Very important points.
In 1981, I worked with Richard Dontigny. I read that the SIJ is a shock absorber, so I developed several multidirectional load-spring-recoil tests, the same tests I used on my truck's shock absorber. In 1992, a study used fluoroscopy to apply forces to the joint at multiple angles. Each test showed one thing. They did not show rotations or glides; they showed compression and recoil. I believe they offer a window into the nervous system and help evaluate restrictions or increases in mobility based on the status of multiple muscles that are hard to assess any other way. I abandoned the stork test prior to 1992. Intuitively, it made no sense. We need to do a deep dive on the Laslett cluster, anybody in? The cluster is highly over-interpreted.
