工业上肢外骨架减少了超越头部任务的肩膀肌肉活动. 然而,增加的支持降低了用户的舒适性,这表明需要更好的用户-外骨交互来预防肌肉骨疾病.
科学领域:
- 人体工程学和人类因素
- 生物力学 生物力学
- 职业健康 职业健康 职业健康
背景情况:
- 工业上肢外骨架的目的是通过减少头部任务期间的肌肉负荷来预防肩膀肌肉骨疾病.
- 现有的研究主要集中在外骨架对空头工作的支持上,在更广泛的肩部工作空间中了解它们的有效性方面存在差距.
研究的目的:
- 评估Ottobock Paexo肩部外骨架在广泛的肩部运动中提供的支,从头部到部高度.
- 评估不同的外骨支水平对肌肉活动,上肢动力学以及静态和动态任务中的用户主观反的影响.
主要方法:
- 利用3D运动捕捉和表面电肌图 (EMG) 来记录上肢动力学和肌肉活动.
- 通过关于舒适度和感知支持的问卷收集主观用户反.
- 在使用电动螺丝刀执行任务时,比较了没有外骨,脱离外骨和两级外骨支持 (中等和高) 的性能.
主要成果:
- 外骨支在绑架肩膀姿势中显著降低了体肌肉活动,包括非头部姿势 (-9至-24%).
- 观察到适度的动力学变化 (肩膀曲减少,绑架增加),但动态运动模式没有受到影响.
- 增加外骨支导致了更大的客观效应,但也增加了对变化的主观感知,并降低了感知舒适度.
结论:
- 奥托博克Paexo Shoulder提供了超越传统空头任务的生物机械支持.
- 外骨架辅助水平和用户舒适度之间存在权衡,这表明需要优化人类-外骨架交互.
- 进一步开发是必要的,以加强用户-外骨协同作用,以有效长期预防工业环境中的肌肉骨疾病.
