与步行相比,巴拐杖等移动设备可以降低肌肉氧和度 (SmO2). 医疗膝盖滑板车和自由手拐杖保持SmO2水平,帮助恢复期间的肌肉健康.
科学领域:
- 生理学 生理学 生理学
- 生物医学工程 生物医学工程
- 整形外科 整形外科 整形外科
背景情况:
- 不使用导致肌肉氧和度 (SmO2) 降低,影响愈合和肌肉健康.
- 在康复期间,移动设备对于行走至关重要.
- 了解不同移动设备对肌肉氧化的影响对于患者护理至关重要.
研究的目的:
- 调查各种移动设备在行走过程中对肌肉氧和 (SmO2) 的影响.
- 为了比较行走期间的SmO2水平与使用医疗膝盖滑板车 (MKS),自由手拐杖 (HFC) 和臂拐杖 (AC) 的情况.
主要方法:
- 38名健康参与者完成了四次10分钟的试验:步行,MKS,HFC和AC.
- 近红外光谱 (NIRS) 传感器测量了巨大的横向 (VL),双腿骨 (BF) 和横向胃角 (LG) 中的SmO2.
主要成果:
- 与行走相比,所有测试的移动设备都显著降低了巨大的侧面体 (VL) 中的SmO2 (大约2%) 减少了10%).
- 与步行相比,手臂拐杖 (AC) 导致两腿肌 (BF) 和侧腹肌 (LG) 的SmO2显著降低.
- 医疗膝盖滑板车 (MKS) 和自由手拐杖 (HFC) 保持了与正常行走相比的BF和LG SmO2水平.
结论:
- 移动设备的使用会改变健康个体的肌肉氧化.
- 臂拐杖 (AC) 在多个肌肉群中对肌肉氧气和产生更明显的负面影响.
- 与AC相比,医疗膝盖滑板车 (MKS) 和无手拐杖 (HFC) 似乎更有利于在行走期间保持肌肉氧化.
