• 1)  What is the reason people sway their hips from side to side when they walk?

 

• 2) Since ribs need to be parallel to function efficiently, how do the thoracic vertebrae side-bend without compromising them?

 

• 3)  If the lumbar facets are concave and the thoracic facets convex, how do they mate and how does movement take place?

 

• 4)  What single reason could explain why it has not been possible to correctly align the *sacroiliac joints with manipulation, using existing techniques?

 

• 5)  In lumbar facet physiology, what mechanism causes the joints to side-bend one time and rotate another?

 

• 6)  How do lumbar joints become locked against each other?

 

• 7)  Why are left knee problems common?

 

• 8)  Why is it not physiologically possible to backward bend the thoracic vertebrae and rotate? And what would happen if they could?

 

• 9)  During walking, do the lumbar joints on the weight bearing side, side-bend and rotate to the opposite side or, rotate and side-bend to the same side?

 

• 10)  How many forces acting on a spinal joint take place to lock the joint to the point of changing the chemistry of the local surrounding tissue? 0-1,1-2, 2-3, 3-4, 4-5, 5-6.
