膝關節三度空間活動度之量測分析

本研究以10名膝關節傷害及12名正常膝關節之男性大學生為受測對象，量測開放式運動鏈與閉鎖式運動鏈兩種不同的運動模式中，膝關節做屈曲及伸展動作時，各軸向的角度關係，來探討兩者膝關節穩定性的差異，並且比較有膝關節傷害與無膝關節傷害之間有無差異。經由實驗結果發現；開放式運動鏈圖形之曲線軌跡較無固定的模式可循。閉鎖式運動鏈圖形之曲線軌跡有固定的模式可循。有膝關節傷害組別的比較，均未達到顯著差異。開放式與閉鎖式運動鏈的比較，僅最大外展角度達顯著差異。各參數間之相關，閉鎖式之最大外展角度與開放式之最大外展角度相關、閉鎖式之最大外展角度與Q角度相關、開放式之最大外展角度與Q角度相關。期望測量所得到的膝關節活動度數值，能作為實際設計膝關節護具的依據，並且能對復健運動型態的選擇有所助益。

This study was designed to determine the 3-dimensional range of motion (ROM) for human knee joint in both open-chain and close-chain lower extremity movements. Ten male college students with knee injury history and twelve without knee injury history were recruited as the subjects. Zebris system was used to measure the 3-D coordinates of the major landmarks related the knee joint. The relationship between flexion-extension angle and adduction angle for open-chain motion is not very stable. The relationship between flexion-extension angle and ad-abduction angle for close-chain motion is very smooth and stable which can be used as the index for designing the knee brace. The comparison between injured and normal knee for the injured subjects shows all parameters have no significant difference. The comparison between open-chain and close-chain motions for 22 subjects shows only the maximum ad-abduction angle has significant difference, all the other parameters have no significant difference. The correlation analysis among all parameters shows that the maximum ad-abduction angle between open-chain and close-chain motions is significantly correlated. The Q-angle is significantly correlated to the maximum ad-abduction angles for both open-chain and close-chain motions. This information could be used as an index to design a more comfortable knee brace for patient and to choose a more effective movement in the injured knee rehabilitation plan.
