Abstract Objective: To investigate the effect of posterior medial branch of spinal nerve block on pain relief, ODI index score and JOA score in patients with low back pain. Methods: The selected study objects are 96 patients with low back pain from February 2016 to February 2020. A simple random grouping method is adopted through the random number table. The patients were divided into control group (given conventional treatment) and observation group (given posteromedial spinal nerve block surgery), each with 48 cases, and the VAS score and ODI index score, low back muscle extension activity (ROM), isometric muscle strength (IMS), JOA score, quality of life were observed and evaluated. Results: After 1 week, 4 weeks, and 8 weeks of treatment, the VAS score and ODI index score of the observation group were lower than those of the control group, while the scores of ROM, IMS, subjective symptoms, clinical signs, limitations of daily life, physical health, mental health, and social relationship, independence and environmental factors were higher than those of the control group (P<0.05). Conclusion: The posterior medial branch of spinal nerve block can not only improve lumbar spine function, but also relieve pain in patients with low back pain, and has high application value.
