扁平足與正常足後足運動的差異研究
A Study of Rearfoot Motion in Flatfeet and Normal Feet in Different Movements
摘要
由於足部結構的不同，造成扁平足族群的足部功能與正常足有所差異，其中後足運動、足弓指標與足弓角度相關性都是觀察此差異的重要指標。本研究首先收集230位役齡男子，以X光及足印踏板分別量測受試者足弓角度與足弓指標以進行二者之相關性研究。其次，在後足運動部分則召集扁平足(169±3.8cm, 63.6±10.91kg)及正常足(171.6±4.9cm, 62.5±7.4kg)各25名役齡男子，以Peak高速攝影機採每秒120張的速度拍攝其靜態站立、4.8公里／小時行走及9.6公里／小時速度慢跑的後足運動角度，以了解扁平足及正常足弓者在不同運動狀態下後足運動角度的差異。實驗所得資料經單因子變異數分析(α=.05)，獲得以下結果：一、足弓指標與正側位足弓角度有正相關達顯著水準，其相關係數為0.36。二、扁平足在靜態站立、走路及慢跑時，其後足外翻角度及後足運動範圍都顯著大於正常足。三、不論是走路或慢跑，扁平足其後足運動範圍都顯著較正常足大，此現象是否會造成其足部受傷，值得進一步追蹤研究。

The structure and function of the flatfoot are different from those of the normal foot. To identify their differences, the rearfoot motion, the arch index, and the lateral arch angle are important reference points. This study was examines the relationship among these points. A total of 230 service men were measured for their arch indexes and arch angles using an X-ray and a footprint pedal. Another 25 flatfooted (169.9±3.8cm, 63.6±10.9kg) and normal footed men (171.6±4.9cm, 62.5±7.4kg) were measured for their rearfoot angles using a Peak Performance System (120 films/sec) in static standing, walking (4.8km/hr), and jogging (9.6km/hr) conditions. The one-way ANOVA was used to analyze all collected data (α=.05). The results are listed below: 1) There was a positive relationship between the arch index and the arch angle, with the related coefficient at 0.36.2) In static standing, walking and jogging, the pronation angles and the range of motion (ROM) of the flatfoot were significantly larger than those of the normal foot. 3) Both ROMs of the flatfoot subjects in walking and jogging were significantly larger than those of the normal footed subjects. To better understand the relationship between this phenomenon and the injury of the foot, further research is needed.
