摘要

在为期24周的现场环境中,该试验调查了背部支撑外骨骼(BSE)对后勤工人生物力学、工作强度和肌肉骨骼不适的影响。20名工人被随机分为干预组和对照组,分别在有和没有疯牛病的情况下进行日常拣货。在干预期前后的标准化任务中测量了对肌肉活动和运动学的影响,而在整个干预期对工作强度和肌肉骨骼不适进行了评估。结果表明,在24周前后,在BSE辅助下的举重任务中,背部肌肉活动显著减少。虽然有3名疯牛病患者在干预期间停止使用外骨骼,但其余的工人在24周内逐渐增加了他们的日常疯牛病使用,同时感知工作强度总体下降。该试验表明,疯牛病对背部肌肉活动的影响在24周内保持不变,这与之前基于训练研究的假设相反。

Effects of 24-weeks in-field use of a back-supporting exoskeleton on biomechanics, work intensity and musculoskeletal discomfort: A randomized controlled trial among logistic workers
The trial investigated the impact of a back-supporting exoskeleton (BSE) on biomechanics, work intensity, and musculoskeletal discomfort among logistic-workers over 24-weeks in a field-setting. Twenty workers were randomized into intervention and control groups, performing daily order-picking with and without the BSE, respectively. Effects on muscles activity and kinematics were measured during standardized tasks before and after the intervention period, while work intensity and musculoskeletal discomfort were rated throughout the intervention period. The results indicated significant reductions in back muscle activity during lifting tasks with BSE assistance before and after 24-weeks. Although three BSE users stopped using the exoskeleton during the intervention period, the remaining workers progressively increased their daily BSE use associated with an overall decrease in perceived work intensity throughout the 24-weeks. The trial suggests that the effect of the BSE on back muscle activity remains constant over 24-weeks, opposite what was hypothesized based on previous research on training.
