Application of Chain Management Based on the IMB Model in Patients With Kinesiophobia Following Lumbar Fusion Surgery

This study aims to investigate the application effect of chain management based on the Information-Motivation-Behavioral Skills (IMB) model in patients with kinesiophobia after lumbar fusion surgery. The intervention is designed to provide IMB model-based chain management, with routine nursing intervention as the control, and to evaluate the degree of kinesiophobia (TSK), pain intensity (NRS), lumbar function (ODI), and spinal posture indicators (trunk deviation angle, pelvic torsion angle, and the sum of the maximum left and right vertebral rotation angles) at different time points before and after the intervention. The ultimate objectives are to reduce the level of kinesiophobia, relieve pain, improve lumbar stability and lumbar function, and promote postoperative rehabilitation in patients after lumbar fusion surgery.

Inclusion Criteria: * Confirmed diagnosis of degenerative spinal disease * First-time treatment with posterior lumbar decompression and interbody fusion, with stable vital signs after surgery * Age ≥18 years * TSK (Tampa Scale of Kinesiophobia) score \>37 within 48 h after surgery Exclusion Criteria: * Concomitant other lumbar spine-related medical history and inability to perform functional exercises * Malignancy or concomitant damage to important organs such as the brain, heart, and lungs * Cognitive impairment
