不同贴扎方式肌内效贴的回缩力特征及其改变皮下间隙的临床研究

Different application pattern of Kinesio taping on altering its retraction force and subcutaneous space of healthy adults

目的:观察不同贴扎方式下肌内效贴的回缩力特征,及贴扎后对健康成人受试者皮下间隙的即刻影响。方法:按测试及干预要求制备肌内效贴(kinesio taping,KT)及具相同颜色、形状及大小的无弹性安慰贴布(placebo taping,PT)。采用济南蓝光XLW型电子拉力机分析施加不同拉力各形状贴布的力学特征。同时选取40例健康成年人,随机配对分为肌内效贴组(KT试验组)与安慰贴扎(PT对照组)各20例。对健康受试者前臂施以不同拉力、回缩方向的Y形贴扎,采用美国通用公司logiq 9型彩超比较贴扎处理前、贴扎后即刻的皮下间隙(subcutaneous space,SS)。结果:1肌内效贴布在施加一定范围的拉力下,回缩力具有等比上升的趋势,但接近极限拉力,会影响其材质的正常特性。贴布长度变长后其整体回缩力反而有所降低。2特定拉力下试验组方法的组内前后比较SS有显著差异(P<0.01),对照组各方法前后比较未见显著差异,与试验组组间比较,SS值也有显著差异(P<0.01)。试验组拉力增加到100%时,SS组内前后比较未见显著性差异。在相同拉力条件下,贴扎方向并没有明显影响SS。结论:肌内效贴材料的回缩力与外在拉力、贴布形状及长度有关。特定的拉力大小下,肌内效贴可影响局部贴扎处的皮下间隙,但力学因素可能大于方向因素。

Objective： To investigate the immediate effect of different application pattern of Kinesio taping（KT） on altering its retraction force and subcutaneous space of healthy adults. Method： KT material were supplied from Nanjing 3H medical corp. Ltd and inelastic placebo taping（PT） with the same color, shape and size were selected. XLW electronic tensile machine were used to analyze different tensile mechanical characteristics of KT with different shape. Forty healthy adults were selected and random- ized into Kinesio taping group （KT experimental group） and placebo group （PT control group）, 1：1 matched with gender, age and BMI. Forearm of healthy subjects were applied Y-shaped taping with different tension and different direction. Subcutaneous space （SS） were evaluated by U.S. GE logiq 9 colour-ultrasound instru- mentore taping and immediately after taping. Result： Under certain range of applied tension, retraction forces of KT increased proportionally. When the tension approach the maximum force, retraction force of KT were corresponded to its＇ shape and area, and the distribution of force was roughly pro- portional; Before and immediately after taping, SS were changed significantly （P〈0.01）, although excess ex- ternal tension might lead to reduced subcutaneous space, but with the same tension, the different taping direc- tion did not show statistically significant influence to SS（P〉 0.05）. Conclusion： Retraction force and external tension of KT are material relevant, and consideration of it＇s shape and length is important for clinical taping. Favorable KT can improve local subcutaneous space and the influ- ence of mechanic may be larer than that of direction.
