站立是一项重要而常见的日常活动。这对于独立是必不可少的，也是走路的先决条件。许多老年人和许多有残疾的人在从坐到站的过渡过程中存在问题。本研究的目的是确定股骨截肢者和健康受试者的站立特征是否有任何不同。五名年轻的股骨截肢者和五名健康受试者参与了这项研究。他们被要求起立。使用Optotrak非接触式光学系统记录身体运动。JR3型六轴机器人手腕传感器记录了座椅上的力矢量和力矩矢量。由两个AMTI测力板记录足底压力。研究发现，经股截肢者的站立速度比健康受试者慢。截肢侧的髋关节、膝关节和踝关节的角度与健侧或健侧不同。健康的足部和假肢的负荷量也有很大差异。结果表明，截肢者的站立能力与健康受试者之间存在差异。这些差异可能是许多老年股骨截肢者站立时面临问题的原因之一。
Standing up is an important and common daily activity. It is essential for independence and a prerequisite for walking. Many elderly and many subjects with impairments have problems with transition from sitting to standing. The aim of the present study was to determine whether there was any difference between the characteristics of standing up in trans-femoral amputees and healthy subjects. Five young trans-femoral amputees and five healthy subjects were included in the study. They were asked to stand up. The body motion was recorded using an Optotrak contactless optical system. The force and moment vectors exerted on the seat were recorded by a JR3 six-axis robot wrist sensor. The force under the feet was recorded by two AMTI force plates. The trans-femoral amputees were found to stand up more slowly than the healthy subjects. The angles of the hip, knee, and ankle joints on the amputated side were different from the angles on the healthy side or in the healthy subjects. There was also a great difference in loading between the healthy and the prosthetic foot. It can be concluded that there are differences in standing up between the trans-femoral amputees and the healthy subjects. These differences may indicate a reason for problems many elderly trans-femoral amputees face when standing up.
