Activity-related pain may be a barrier to rehabilitation in patients
with chronic musculoskeletal disorders. This study investigated patients' reports
of increased pain during activity, and the association between such pain and
psychological factors and pain variables. METHOD: Questionnaires from 232 adults
with chronic musculoskeletal pain measured pain intensity, spread of pain and
pain duration. Pain during activity was assessed both on a 11-point Numeric
Rating Scale (NRS), and operationalised as a dichotomous measure, where
responders defined if they experienced pain during general activity and exercise.
Psychological factors were measured by the Hopkins symptom check list 25, the
Tampa Scale for Kinesiophobia and a subscale of the Arthritis Self-efficacy
Scale. Multiple and logistic regression were used to analyse associations between
increased pain during activity and associated variables. RESULTS: Increased pain
during activity was reported by 69% of participants. Fear of movement was a
significant factor for reporting increased pain during activity, both general
activity and exercise also in a subsample with low psychological distress. Other
significant factors were spread of pain and a low sense of self-efficacy.
CONCLUSION: Patients with high fear of movement, large spread of pain and low
self-efficacy were more likely to report increased pain during activity even in
the absence of psychological distress.
