实验分析主要是模拟实际起身与坐下之动作，并纪录受试者身体各关节角度变化。在受试者身上黏贴五个反光球，其黏贴位置为耳朵、肩峰、髋部、膝盖及脚踝，反光球主要的目的用以计算各项人体角度。

We mainly simulated rising from a chair and sitting down on a chair in experimental analysis and recorded the changes in the angle of each joint of subjects. Five reflecting light balls were attached to such body parts as an ear, shoulder peak, hip, knee, and ankle, with the main purpose of measuring each angle of joints.

本研究中的躯干倾角定义为以肩峰点与髋关节所形成的线与垂直线之夹角，小腿屈角为膝关节与踝关节所形成的线与垂直线之夹角，大腿水平角度为髋关节与膝关节所形成的线与水平线之夹角，KH定义为站立时地板至膝腘窝之高度。

In the study, the trunk angle (TA) was defined as the included angle between the vertical line and the line formed from the shoulder peak to the hip joint; the shank angle (SA) was defined as the included angle between the vertical line and the line from the knee joint to the ankle joint; the thigh angle (ThA) was defined as the included angle between the horizontal line and the line formed from the hip joint to the knee joint; and the knee height (KH) was defined as the height from the floor to the popliteal fossa while subjects were standing.

本研究利用数字摄影机记录实际动作时的身体关节角度变化，摄影机架设于距离受试者5m远处，并透过影像处理软件计算各关节角度，受试者采取最自然姿势进行起身与坐下动作。

The digital video which was set up at a distance of 5m from subjects was used to record the changes in angles of joints when subjects stood up or sat down; and it calculated the angle of each joint through image processing software. Subjects completed such movements as rising and sitting at the most natural posture.
