Description
Wrist-worn motion trackers have been trained to spot Parkinson's disease before its classic symptoms, using a huge British dataset. Fabian Kahl and co-authors test whether those models travel. They apply them to German and British groups of people with a sleep disorder that often precedes Parkinson's, plus healthy controls.
The British group looked somewhat like the training data but with weaker group differences and weaker model scores. In the German group the differences vanished and the models did worse still. No two cohorts proved statistically equivalent. The authors suspect the models learned the look of early diagnosed disease in one dataset, not universal early markers. They insist on prospective testing in carefully described groups before any clinic use.
