摘要

背景與目的：臨床常用足內側縱弓的塌陷程度來判別功能性扁平足。足印具有直接呈現足底承重形狀及與個案解說之便利性。Ming Scan Foot（MSF）-4足部分析系統具重複使用及電腦輔助分析的優點，能方便臨床工作者操作。本研究用MSF-4足部分析系統來探討：（1）足弓指數與舟狀骨下沉測驗及足部姿勢指數的相關性；（2）足弓指數與狀骨下沉測驗及足部姿勢指數判斷正常足及功能性扁平足的一致性。方法：本實驗收取24名受試者（正常足12位，扁平足12位），進行舟狀骨下沉測驗及足部姿勢指數量測，並使用感壓式足印器（MSF-3 Vers）量測足弓指數。統計分析以皮爾森相關係數及卡帕（kappa）統計進行統計分析。結果：足弓指數與舟狀骨下沉測驗與足部姿勢指數皆達顯著正相關（p ＜ 0.01）。足弓指數與舟狀骨下沉測驗及足部姿勢指數的足型判斷一致性為k score = 0.92（p ＜ 0.01）。結論：本實驗顯示使用MSF足部分析系統測量足弓指數，與舟狀骨下沉測驗及足部姿勢指數有顯著正相關關係及高一致性，可作為臨床上輔助篩檢或輔助診斷的工具。

Background and Purpose: Clinically, it is common to use the degree of collapse of the medial longitudinal arch to determine functional flatfoot. A footprint indicator has the ability to directly display the shape of foot arches and conveniently provide explanations for each case, but the footprint indicator has to use inkpads or expensive optical equipment, which would be difficult to use in clinical practice. The Ming Scan Foot (MSF)-4 foot analysis system has the advantage of repetitive usage and computer assisted analysis, which would be more convenient for clinical workers to operate. This study used the MSF-4 foot analysis system to investigate: (1) correlation between the arch index, Navicular Drop Test, and the Foot Posture Index and (2) whether the foot index of normal and functional flatfoot consistent with the Navicular Drop Test and the Foot Posture Index. Methods: The present study recruited 24 testers (normal foot: 12; flatfoot: 12) to perform and measure the Navicular Drop Test and the Foot Posture Index and used the pressure-sensitive footprint indicator (MSF-3 Vers) to measure the foot arch index. Pearson's correlation coefficient and kappa statistic were used for statistical analysis. Results: Study results showed that the foot arch index and the Navicular Drop Test were positively correlated (p ＜ 0.01). If grouping was performed using the arch index measurement results, there would be a significant consistent with the Navicular Drop Test and the Foot Posture Index (k score= 0.92, p ＜ 0.01). Conclusions: This study used the MSF-foot analysis system to measure the arch index, which was positively correlated and highly consistent with the Navicular Drop Test and the Foot Posture Index. In addition, the system can be used to determine normal foot and flatfoot and as a clinical screening or auxiliary diagnosis tool.
