An Objective Assessment Tool for Evaluating Functioning in Older Adults

In response to the growing significance of the Short Physical Performance Battery (SPPB) in Alzheimer's Disease and Related Dementias (AD/ADRD) research, this project aims to create a mobile application that enhances physical and cognitive assessments. The SPPB has proven its value in evaluating lower extremity function and mobility in older adults, providing predictive insights into declines in daily living activities, falls, hospitalization, disability, and mortality. Moreover, recent research has revealed the potential of SPPB in detecting cognitive decline through gait and hand movement analysis at various stages of AD and Mild Cognitive Impairment (MCI). Recognizing the need for accessible and automated assessment tools, this project endeavors to design a mobile app with multi-fold functionality. It will guide users through SPPB tests, offer real-time performance scoring, and facilitate frequent, objective, and accurate physical and cognitive assessments. This is particularly critical for monitoring the progression of ADRD, identifying subtle physical changes indicative of cognitive decline, and enabling timely interventions tailored to patients' evolving needs.
