Some of those are good-
But to be honest these are exactly what it says "rehab" meaning if you have an "unhealed" injury or a an injury that requires surgery- almost none of these movements are going to help and most likely most of these movements can and will create more muscle guarding and spasms.

I refuse surgery right now and I am doing great, unfortunately I had to learn over years and years that due to complex nature of the shoulder joint complex and the multitude of injuries that can occur each person must take a very dry investigative and unique approach to regaining health and mobility in the joint if avoiding surgery is your goal.
