Reliability and Validity of Tele-Assessment for Functional Performance in Older vs. Younger Adults

This cross-sectional, comparative study aims to examine the intra-rater reliability, validity, and feasibility of tele-assessment versions of three functional mobility tests-the Timed Up and Go (TUG), 30-second Sit-to-Stand (30sSTS), and Gait Speed Test (GST)-in community-dwelling older adults (≥65 years). To provide a comparative perspective, the same assessments will also be administered to a younger, healthy control group (18-44 years). The study seeks to determine whether tele-assessment can serve as a robust and practical alternative to in-person testing, thereby enhancing accessibility and ensuring high-quality functional evaluation in geriatric populations.
