The Navicular Arch Index : a Reliable and Valid Footprint Parameter to Evaluate Arch Height
舟狀骨足弓指數：能信實有效評估足弓高度的足印參數
摘要
近年來許多文獻指出足弓高度和運動相關性的傷害有密切的關係。足印分析在臨床上常用來評估足弓高度，具有便宜、簡單、無侵犯性的特色。然而現有的足印參數在評估足弓高度的效度方面結論並不一致。這可能是由於現有的足印參數只有幾何學的概念，缺乏解剖學的考量，因此無法真切地代表足弓高度。 本研究提出一種新的足印參數 － 「舟狀骨足弓指數」，並研究該指數與足弓高度的相關性。「舟狀骨足弓指數」定義為對應於舟狀骨粗隆位置的修正後足印寬度與足寬的比值。由於該指數是以舟狀骨粗隆為測量標的，因此具有解剖學的考量。我們用數位化測量器直接測量70位健康成人（38位男性，32位女性）舟狀骨粗隆下緣的足弓高度，用足印分析計算出「舟狀骨足弓指數」，以簡單線性迴歸來分析「舟狀骨足弓指數」與足弓高度的相關性。研究結果顯示「舟狀骨足弓指數」的測量具有極佳的信度 （intrarater intraclass相關係數為0.95; interrater intraclass相關係數為0.81） 並和足弓高度呈現有意義的相關性（Pearson相關係數為－0.70, p＜0.001）。因此用「舟狀骨足弓指數」來評估足弓高度具有良好的信度與效度，可應用在臨床上評估足弓結構。

Recent studies have shown a close correlation between arch height of the foot and activity-related injuries. In the past, attempts to evaluate arch height from footprint parameters have yielded conflicting results. This could be caused by their failure to take anatomy into consideration in the proposed footprint parameters. This study investigates the relationship between arch height and Navicular Arch Index (NAI) - a new footprint parameter developed by us to incorporate anatomical consideration into footprint measurements. NAI is defined as the ratio of modified footprint width to foot width at the site corresponding to the navicular tuberosity. The arch height of seventy healthy subjects (thirty-eight men and thirty-two women) was measured with a digital caliper and NAI was calculated by footprint landmarks. We found that NAI measurement has an excellent intrarater reliability with an intraclass correlation coefficient (ICC) of 0.95 and a good interrater reliability (ICC = 0.81). A significant correlation (Pearson correlation coefficient, r = –0.70, p＜0.001) was found between NAI and arch height. We concluded that NAI yields reliable and valid first order approximation of arch height, and thus may be clinically used to evaluate arch structure.
