Would right side bending in standing be a measure of the left QL's ability to contract (due to eccentric lengthening with gravity), or is the right QL doing most of the work?
Right Quadratus Lumborum would do right lateral flexion, depends on the test you would be testing eccentric, concentric, or isometric contraction of either left or right. But in a simple form, which is what you are asking I think, you would be testing right side. (Spinal muscles are always working together in a form of eccentric and concentric cycle)
QL keeps popping up in clinic so this is awesome. Thanks!
