In a wheelchair-using population, seating and positioning has a significant impact on pressure injury development. Issues of sensation and mobility deficits, skeletal deformity, muscle tone, spasticity, postural collapse and body habitus all impact pressure, shear and friction. In addition to topical wound treatments, mattress and seating surfaces also contribute therapeutically to pressure injury prevention and healing. This lecture will explore common positional pitfalls as well as the properties of different seating surfaces. This will include a review of immersion and cell deformity that occurs when a person weight bears on a surface. After this lecture, you will be armed with tools that will assist you in quickly assessing postural issues that can prevent and/or mitigate skin injury.
