This course 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 impact of posture and a corresponding change in shear stress on interface pressure and internal tissue deformations.
- Participants will be able to define the terms pressure, shear force, shear strain and friction.
- Participants will be able to describe the relationship between interface pressure and tissue deformation.
- Participants will be able to describe 3 ways that slouching impacts tissue loading or deformation.
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.
