Abstract：Objective：To observe the clinical effect of Bugan Jianyao Decoction combined with suspension core muscle training on chronic nonspecific low back pain （NLBP） of liver-kidney deficiency type. Methods： A total of 200 cases of patients with chronic NLBP of liver-kidney deficiency type， treated at Luoyang Orthopedic- Traumatological Hospital of Henan Province/Henan Provincial Orthopedic Hospital from January 2021 to January 2024， were selected and divided into the combination group and the training group，with 100 cases in each group. The training group was treated with suspension core muscle training，and the combination group was additionally treated with Bugan Jianyao Decoction based on the treatment of the training group. Both groups were treated for four weeks. The clinical effects， traditional Chinese medicine（TCM） syndrome scores， mean frequency （MNF） of core muscles in different positions （maximum extension， maximum flexion）， oxidative stress indexes [superoxide dismutase （SOD）， malondialdehyde （MDA）， catalase （CAT）]， Oswestry Disability Index （ODI） scores， and Visual Analogue Scale （VAS） scores of pain were compared between the two groups. Results：After four weeks of treatment，the total effective rate was 94.00% （94/100） in the combination group， higher than that of 78.00% （78/100） in the training group （P＜0.05）. The main and secondary symptom scores，and the total TCM syndrome scores in the two groups were decreased when compared with those before treatment （P＜0.05）， with the combination group showing lower scores than the training group （P＜0.05）. The MNF values of the erector spinae，multifidus muscle，and rectus abdominis in both maximum flexion and extension positions in the two groups were increased when compared with those before treatment （P＜0.05），with the combination group showing higher MNF values than the training group （P＜0.05）. The levels of SOD and CAT in serum in the two groups were increased when compared with those before treatment （P＜ 0.05），with the combination group showing higher levels than the training group （P＜0.05）. Serum MDA levels in the two groups were decreased when compared with those before treatment （P＜0.05），with the combination group showing lower level than the training group （P＜0.05）. The scores of ODI and VAS in the two groups were reduced when compared with those before treatment （P＜0.05）， with the combination group showing lower scores than the training group （P＜0.05）. Conclusion： Bugan Jianyao Decoction combined with suspension core muscle training has a significant curative effect in treating chronic NLBP of liver-kidney deficiency type， which can effectively alleviate clinical symptoms and improve core muscle group function. Its action mechanism can be related to the alleviation of oxidative stress damage.
