我们开发了一种抬臂工作辅助工具，并评估了其减轻葡萄种植期间工作量影响的能力。该工具包括臀带、手臂支架和连接它们的连接器。这个工具可以在任何高度支撑手臂，同时保持佩戴者的肘部向内。当使用该工具进行浆果减薄时，发现三角肌的最大自愿收缩百分比（%MVC）减少了约30%-80%，而不降低效率。八名工人中有七名报告说，使用该工具使他们的工作更容易。
We developed an arm-raising work assistance tool and evaluated its ability to mitigate the effects of the workload during grape cultivation. The tool comprises a hip belt, arm supports, and connectors linking them. This tool supports the arms when held at any height while keeping the wearer’s elbows pulled in. When performing berry thinning using the tool, the percent maximum voluntary contraction (%MVC) of the deltoid muscle was found to reduce by approximately 30%-80% without reducing the efficiency. Seven out of eight workers reported that using the tool made their work easier.
