本研究目的在比較踝關節護具在限制高低屈曲角度下，模擬高台著地動作對下肢關節力矩之影響，8名無下肢病史的男性參與者(年齡：20.6 ± 1.4歲，身高：179.1 ± 4.91公分，體重：72.1 ± 8.27公斤)。使用一部Mega Speed 30 Ks高速攝影機(100 Hz)及一台AMTI測力板(1000 Hz)以同步方法擷取高台著地動作。影片及測力板分別以Kwon3D及DASYLab 6.0軟體處理所得運動學及動力學之參數，並將實驗參數使用SPSS for Windows 18.0 套裝軟體以相依樣本 t檢定進行統計分析（α=.05）。結果：一、在運動學方面，發現在限制以高屈曲及低屈曲角度的著地後，穿戴護具於著地重心最低時會限制踝關節背屈，且有達到統計上顯著水準(p< .05)；在緩衝期角位移方面，穿戴護具在高低屈曲限制下皆能達到限制關節屈曲的效果，亦皆達到統計上顯著水準(p< .05)。二、在動力學方面，在垂直作用力方面，在低屈曲條件限制下達顯著差異(p< .05)；峰值產生時間則皆未達顯著差異(p> .05)；緩衝期負荷率雖未達顯著差異(p> .05)，在穿戴護具後皆有增加之趨勢，與垂直作用力之增加趨勢相同。本研究結論在模擬高台著地後，穿著踝關節護具，有將作用力集中在垂直向，所以在高低屈曲條件限制下皆有呈現較大的地面反作用力、負荷率及力矩之趨勢。在本實驗亦發現護具能提供關節保護及限制，除了發現穿戴護具在高低屈曲條件限制下身體重心皆有較高之趨勢，亦會將作用力轉移到其他關節。雖本研究在介入踝關節護具後，僅少數幾項參數有顯著差異性(如：關節角度變化與垂直分力)，亦提供日後研究時仍須謹慎參酌各參數之探討與相關護具介入之使用。

The purpose of this study was to investigate the effects of high and low flexion with ankle brace on lower extremity joint torque during a drop jump landing . Eight healthy males(aged = 20.6 ± 1.4 years, height = 179.1 ± 4.91cm, weight = 72.1 ± 8.27kgf) were participated in this study. A camera Mega Speed 30 Ks(100Hz ) and an AMTI force plate(1000Hz)were used synchronously to collect kinematic and kinetic data during the landing phase. The Kwon3D and DASYLab 6.0 software were used for further analyses of the data. The experimental parameters using SPSS for Windows 18.0 software package for dependent sample t test analysis of the statistical analysis(α=.05).Result：1.In Kinematics,all the participated performed a drop jump landing task and limited hip and knee flexion under two ankle brace conditions (wearing and non-wearing).Landing with the ankle brace has significantly limited ankle dorsiflexion when body center of gravity is the lowest(p< .05).In the angular displacement of the buffer phase,it can significantly limit joint dorsiflexion (p< .05).2.In kinetic, the vertical reaction force in low flexion with ankle brace is significant(p< .05),occur time of vertical reactionforce aren’t significant(p＞.05).Loading rates of wearing ankle brace isn’t significant(p＞.05), but the trend is increase the same with the vertical reaction forec.Conclusion of this study is that regardless two kind of landing tactics (high flexion and low flexion), the trend of vertical reaction force, loading rates and torque is increase.The ankle brace can protect and limit the joints, and the body center is higher with brace.The brace also can help to transfer to other joints.Althoughthis study with brace only some parameters are significant(ex:the change of joints angle and vertical reaction forec), also provided to be seriouslyto explore the parameters in studyand use braces.
