Comparison of normalized skin perfusion in response to wheelchair tilt-in-space (T: 15°, 25°, 35°) in combination with recline (R: 100°, 120°). During tilted and reclined positions, 4 testing positions showed a significant increase in skin perfusion compared with the upright seated position (P<.05), whereas positions at 15° tilt-in-space combined with 100° recline and 25° tilt-in-space combined with 100° recline did not show a significant increase in skin perfusion. Data shown as mean ± SE. Abbreviation: BPU, blood perfusion unit.
