This project uses a novel non-pharmacological treatment to improve balance and reduce falls in patients with Alzheimer Disease (AD) using a conceptual framework that combines current vestibular physical therapy (VPT) practice guidelines with the latest motor learning theories for cognitively-impaired patients. The modified VPT protocol for AD patients was developed by experts in VPT and motor learning in AD and will be tested. This pilot study will provide much-needed data about whether VPT can be adapted for patients with AD, and whether VPT shows promise in improving or stabilizing balance, spatial cognition, and gait function in patients with AD.
