Evaluation of a New Seating Concept (IAPRS) for Wheelchair

Intelligent Automatic Pressure Release Seat (IAPRS). The uniqueness of our IAPRS system lies in its ability to prevent sustained and elevated pressure, through dynamic changes in sitting posture. More specifically, the back part of the seat (BPS) periodically tilts inferiorly with respect to the front part of the seat (FPS), while lumbar support is enhanced, thereby unloading the ischial tuberosities, which experience the greatest pressure loads of the seated individual.

Sitting alternately between the Normal (sitting without BPS adjustment) and WO-BPS (sitting with a lowered BPS and enhanced lumbar support) postures, defined as Alternate sitting,

• Significantly reduced interface pressure on the subject's buttocks,
• Promoted tissue perfusion
• Decreased skin temperature elevation
• Maintaining functional performance and comfort for the wheelchair users
• Improved lung capacity

These results confirm that our IAPRS system can have a significant impact in PU prevention for SCI patients.
