Intraosseous pressure (IOP) and cerebrospinal fluid pressure (CSFP) in the lumbar region were measured simultaneously in two groups of patients with either spinal canal stenosis or disc herniation, to compare dynamic changes with positional changes, and to learn whether these pressure changes may have some role in the onset of claudication. IOP and CSFP showed almost the same change patterns with positional changes in two groups. They were lowest in the prone position and highest at the standing position. In standing with flexion, they were almost the same as in the prone position, but in extension they increased above the standing pressure. These dynamic pressure changes could act as a compression force to the cauda equina in the patient with spinal canal stenosis.
在两组分别患有椎管狭窄或椎间盘突出症的患者中，同时测量了腰椎区域的骨内压（IOP）和脑脊液压力（CSFP），以比较其随体位变化的动态变化，并了解这些压力变化是否可能在跛行的发病中起一定作用。两组患者的IOP和CSFP随体位变化呈现几乎相同的变化模式。它们在俯卧位时最低，在站立位时最高。在站立并屈曲时，它们几乎与俯卧位时相同，但在伸展时，它们高于站立压力。这些动态压力变化可能会对椎管狭窄患者的马尾神经起到压迫作用。
