简要总结
This study will examine the overall capacity of people with Alzheimer's disease learning fall-resistant skills from perturbation training.
详细描述
Falls can cause injury and death in older adults. Those with Alzheimer's disease are at an even higher fall risk. Our goal is to test if people with mild Alzheimer's disease can learn fall prevention skills from the exposure to large-scale perturbations on a treadmill. Two groups with mild Alzheimer's disease will be enrolled. One group will attend a perturbation training session while the other group receives no training. Groups will then be exposed to perturbations on the ground immediately and three or six months after the training. Over six months after the training, daily-living falls will be tracked for both groups. The falls following the perturbations in the lab and daily-living all-cause falls will be compared between groups to test our specific aims: 1) to test if people with Alzheimer's disease can adapt to large-scale external perturbations and learn fall resistant motor skills; 2) to inspect whether people with Alzheimer's disease can retain motor skills learned in Aim 1; and 3) to determine if people with Alzheimer's disease can generalize fall resistant skills to different contexts (treadmill to overground, inside the lab to outside the lab).

研究组 & 干预措施
Training group
This arm will receive a single-session perturbation training treatment on a treadmill under the protection of a safety harness.
干预措施: Perturbation training (Behavioral)
Control group
This arm will not receive perturbation training but will go through harnessed walking on the same treadmill for the same time as the other group.
干预措施: Perturbation training (Behavioral)
结局指标
主要结局
Lab-induced faller rate
时间窗: 6 months
The outcome of each perturbation trial will be determined as a fall if the peak load cell force exceeds 30% of the body weight. The load cell records the force applied to the human body by the safety harness system after a perturbation. The lab-induced faller rate will be calculated as the ratio of the number of fallers to the number of participants within each group.
次要结局
- Number of prospective fall incident(6 months)
- Dynamic stability(6 months)
