This is a preliminary study of the knee forces during the activity of getting out of a chair with and without the aid of arms. The equipment limited the study to the phase of the activity where no contact occurred between the subject and the chair seat. The model of the knee considered was two-dimensional, and quasi-static. Analysis showed that the forces acting in both compartments of the knee were comparable with those occurring during other non-strenuous activities such as level walking. It was also shown that the use of arms to aid rising from a chair causes considerable reduction in both joint and muscle forces.
这是一项关于在有或没有手臂辅助的情况下从椅子上起身活动时膝关节受力的初步研究。该设备将研究限制在受试者与椅座之间没有接触的活动阶段。所考虑的膝关节模型是二维的且为准静态的。分析表明，作用于膝关节两个腔室的力与其他非剧烈活动（如平地行走）期间出现的力相当。研究还表明，使用手臂辅助从椅子上起身会使关节力和肌肉力都大幅降低。
