At the present time, there is no easily performed method of measuring foot shape that can quantitatively differentiate types of feet. We studied 44 feet of individuals with normal appearing asymptomatic feet and flat symptomatic feet to find criteria for measurement of foot shape. We found that measurements of footprints are unreliable. Radiographic methods must include measurements in different positions, or at least specify the position of subtalar rotation to be meaningful, since the height of the arch can change just by rotating the tibia. Traditional measurements of talocalcaneal angles have no precision and are unreproducible.
目前，尚无一种易于实施的测量足部形状的方法能够定量区分不同类型的脚。我们研究了44只外观正常无症状的脚和扁平有症状的脚，以寻找测量足部形状的标准。我们发现脚印测量不可靠。放射学方法必须包括在不同位置的测量，或者至少指定距下关节旋转的位置才有意义，因为仅通过旋转胫骨，足弓高度就可能改变。传统的距跟角测量没有精度且不可重复。
