J Rehabil Res Dev. 2013;50(8):1149–56. http://dx.doi.org/10/1682/JRRD.2012.10.0183 Slideshow Project DOI:10.1682/JRRD.2012.10.0183JSP Aim – Explore effects of foot posture and support stiffness properties on soft tissue deformations using magnetic resonance imaging (MRI). Relevance – Heel ulcers are 2nd most common pressure ulcers. – Despite heel ulcers’ significant morbidity and economic cost, understanding of basic pathophysiology of pressure ulcers is lacking because of limited basic research.

Effects of foot posture and heel padding devices on soft tissue deformations under the heel in supine positions in males : MRI studies. J Rehabil Res Dev. 2013;50(8):1149–56. http://dx.doi.org/10/1682/JRRD.2012.10.0183 Slideshow Project DOI:10.1682/JRRD.2012.10.0183JSP Method Subjects were scanned with and without weight bearing, in neutral external rotation position and 90°to supporting surface and with different heel padding devices. Tissue strains were calculated for: – Skin. – Subcutaneous tissue. – Effective (total) soft tissue.

Heel padding devices: – Significantly reduced extent of deformations in both skin and subcutaneous tissues. – Design features substantially influenced tissue deformations.
