Intradiscal pressure under axial compression Axial compression exhibited a strong decrease in the intradiscal pressure from the upper cervical to the upper lumbar region, from where the pressure remained almost constant towards the sacrum (Fig. 3). The cubic regression curve exhibited a high coefficient of determination (r² = 0.875) and

As the most direct method of estimating spinal loads, intradiscal pressure (IDP) has been extensively studied in intervertebral discs in vivo (Nachemson and Morris, 1964, Sato et al., 1999, Takahashi et al., 2006, Wilke et al., 1999) and in vitro (McNally and Adams, 1992, Nachemson, 1960, Naylor and Smare, 1953, Panjabi et al., 1988) over the past six decades.

Intravital Dynamic Pressure Measurements in Lumbar Discs: A Study of Common Movements, Maneuvers and Exercises Issue 1 of Scandinavian journal of rehabilitation medicine: Supplement, ISSN 0346-8720: Authors: Alf Nachemson, Gösta Elfström: Publisher: Almqvist & Wiksell, 1970: Original from: the University of Michigan: Digitized: Aug 13, 2008

Since that time, there have been few data to corroborate or dispute High intradiscal pressures (ten to fifteen kilograms per square centimeter) were found in the normal discs with the subject in the sitting position.

Alf Nachemson. Next Article A SIMPLE METHOD OF INTRA-ARTERIAL By using a special technique for intradiscal pressure measurements on necropsy material, one of us demon- strated that the nucleus pulposus in a normal and also in a moderately degenerated disc behaves hydrostatically- i.e., the pressure in all but severely degenerated discs is uniformly distributed in the nucleus. 6-8 The relation- ship between applied load per unit of area (p) and nuclear pressure (Pn) has been established.

The L5 (last low back) disc has the greatest pressure. In addition, disc pressure changes with changes in bodily positions and activities. Pioneering Swedish orthopedic specialist and professor Alf Nachemson, MD, PhD, [1931-2006] developed a method to measure intradiscal pressures (3).
