Early efforts of measurement of disc pressure began in the 1960s. Nachemson and Morris were the first to assess intradiscal pressure. 3 In 1965, Nachemson observed that the pressure in the AF and NP were different and that disc degeneration could alter the pressure.

Intradiscal pressure (IDP) is the hydrostatic pressure measured in the nucleus pulposus of a non-degenerate intervertebral disc. Standing and sitting are everyday activities, which has made the findings of posture and lumbar IDP studies immediately relevant and memorable. Much lower IDP has been reported in standing than in sitting.

By measurement of intradiscal pressure in vitro, the hydrostatic properties of the nucleus pulposus of normal lumbar intervertebral disc were proven. The hydrodynamic properties seem to exist also in the somewhat degenerated disc, but not in the more severely deranged ones. Intravitally-performed measurements of disc pressure over the Objective: The goal of this study was to measure intradiscal pressure to complement earlier data from Nachemson with dynamic and long-term measurements over a broad range of activities.
