Coupled motions of the spine

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 …
