Healthcare workers make up one of the occupations in the United States that experience the most musculoskeletal injuries. These injuries are often related to the movement and repositioning of patients. Despite previous injury prevention attempts, injury rates remain at an unsustainable level. The purpose of this proof-of-concept study is to provide preliminary testing of the impact of a lifting intervention on common biomechanical risk factors for injury during high-risk patient movements.; Methods: A before-and-after (quasi-experimental) design was utilized to compare biomechanical risk factors before and after a lifting intervention. Kinematic data were collected using the Xsens motion capture system, while muscle activations were collected with the Delsys Trigno EMG system.
Improvements were noted in the lever arm distance, trunk velocity, and muscle activations during the movements following the intervention; Conclusions: The contextual lifting intervention shows a positive impact on the biomechanical risk factors for musculoskeletal injury among healthcare workers without increasing the biomechanical risk. A larger, prospective study is needed to determine the intervention's ability to reduce injuries among healthcare workers.
医疗工作者是美国职业中肌肉骨骼受伤最多的人群之一。这些损伤通常与搬运和重新安置患者有关。尽管之前进行了预防损伤的尝试，但受伤率仍处于不可持续的水平。本概念验证研究的目的是初步测试一种提升干预措施对高危患者运动中常见损伤生物力学风险因素的影响。
采用前后（准实验）设计，比较提升干预前后的生物力学风险因素。运动捕捉系统 Xsens 用于收集运动学数据，而 Delsys Trigno EMG 系统用于收集肌肉激活情况。
干预后，运动过程中的杠杆臂距离、躯干速度和肌肉激活度均有所改善。
背景提升干预对医疗工作者肌肉骨骼损伤的生物力学风险因素有积极影响，而不会增加生物力学风险。需要进行更大规模的前瞻性研究，以确定该干预措施减少医疗工作者受伤的能力。
