Can a watch track Parkinson's? small study puts device to the test

This study tested whether a special watch called the Personal KinetiGraph (PKG) can accurately measure movement problems in people with Parkinson's disease. Researchers compared the watch's readings to standard medical tests and video recordings in 19 volunteers, including both people with Parkinson's and healthy controls. The goal was to see if the watch could help doctors track symptoms like walking difficulty, tremors, and fall risk without needing frequent clinic visits.
