Computer simulations of efficacy of air-cell-based cushions in protecting against reoccurrence of pressure ulcers

Ayelet Levy, MSc, et al.

For individuals who depend on a wheelchair for mobility, sitting-acquired pressure ulcers are a common and life-endangering complication. In patients with a spinal cord injury in particular, changes that affect the weight-bearing tissues of the buttocks may increase the risk for pressure ulcers, exposing this already-at-risk population to the additional potential risk caused by soft tissue scarring. Here, we used computational modeling to evaluate the biomechanical efficacies of an air-cell-based cushion for individuals who have previously experienced pressure ulcers that healed but left different types of scars. Our simulations indicate that an air-cell-based cushion is adequately protecting patients with a history of severe pressure ulcers manifested by large, possibly deep tissue scarring in their buttocks.
