中文摘要 | 二十七位健康的女性,在16種不同的等速膝關節收縮的情況,使用表面 肌電圖記錄其股內側斜肌(VMO)與股外側肌(VL)的肌電活動的比值。此實驗的目 的在於尋找能選擇性促進股內側斜肌的肌電活動的膝彎曲角度似及承重與體關 節內收到肌力比值的影響。本篇研究顯示膝關節彎由的角度與下肢承重與否會影 響股內側斜肌對股外側肌的肌力比值。在膝彎曲60°到90°之間以及承重狀態下 會增加內側斜肌對股外側肌的肌力比值,而髖關節內收則沒有顯著的影響,除了 在承重狀態下。此篇結果建議在彎曲的膝關節與承重的狀態下加上髖關節內收, 股內側斜肌應可被選擇性的加強。(中華物療誌1996;21(2):94-102) |
英文摘要 | Using surface electromyography, the myoelectric activity of the vastus medialis obliques (VMO)and vastus lateratis (VL) were recorded under sixteen different isometric knee extension conditions in 27 healthy female subjects. The purpose of the study was to identify the optimal angle ofknee flexion for selectively facilitating the activity of VMO relative to the VL. Additionally, theinfluence of weight bearing and hip adduction was investigated. It was found that the angle ofknee flexion and weight-bearing had an effect on the ratio of the VMO/VL. At 60° to 90 ° of kneeflexion and weight bearing situation, the ratio of the VMO/VL was greater than other situations.Hip adduction did not have significant influence, except in weight-bearing condition. The resultsof this study suggest that the VMO may be selectively activated on flexed knee in weight-bearingcondition with the assistance of hip adduction. (JPTA ROC 1996;21(2):94-102) |
