Standing up from a seated position is a prerequisite for any kind of physical mobility but many older persons have problems with the sit-to-stand (STS) transfer. There are several exosuits available for industrial work, which might be adapted to the needs of older persons to support STS transfers. However, objective measures to quantify and evaluate such systems are needed. The aim of this study was to quantify the possible support of an exosuit during the STS transfer of geriatric patients. Twenty-one geriatric patients with a median age of 82 years (1.-3.Q. 79-84 years) stood up at a normal pace (1) from a chair without using armrests, (2) with using armrests and (3) from a bed with pushing off, each condition with and without wearing an exosuit. Peak angular velocity of the thighs was measured by body-worn sensors. It was higher when standing up with exosuit support from a bed (92.6 (1.-3.Q. 84.3-116.2)°/s versus 79.7 (1.-3.Q. 74.6-98.2)°/s; = 0.014) and from a chair with armrests (92.9 (1.-3.Q. 78.3-113.0)°/s versus 77.8 (1.-3.Q. 59.3-100.7)°/s; = 0.089) compared to no support. There was no effect of the exosuit when standing up from a chair without using armrests. In general, it was possible to quantify the support of the exosuit using sensor-measured peak angular velocity. These results suggest that depending on the STS condition, an exosuit can support older persons during the STS transfer.
从坐姿站起来是任何身体活动的前提，但许多老年人在坐站转移（STS）方面存在问题。有几种适用于工业工作的外骨骼设备，这些设备可以根据老年人的需求进行调整，以支持 STS 转移。然而，需要有客观的措施来量化和评估这些系统。本研究的目的是量化外骨骼在老年患者 STS 转移过程中可能提供的支持。21 名 82 岁中位数年龄（1.-3.Q. 79-84 岁）的老年患者以正常速度（1）从没有使用扶手的椅子上、（2）使用扶手的椅子上和（3）从床上推动起身，每种情况都穿着和不穿着外骨骼。通过佩戴在身上的传感器测量大腿的峰值角速度。当从床上（92.6（1.-3.Q. 84.3-116.2）°/s 与 79.7（1.-3.Q. 74.6-98.2）°/s； = 0.014）和带扶手的椅子（92.9（1.-3.Q. 78.3-113.0）°/s 与 77.8（1.-3.Q. 59.3-100.7）°/s； = 0.089）时穿着外骨骼支持时，站立起来的角速度更高。当从没有使用扶手的椅子上站起来时，外骨骼没有起到支撑作用。总的来说，使用传感器测量的峰值角速度可以对外骨骼的支撑进行量化。这些结果表明，根据 STS 情况，外骨骼可以在 STS 转移过程中为老年人提供支持。
