概括
上肢外骨架 (ULEs) 可能会增加车风险,并在举重任务中损害前方的稳定性,尽管不会影响滑落风险或大多数步态参数. 安全的ULE实施需要解决这些稳定性问题.
科学领域:
- 职业安全和人体工程学
- 生物力学 生物力学
- 人与机器人的交互
背景情况:
- 上肢外骨架 (ULEs) 越来越多地用于减少身体压力和预防职业环境中的肌肉骨疾病.
- 人们担心ULE对工人的稳定性和跌倒风险的潜在影响.
研究的目的:
- 调查ULE使用对行走性能和在执行任务时的稳定性的影响.
- 为了分析时空步行参数,滑行风险 (RCoF),行驶风险 (MFC) 和稳定性 (MoS),使用和不使用ULE辅助.
主要方法:
- 十五名参与者在两个条件下进行了不同负载 (0-15公斤) 的携带任务:带有和没有ULE.
- 步行分析包括时空参数,所需摩擦系数 (RCoF),最低足距 (MFC) 和稳定边缘 (MoS).
主要成果:
- ULEs并没有显著改变大多数步态参数或滑落风险.
- 在使用ULE时,观察到旅行风险的潜在增加.
- 中侧稳定性没有受到影响,但在使用ULE时,前后稳定性受到损害.
结论:
- 虽然ULE有望减少工作量,但必须考虑它们对步行稳定性的影响,特别是前后稳定性和车风险.
- 需要进一步的研究和设计考虑,以确保ULE在工作场所的安全整合,以减轻跌倒风险.

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
