Cervical spondylotic radiculopathy (CSR) is the most commonly encountered cervical spine disorder. Cervical manipulation has been demonstrated as an effective therapy for patients. However, the mechanisms of manipulations have not been elucidated. A total of 120 cervical spondylotic radiculopathy patients were divided into the "three-dimensional balanced manipulation" treatment group (TBM group) and control group randomly. The control group was treated with traditional massage; the TBM treatment group was treated with "three-dimensional balanced manipulation" based on traditional massage. The symptoms and clinical efficacy of the patients were compared before and after treatment for one month. A three-dimensional finite element model was established. The mechanical parameters were imported to simulate TBM, and finite element analysis was performed. The results showed that the total effective rate was significantly higher in the TBM group compared with the control group. The biomechanical analysis showed the vertebral body stress was mainly distributed in the C3/4 spinous processes; the deformation mainly concentrated in the anterior processes of the C3 vertebral body. The intervertebral disc stress in the C3~C7 segment was mainly distributed in the anterior part of the C3/4 intervertebral disc, and the deformation extends to the posterior part of the C3/4 nucleus pulposus. In summary, these data are suggesting that TBM was effective in CSR treatment. The results of the finite element model and biomechanical analysis provide an important foundation for effectively avoiding iatrogenic injuries and improving the effect of TBM in the treatment of CSR patients.
颈椎病性神经根病（CSR）是最常见的颈椎疾病。颈椎推拿已被证明是一种有效的治疗方法。然而，推拿的机制尚未阐明。将 120 例颈椎病性神经根病患者随机分为“三维平衡推拿”治疗组（TBM 组）和对照组。对照组采用传统按摩治疗；TBM 治疗组在传统按摩的基础上采用“三维平衡推拿”治疗。比较两组患者治疗前后一个月的症状和临床疗效。建立三维有限元模型。将力学参数导入模型，进行有限元分析。结果显示，TBM 组总有效率明显高于对照组。生物力学分析表明，椎体的应力主要分布在 C3/4 棘突；变形主要集中在 C3 椎体的前突。C3~C7 节段椎间盘的应力主要分布在 C3/4 椎间盘的前部分，变形延伸至 C3/4 核髓的后部分。综上所述，这些数据表明 TBM 对 CSR 的治疗有效。有限元模型和生物力学分析的结果为有效避免医源性损伤和提高 TBM 治疗 CSR 患者的效果提供了重要依据。
