Wheelchair users can periodically suffer from skin ulcers or sores caused by friction, pressure, and shear stresses where their skin is constantly in contact with the synthetic materials of their wheelchair. Pressure sores can become a chronic problem, always susceptible to serious infection or additional damage to the skin. New research in the International Journal of Biomedical Engineering and Technology, looks at how a load-distribution approach can be used to customize wheelchairs for their users to avoid such pressure sores.
