一项研究发现，与直柄铲相比，弧形手柄铲可减少高达 30% 的背部压力。 Curved-handle shovels reduce back strain by up to 30% compared to straight-handled ones, a study finds.

一项新的研究比较了在爱达荷州冬季除雪的直和曲柄,发现曲柄可以减少高达30%的背部应力,而直柄的模型则能降低30%,尽管两种类型的除雪效率都相似. A new study comparing straight and curved handle shovels for winter snow removal in Idaho finds that curved handle shovels reduce back strain by up to 30% compared to straight-handled models, though both types perform similarly in snow-clearing efficiency. 这项研究由爱达荷大学人体工程学系进行，涉及 50 名参与者在受控的冬季条件下使用每种类型的铲子。 The research, conducted by the University of Idaho’s Department of Ergonomics, involved 50 participants using each shovel type under controlled winter conditions. 结果表明,弯曲的手柄可能有助于防止长期肌肉骨骼伤害,特别是频繁的除雪。 Results suggest that curved handles may help prevent long-term musculoskeletal injuries, especially for frequent snow removal. 目前正在与当地市政当局和硬件零售商分享研究结果,以了解更安全的冬季设备选择。 The findings are being shared with local municipalities and hardware retailers to inform safer winter equipment choices.
