The objective of this study was to investigate the pressure applied by superimposed bandages and to compare it with the pressure applied by single-component bandages.
Six different bandages, composed of one elastic bandage, one nonelastic bandage, or both, were applied in a spiral pattern on both legs of 25 patients at risk of venous thrombosis as a consequence of central or peripheral motor deficiency. Pressure was measured at four measurement points on the leg (B1 and C on the medial and lateral sides of the leg) and in three positions: supine, sitting, and standing.
The two single bandages applied similar pressure in the supine position. Their superimposition showed different pressure levels (P < .05) but similar static stiffness index, depending on the order in which the bandage components were applied on the leg. The highest interface pressure was measured at point B1 on the medial side of the leg. This point also showed the highest pressure increase from supine to standing position. The pressure applied by the superimposition of two bandages was computed as a linear combination of the pressure applied by each single component (with a constant term set to 0). However, this linear combination did not properly fit the experimental pressure measurements.
The order of bandage application showed a significant impact on interface pressure. However, the poor correlation between the pressure applied by each bandage component and the pressure resulting from their superimposition underlined the poor understanding of interface pressure generated by the superimposition of compression bandages and should lead to further investigations.
本研究旨在探讨叠加绷带施加的压力，并将其与单一成分绷带施加的压力进行比较。
将 6 种不同的绷带（由一条弹性绷带、一条非弹性绷带或两者组成）以螺旋方式应用于 25 名因中枢或周围运动功能障碍而有静脉血栓形成风险的患者的双腿上。在腿部的四个测量点（腿部内侧和外侧的 B1 和 C）和三个位置（仰卧、坐姿和站立）测量压力。
两种单一绷带在仰卧位施加的压力相似。它们的叠加显示出不同的压力水平（P<.05），但静态刚度指数相似，这取决于绷带组件在腿部上的应用顺序。腿部内侧 B1 点测量到的界面压力最高。该点也显示出从仰卧位到站立位压力增加最高。叠加两层绷带施加的压力被计算为每个单层施加的压力的线性组合（常数项设置为 0）。然而，这种线性组合并不能很好地拟合实验压力测量值。
绷带应用顺序对界面压力有显著影响。然而，各绷带组件施加的压力与它们叠加产生的压力之间的相关性较差，突出了对叠加压缩绷带产生的界面压力的理解不足，应进一步进行研究。
