A stadiometer (a device to measure the overall height of a subject) was used to determine the effect of hyperextension in rehydration of the intervertebral disc. Hyperextension for 20 minutes in a prone posture was compared with the prone posture alone for 20 minutes. The stadiometer measurement was made after the subject was exposed to 10 kg of loading applied to the shoulders for five minutes and after each of the recovery postures. It was found that hyperextension gave a significantly increased height recovery compared with the prone posture.
使用身高计（一种测量受试者总体身高的设备）来确定脊柱后伸对椎间盘再水化的影响。将俯卧姿势下脊柱后伸20分钟与单纯俯卧姿势20分钟进行比较。在受试者肩部承受10千克负荷5分钟后以及每种恢复姿势后，使用身高计进行测量。结果发现，与俯卧姿势相比，脊柱后伸后的身高恢复显著增加。
