Aging and Mixed Perturbation Training
Text
The aim of this project is to investigate the underlying mechanism of perturbation training, the scope of its generalization and retention in real-life fall prevention. In addition, this project explores the possibility of maximizing training effects on both slip and trip fall outcomes among community-dwelling older adults.
