The study investigates how different angles of wheelchair tilt and recline affect blood flow in the skin over the sacrum in people with spinal cord injuries. The goal was to see if these adjustments, which are meant to prevent pressure ulcers, might inadvertently reduce blood flow to the sacrum, another common site for ulcers. The researchers measured skin blood flow at the sacrum and ischial tuberosity while participants sat upright and in various tilted and reclined positions.
Wheelchair tilt-in-space and recline can be used to enhance skin perfusion over the ischial tuberosities without reducing sacral skin perfusion.
Tilt-in-space and recline may not increase interface pressure over the sacrum.
More weight may transfer to the thoracic and lumbar areas, rather than to the sacrum, reducing risk of pressure ulcers.
