Wearable Inertial Phenotyping of Freezing of Gait in Parkinson’s Disease: Biomechanical Signatures, Subject-Independent Classification, and Clinical Associations
Freezing of gait (FoG) in Parkinson’s disease is clinically heterogeneous, yet wearable-sensor studies predominantly focus on binary FoG detection. We investigated whether right-ankle inertial signals can characterize clinically meaningful FoG manifestations within a three-stage conditional framework. Accelerometer and...
