Study design: We conducted intradiscal pressure measurements with one volunteer performing various activities normally found in daily life, sports, and spinal therapy. Objectives: 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.

In a letter to the editor of Journal of Nuerosurgery, Dr. Alf Nachemson, whose work on intradiscal pressure is quoted in this study, stated that he believed the test results obtained were invalid on four accounts: • The design did not incorporate a closed system to measure the pressure of the disc, which Intradiscal pressure measurements showed that distraction tension routinely applied by the VAX-D equipment reduced the intradiscal pressure significantly to negative levels in the range of -100 . to -160 mm Hg.

In subsequent years it has become the gold standard for rehabilitation and prevention of low back pain. 1975-08-01 The L5 (last low back) disc has the greatest pressure. In addition, disc pressure changes with changes in bodily positions and activities.

By measurement of intradiscal pressure in vitro, the hydrostatic properties of the nucleus pulposus of normal lumbar intervertebral disc were proven.

Intradiscal pressure measurement was performed by connecting a cannula inserted into the patient's L4-5 disc space to a pressure transducer. The influences of age, sex, disc level, and degree of degeneration on the mechanical behavior of 42 fresh cadaver lumbar motion segments are reported.
