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 ...

1 de may. de 2017 · In a healthy lumbar disc, in vivo pressures in the nucleus are between 460 and 1330 kPa in the seated position, 500 and 870 kPa in the standing position, and 91 and 539 kPa when lying either prone or supine ( Nachemson and Morris, 1964, Nachemson and Morris, 1963, Sato et al., 1999, Wilke et al., 1999 ).
27 de ago. de 2017 · In computational studies, follower load applied to the lumbar spine could increase intradiscal pressure (IDP), intersegmental rotation and facet joint force [8, 9]. The compressive load on the spine reduces the disc height due to the decrease of the volume of mass gelatinous in nucleus pulposus.
1 de jul. de 2015 · This intradiscal pressure is approximately 0.1–0.24 MPa when lying supine, and increases linearly with loading of the disc 47, 86, 87, 88, up to more than 2.0 MPa 86. The quantity of bound water can vary, which changes the intrinsic intradiscal pressure 89.
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.
