Deep learning of Parkinson's movement from video, without human-defined measures.

Journal of the neurological sciences Jun 10, 2024
BACKGROUND: The core clinical sign of Parkinson's disease (PD) is bradykinesia, for which a standard test is finger tapping: the clinician observes a person repetitively tap finger and thumb together. That requires an expert eye, a scarce resource, a...
