This workshop will help to clarify the language and concepts you need to talk about how the buttocks responds to sitting. I will also present data on the relationship between interface pressure and seated buttocks deformation in able-bodied individuals and wheelchair users at risk for pressure injury development. The relationship between pressure and deformation will also be explored across a variety of commercially available wheelchair cushions. Finally, we will look at the role of anatomy and skeletal morphology in pressure ulcer risk.


Learning Objectives

  1. Participants will be able to define the terms pressure, shear force, shear strain and friction. 
  2. Participants will be able to describe the relationship between interface pressure and tissue deformation.
  3. Participants will be able to identify two aspects of anatomy or skeletal morphology that are associated with pressure ulcer risk.

About the Speaker


Sharon Sonenblum, PhD is a Senior Research Scientist in the School of Mechanical Engineering at Georgia Tech. Dr. Sonenblum has been studying wheelchair seating and mobility for over a decade. Her work focuses on two primary areas: the use of assistive technology in everyday life, and tissue health and pressure injury prevention.  Dr. Sonenblum has investigated how people use their power tilt-in-space wheelchairs, manual wheelchairs, and more recently their power adjustable seat height wheelchairs in their everyday lives. Dr. Sonenblum’s work on tissue health has investigated tissue’s response to loading and weight shifts, and the role of weight shift behaviors in pressure injury development.
