Abstract： Objective： To observe the curative effect of the combination use of Shunshi Fuyang （seasonal invigoration of yang therapy） moxibustion and scrapping and eighteen-mode spine-strengthening exercises on chronic lumbar muscle strain in nurses. Methods：Nurses with chronic lumbar muscle strain working in Guangdong Provincial Hospital of Chinese Medicine from September 2022 to April 2024 were selected as the study subjects. They were divided into the control group and the observation group according to the random envelope method，with 38 cases in each group. The control group was treated with conventional moxibustion and scrapping combined with eighteen-mode spinestrengthening exercises， and the observation group was treated with Shunshi Fuyang moxibustion and scrapping and eighteen-mode spine-strengthening exercises. The clinical effects， and the changes in scores of Visual Analogue Scale （VAS） of low back pain and scores of Oswestry Disability Index （ODI） of lumbar function before and after treatment were compared between the two groups. Results：After treatment，the total effective rate was 97.37% （37/ 38） in the observation group and 78.95% （30/38） in the control group， the difference being significant （P＜0.05）. After treatment，the VAS scores of low back pain in the two groups were decreased when compared with those before treatment （P＜0.05），and the VAS score in the observation group was lower than that in the control group （P＜0.05）. After treatment，the ODI scores in the two groups were reduced when compared with those before treatment （P＜0.05） and the ODI score in the observation group was lower than that in the control group （P＜0.05）. Conclusion： The combination use of Shunshi Fuyang moxibustion and scrapping and eighteen-mode spine-strengthening exercises can relieve the degree of chronic lumbar muscle strain in nurses，improve the lumbar function and mitigate the symptoms of lower back pain.
