Perception of Affordances and Obstacle Crossing in People With Parkinson's Disease and Healthy Adults

Summary

This study aims to explore how young adults, older adults and people with Parkinson's disease (PwP), perceive their abilty to cross obstacles while walking, and how this perception is related to their actual performance of obstacle crossing and disease-related motor and cognitive impairments. The study will explore this percepeption and the actual performance in different walking environments(floor, synthetic grass turf). Understanding how people perceive obstacles may help improve rehabilitation methods and reduce the risk of falls. The study will take place at the Motor Performance Laboratory, University of Haifa, and will include walking tasks, eye-tracking measurements, and motor and cognitive assessments.
