What Is a Bionic Spine Backrest and How Does It Support Active Wheelchair Users
A bionic spine backrest is best understood as a more structured and anatomical active-wheelchair back-support system, designed to provide greater trunk and spinal support than a simple fabric sling. For active wheelchair users, appropriate back support can contribute to better sitting stability, comfort, shoulder freedom, and propulsion efficiency. Clinical seating guidance also shows that supporting spinal curves and pelvic position can influence posture and functional wheelchair use. However, no backrest is ideal for every user.
