About

The overarching goal is to develop a mHealth App that can use smartphone embedded sensors to objectively collect physical function data in healthy individuals in the context of daily life.

Full description

The goal is to develop a mHealth App using smartphone embedded sensors to objectively collect physical function data in healthy individuals in the context of daily life. The investigators will perform technical development of an internet-interactive App to collect, analyze and transfer the subjects' data. As a proof-of-concept, the mHealth App will execute algorithms that automate deployment of three well-established physical function tests. In a laboratory setting, it will be evaluated usability, acceptability and reliability of the mHealth App compared with traditional performance tests among focus groups. The investigators will then evaluate its usability and acceptability when used in the participants' home environments.
