OBJECTIVE
Manual lifting can be burdensome for people who care for power wheelchair users. Although technologies used for dependent transfers are helpful, they have shortcomings of their own. This study compares the usability and task load demand of a novel robot-assisted transfer device to a clinical standard when performing dependent transfers.
DESIGN
A cross-sectional study was conducted to assess caregivers (N = 21) transferring a 56-kg mannequin with the Strong Arm and Hoyer Advance at three transfer locations. Feedback was gathered through qualitative surveys.
RESULTS
Usability was significant in multiple areas important for transfers. Caregiver fatigue and discomfort intensity were reduced, and the Strong Arm was preferred at the three transfer locations. Device ease and efficiency favored Strong Arm at two stations as was discomfort frequency. In addition, physical demand, frustration, and effort were significantly lower using Strong Arm compared with the Hoyer Advance.
CONCLUSIONS
Compared with the Hoyer, participants favored Strong Arm for transfer usability and task load demand. However, further Strong Arm developments are needed.
目的
对于照顾电动轮椅使用者的人来说，手动举升可能会带来负担。虽然用于依赖转移的技术很有帮助，但它们也有自身的缺点。本研究比较了一种新型机器人辅助转移设备与临床标准在进行依赖转移时的易用性和任务负荷需求。
设计
本研究采用横断面研究，评估了 21 名照顾者在三个转移位置使用 Strong Arm 和 Hoyer Advance 转移 56 公斤假人时的表现。通过定性调查收集反馈信息。
结果
在对转移非常重要的多个方面，Strong Arm 具有显著的易用性。照顾者的疲劳和不适强度降低，并且在三个转移位置都更喜欢使用 Strong Arm。在两个位置，Strong Arm 的设备易用性和效率都优于 Hoyer Advance，不适感的发生频率也较低。此外，与 Hoyer Advance 相比，使用 Strong Arm 时，物理需求、挫败感和努力程度显著降低。
结论
与 Hoyer 相比，参与者更喜欢 Strong Arm 进行转移时的易用性和任务负荷需求。然而，还需要进一步开发 Strong Arm。
