According to the BBC, it is hard for doctors to be sure of a diagnosis without being able to monitor their speech and movements over a period of time.
But because smartphones have motion detectors, GPS capabilities as well as a microphone, it’s possible to provide additional data for doctors once a patient has left a surgery.
Apparently, changes in people’s voices can be an early symptom of the disease and in a recent study 17,000 individuals provided voice samples over the phone. And motion sensors can be used to measure the way a person moves.
Aston University, in cooperation with the University of Rochester NY are looking for 2,500 people to download the app to their smartphones and perform different tests.
