Falls are common and potentially disastrous for older adults. A novel approach that could augment current fall prevention procedures is to teach older adults movement strategies to reduce the risk of injury. The purpose of the study was to determine whether older adults can learn a movement strategy ("tuck-and-roll") that reduces fall impact severity. Learning was quantified with short-term acquisition, bilateral transfer and 1-week-retention. 14 healthy older individuals participated (63.9 ± 5.6 years) in the investigation. Participants were randomly assigned into either training group (n = 7) or active control group (n = 7). All participants performed standardized sideway falls at baseline, immediately post intervention and 1-week-retention tests. During the falling assessments, kinetic and kinematic impact severity parameters were measured. The results for short-term learning revealed that the training group showed greater reduction in hip impact force (33% reduction) than the control group (16% reduction). Furthermore, there was partial bilateral transfer effect and 1-week retention observed in the training group. The observations provide preliminary evidence that teaching tuck-and-roll strategy to older adults has potential effect. The observations provide preliminary evidence that older adults might reduce impact severity utilizing tuck-and-roll strategy during unpredictably-timed sideway falls.
跌倒对于老年人来说很常见,也可能带来灾难性后果。一种新的方法可以增强现有的防跌倒程序,即教导老年人运动策略以降低受伤风险。本研究的目的是确定老年人是否可以学习一种降低跌倒冲击严重程度的运动策略(“抱膝滚动”)。学习效果通过短期习得、双侧转移和一周保持来量化。14 名健康老年人(63.9±5.6 岁)参与了这项研究。参与者被随机分配到训练组(n=7)或主动对照组(n=7)。所有参与者在基线、干预后即刻和一周保持测试时进行标准的侧身跌倒测试。在跌倒评估中,测量了动力学和运动学冲击严重程度参数。短期学习的结果表明,与对照组(16%的减少)相比,训练组的髋部冲击力量减少更多(33%的减少)。此外,训练组还观察到部分双侧转移效应和一周保持。这些观察结果初步表明,向老年人教授抱膝滚动策略可能具有效果。这些观察结果初步表明,老年人在不可预测的侧身跌倒时可能会利用抱膝滚动策略来降低冲击严重程度。
