Objective To explore the clinical efficacy of preoperative precise rehabilitation on endoscopic spinal decompression （Endo-LOVE） for lumbar spinal stenosis （LSS）. Methods A retrospective study was con⁃ ducted among 52 patients with Endo-LOVE from January 2020 to April 2022. The patients were equally divided into observation group and control group, treated with precision rehabilitation and traditional rehabilitation accord⁃ ing to the different rehabilitation patterns, respectively. The two groups were compared in terms of the score by Visual Analogue Scale （VAS）, Oswestry Disability Index （ODI） and JOA scores as well as the ratio of left and right supporting phases in gait parameters before the operation, 7 days and 3 months after the operation. Results There were no serious surgical complications in all patients. The VAS and ODI scores 7 days and 3 months after the operation were significantly lower （P < 0.05） and the JOA score and the ratio of left and right supporting phases were significantly higher than before the operation（P < 0.05）. The indexes of the observation group were statisti⁃ cally significantly different with those of the control group 7 days and 3 months after the operation （P < 0.05）. Conclusion Preoperative precise rehabilitation in Endo-LOVE for LSS can relieve postoperative residual pain, improve walking function, reduce the degree of lumbar dysfunction, improve the ability of daily living, and shorten the rehabilitation period. It is of value for clinical application. [ABSTRACT FROM AUTHOR]
