基于扰动的平衡训练 (PBT) 可以使用倾斜的平台来模拟,以研究反应性步行. 这种设备有效地诱导后侧跌倒,有助于老年人制定预防跌倒的策略.
科学领域:
- 生物力学 生物力学
- 老年学是指老年学的学科.
- 康复科学 康复科学 康复科学
背景情况:
- 跌倒对老年人构成重大风险,通常导致关节骨折.
- 有效的防摔需要训练个人在跌倒时恢复平衡,特别是在后侧方向.
- 基于扰动的平衡训练 (PBT) 是一种公认的提高反应性步进的方法.
研究的目的:
- 分析一个侧倾的平台所产生的反应性步骤特性.
- 调查平台倾斜度对反应性腿部选择和台阶宽度的影响.
- 评估倾斜平台作为模拟后侧跌倒的工具的潜力,以及其与修改的约束诱导运动疗法 (mCIMT) 的对齐.
主要方法:
- 一项涉及46名健康参与者的横截面研究.
- 参与者在两个角度侧倾的平台上使用"和释放"机动进行了模拟的倒下.
- 使用Kinovea软件分析反应步幅,并进行统计分析,包括ANOVA和费舍尔的精确测试.
主要成果:
- 倾斜的平台引发了缩小的步骤宽度,表明倾向于后侧下降.
- 观察到,没有负载的腿作为反应性腿的明显偏好 (p < 0.001).
- 更高的平台角度显著影响了反应性腿部选择 (p < 0.001).
结论:
- 倾斜的平台有效地模拟了后侧落.
- 观察到的反应性步进特征与修改约束诱导运动疗法 (mCIMT) 中观察到的特征一致.
- 这种设备对开发和评估跌倒预防策略,特别是对于容易跌倒的人来说,非常有前途.
