本研究的目的是：(i)设计和制造一种生物力学辅助服装，该服装足够轻且低调，可以穿在衣服里面，或者作为衣服穿，然后（ii）进行人体受试者测试，以评估该服装在倾斜和抬起时减轻腰背肌肉负荷的能力。我们设计了一件原型服装，它与腰伸肌平行作用，以减少腰部肌肉组织承受的力。然后，我们对8名健康受试者进行了测试，让他们在穿着和不穿这种衣服的情况下进行普通的倾斜和抬起任务。我们记录了肌肉活动、身体运动学和辅助力。生物力学辅助服装减轻了腰背部肌肉的负担，在学习任务中平均减少了23-43%的竖脊肌活动，在举重任务中平均减少了14-16%。本研究的实验结果支持使用生物力学辅助服装减少腰背部肌肉负荷的可行性，这可能有助于减少因高强度或重复性力量而导致的损伤风险或疲劳。生物力学辅助服装作为一种轻便、不显眼、经济有效的减轻日常生活中腰背负荷的手段，可能具有广泛的社会吸引力。
The purpose of this study was: (i) to design and fabricate a biomechanically-assistive garment which was sufficiently lightweight and low-profile to be worn underneath, or as, clothing, and then (ii) to perform human subject testing to assess the ability of the garment to offload the low back muscles during leaning and lifting. We designed a prototype garment which acts in parallel with the low back extensor muscles to reduce forces borne by the lumbar musculature. We then tested 8 healthy subjects while they performed common leaning and lifting tasks with and without the garment. We recorded muscle activity, body kinematics, and assistive forces. The biomechanically-assistive garment offloaded the low back muscles, reducing erector spinae muscle activity by an average of 23–43% during leaning tasks, and 14–16% during lifting tasks. Experimental findings in this study support the feasibility of using biomechanically-assistive garments to reduce low back muscle loading, which may help reduce injury risks or fatigue due to high or repetitive forces. Biomechanically-assistive garments may have broad societal appeal as a lightweight, unobtrusive and cost-effective means to mitigate low back loading in daily life.
