VICON系統在步態測量上的應用與評估
Applicaton and Evaluation of the Vicon System in Gait Analysis
摘要
本文利用VICON光學攝影系統，首先取得穿戴固定摩擦式義肢的膝上截肢者下肢肢體在步態擺燙期間，不同肢段角位移、角速度和角加速度等運動參數的資料；再經由電腦對資料的處理與分析，並且配合人體測量參數值的輸入，可以得到肢體運動軌跡變化的情形和下肢步態連桿圖，再來和正常人步態實驗結果做比較分析。結果顯示VICON系統可以在步態測量上提供量化的參考數值，對步態異常的評估及其復健訓練有極大的參考價值。

By employing the VICON system, seg-ment angular displacement, velocity and ac-celeration of the lower limbs were achieved from an Above-Knee (A/K) Amputee using a constant friction prosthesis during the swing phase of the gait cycle. By applying computer for data analysis and inputing anthropometric data of the (A/K) Amputee, kinematic trajectory and a stick diagram of lower limbs were obtained. The data were then compared with those obtained from normal subjects. The results showed that the VICON system can provide quantitative analysis of several important parameters in the gait cycle and that it is very helpful in the evaluation and rehabilitation training of abnormal gait.
