Objective To explore the clinical efficacy of combined neck-spine synchronous traction and electroacupuncture in the treatment of cervical spondylotic radiculopathy (CSR) and its impact on cervical function. Methods By using a retrospective analysis method, the clinical data of 134 patients with CSR who were admitted to Fuan People’s Hospital from January 2023 to December 2024 were selected. According to the treatment methods, they were divided into the control group (conventional cervical traction combined with electroacupuncture treatment, n＝64) and the observation group (neck-spine synchronous traction combined with electroacupuncture treatment, n＝70). Both groups underwent efficacy evaluation 2 weeks after treatment, and the clinical efficacy, visual analogue scale (VAS) score, neck disability index (NDI) score, and cervical range of motion were compared between the two groups. This study was followed up for 6 months, and the recurrence rate at the follow-up was compared between the two groups. Results After treatment, the VAS scores and NDI scores of the observation group were lower than those of the control group (all P＜0.05), the total effective rate was higher than that of the control group (P＜0.05), and the improvement in cervical joint mobility was better than that of the control group (P＜0.05). At the follow-up, the recurrence rate of the observation group was 5.71%, which was lower than the 15.62% of the control group (P＜0.05). Conclusion Combined neck-spine synchronous traction and electroacupuncture treatment can effectively relieve the pain of CSR patients and significantly improve cervical function. The clinical efficacy is obvious, and it has a positive effect on reducing the recurrence rate. It is suitable for clinical promotion and application.
