Preventing walking disability in our rapidly aging population is an enormous public health challenge. Fundamental to their loss of functional mobility is that the muscles needed to power walking experience decline in function with age. Wearable assistive devices can be designed to augment the function of these muscles and may make walking easier. If you are a healthy older adult, you may be able to participate in a training intervention to determine the feasibility of a passive wearable ankle device that strengthens walking dynamics and decreases fall risk.

The goal of this interview is to gather a clinician's perspective on the feasibility and potential integration of a new Geriatric Functional Assessment System (GFAS) into their clinical practice. This proposed system is a clinic-based wearable device designed to collect visual and motion data from older adults during their primary care visits that will help assess physical function. Its goal is to collect and process data, apply machine learning, and enable clinicians to identify early signs of functional decline.
