WebThe movements of each spinal segment are limited by anatomical structures such as ligaments, intervertebral discs, and facets. Specifically, anatomical structures cause the coupling of motions of the spine, that is, movements occur simultaneously. Flexion, extension, translation, axial rotation, and lateral bending are physiologically coupled. WebJun 25, 2015 · Rotation: Note: There is practically no rotation that occurs at the lumbar spine due to the design of the facet joints in the lumbar region, which only allow up to 2 degrees of rotation (this is a protective mechanism, as too much lumbar rotation would put the spinal cord at high risk of injury). The vast majority of trunk/torso rotation occurs in …

WebA system has been developed capable of calculating three‐dimensional spinal motion based on measurements of a series of computed tomography images that has an accuracy similar to that of current motion analysis methods, but future studies will be necessary to apply this system in vivo. Study Design. A three‐dimensional, noninvasive motion … WebDec 5, 2024 · Lateral flexion is not a significant movement at the atlantooccipital joint, in terms of range of motion. In fact, cadaveric studies limit lateral flexion of the upper cervical spine to approximately 5-8° on either side. Furthermore, lateral flexion in the upper cervical spine is both a coupled movement and a double-joint movement. WebLumbar spine coupled motions.
