D3.3 Gait Speed App

Principal Investigator: 
Brian Jones, MSEE; Theodore Johnson, MD, MPH
In an earlier TechSAge research project, we investigated options for measuring walking speed as a simple measure to track changes in physical ability, or function. We developed sample tools to help us test if and how health and rehabilitation professionals would measure walking speed in their everyday work. These tools included: an iPhone app (GaitRate), a permanent wall-mount system, and a portable system, all designed for measuring walking speed over a short-distance of around 3 to 5 meters. A 4-meter course length was our target during this research. We tested these tools with various healthcare professionals and learned that the wall-mount device was preferred for clinic and office settings, while an app might better serve visiting physical therapists and nurses in the home setting. As a result of these findings, we polished up the wall-mount system, which was installed in a busy clinic to further understand what challenges arise with everyday use of the device and staff recommendations to promote successful integration (e.g. staff training, reducing interruptions in measurements as to not disprupt workflow).

We are continuing work to commercialize the gait speed app and wall mount system. We have filed for a patent of the wall-mount system and will continue to seek additional funding to test in other clinics. In addition, we are releasing the GaitRate App designed primarily for clinic use to make it available free on Apple AppStore. The website, will provide further information on the status of the app, along with useful resources on gait speed.
