The PREEMPT project aims to develop and validate an activity monitor that patients can wear continuously in the acute care setting and report the following metrics in a real-time format.
Sedentary Time (Time spent lying or sitting)
Upright Time (Time spent standing or walking)
Step Cadence (steps per minute)
Gait Speed (m/s or mi/hr)
number of sit to stand transitions
We completed phase 1 of this project in 2017 with Dr. George Hoke acting as the primary investigator. We received additional funding for phase 2 in June of 2019 with Dr. Chris Moore and Ann Tuzson as the primary investigators.
The sponsor for this project and developer of the device is Barron Associates in Charlottesville, VA, who received a phase 1 and phase 2 SBIR grant from the NINR at the NIH. Results from phase 1 were reported in a poster presentation at the American Physical Therapy Association Combined Sections Meeting in Denver, Colorado, in February 2020.

We are currently developing an improved prototype for phase 2 data collection and will begin validation testing in 10 healthy older adults and 50 hospitalized patients in 2021.
