To study the loading conditions of the human spine he developed a method for intradiscal pressure measurements. An interesting observation was that changes in intradiscal pressure appeared to be minimal until a threshold distraction tension was reached.

While several previous in vivo and vitro studies determined the intradiscal pressure of the cervical and lumbar spine, the hydrostatic pressure in thoracic intervertebral discs was solely explored in a single in vivo study (Polga et al., 2004).

In the early 1980s, Nachemson and two colleagues found that during active traction, intradiscal pressure actually rises when the back muscles contract to resist the traction [23]. 301 Moved Permanently. nginx 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). Nachemson's disc pressure chart.
