An interesting observation was that changes in intradiscal pressure appeared to be minimal until a threshold distraction tension was reached. When the threshold was exceeded the intradiscal pressure was observed to decrease dramatically to levels in excess of 300 mm Hg below the positive pressure observed prior to the application of pelvic tension.

The intradiscal lumbar pressure was measured in 10 patients with para- or tetraplegia and in one normal subject. The pressure was registered both in the horizontal position and during tilting on a table, during the performance of a standardized exercise program for the upper extremities, as well as during cough, during abdominal strain and while the subjects were being turned from the supine to the lateral position. High intradiscal pressures (ten to fifteen kilograms per square centimeter) were found in the normal discs with the subject in the sitting position. In all cases, pressures were highest in the sitting position, about 30 per cent less in the standing position, and about 50 per cent less in the reclining than in the sitting position. 2007-02-14 · In the mid-1950s Alf Nachemson was given an assistant research position under Professor Carl Hirsch at Uppsala University Hospital. To study the loading conditions of the human spine he developed a method for intradiscal pressure measurements.

An orthopaedic challenge (1976年) 外部リンク [編集] 追悼European Spine Journal; Alf Nachemson Memorial Lecture; The Truth About Back Pain The object of this study was to examine the effect of vertebral axial decompression on pressure in the nucleus pulposus of lumbar discs. Intradiscal pressure measurement was performed by connecting a cannula inserted into the patient's L4-5 disc space to a pressure transducer.

Nachemson, A. 1963: The influence of spinal movements on the lumbar intradiscal pressure and on the tensile stresses in the annulus fibrosus. 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.
