Title: Blood Flow and Pressure Changes That Occur With Tilt-in-Space
Author: Sonenblum, Sharon Eve ; Sprigle, Stephen
Abstract: The objective of this study was to evaluate the biomechanical responses to tilt in persons with SCI. Changes in blood flow and loading at the ischial tuberosities (ITs) across different amounts of tilt were measured with Laser Doppler flowmetry and interface pressure. Pressure reduction at the IT was not present at 15°, but did occur with tilts to 30° and greater. Unlike pressure, blood flow increased with all tilts from an upright position. Only 4 of 11 participants had a considerable increase (≥10%) in blood flow at 30° tilt, whereas 9 participants did during maximum tilt (i.e., 45°-60°). Based on the results of this study, tilting for pressure reliefs as far as the seating system permits is recommended to maximize the potential for significant blood flow increases and pressure relief. The use of interim small tilts is also supported, as they also provide some benefit.
