Brief Summary: This prospective longitudinal study aims to identify modifiable predictors of return to work after back surgery
Detailed Description: Background Over the past decade the number of back surgeries in Belgium has substantially increased However even after an anatomically successful surgery 10 to 40 of the patients continue to report pain complaints causing personal suffering and an enormous economic burden The specific factors that can predict individual trajectories in postoperative pain recovery and work resumption are currently largely unknown
Aim The aim of this study is to identify modifiable predictors of work resumption after back surgery
Methods In this multisite prospective longitudinal study 300 individuals undergoing back surgery will be followed one-year post-surgery Prior to surgery the participants will perform a behavioral computer task to assess fear of movement-related pain and avoidance behavior and their generalization In addition participants will complete questionnaires to assess preoperative fear of movement-related pain avoidance behavior optimism expectancies towards recovery and work resumption and the duration and severity of the pain before the surgery Immediately after surgery as well as six weeks three months six months and twelve months postoperatively sustainable work resumption pain severity disability and quality of life will be assessed
Hypothesis The primary hypothesis is that generalization of fear of movement-related pain and avoidance behavior will negatively affect sustainable work resumption after back surgery Second the investigators hypothesize that generalization of fear of movement-related pain and avoidance behavior negative expectancies towards recovery and work resumption longer pain duration and more severe pain before the surgery will negatively affect work resumption pain severity disability and quality of life after back surgery In contrast positive expectancies towards recovery and work resumption and optimism are expected positively influence work resumption pain severity disability and quality of life
