Abstract：Objective To investigate the clinical effect of semiconductor laser and intermediate frequency pulse electrotherapy on patients with sciatica caused by lumbar disc herniation. Methods A total of 82 patients with lumbar disc herniation and sciatica who were hospitalized in the Department of Rehabilitation, the First People’s Hospital of Suzhou City in Anhui Province from April 2018 to December 2019 were selected as the research objects. According to the order of admission, they were randomly divided into 42 cases in the control group and 42 cases in the interventim group. The control group was given intermediate frequency pulse electric therapy, and the intervention group was added with semiconductor laser treatment on the basis of the control group. The pain, inflammatory factors and clinical efficacy of the two groups before and after intervention were compared. Results The total scores of pain rating index (PRI), visual analog scale (VAS), present pain index (PPI) and simple pain questionnaire (McGill) in the two groups after intervention were lower than those before intervention, and the total scores of PRI, VAS, PPI and McGill scores in the intervention group were lower than those in the control group, with statistical significant differences (all P ＜ 0.05). After intervention, serum levels of β-endorphin (β-EP) were significantly incresed and tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the two groups were significantly reduced after intervention, and β-EP in the intervention group was higher than that in the control group, while TNF-α and IL-6 in the intervention group were lower than those in the control group, with statistical significant differences (all P ＜ 0.05). The effective rate of the intervention group was higher than that of the control group, and the difference was statistically significant (P ＜ 0.05). Conclusion Intermediate frequency pulsed electricity combined with semiconductor laser has a significant clinical effect in treating lumbar disc herniation and sciatica, which is worthy of clinical application.
