Orthotic prescription for forefoot posting is commonly based upon measures of the forefoot performed on a non-weightbearing foot. However, the relationship of measures of the unloaded foot to determine orthotic prescription for compensatory forefoot function during gait is still in question. Another approach to determine orthotic prescription is to measure the height of forefoot posting necessary to prevent excessive pronation of the subtalar joint during weightbearing. Therefore, the purpose of this study was to determine the intrarater, interrater and day-to-day reliability of forefoot measures during an active, weightbearing movement. Thirty-two volunteers, 18 females (mean age 38.9 +/- 15.3 yr) and 18 males (mean age 44.8 +/- 20.6 yr) participated in the study. Four examiners performed repeated forefoot measures on both feet using the weightbearing technique during two test sessions separated by a week. Intrarater and interrater reliability (ICC (3,1)) ranged from 0.90 to 0.95 and 0.87 to 0.94, respectively. Day-to-day reliability (ICC (1,1)) ranged from 0.84 to 0.88 for all measures. We conclude that the weightbearing method used in this study to determine forefoot posting is reliable. The acceptable reliability of this method justifies the need for future investigations of the validity and the clinical efficacy of this technique for orthotic prescription.
前足垫矫形器的处方通常基于在非负重足部进行的前足测量。然而，非负重足部的测量结果与确定步态中前足代偿功能的矫形器处方之间的关系仍存在疑问。另一种确定矫形器处方的方法是测量在负重过程中防止距下关节过度旋前所需的前足垫高度。因此，本研究的目的是确定在主动负重运动过程中前足测量的测量者内、测量者间以及每日的可靠性。32名志愿者参与了该研究，其中18名女性（平均年龄38.9±15.3岁）和18名男性（平均年龄44.8±20.6岁）。四名检查者在相隔一周的两次测试期间使用负重技术对双脚进行了重复的前足测量。测量者内和测量者间的可靠性（ICC(3,1)）分别为0.90至0.95和0.87至0.94。所有测量的每日可靠性（ICC(1,1)）为0.84至0.88。我们得出结论，本研究中用于确定前足垫的负重方法是可靠的。该方法可接受的可靠性证明了未来对该技术用于矫形器处方的有效性和临床疗效进行研究的必要性。
