摘要:目的:通过对踩跷法熟练者与初学者相关力学参数的比较,并结合受试者的主观感受,探讨踩跷法的最佳力学参数范围,为踩跷法的规范化提供依据。方法:运用足底压力测量系统和感压纸测量踩跷法熟练者和初学者的压力分布情况,分析比对所采数据,结合受试者主观感受,分析踩跷临床适宜参数范围。结果:(1)手法熟练者的踩跷力学参数:峰值:201.53±7.80 Kgf;谷值:10.50±1.43 Kgf;波形周期:456.60±2.50 ms;基波频率:2.20Hz±0.01 Hz。手法初学者的踩跷力学参数:峰值:141.60±23.43 Kgf;谷值:5.50±4.72 Kgf;波形周期:374.80±108.51 ms;基波频率:3.00Hz。两者的各参数比较差异均有统计学意义(P<0.01);(2)手法熟练者用力波形峰值及谷值离散度及周期离散度均小于手法初学者;手法熟练者基波频率稳定,干扰小。结论:踩跷力学参数合适的基波频率约为2Hz,在固定时间段内力量保持均匀,力量最大值和最小值基本一致,力量变化周期稳定,其离散度较小。

The determination and comparison of mechanical parameters of Caiqiao manipulation
Abstract: Objective: To explore the best mechanical parameters range for Caiqiao manipulation through the comparison between different parameters from Caiqiao practician or learner and the subjects’ feeling, thus to provide evidence for standardization of Caiqiao manipulation. Method: The instrumental system of feet pressure and pressure responding paper were applied to survey the pressure distribution of Caiqiao manipulation operated by skilled doctor and leaner. The mechanical date and the subjective feeling of receptors were combined to analyze the proper parameters for Caiqiao manipulation. Result: (1) The mechanical parameters of Caiqiao manipulation from skilled doctor are as follows: 201.53±7.80 Kg peak amplitude, 10.50±1.43 Kgf ravine value, 456.60±2.50 ms waveform cycle and 2.2Hz±0.01 Hz fundamental wave frequency. The mechanical parameters of Caiqiao manipulation from learner are as follows: 141.60±23.43 Kgf peak amplitude, 5.50±4.72 Kgf ravine value, 374.80±108.51 ms waveform cycle and 3.00Hz fundamental wave frequency. Compared with parameters of leaner, the differences have statistical significance (P<0.01). (2) The mechanical parameters from skilled doctor such as waveform peak value, ravine straggling degree and periodicity straggling degree were shorter significantly than those of learner’s. The fundamental wave of skilled doctor is more steady with less interference. Conclusion: The suitable wave frequency of Caiqiao manipulation is about 2Hz. During a certain period, the operating strength keeps even. The maximum and minimum value of strength stays equally with steady change period and less straggling degree.
