scale), depression (Patient Health Questionnaire-8), and anxiety (Generalized Anxiety Disorder-7)). Baseline data from 174 individuals with FM were included in the analysis. After controlling for psychological factors (adjusted R 2 =0.434), the addition of movement-evoked pain (adjusted R 2 =0.554, p<0.001) or resting pain (adjusted R 2 =0.571, p<0.001) improved the prediction of the FIQR. While the assessment of resting pain is common in clinical practice, the evaluation of movement-evoked pain may provide patient-specific information to personalize an exercise program that promotes physical activity for those with FM.
