目的：本研究目的為比較扁平足有足底筋膜炎症狀和無症狀在跑步動作之多肢段足部運動學之差異。方法：本研究以10名受試者為無症狀扁平足組（年齡：21.2±1.03歲、身高：170±8.33公分、體重：70.21±9.14公斤、足弓指數：.37±.02）。10名受試者為足底筋膜炎症狀扁平足組（年齡：25.7±6.49歲、身高：166±8.27公分、體重：69.65±16.95公斤、足弓指數：.35±.02）。受試者以自選速度，跑步動作進行3次，動作過程以8台紅外線高速攝影機和1塊測力板同步收集多肢段足部運動學資料。結果：本研究發現有足底筋膜炎症狀扁平足會顯著減少觸地瞬間前足背曲角度（p=.02），且達到高效果量（Effect size = 1.07）；其餘參數皆沒有達到顯著差異（p>.05）。結論：本研究發現足底筋膜炎症狀扁平足會顯著減少觸地瞬間前足背曲角度，這個結果顯示扁平足罹患足底筋膜炎，其運動學特徵改變主要在前足的矢狀面動作。

Purpose: The purpose of this study was to determine the influence of flat feet with and without plantar fasciitis symptoms on multi-segment foot kinematics during running. Methods: Ten flat feet without plantar fasciitis symptoms (age: 21.2 ± 1.03 years, height: 170 ± 8.33 cm, weight: 70.21 ± 9.14 kg, arch index: .37 ± .02) and ten flat feet with plantar fasciitis symptoms (age: 25.7 ± 6.49 years, height: 166 ± 8.27 cm, weight: 69.65 ± 16.95 kg, arch index: .35 ± .02) participated in this study. The participant performed three running at a self-selected speed. Eight infrared high-speed cameras and one force platform were used to collect multi-foot segment kinematics. Results: The flat feet with plantar fasciitis symptoms demonstrated smaller fore-foot dorsiflexion angle at initial contact than flat feet without plantar fasciitis symptoms (p = .02; Effect size = 1.07). Other variables were not significant (p > .05). Conclusion: This study found decreased fore-foot dorsiflexion angle at initial contact in flat feet with plantar fasciitis symptoms suggesting that flat feet with plantar fasciitis symptoms mainly influenced fore-foot kinematics in sagittal plane.
