Pressure injuries are a significant problem following spinal cord injury (SCI). High interface pressures while lying on a spine board during emergency transport appear to play a major role in their formation. The aim of the present study was to assess the interface pressures and sensing area between the body and the standard spine board (SSB) and a proof of concept spine board prototype (-5). Twenty-one able-bodied subjects were assessed on each board. Interface pressures and sensing area were recorded every minute over 15 min. The mean peak pressure was higher on the SSB at the head, scapulothoracic (S-T), sacroiliac (S-I), and heels (227.6 mmHg, 148.9 mmHg, 360.3 mmHg, and 179.3 mmHg) compared to -5 (51.9 mmHg, 60.1 mmHg, 66.8 mmHg, and 60.2 mmHg). The peak pressure index (PPI) at the head, S-T and S-I was higher on the SSB (100.2 mmHg, 101.6 mmHg, and 270.6 mmHg) compared to -5 (41.6 mmHg, 51.9 mmHg and 58.7 mmHg). An analysis using pairwise comparisons for repeated measures showed that interface pressures ( < .05) and PPI ( < .001) were reduced at all locations. Modifications of a spine board incorporated in -5 can dramatically reduce interface pressures and reduce pressure injury formation.
压力性损伤是脊髓损伤（SCI）后的一个严重问题。在紧急运输过程中躺在脊柱板上时，高界面压力似乎在其形成中起主要作用。本研究的目的是评估身体与标准脊柱板（SSB）和概念验证脊柱板原型（-5）之间的界面压力和感应区域。每个板上评估了 21 名健康受试者。在 15 分钟内，每一分钟记录一次界面压力和感应区域。SSB 在头部、肩胛胸（S-T）、骶髂（S-I）和脚跟处的平均峰值压力较高（227.6mmHg、148.9mmHg、360.3mmHg 和 179.3mmHg），而-5 则较低（51.9mmHg、60.1mmHg、66.8mmHg 和 60.2mmHg）。SSB 在头部、S-T 和 S-I 处的峰值压力指数（PPI）较高（100.2mmHg、101.6mmHg 和 270.6mmHg），而-5 则较低（41.6mmHg、51.9mmHg 和 58.7mmHg）。使用重复测量的配对比较进行分析表明，所有位置的界面压力（<0.05）和 PPI（<0.001）均降低。-5 中包含的脊柱板的修改可以显著降低界面压力并减少压力性损伤的形成。
