Ninety-one runners were studied to determine whether specific variables were indicative of runners who had suffered with plantar fasciitis either presently or formerly vs runners who had never suffered with plantar fasciitis. Each runner was asked to complete a running history, was subjected to several anatomical measurements, and was asked to run on a treadmill in both a barefoot and shoe condition at a speed of 3.35 mps (8 min mile pace). Factor coefficients were used in a discriminant function analysis which revealed that, when group membership was predicted, 63% of the runners could be correctly assigned to their group. Considering that 76% of the control group was correctly predicted, it was concluded that the predictor variables were able to correctly predict membership of the control group, but not able to correctly predict the presently or formerly injured sufferers of plantar fasciitis.
对91名跑步者进行了研究，以确定特定变量是否能表明目前或以前患有足底筋膜炎的跑步者与从未患过足底筋膜炎的跑步者之间的差异。每位跑步者都被要求填写跑步史，接受多项解剖学测量，并在跑步机上以3.35米/秒的速度（8分钟/英里的配速）进行赤脚和穿鞋状态下的跑步。判别函数分析中使用了因子系数，结果显示，在预测组别归属时，63%的跑步者能够被正确归类到其所属组。鉴于对照组中有76%被正确预测，研究得出结论：预测变量能够正确预测对照组的归属，但无法正确预测目前或以前患有足底筋膜炎的患者。
