Abstract: Objective To explore the application effect of straight leg elevation training and early lumbar and dorsal core muscle strength training in patients undergoing vertebroplasty. Methods A total of 116 patients who were underwent vertebroplasty at the Third People's Hospital of Jinan City, Shandong Province from January 2023 to December 2023 were selected, and randomly divided into the study group (n=58) and the control group (n=58). The control group was received routine rehabilitation training, while the study group was received straight leg elevation training and early lumbar and dorsal muscle nucleus myocardial strength training. The spinal function, pain level, balance and exercise ability, and daily living ability in both groups were compared. Results Before intervention, in the Oswestry Disability Index (ODI) and Japanese Orthopaedic Association (JOA) scores in both groups, there was no statistically significant difference (P>0.05). After intervention, in comparison of the control group, the ODI scores of the study group were lower, and JOA scores were higher, with statistically significant differences (P<0.05). Before intervention, there was no statistically significant difference in the visual analog scale (VAS) scores in both groups (P>0.05). After intervention, in comparison of the control group, the VAS score of the study group was lower, and the difference between the groups was statistically significant (P<0.05). Before intervention, there was no statistically significant difference in the scores of the Berg balance scale (BBS) and the lower section of the Fugl Meyer assessment (FMA-LE) in both groups (P>0.05). After intervention, in comparison of the control group, the BBS and FMA scores of the study group were higher, with statistically significant differences (P<0.05). Before intervention, there was no statistically significant difference in the Barthel index (BI) in both groups (P>0.05). After intervention, in comparison of the control group, the study group was higher, and the difference was statistically significant (P<0.05). Conclusion The combination of straight leg elevation training and early lumbar and dorsal core muscle strength training can improve spinal function, reduce pain, enhance balance and mobility, and improve daily living abilities in patients undergoing vertebroplasty.
