OCCUPATIONAL APPLICATIONSFalls from ladders remain a significant cause of injuries in workplaces as well as residential settings. While recent research reveals factors related to fall severity from a ladder, strategies that workers can adopt to minimize fall severity are not well understood. Results from our current study indicated that increased upper limb strength, achieving a higher hand hold, and controlled reestablishment of the foot on the rung have summative benefits to reduce fall severity and increase recovery from a misstep perturbation. Ensuring adequate upper limb strength among workers, and training workers to climb ladders leading with hand placement during ascent and foot placement during descent, can facilitate these beneficial strategies to arrest a ladder fall.
职业应用
在工作场所和住宅环境中,从梯子上跌落仍然是受伤的一个重要原因。虽然最近的研究揭示了与从梯子上跌落的严重程度相关的因素,但对于工人可以采取哪些策略来将跌落严重程度降至最低,人们还了解得不够。我们目前的研究结果表明,增强上肢力量、获得更高的抓握高度以及在梯级上控制脚部的重新站稳,对降低跌落严重程度和提高从失足扰动中恢复的能力具有累积益处。确保工人具备足够的上肢力量,并培训工人在攀爬梯子时在上升过程中以手部放置引导、在下降过程中以脚部放置引导,能够促进这些有益策略以阻止从梯子上跌落。
