PurposeWe investigated the recovery of the Japanese orthopedic association back pain evaluation questionnaire (JOABPEQ) scores and 6 min walk distance (6MWD) in patients after surgery for lumbar spinal stenosis and identified the items among 25 questions of JOABPEQ that showed recovery.MethodsA total of 227 patients (average age 71.5 years; SD: 7.5; 121 men) were included from a single center. The outcome measures were JOABPEQ, visual analog scale (VAS), and 6MWD and obtained preoperatively and at 1, 3, 6, and 12 months postoperatively. Mixed-model repeated measures were used to compare the variables at each time point between the surgery groups.ResultsThe JOABPEQ, VAS, and 6MWD scores generally improved at 1 month postoperatively compared with those obtained preoperatively, and some parameters further improved at 3 months. However, improvement in the lumbar spine dysfunction item of JOABPEQ was delayed, showing improvement at 3 months postoperatively for decompression surgery (average score: pre, 64.6; 3 months, 78.5) and 6 months postoperatively for fusion surgery (average score: Pre, 64.3; 6 months, 77.1). Responses to the individual JOABPEQ questions generally improved after surgery. No significant changes in lumbar spine dysfunction occurred in the fusion group.ConclusionOur results demonstrated the early postoperative recovery course of JOABPEQ and 6MWD. In the fusion group, significant changes in lumbar spine dysfunction started at 6 months postoperatively. These findings could help medical staff explain postoperative recovery to patients after lumbar spinal stenosis surgery and in their decision making regarding surgery.© 2024.
