中文摘要 | 本文之主旨在於利用機械運動學的理論,計算出人體腳踝關節軸和下跗關節軸的 位置和方向,人體腳踝關節是由多塊骨頭所構成,就其本身的運動而言是屬於一個多自由度 的機構。 本研究參考有關的文獻,將腳踝關節轉換成一個 R-R 開放迴路機構,再利用剛體 引導理論對此機構作合成而求出轉動軸的位置與方向。在本研究中,首先利用雙平面攝影方 法測量六個人的腳踝,每個人測量五個位置,再把這些位置的座標值利用剛體引導理論,來 算出腳踝關節的位置與方向。由得到的結果,發現人體腳踝關節的運動相當複雜,但站在生 物力學研究者的觀點,可以把它簡化成一個三度空間的 R-R 機構。 本研究所得到的腳踝等 值機構,可以作生物力學上的運動分析和力量分析之用,並可以供作足部義肢設計或鞋類設 計之參考。 |
英文摘要 | The purpose of this study is to apply the theory of kinematics to calculate the positions and directions of the rotation axes of human ankle. Human ankle joint is composed of several bones and is a mechanism of multi-degree of freedom. This study simulates the ankle joint as a R-R open loop mechanism. This R-R mechanism is synthesized by the principle of rigid body guidance. Six peoples' ankles were tested by the technique of bi-plane photography. Five positions were measured each ankle. Putting the coordinate values of all positions into a computer program, the directions and positions of the ankles are obtained. The results show that it is reasonable to regard the human ankle as a three-dimension R-R open loop mechanism. The equivalent ankle joint mechanism developed by this study can be applied for the motion analysis and the force analysis of human ankle. It is also useful to the design of artifical limb and the manufacture of shoes. |
