The objective of the present study was to evaluate the relationship between gait adaptation and slip/fall risk of older adults with cognitive impairments. The study investigated the gait characteristics of six healthy older adults and five older adults with dementia. Participants walked on an instrumented walkway at their preferred walking speeds. After ensuring that the preferred walking speeds were consistent, participants' natural posture and ground reaction forces were measured. The results suggested that participants with dementia walked more cautiously yet demanded more friction at the shoe/floor interface at the time of heel contact, increasing the risk of slip initiation. To reduce the risk of slip-induced falls among older adults with dementia, specific gait training to reduce friction demand requirements by increasing the transfer speed of the whole body mass is suggested.
本研究旨在评估认知障碍老年人步态适应与滑倒/跌倒风险之间的关系。研究调查了 6 名健康老年人和 5 名痴呆症老年人的步态特征。参与者以他们的习惯行走速度在仪器化步道上行走。在确保习惯行走速度一致后，测量参与者的自然姿势和地面反作用力。结果表明，痴呆症患者行走时更加谨慎，但在脚跟接触时要求鞋/地界面提供更多的摩擦力，从而增加了滑倒起始的风险。为了降低痴呆症老年人因滑倒而跌倒的风险，建议进行特定的步态训练，通过增加整个身体质量的转移速度来降低对摩擦力的需求。
