Decubitus ulcers are associated with a burden for the patients and cause enormous costs. One of the reasons for the development of decubitus is prolonged exposure to pressure. The aim of this pilot study was to examine the pressure distribution of healthy individuals either positioned in Positioning in Neutral (LiN) or conventional positioning (CON).
Four healthy participants were positioned in a supine, 30° degree side lying and 90° side lying position both in LiN and CON. A thousand pressure sensors in a mattress enabled a visual presentation of low, medium and high pressure on a screen. This presentation was processed by Photoshop in order to count the pixels representing the total support pressure surface and the pressure intensity.
LiN showed, on average, a smaller surface with measurable pressure compared to CON (46,293 versus 64,090 pixels). The areas of medium pressure were comparable. Mean areas of low and high pressure were both smaller in LiN as compared to CON (low: 8315 versus 22,790 pixels; high: 3744 versus 7277 pixels).
The results of this pilot study indicate that LiN is suitable for pressure sore prophylaxis because LiN showed less support surface and less maximum pressure as compared to CON.
压疮给患者带来负担并造成巨大成本。压疮发生的原因之一是长期受压。本试点研究的目的是检查处于中立位定位（LiN）或传统定位（CON）的健康个体的压力分布情况。
四名健康参与者分别在LiN和CON状态下处于仰卧位、30°侧卧位和90°侧卧位。床垫中的一千个压力传感器可在屏幕上直观呈现低、中、高压情况。此呈现通过Photoshop进行处理，以计算代表总支撑压力表面和压力强度的像素数。
与CON相比，LiN平均显示出可测量压力的面积较小（46,293像素对64,090像素）。中压区域相当。与CON相比，LiN中低压和高压的平均面积均较小（低压：8315像素对22,790像素；高压：3744像素对7277像素）。
本试点研究结果表明，LiN适用于预防压疮，因为与CON相比，LiN显示出支撑表面更小且最大压力更低。
