[Purpose] This study aimed to examine gradual changes in and relationships among
preoperative and 3-month postoperative endpoints in patients with lumbar degenerative
disease. [Participants and Methods] The study included 160 diagnosed with lumbar
degenerative diseases who underwent surgery. Patients were divided into two groups: “good
progress” and “recrudescence”. Changes in the Japan Orthpedics Associations (JOA) score,
JOA back pain evaluation questionnaire (JOABPEQ), and numeric rating scale (NRS)
preoperatively and 3 months postoperatively, and their associations, were analyzed.
[Results] Differences were found in preoperative NRS for low back pain, JOA score (other
findings) at 3 months postoperatively, and NRS for low back pain at 3 months
postoperatively. The causal analysis yielded paths for “daily life”, “pain”, and
“social/psychological aspects”, starting with “lumbar spine disorders”. [Conclusion] The
subjective symptoms, objective findings, lumbar spine dysfunction, gait dysfunction, and
numbness at 3 months postoperatively yielded relevant information regarding the
participants activities of daily living, pain, and social and psychological aspects,
providing a perspective for monitoring postoperative patients.
