Three-dimensional scalar pressure distributions were measured in solid tissue near bony prominences in vitro in meat and in vivo in pigs using silicon pressure sensors. Data are in accord with previous theoretical models and indicate that pressure is three to five times higher internally near a bony prominence than it is at the skin over the prominence. Pressure sores are thus thought to begin internally; by the time they are evident at the skin, the sore has worked its way completely from bone to skin. This conclusion is in accord with previous clinical data. Future measurement of local vector forces is needed to fully characterize the force distribution in vivo.
使用硅压力传感器，在体外对肉类中骨突出部位附近的固体组织以及在体内对猪的骨突出部位附近的固体组织进行了三维标量压力分布测量。数据与先前的理论模型一致，表明在骨突出部位内部的压力比突出部位上方皮肤处的压力高3至5倍。因此，人们认为压疮始于内部；当它们在皮肤表面显现时，溃疡已经从骨头完全发展到了皮肤。这一结论与先前的临床数据一致。未来需要测量局部矢量力，以全面表征体内的力分布。
