Pain-related fear, Generalization and Occupational Health in Low Back Pain

Previous studies indicated that about 20% of the individuals undergoing back surgery are unable to return work three months to one year after surgery. The specific factors that predict individual trajectories in postoperative pain, recovery, and work resumption are however largely unknown. The aim of this doctoral research is to identify modifiable predictors of work resumption after back surgery. Therefore, the researchers will conduct a prospective, multisite study in which individuals with radicular pain, who are undergoing a back surgery, are followed until one year post-surgery. The primary hypothesis is that generalization of fear of movement-related pain and avoidance will negatively affect recovery and work resumption. To assess generalization of fear of movement-related pain and avoidance behavior, a computer-based paradigm was developed and validated. Besides the longitudinal study, an Ecological Momentary Assessment study will be conducted to gain more insight in the dynamic relations between pain-related fear and avoidance. At last, a systematic review will be conducted to gain more knowledge about the cognitive and behavioral predictors that promote or impede (functional) recovery and work resumption after back surgery.
