Eleven piezoelectric pressure transducers, each supporting an area of articular cartilage about 3 mm in diameter, were inserted through the bone of the acetabulum. Nine cadaveric hip joints, thus instrumented, were subjected to forces representing six instants in a typical level walking cycle, including the highest and lowest force. Under the highest force, the maximum pressure measured ranged from 4.93 to 9.57 MN m-2. The transducer positions which were subjected to the highest pressures were subjected at some other instant in the cycle to pressures which were an order of magnitude lower, or to zero pressure.
11个压电压力传感器，每个支撑直径约3毫米的关节软骨区域，通过髋臼骨插入。对9个经过如此仪器安装的尸体髋关节施加代表典型平步行走周期中六个瞬间的力，包括最大力和最小力。在最大力作用下，测得的最大压力范围为4.93至9.57 MN m-2。承受最高压力的传感器位置在周期中的其他某个瞬间承受的压力比最高压力低一个数量级，或者承受零压力。
