研究背景與目的:踝關節過度內翻,所造成的扭傷是最常見的運動傷害之一。為了增加踝關節的穩定性,一般相信,可藉由踝關節本體感應運動(ankle proprioceptive exercise)來誘發踝關節控制反射(ankle-controlling reflex),以達到關翻節的保護機制。本研究為探討踝關節的控制反射情形,以及比較有無踝關節本體感應運動者之間,其踝關節的控制反射性差異。方法:本研究共有二十二位自願受測者。該受測者分為兩組。第一組為運動組,其中的受測者均接受了至少六週以上的踝關節本體感應運動;第二組為非運動組,其中的受測者,每週的總運動時間均少於20分鐘。本研究實驗中使用了自行設計的踝關節突然內翻踏板,讓受測者在毫無知會的情形下,使其腳部突然內翻。此時並測量踝關節的內翻角度與腓骨長肌(common peroneal longus)的肌電控制訊號。所有訊號均以1000 Hz同步收集。結果:研究結果顯示,運動組的受試者其踝關節內翻角度較少(16.0±9.8°),而非運動組的受測者其踝關節內翻角度較大(20.0±7.6°)。兩者經t考驗,其結果並無達到顯著差異(p>0.05)。在踝關節突然內翻的動作中,腓長肌的反應時間顯示運動組反應時間(56.5±11.6 msec)明顯地比非運動組反應時間(68.8±9.7 msec)較快。經t考驗其結果達到顯著差異(p<0.05)。結論:本研究結果發現長期的踝關節本體感應運動,是可以改變踝關節的控制反射。依據本研究結果推論,踝關節的本體感應運動是可以增加腓骨長肌內肌梭的敏感度,以及γ神經的活性。經由踝關節的本體感應運動可以促進腓骨長肌肉α-γ神經共同反應,以達到瞬間調節腓骨長肌硬度(stiffness),並達到防止踝關節過份內翻角度所造成的韌帶拉傷。
Purpose: The objective of this study was to investigate the mechanism of ankle protection reflex and to compare the reflexive differences between person with and without receiving ankle proprioceptive exercise training. Method: Twenty-two subjects voluntarily participated in this study. Subjects were categorized into two groups. Group one was the exercise group in which all subjects received at least six weeks of ankle proprioceptive exercise. Group two was the non-exercise group in which all subjects were exercise less than one hour a week. A self-designed foot sudden inversion plate was used. EMG activity of common peroneal longus (CPL) muscle was investigated when the subject sustained an unexpected sudden ankle inversion movement. Ankle motion range and EMG activities were simultaneously collected at a sampling rate of 1000 Hz. Results: The results showed that subjects in exercise group had less ankle inversion angle (16.0±9.8°) than that of subjects in non-exercise group (20.0±7.60). However, this difference did not reach the significant level (p>0.05). The CPL’s reaction time during ankle sudden inversion in the exercise group had significantly shorter reaction time (56.5±11.6 msec) thanthat of the non-exercise group (68.8±9.7 msec). Conclusion: Our results support the theory that ankle protection reflex can be improved through ankle proprioceptive exercise.
