In order to study the role of tissue mechanical properties with MR Elastography (MRE) in the etiology of pressure ulcer related deep tissue injury a MRE actuator was added to a previously proposed MR compatible indentation setup for sustained tibialis anterior (TA) muscle loading in rats. We expect that the use of this novel device will provide new insights in the etiology of pressure ulcer related deep tissue injury.
