通过目视观察，跑步时的足部着地方式可分为后足着地、中足着地和前足着地。然而，足部着地模式也可以使用着地指数（一种需要测力板数据的测量方法）对范围从 0-100%（极端后足到极端前足）进行分类。当无法获得力数据时，必须使用替代方法来量化冲击模式。本文的目的是使用易于实现的运动学测量来量化足部触地模式的连续性，并将其与触地指数测量进行比较。当二十名受试者跑过嵌入式测力台时，收集了他们的力和运动学数据。确定了后足着地、中足着地、前足着地以及赤足四种跑步条件下的着地指数和足部着地角度。足部着地角度计算为足部在矢状面中相对于地面的角度。结果表明，足部触地角度与触地指数显着相关。线性回归模型表明，在没有力数据的情况下，赤脚和穿鞋的情况下，可以准确估计击球指数。
Footstrike patterns during running can be classified discretely into a rearfoot strike, midfoot strike and forefoot strike by visual observation. However, the footstrike pattern can also be classified on a continuum, ranging from 0–100% (extreme rearfoot to extreme forefoot) using the strike index, a measure requiring force plate data. When force data are not available, an alternative method to quantify the strike pattern must be used. The purpose of this paper was to quantify the continuum of foot strike patterns using an easily attainable kinematic measure, and compare it to the strike index measure. Force and kinematic data from twenty subjects were collected as they ran across an embedded force plate. Strike index and the footstrike angle were identified for the four running conditions of rearfoot strike, midfoot strike and forefoot strike, as well as barefoot. The footstrike angle was calculated as the angle of the foot with respect to the ground in the sagittal plane. Results indicated that the footstrike angle was significantly correlated with strike index. The linear regression model suggested that strike index can be accurately estimated, in both barefoot and shod conditions, in the absence of force data.
