Ailsa Reston, Jon Nock
This article includes evidence and an exemplary new backrest design to illustrate the benefits of better posture when sitting in a wheelchair for prolonged periods. The author Ailsa Reston qualified as an OT in 1986 and is the co-director of RKS based in Chester. RKS and its independent living showroom provide specialist provision of wheelchairs and seating. This front-line experience has given Ailsa proven knowledge regarding effective wheelchair design and the importance of appropriate lumbar support. In her complete article that can be viewed here, Ailsa introduces the key benefits of sitting in a supportive wheelchair. Through good posture and head, trunk and pelvic alignment, chronic discomfort and pain can be minimized along with the risk of more serious irreversible conditions. Her text progresses onto explaining 'posture' as a definition and the health problems that can result from adopting a poor seated position. Regular or permanent wheelchair users can be prone to a multitude of issues ranging from back pain and fatigue through to Musculoskeletal deformities, Intervertebral Disc Degeneration and reduced Occupational Performance. Ailsa continues to discuss selective evidence that supports the need for wheelchair users to achieve a sustained lorded sitting posture, i.e., a healthy upright posture with natural spinal curvature. Commonly traditional wheelchairs have a vertical backrest that does not promote this position, whereas new designs such as the Strong Back include an arched configuration to encourage an extended posture. The most effective angle, position, shape and material employed within a wheelchair backrest is outlined by Ailsa and supported by comments from the Swiss Strong Back inventors. With backrest ergonomics optimized, wheelchair users can avoid many long-term health problems and enjoy a better quality of life.
