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 ...
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.
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.
1 de may. de 2017 · The CEP is bonded weakly to a thin underlying layer of perforated cortical bone, the BEP. Under compressive loading, the pressure of the NP pressing against the CEP and BEP can cause them to bulge into the VB by up to 1 mm (Brinckmann et al., 1983, Holmes et al., 1993).
1 de jul. de 2015 · Biomechanics: from hydrostatic pressure to shear stress. Intradiscal pressure is essential for the maintenance of biomechanical behaviour of the intervertebral disc. Intradiscal pressure tensions annulus fibres, and supports the endplate, and as such is the main determinant of disc height and stiffness in axial compression 45, 46.
11 de abr. de 2016 · During the last few decades, researchers have used a number of techniques to estimate spinal loads by measuring in vivo changes in the intradiscal pressure, body height, or forces and moments transmitted via instrumented vertebral implants.
20 de mar. de 2022 · Disc degeneration could be one of the causes of non-specific LBP, and increased intradiscal pressure (IDP) can potentially induce disc degeneration. The differences in vivo IDP in sitting and standing postures have been studied, but inconsistent results have been reported.
