New study on seated buttocks anatomy

sonenblum_study_mri

A new study describes the amount, types, and shapes of tissue present in the buttocks during sitting (i.e., seated buttocks soft tissue anatomy) and the impact of seated buttocks soft tissue anatomy on biomechanical risk. Authored by Sharon Sonenblum, Ph.D., the study is available in the Journal of Tissue Viability here.

Highlights include:

  • Bulk tissue thickness under the seated ischium varied from 5.6 to 32.1 mm.
  • Wheelchair users with a pressure ulcer history have more peaked buttocks contours.
  • Most people do not have gluteus maximus covering their ischial tuberosity.

The ultimate goal of Dr. Sonenblum’s work is to define biomechanical risk of skin breakdown so watch for further study results with data related to risk on various seating surfaces, including the Java Cushion. Ride Designs has supplemented a federal grant awarded to Georgia Tech University to help support this ongoing, important research.
