摘　　要：目的:探讨拨针干预脊柱侧凸支具治疗的临床生物力学原理。方法:根据拨针疗法新的设计思路建立实验力学模型,模拟选择7例脊柱侧凸尸体标本,先采用支具疗法干预测量,再在支具基础上增加拨针疗法干预测量。结果:两种方法实验力学模型能够实现拨针疗法对脊柱侧凸载荷的预测,验证了模型的精确性有效性,脊柱侧凸原始侧凸程度7例均值为(59.70±3.37)°,经支具矫正为(49.57±2.79)°,采用拨针疗法联合支具治疗,矫正为(39.43±1.94)°,后者具有明显优势(P<0.05)。从脊柱侧凸胸腰椎凹侧撑开力V,凸侧压缩力T,支具加拨针比单独使用支具省力45%～46%,旋转力矩M_W和压缩力矩M_V省力达45%～47%,对抗肌肉韧带的张力矩M_T也省52%,差异均有统计学意义(P<0.05)。结论:拨针疗法生物力学实验模型的结果证实,拨针干预支具治疗脊柱侧凸能显著降低Cobb角,提高支具校正效率,有利于提高矫正效果,是一种有效的治疗方式。Objective:To investigate clinical biomechanical principle of brace with stiletto needle therapy for scoliosis.Methods:Based on design ideas of teasing needle therapy,building an experimental mechanical model was built,seven specimens with scoliosis were chosen,and treated by brace therapy and then added to stiletto needle therapy.Results:The two experimental mechanical model methods could predict load of scoliosis by stiletto needle therapy,and was verified accuracy and effectiveness of model.The degree of initial scoliosis of 7 patients was(59.7±3.37)°,improved to(49.57±2.79)°by correction of brace,and(39.43±1.94)°by correction of brace with stiletto needle therapy,had significant differences(P<0.05).Lateral distraction force of thoracolumbar fossa from scoliosis as V,compressive force of scoliosis as T,brace with stiletto needle therapy could save effort for 45%to 46%than that of brace,while running torque Mw and compressive torque Mv could save effort about 45%to 47%,save effort of tension torque MT of muscle and ligament for 52%,and had statistical difference(P<0.05).Conclusion:Experimental biomechanical model of teasing needle therapy confirmed that the therapy could significantly reduce Cobb angle,improve correction efficiency of brace and beneficial for correction effect.It is an effective treatment for scoliosis.
