摘要
目的:研究中医推拿揉法有力、均匀、柔和、深透核心要素生物力学特征.方法:分别选取推拿初学者与熟练者纳入初学组及熟练组,每组10人,采用手套动态压力分布测量系统收集拇指揉法及掌根揉法各3 min力学参数,分析最大压力、峰值压强、压力时间积分(FTI)、压强时间积分(PTI)等10项参数.结果:熟练组拇指揉法和掌根揉法波峰差值均显著低于初学组(P＜0.01,P＜0.05),拇指揉法除波峰差值外的所有力学参数均显著高于初学组(P＜0.05,P＜0.01),掌根揉法最大压力、平均压力、压力极差、PTI、FTI、频率均显著高于初学组(P＜0.05,P＜0.01).结论:熟练组揉法最大压力、平均压力均大;压力波峰差值小、波形均匀,力量输出稳定、动作变形幅度小;FTI、PTI均大,力的累计效应大体现了中医推拿揉法有力、均匀、柔和、深透核心要素的生物力学特征.
Abstract
Objective:To study the biomechanical characteristics of core elements of traditional Chinese medicine tuina kneading,including strength,uniformity,gentleness,and depth.Methods:Novice and experienced tuina practitioners were selected to join the novice group and experienced group,10 people per group,a glove dynamic pressure distribution measuring system was used to collect mechanical parameters during 3 minutes of thumb kneading and palm base kneading,10 parameters including maximum force,peak pressure,force-time integral(FT1),and pressure-time integral(PTI)were analyzed.Results:The difference in wave peak values of thumb kneading and palm base kneading in experienced group was significantly lower than that in novice group(P＜0.01,P＜0.05),all mechanical parameters except the difference in wave peak values of thumb kneading were significantly higher than novice group(P＜0.05,P＜0.01),the maximum force,average force,force range,PTI,FTI,and frequency of palm base kneading were significantly higher than novice group(P＜0.05,P＜0.01).Conclusion:The maximum force and average force of kneading in experienced group are both large;small difference in force peaks wave,uniform waveform,stable power output and small movement deformation amplitude;FTI&PTI are both large and cumulative effect of force is great reflecting the biomechanical characteristics of core elements of traditional Chinese medicine tuina kneading,including strength,uniformity,gentleness,and depth.
