This study aims to develop an Internet-based Cognitive Behavioral Therapy protocol for core muscle training, based on an understanding of factors impeding postoperative core muscle training in lumbar surgery patients. The protocol is designed to reconstruct patients' cognition, eliminate adverse behaviors, and promote healthy behaviors such as core muscle training among LDH patients. The ultimate objectives are to alleviate postoperative pain, enhance lumbar stability, and facilitate disease rehabilitation in patients following lumbar surgery.
