| 摘 要： | 目的 分析中医推拿法作用力各频率段的能量分布，揭示扌衮法的动力学特点。方法 测量6位推拿专家及6位初学者的扌衮法推拿作用力信号，利用小波变换进行频带划分，计算各频率段的能量并进行统计分析。对垂直作用力和水平作用力构造18个特征量，提出了总体评价系数R。结果 专家的扌衮法推拿作用力信号在0~0.406 25 Hz的低频段集中了近70%的能量，另有约20%的能量集中在1.625~3.25 Hz频率段。6位推拿专家总体评价系数R均大于0.70，6位初学者的总体评价系数R均小于0.70，两者具有较显著的差异。结论 扌衮法作用力各频率段的能量分布体现了法“柔和”性及周期性特点。当测试者扌衮法推拿技术动作规范且总体评价系数R大于0.70时，可认为已较好地掌握了扌衮法推拿技术。
