Conclusions
degenerative disc disorder, LBP
Our study demonstrated that preoperative fear of movement was significantly associated with postoperative SB in patients with LBP and degenerative disc disorder undergoing lumbar fusion surgery. This finding underscores the potential benefits of providing preoperative screening of pain-related psychological factors, including fear of movement, to identify patients who are suitable for preoperative interventions aimed at a healthier postoperative movement behaviour and improved health.
