Walking Along Curved Trajectories. Changes With Age and Parkinson's Disease. Hints to Rehabilitation

We briefly recall the fundamental processes allowing us to change locomotion trajectory and keep walking along a curved path and provide a review of contemporary literature on turning in older adults and people with Parkinson’s Disease (PD). The first part briefly summarizes the way the body exploits the physical laws for producing a curved walking trajectory. Then, the changes in muscle and brain activation underpinning this task, and the...
