Q

how is rotation and side-bending coupled in the lumbar spine?

A

it is inconsistent in research

BUT
we know that if you start in a neutral spine, then side-bending and rotation are coupled in the OPPOSITE direction

  2. interbody
    • L rotation

  2. approximation → ipsilateral side
    • posterior with inferior glide
29
Q

during L rotation in T8-T9, which facet will be gapping and which will be approximating?

A
