However, recurring LDH\/LBP following spinal endoscopy radiofrequency is a significant problem. Paravertebral musculature plays a crucial role in spine stability and motor function, and the purpose of the present study was to identify whether patients\u2019 baseline lumbar muscular electrophysiological function could be a predictor of recurring LDH\/LBP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a prospective follow\u2010up and case\u2010control study focusing on elderly patients with LDH who were treated in our department between January 1, 2018, and October 31, 2021. The end of follow\u2010up was recurring LBP, recurring LDH, death, missing to follow\u2010up or 2\u2009years postoperation. The surface electromyography test was performed before the endoscopy C\u2010arm radiofrequency (ECRF) operation to detect the flexion\u2013relaxation ratio (FRR) of the lumbar multifidus (FRR<jats:sub>LM<\/jats:sub>) and the longissimus erector spinae (FRR<jats:sub>ES<\/jats:sub>), and the other baseline parameters included the general characteristics, the visual analogue scale, the Japanese Orthopaedic Association score, and the Oswestry Disability Index.
