From: Biomechanical evaluation of a novel wheelchair backrest for elderly people
Results of interface pressure measurements. Comparison of mean total contact area, average pressure, and peak pressure on both the whole backrest and the entire seat across 4 sitting postures, which include relaxed slouching sitting (RSS), flat back support sitting (FBS), prominent lumbar support sitting (PLS), and backward thoracic support sitting (BTS). Error bars indicate SD and *indicates p < 0.05.
