- 生物力学 生物力学
- 职业健康 职业健康 职业健康
背景情况:
- 处理病人的任务对医疗保健工作者来说带来了重大人体工程学风险.
- 在护理人员中,重复应力损伤,特别是在腰部,是很常见的.
- 正在探索诸如外骨之类的技术解决方案,以减轻这些风险.
研究的目的:
- 评估被动背部支外骨架对干部和部生物力学的影响.
- 为了评估外骨对腰部肌肉活动和心率在处理病人期间的影响.
- 为了确定外骨在医疗保健环境中减少肌肉骨应变的潜力.
主要方法:
- 八名参与者执行了四项常见的病人处理任务 (躺到坐,坐到站,站到坐,从床上移到轮椅).
- 干部和部姿势,直立脊柱肌肉活动和心率都与和没有被动外骨架测量.
- 进行了统计分析,以比较条件之间的结果.
主要成果:
- 在坐到站和从床到轮椅的转移任务中观察到勃起脊柱肌肉活动的显著减少 (19%,p < 0.05).
- 峰值双边部曲角度在任务之间减少了多达29°.

Anatomical Positions
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...
