An Objective Assessment Tool for Evaluating Functioning in Older Adults

The Investigators are seeking your consent to participate in research investigating the development of a mobile application that enhances physical and cognitive assessments. This is in response to the growing significance of the Short Physical Performance Battery (SPPB) in Alzheimer's Disease and Related Dementias (AD/ADRD) research. 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. Recognizing the need for accessible and automated assessment tools, this project endeavors to design a mobile app with multi-fold functionality. The final version 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. Our goal is to collect video data from 20 to 30 participants 18+ years of age who are considered healthy with no severe mobility issues to perform the SPPB. The video data will be used to develop a prototype of the SPPB application and validate testing in the lab. The video recording will be automatically encrypted and securely uploaded to Stanford privacy protected computer servers to test and refine the application results.
