Sit-to-Walk-Based Early Identification of Fall-Risk Older Adults

Status: Proposed / Pending
Funding agency: National Research Foundation of Korea
Research area: Movement Analysis, Aging, Fall Prevention, Frailty, Wearable IMU Sensors
Role: Principal Investigator / Project Lead

This proposed project aims to develop early identification indices for fall-risk older adults based on precise analysis of the Sit-to-Walk (STW) transition. By integrating laboratory-based motion analysis and wireless IMU sensors, the study seeks to quantify movement quality during the transition from sitting to walking and to identify indicators that complement conventional TUG total completion time.

The project focuses on community-dwelling older adults and examines the relationship between STW movement quality, frailty status, and fall history. Key variables include time to first step, center of mass velocity, movement smoothness, lower-limb loading asymmetry, and center of pressure displacement. The expected outcome is a clinically interpretable and field-applicable assessment framework for early fall-risk screening in super-aged societies.
