PS8.1: System Requirements for Continuous Seat Pressure Mapping

Even with careful adherence to recommendations, wheelchair users still experience pressure injuries. A personal-use, real-time, smart-phone based pressure mapping system may provide wheelchair users essential compensatory visual feedback to better protect their skin. To assess the utility of such system, it is critical to use a pressure sensing mat with adequate accuracy and repeatability over month-long collection periods. Results of experiments that tested long-term and field-based system performance will be reported in this presentation.


Learning Objectives:

Upon completion of this session, attendees will be able to;



Tamara Vos-Draper, OT, ATP, SMS
Mayo Clinic
Rochester, Minnesota
United States

Tamara Vos-Draper is an Occupational Therapist at Mayo Clinic and PhD candidate in the Rehabilitation Science program at University of Minnesota. At Mayo Clinic, she is the primary seating clinic clinician and clinical lead for assistive technology.  About half of her time is spent conducting research in the area of pressure ulcer prevention. Tamara’s passion for research is driven by her patient’s needs and her desire to find better solutions for them.

Melissa Morrow
