尽管临床医生经常对患者进行静态下肢测量，但迄今为止，很少有研究发表支持他们预测动态后脚运动的能力。考虑到过度的后脚运动与各种下肢损伤有关，静态测量预测动态足部运动的能力可能具有重要意义。因此，本研究的目的是确定静态下肢测量是否可以用来预测步行时后脚运动的大小。通过录像测量了27名平均年龄26.1岁的健康青年受试者的各下肢后足运动。此外，对每个受试者进行了17次静态测量，并进行了双侧记录。多元回归分析的结果表明，唯一能够预测最大后足内旋的变量是“舟骨高度差”（r(2) = .17）。17项测量均未发现预测最大内旋时间。这些结果表明，在没有严重足部畸形的健康个体中，下肢和足部的静态测量不能很好地预测动态后脚运动，如通过最大前旋或最大前旋时间来测量。
Despite the fact that clinicians regularly perform static lower extremity measurements on their patients, to date, little research has been published supporting their ability to predict dynamic rearfoot motion. The abilities of static measurements to predict dynamic foot motion could have important implications considering the fact that excessive rearfoot motion has been associated with various injuries of the lower extremity. The purpose of this study, therefore, was to determine if static lower extremity measurements could he used to predict the magnitude of rearfoot motion during walking. Rearfoot motion of each lower extremity was measured from videotape in 27 healthy young adult subjects with a mean age of 26.1 years. In addition, 17 static measurements were measured and recorded bilaterally for each subject. The results of a multiple regression analysis indicated that the only variable that was able to predict maximum rearfoot pronation was the ''difference in navicular height'' (r(2) = .17). None of the 17 measurements were found to predict time to maximum pronation. These results indicate that static measurements of the lower extremity and foot are poor predictors of dynamic rearfoot motion as measured by maximum pronation or time to maximum pronation in healthy individuals without severe foot deformities.
