平面泡沫垫之间的界面压力分布和臀部的坐着的测试对象进行了比较，定制的轮廓垫表面形状产生的一个坐着的Scottck轮廓计。我们的假设是，压力测量可以用来产生一个轮廓等效的力偏转轮廓仪获得。该研究在一所大学医学中心进行，使用脊髓损伤（SCI）（12）和老年人（30）测试对象。使用压力映射垫测量界面压力。使用电子力-偏转轮廓仪测量轮廓形状。压力和轮廓信息减少之前，使用奇异值分解分析。对相应压力和轮廓分解的第一奇异向量中的值进行多项式回归。最好的三次多项式描述的关系，压力和轮廓形状之间的检测表明，界面压力预测最佳轮廓形状。
The interface pressure distributions between flat foam cushions and the buttocks of seated test subjects were compared to custom-contoured cushion surface shapes generated with a seated-buttock contour gauge. Our hypothesis was that pressure measurements could be used to generate a contour equivalent to that obtained with a force-deflection contour gauge. The study was performed in a university medical center using spinal cord injured (SCI) (12) and elderly (30) test subjects. Interface pressure was measured using a pressure mapping pad. Contour shape was measured using an electronic force-deflection contour gauge. Pressure and contour information were reduced prior to analysis using singular value decomposition. Polynomial regressions were performed on the values in the first singular vectors of the corresponding pressure and contour decompositions. Relationships best described by cubic polynomials were detected between pressure and contour shape suggesting that interface pressure predicts optimal contour shape.
