Wearable devices are becoming ubiquitous and can be used to better estimate postures and movements to reduce the risk of injuries. Thirty-three participants were recruited in this study to perform two daily repetitive patient transfer tasks while the full body movements were acquired using a set of magneto-inertial wearable devices. The use of wearable devices allowed for the estimation of the forces provoked on the lower back during the entire task performance. In postures where the forces exceeded the warning threshold found in the literature, healthcare workers were considered to have a greater risk of injury. Additionally, the maximum force exerted by each hand to avoid injury to the spinal column was also estimated. Knowing the key anthropometric variables associated with musculoskeletal disorders (MSDs) will enable engineers and researchers to design better assistive devices and injury prevention programs in diverse workplaces.
可穿戴设备正变得无处不在，可以用来更好地估计姿势和动作，以降低受伤风险。在这项研究中，招募了 33 名参与者来执行两项日常重复的患者转移任务，同时使用一套磁惯性可穿戴设备来获取全身运动。可穿戴设备的使用允许估计在整个任务执行过程中对下背部产生的力。在姿势中，如果力超过文献中发现的警告阈值，则认为医护人员受伤的风险更大。此外，还估计了每只手为避免脊柱受伤而施加的最大力。了解与肌肉骨骼疾病（MSD）相关的关键人体测量变量将使工程师和研究人员能够在不同的工作场所设计更好的辅助设备和预防伤害计划。
