Objective To observe the effects of extracorporeal shock wave therapy (ESWT) combined with kinesio taping (KT) on chronic non-specific low back pain (CNLBP). Methods CNLBP patients who visited the Department of Rehabilitation Medicine, the Second Affiliated Hospital of Nantong University between January 2021 and January 2022 were selected. The included patients were divided into ESWT group, KT group, and combined treatment group using a random number table method. All patients received conventional rehabilitation. The ESWT group was treated with ESWT, the KT group was given KT therapy, and the combined treatment group were treated with ESWT and KT with the same treatment frequency as before. Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), MOS 36-item Short form Health Survey (SF-36) and Self-rating Anxiety Scale (SAS) were used to evaluate pain severity, lumbar spine function, quality of life, and anxiety status in all groups before and 4 weeks after treatment, respectively. Results A total of 85 patients were included. Among them, there were 29 cases in the ESWT group, 28 cases in the KT group, and 28 cases in the combined treatment group. There was no adverse event in any group. The intra-group comparison results showed that the VAS, ODI, and SAS scores of the three groups after 4 weeks of treatment were lower than those before treatment (P<0.05), while the SF-36 scores in all dimensions were higher than those before treatment (P<0.05). Before treatment, there was no statistically significant difference in VAS, ODI, SAS, or SF-36 scores among the three groups (P>0.05). After 4 weeks of treatment, there were statistically significant differences in VAS, ODI, SAS, and SF-36 scores among the three groups (P<0.05). The results of multiple comparisons between groups showed that the VAS scores of the ESWT group and the combination therapy group were lower than those of the KT group (P<0.05); the ODI scores of the combination therapy group were lower than those of the ESWT group and the KT group (P<0.05); the SAS scores of the combination therapy group were lower than those of the KT group (P<0.05); the SF-36 scores of each dimension were compared in pairs among the three groups, and the differences were statistically significant (P<0.05); there was no statistically significant difference in pairwise comparison of other indicators between groups (P>0.05). Conclusion ESWT combined with KT can more effectively improve the pain and lumbar spine function of patients with CNLBP, and improve the quality of life of patients.
