Study and Analysis of Biomechanical Parameters of Human Movement Based on Disability Indicators in Older Adults

Study Overview
=================
Brief Summary
-----------------
Older adults develop modifications in the execution of movement that lead to impairments in activities of daily living performance. Accordingly, there is a need for technological advances in devices that assist older adults targeting improvements in parameters of movement performance that have the highest impact on the skills of daily living. Therefore, to gather the parameters of movement impacting daily living activities, the main goal of this study is to perform a comparative analysis of the biomechanical movement parameters between older adults with and without disability, performing the tasks: gait, sit-to-stand, timed up and go, quiet standing and climb and descend stairs. This work was supported by theFundação para a Ciência e Tecnologia (FCT), [grant number 2020.05356.BD] and through R&D Units funding [UIDB/05210/2020], Fundação para a Ciência e Tecnologia (FCT), Portugal and the European Union.
