Gait Parameters Analysis in Post-stroke Patients and in Elderly Fallers

A large proportion of falls in older people occurs when walking. Most studies have recently demonstrated correlation between the variations in spatiotemporal gait parameters and fall risk in elderly and in several diseases. The investigators objective is to analyse this parameters in population with gait stability disorders (post-stroke patients and fallers) to identify the most valuable and to develop/test a conglomerate stability score.
