It was found in early testing that the effectiveness of the iPUPc was reduced for individuals with progressively greater physical impairment. After further assessment, it was determined that with their limited physical abilities, they could not maintian their posture for any signifigant period of time, and as such could not enjoy the full benefit of the iPUPc cushion. Additional supports were designed to provide these wheelchair users with the additional support they need, making the iPUPc system both more comfortable and effective. The Backrest consistsof two additional bladder systems. The Pelvic Stabilizer was added to ensure the lower body remained centered and secure while the user goes about their daily activities. The Trunk Support was added to help the user remain upright during normal use. I: Pelvic stabilizer An air bladder is enclosed in a pre-shaped RUBATEX case for each unit. The pelvic stabilizers are designed with specially shaped bladders and foam. When inflated, they form well curved shape to provide firm stabilization of the pelvis, ensuring the user remains centered. When deflated, they are bendable to allow easy transfer in and out the wheelchair. |

II: Trunk support Since thoracic supports can interfere with user transfers in and out the wheelchair, the trunk supports are designed with specially shaped bladders and foam. When inflated, they provide support to the upper body, preventing it from sliding to the left or right during normal tasks. However, a firm support would prevent the user from intentionally leaning to the sides, and may make transfering in and out of the chair more difficult. The ability of for the user to adjust the firmness of this support, or deflate it completely was added to give the users the flexability to perform daily tasks without the supports getting in the way. When deflated, they are bendable to allow easy transfer in and out the wheelchair. |
