The long-term goal of this line of research is to develop in-clinic gait metrics that provide ecologically valid assessments of physical function in the real world, for use in both clinical patient care and trial design. The primary goal of the proposed pilot is to test the feasibility of determining relationships between wearable Inertial Measurement Unit (IMU)-acquired gait quality measurements acquired in clinic and in the real world in older adults with varying levels of glaucomatous visual field loss.
