Sadly, even a good surgeon is not going to know if there is a functional relationship between the lower back injury and the shoulder. One thing you have to keep in mind about orthos is that they are basically glorified plumbers. They can't diagnose something unless they can see it in a static image. If they can cut into it, then you're right up their alley (and you don't want anyone else touching you in that case), but they generally give LOUSY advice to people with regards to rehab.

Just because they can't see something though doesn't remove that fact that something hurts, and if something hurts then there is obviously something wrong. That is one of the practical applications of getting a MotionDNA assessment. All other tests look at a static image, whereas the MDNA assessment looks at MOVEMENT. By analyzing things like kinematic sequence, and by objectively measuring the speed at every joint it can pin point which segment in the kinetic chain is not doing it's share of the workload.
