Developing a Self-Administered Instrumented Motor Exam for Home-based Parkinson’s Disease Assessment Using Wearable Sensors (P3.043)

Objective: To develop a self-administered instrumented motor exam enabling remote measurement of Parkinson’s Disease (PD) signs. Background: Current methods for PD assessment in clinical trials rely on rating scales including the Movement Disorder Society Unified Parkinson’s Disease Rating Scale motor exam (MDS-UPDRS-III). The MDS-UPDRS-III requires in-clinic administration and assessment by neurologists creating significant burden for patients in upcoming disease-modification drug trials, which are likely to benefit from more frequent longitudinal measures. Wearable inertial sensors may be deployed to obtain a lower burden, more precise measurement of standardized exam movements in the home. Design/Methods: Twenty-nine mild to moderate PD patients (Hoehn u0026 Yahr Results: Considering the MDS-UPDRS-III toe tapping task as an example , kinematic features (amplitude and temporal variability), and signal features (spectral entropy), varied significantly with the item-score (p 2 of .59. This approach is currently being applied to the other MDS-UPDRS-III items. Conclusions: We have developed an analytical framework that leverages data from wearable sensors to predict MDS-UPDRS-III item scores. This approach may enable frequent home-based assessments of PD motor function and more precise quantification of medication effects. Study Supported by: The study was supported by Pfizer Inc.
