摘要

手臂支撑外骨骼（ASE）和背部支撑外骨骼（BSE）可以有效减少各种职业任务中的体力需求，但它们在推拉任务中的效果证据仍然有限。我们研究了使用被动式 ASE 和 BSE 对任务完成时间、肩部和躯干运动学以及推拉中等负荷（100 千克）推车时肩部和背部肌肉活动的影响。40 名志愿者（24 名男性和 16 名女性）完成了这项研究。与无装置（ND）条件相比，使用 BSE 大大减少了男性胸椎和腰椎竖脊肌的活动，尤其是在推车的初始和结束阶段（减少达 31.4%）和拉车的初始和结束阶段（减少达 25.4%）。相比之下，使用 ASE 没有明显的益处，与 ND 相比，女性三角肌前部活动增加（最多增加 46.3%）。这项研究的结果有助于了解 BSE 和 ASE 在推拉任务中的效果，并支持开发更多功能的外骨骼。

Passive arm-support and back-support exoskeletons have distinct phase-dependent effects on physical demands during cart pushing and pulling: An exploratory study

Arm-support exoskeletons (ASEs) and back-support exoskeletons (BSEs) can be effective in reducing physical demands during various occupational tasks, yet evidence of their effects in pushing and pulling tasks remains limited. We examined the effects of using a passive ASE and a BSE on task completion time, shoulder and trunk kinematics, and muscle activity in the shoulder and back while pushing and pulling a moderately loaded (100 kg) cart. Forty volunteers (24 M and 16 F) completed the study. Using the BSE substantially reduced thoracic and lumbar erector spinae muscle activity for males, especially during the initial and ending phases of pushing (by up to ∼31.4 %) and pulling (by up to ∼25.4 %) compared to the No Device (ND) condition. In contrast, using the ASE showed no significant benefits, with females experiencing an increase in anterior deltoid muscle activity (by up to ∼46.3 %) compared to ND. Findings from this study help to understand the effects of BSEs and ASEs in pushing and pulling tasks and support the development of more versatile exoskeletons.
