Recently, we have proposed a unified approach, based on the use of a Body Sensor Network (BSN) formed by a few body-worn wireless inertial nodes, for automatic assignment of Unified Parkinsons Disease Rating Scale (UPDRS) scores in the following tasks: Leg Agility (LA), Sit-to-Stand (S2S), and Gait (G). Unlike our previous works and the majority of the works appeared in the literature, where UPDRS...
In this paper, we focus on the characterization of the Leg Agility (LA) task, which contributes to the evaluation of the degree of severity of the Parkinson's Disease (PD) through semiquantitative evaluation scales, such as the Unified Parkinson's Disease Rating Scale (UPDRS). By extracting relevant kinematic variables, such as the angular amplitude and speed of thighs' motion, we analyze, in a comparative...
