Comparison of normalized muscle perfusion in response to wheelchair tilt-in-space (T: 15°, 25°, 35°) in combination with recline (R: 100°, 120°). During tilted and reclined positions, 2 testing positions showed a significant increase in muscle perfusion compared with the upright seated position (P<.05), and the remaining 4 conditions did not show a significant increase in skin perfusion. Data shown as mean ± SE. Abbreviation: BPU, blood perfusion unit.
