Fear of Movement Is Related to Low Back Disability During a Two-Year Period in Patients Who Have Undergone Elective Lumbar Spine Surgery.

Abstract

To evaluate change in fear of movement and the relationship of fear of movement and pain intensity to low back disability and general health-related quality of life over a 2-year period. Consecutive patients scheduled for lumbar spine surgery were included. In addition to clinical background variables, back pain intensity, fear of movement, low back disability, and general health-related quality of life were assessed at baseline, 1 year, and 2 years after surgery. Linear mixed-effects models were used to analyze data. In total, 348 patients were included in the final analyses. There was a significant reduction in fear of movement and a significant interaction between fear of movement and low back disability across assessments, showing that greater levels of fear of movement were related to greater levels of disability over the 2-year period. Similarly, greater levels of back pain intensity were related to lower levels of general health-related quality of life during this period. We found that greater levels of fear of movement were related to greater levels of low back disability, following lumbar spine surgery, in a longitudinal study. This shows the need to address fear of movement in prehabilitation/rehabilitation pre- or postsurgically to improve health outcomes for patients who undergo lumbar spine surgery.
