  • Publication number: 20070108829
    Abstract: In the past, a posterior transfer was only an option using zipper back sling upholstery. The removable swing away solid wheelchair back offers multiple ways to transfer while preventing orthopedic, neuromotor, and respiratory complications from wheelchair positioning. By mounting the swing away removable solid wheelchair back at a slight angle, the rib cage, lungs, and diaphragm are opened making breathing easier when the respiratory system is compromised.
