6 de mar. de 2011 · Separate experiments using similarly defined load history regimens were performed to verify these predictions by measuring intradiscal pressure with a fibre optic sensor. We found that the ability for intradiscal pressure generation was load history-dependent and exhibited even greater sensitivity than predicted by analytical models.
1 de dic. de 1999 · The spinal load was highly dependent on the angle of the motion segment in normal discs in vivo. The intradiscal pressure in degenerated discs was significantly reduced compared with that of normal discs. However, further studies on the effect of respiratory movement on intradiscal pressure, the dif …
27 de abr. de 2022 · Therefore, our study aimed to develop an inverse dynamic model of the cervical spine, estimate the differences in disc loads, translations, intradiscal pressure and muscle force/activity in a neutral posture and compare these results with data available in the literature.
1 de ago. de 2008 · Studies of lumbar intradiscal pressure (IDP) in standing and upright sitting have mostly reported higher pressures in sitting. It was assumed clinically that flexion of the lumbar spine in sitting relative to standing, caused higher IDP, disc degeneration or rupture, and low back pain. IDP indicates axial compressive load upon a non-degenerate disc, but provides little or no indication of ...
An appropriate abdominal pressure could effectively reduce the spinal load but loss of the pressure could enhance the load on the lumbar spine in a flexion position of the body while lifting a weight ( Andersson et al., 1976 ). In our study, the coordinate system was created at the center of the intervertebral disc.
21 de mar. de 2021 · Intradiscal pressure (IDP) values without external load application (intrinsic pressure) as a function of the segmental level. ID numbers next to the single data points specify the respective ...
The intervertebral disc has a composite structure consisting of a gelatinous proteoglycan-rich nucleus pulposus surrounded by a collagen-rich anulus fibrosus. The proteoglycan in the nucleus pulposus provides high water content within the nucleus pulposus, and in turn, contributes to sustain large loads applied to the vertebral body.
