  1. 27 de ago. de 2017 · The present study demonstrates that physiological loading of body weight plays an important role of stress distribution at IVD in the lumbar spine. It was observed that increasing body weight will increase the pressure at nucleus pulposus and annulus fibrosis at all levels of the IVD.

  2. 20 de mar. de 2022 · The primary objective of this systematic review is to compare the differences in vivo IDP between sitting and standing postures. The secondary objective of this review is to compare effect size estimates between (1) dated and more recent studies and (2) healthy and degenerated intervertebral discs.

  3. 1 de dic. de 2004 · The development of lumbar disc rupture is associated with frequent bending and twisting, 18 fatigue loading, 19 heavy physical work, 20 and a sedentary environment that implies hypomobility, but may also contribute to increased intradiscal pressure in the seated posture. 21 Because many epidemiological studies use self-reported back ...

  4. This study investigates the effect of prolonged dynamic loading on intradiscal pressure, disc height and compressive stiffness, and examines their mutual relationships. Methods: Fifteen caprine lumbar discs with 5 mm of vertebral bone on either side were compressed by 1 Hz sinusoidal load for 4.5 h.

  5. 21 de mar. de 2021 · Intradiscal pressure decreases from the upper cervical spine to the sacrum in all loading conditions, considering the same amount of loading for all segmental levels, while the intrinsic...

  6. 21 de mar. de 2021 · Intradiscal pressure decreases from the upper cervical spine to the sacrum in all loading conditions, considering the same amount of loading for all segmental levels, while the intrinsic pressure exhibits a minimum of the regression curve in the mid-thoracic spine.

  7. 1 de ago. de 2008 · In vivo, progressively higher pressures measured from lying, to standing, to lifting a weight, provide evidence that greater compressive load upon the disc is associated with greater IDP (Nachemson and Elfstrom, 1970, Schultz and Andersson, 1981).
