Reductions in movement‐associated fear are dependent upon graded exposure in chronic low back pain: An exploratory analysis of a modified 3‐item fear hierarchy.

Objective: To explore the effectiveness of a modified fear hierarchy on measuring improvements in movement‐associated fear in chronic low back pain. Methods: A modified 3‐item fear hierarchy was created and implemented based on principles of graded exposure. This study was an exploratory analysis of the modified 3‐item fear hierarchy from a larger clinical trial data set. Both groups received pain education and exercise, either bodyweight or strength training. Both groups performed item one on the hierarchy, the squat. Only the strength training group performed item 2, the deadlift. Neither group performed item 3, the overhead press. Analysis of Covariance and stepwise linear regression were used to explore results. Results: Improvement in movement‐associated fear was conditional upon graded exposure. Both groups improved in the squat movement (p ≤ 0.05), which both performed. Only the strength training group improved in the deadlift (p ≤ 0.01), and neither improved in the overhead press (p ≥ 0.05). Conclusion: Reductions in movement‐associated fear are conditional upon graded exposure, based on the use of a novel modified 3‐item fear hierarchy. Further research is needed to understand the utility of this tool in a patient‐led approach to co‐designing a graded exposure‐based intervention. [ABSTRACT FROM AUTHOR]
