Lower limb injuries are a large problem in athletes. However, there is a paucity of knowledge on the relationship between alignment of the medial longitudinal arch (MLA) of the foot and development of such injuries. A reliable and valid test to quantify foot type is needed to be able to investigate the relationship between arch type and injury likelihood. Feiss Line is a valid clinical measure of the MLA. However, no study has investigated the reliability of the test.
The purpose was to describe a modified version of the Feiss Line test and to determine the intra- and inter-tester reliability of this new foot alignment test. To emphasize the purpose of the modified test, the authors have named it The Navicular Position Test.
Intra- and inter-tester reliability were evaluated of The Navicular Position Test with the use of ICC (interclass correlation coefficient) and Bland-Altman limits of agreement on 43 healthy, young, subjects.
Inter-tester mean difference -0.35 degrees [-1.32; 0.62] p = 0.47. Bland-Altman limits of agreement -6.55 to 5.85 degrees, ICC = 0.94. Intra-tester mean difference 0.47 degrees [-0.57; 1.50] p = 0.37. Bland-Altman limits of agreement -6.15 to 7.08 degrees, ICC = 0.91.
The present data support The Navicular Position Test as a reliable test of the navicular bone position during rest and loading measured in a simple test set-up.
The Navicular Position Test was shown to have a high intraday-, intra- and inter-tester reliability. When cut off values to categorize the MLA into planus, rectus, or cavus feet, has been determined and presented, the test could be used in prospective observational studies investigating the role of the arch type on the development of various lower limb injuries.
下肢损伤在运动员中是个大问题。然而，对于足内侧纵弓（MLA）的排列与此类损伤发展之间的关系，我们知之甚少。需要一种可靠且有效的测试来量化足型，以便能够研究足弓类型与受伤可能性之间的关系。费斯线是MLA的一种有效的临床测量方法。然而，尚无研究调查该测试的可靠性。
目的是描述费斯线测试的改良版本，并确定这种新的足部排列测试在测试者内和测试者间的可靠性。为强调改良测试的目的，作者将其命名为舟骨位置测试。
使用组内相关系数（ICC）和布兰德-奥特曼一致性界限，对43名健康的年轻受试者进行舟骨位置测试的测试者内和测试者间可靠性评估。
测试者间平均差异为-0.35度[-1.32；0.62]，p = 0.47。布兰德-奥特曼一致性界限为-6.55至5.85度，ICC = 0.94。测试者内平均差异为0.47度[-0.57；1.50]，p = 0.37。布兰德-奥特曼一致性界限为-6.15至7.08度，ICC = 0.91。
目前的数据支持舟骨位置测试是一种在简单测试设置中测量休息和负重时舟骨位置的可靠测试。
舟骨位置测试显示出较高的日内、测试者内和测试者间可靠性。当确定并给出将MLA分类为扁平足型、直足型或高弓足型的截断值时，该测试可用于前瞻性观察研究，以调查足弓类型在各种下肢损伤发展中的作用。
