目的：本研究之目的是利用一個倒 L 型的墊子固定在腳踝護具內裡、並用外部綁帶綁定遠端腓骨頭 做為固定，以及使用這個新式的腳踝護具，針對腳踝曾經扭傷的運動員進行靜態、動態平衡及腳踝 疼痛評估。方法：以 24 名大學業餘運動員 (12 名男性、12 名女性) 作為受測者，測試項目包括靜 態、動態平衡測試及疼痛評估，先使用獨立樣本 t 考驗分析控制組與護具組第一次測試的數據；再 以相依樣本 t 考驗分析護具組介入新式護具穿著之前後兩次的數據的差異。結果：結果發現護具組 在穿著新式護具後在開眼狀態的靜態平衡晃動面積明顯較未穿著時大，但是晃動軌跡並未有明顯改 變；然而在動態平衡的平衡誤差在穿著新式護具後顯著小於未穿著新式護具時，因此也導致整體性 的總動態平衡誤差變少，另外在動態活動時的疼痛指數在有無穿著新式護具之間並無差別。結論： 穿著新式護具可改善腳踝扭傷運動員整體動態平衡的能力，但是對於維持靜態姿勢的平衡並未有明 顯改變，且對於動態活動時的疼痛指數並無改善之效果。

Purpose: The purpose of this study was designed a reverse L pad at inside lining of a novel ankle brace with an outside elastic belt to fibular head fixed and to determine the effect of a novel ankle brace on static and dynamic balance and pain while movements. Methods: Twenty- four amateur collegiate athletes (12 Males and 12 female) were recruited to participate this study and divided into control and brace group. The measured outcomes were static and dynamic balance and pain condition while movements. The independed t test was used to analyze the values of the measured outcomes variables between the control and brace group firstly. Then, the paired-t test was used to analyze the values of the measured outcomes variables between the with-wearing and without wearing for brace group secondly. Results: The results was found that the sway area in open eye condition of the static balance with wearing a novel ankle brace significantly more wide than without wearing brace, but the sway path length have no significantly changed. Also, there were showed the decreased in the dynamic balance error with wearing a novel ankle brace of the brace groups than without wearing brace. The results indicated that the total dynamic balance scores decreased when wearing a novel ankle brace of the brace groups. The pain scale while movements had no significantly difference between wearing or non-wearing a novel brace in brace group. Conclusions: Wearing a novel ankle brace can enhance the dynamic balance for athletes with ankles sprain history. However, it cannot alter the static balance and pain condition while dynamic movements.
