本篇研究的目的主要是希望能以工地之鷹架為例，探討在平地以及傾斜面上側走時之下肢運動學及壓力中心的改變，同時希望能藉此探討工人在鷹架上行走可能遭受之傷害。共有4位正常的受測者參與此研究。每位受測者依自己覺得最舒適的速度，以右腳為前導腳在平地上側走以及傾斜五度的斜坡上由下往上側走，同時收取運動學及力板的資料加以分析。結果發現壓力中心的軌跡在斜坡側走時較為彎曲，而在平地側走時較為平滑。運動學方面的資料顯示無論在平地或是斜坡側走時，左右腳之腳踝關節的表現有明顯差異。藉由運動學以及壓力中心之軌跡來分析斜坡側走時下肢的生物力學，有助於探討在鷹架上行走之工人可能遭受到之下肢關節的傷害，可以進一步加以預防，減少職業傷害。

Objective: The purposes of this study were to investigate the differences in gait parameters of lower extremity joints and the center of the pressure between level and slope lateral walking, and hopefully to improve labor safety. Method: Four normal subjects participated in this study. The entire lateral walking cycle can be divided into the stance phase and the swing phase. Slope inclinations were set at 5 degree. The subjects walked from the bottom of the slope to the top. The data was collected for 5 seconds for each trial. Results: Similar pattern was found in the first and the second force plate which indicated that the increasing height on the slope didn't change the trajectory of center of pressure. Conclusions: The pattern of the ankle joint of the left foot was significantly different from that of the right ankle during level and slope lateral walking. The results will help labors to decrease the possibility of being injured, and to promote the performance.
