This study will examine the overall capacity of people with Alzheimer's disease learning fall-resistant skills from perturbation training.
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).

RECRUITINGLab-induced faller rate
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.
Time frame: 6 months
Dynamic stability
Dynamic stability will be calculated for each perturbation trial based on the kinematics of the body's center of mass relative to the base of support.
Time frame: 6 months
Number of prospective fall incident
The number of all cause falls in daily-living activities after the training session will be recorded for each participant.
Time frame: 6 months
