The purpose of this work was to analyze and compare the movement kinematics of sit-to-stand (STS) and back-to-sit (BTS) transfers between frail aged adults and young subjects, as well as to determine the relationship between kinematic changes and functional capacities.
We analyzed the Timed Up and Go (TUG) movements by using a 3D movement analysis system for real-time balance assessment in frail elderly. Ten frail aged adults (frail group [FG]) and ten young subjects (young group [YG]) performed the TUG. Seven spatiotemporal parameters were extracted and compared between the two groups. Moreover, these parameters were plotted with TUG test duration.
The experiments revealed that there were significant differences between FG and YG in trunk angle during both STS and BTS, and in TUG duration. The trunk angle of the young subjects was more than two times higher than that of the FG. As expected, the TUG duration was higher in the FG than in YG. Trunk angles during both transfers were the most different parameters between the groups. However, the BTS trunk angle and STS ratio were more linked to functional capacities.
There was a relationship between kinematic changes, representing the motor planning strategies, and physical frailty in these aged adults. These changes should be taken into account in clinical practice.
本研究旨在分析和比较体弱老年人与年轻受试者从坐到站（STS）和从站到坐（BTS）转移的运动学特征，并确定运动学变化与功能能力之间的关系。
我们使用三维运动分析系统对体弱老年人进行实时平衡评估，分析定时起立行走（TUG）动作。十名体弱老年人（体弱组[FG]）和十名年轻受试者（年轻组[YG]）进行TUG测试。提取并比较两组的七个时空参数。此外，将这些参数与TUG测试持续时间进行绘图。
实验表明，在STS和BTS过程中，FG组和YG组的躯干角度以及TUG持续时间存在显著差异。年轻受试者的躯干角度比FG组高出两倍多。正如预期的那样，FG组的TUG持续时间高于YG组。两组之间，两次转移过程中的躯干角度是差异最大的参数。然而，BTS躯干角度和STS比率与功能能力的联系更为紧密。
在这些老年人中，代表运动规划策略的运动学变化与身体虚弱之间存在关联。在临床实践中应考虑这些变化。
