科学领域:

  • 生物医学工程 生物医学工程
  • 康复医学 康复医学 康复医学
  • 假肢的使用 假肢的使用

背景情况:

  • 恢复感官和自身感知反是下肢截肢患者面临的重大挑战,尽管假肢技术取得了进展.
  • 针对性肌肉再生 (TMR) 手术可以改善四肢控制,但不能完全解决感官反缺陷.

研究的目的:

  • 评估一种新的振动感应传感反装置,用于患有TMR的LE截肢患者.
  • 评估设备对幻肢疼痛 (PLP),步态和患者整体幸福感的影响.

主要方法:

  • 四名接受初级TMR的男性LE截肢患者 (25-68岁) 参加了这项研究.
  • 在假肢使用期间,使用了带有压力传感器和振动执行器的振动器设备,使用了31天.
  • 评估包括疼痛,功能,心理健康,满意度和步态分析.

主要成果:

  • 四分之三的患者报告说PLP降低,步态改善,设备满意度更高.
  • 一名患者经历了焦虑和抑郁的减少.
  • 一个非常活跃的年轻患者的改善程度较小,这表明个体的变化.

结论:

  • 振动反装置显示了改善TMR LE截肢患者的PLP和步态的潜力.
  • 患者的活动水平和心理因素可能会影响设备的疗效.
  • 未来的研究应该探索个性化干预和长期结果.
