The purpose of this investigation was to develop normative ground reaction force data for able-bodied (AB) and trans-tibial amputee (TTA) children during running. Two hundred AB (mean age 9.4 years, range 7-12) and 21 TTA (mean age 11.1 years, range 5-17) children ran (2.2 m/s +/- 10%) over a force platform. Ground reaction force data were normalized, averaged within groups and plotted to produce force-time curves characterizing the different leg types (i.e. able-bodied, non-prosthetic and prosthetic). In addition, discrete variables characterizing the leg type differences were determined. One way ANOVA determined significant differences between variables and a TukeyB Post Hoc analysis defined which variables were significantly different (p < 0.05). Results generally indicated differences between the three leg types with the non-prosthetic leg indicating greater forces than the prosthetic and AB legs. The results of this investigation provide normative ground reaction force data for both AB and TTA children during running and can be used for comparison with other groups of children.
本研究的目的是获取健全儿童（AB）和经胫骨截肢儿童（TTA）在跑步过程中的标准地面反作用力数据。200名健全儿童（平均年龄9.4岁，范围7至12岁）和21名经胫骨截肢儿童（平均年龄11.1岁，范围5至17岁）在测力平台上以（2.2米/秒±10%）的速度跑步。对地面反作用力数据进行标准化处理，在组内求平均值并绘制图表，以生成表征不同腿型（即健全、非假肢和假肢）的力-时间曲线。此外，还确定了表征腿型差异的离散变量。单因素方差分析确定了变量之间的显著差异，TukeyB事后分析确定了哪些变量存在显著差异（p < 0.05）。结果总体上表明三种腿型之间存在差异，非假肢腿所显示的力大于假肢腿和健全儿童的腿。本研究结果提供了健全儿童和经胫骨截肢儿童在跑步过程中的标准地面反作用力数据，可用于与其他儿童群体进行比较。
