6 months post-op arthroscopic rotator cuff repair problems

[rod physio]

You are progressing as expected. It is good you have nearly full flexion and that amount of external rotation at neutral is good. What is your range at 90 degrees of abduction?

Once you attain good rotator cuff strength you should then expect the ranges to improve further. I generally tell people that full rehab after shoulder surgery is up to 12 months. The reason you get the damage in a shoulder is because the rotator cuff is weak. Surgery makes the rotator cuff weaker so you do start quite far behind the 8 ball. And by the end of the rehab you will probably have better external rotation strength than before the surgery.

I don't know what my range of External Rotation is at 90 degrees of abduction. At my final Physical Therapy session, my pre-treatment Shoulder External Rotation was 36 at neutral and Post-treatment shoulder external rotation was 42 at neutral. I'm working on strengthening my external rotation and rotator cuff muscle by using the red Theraband elastic doing the Resistance shoulder External Rotation uni w/elastic exercise with my arm at side, elbow bent with elastic secured to a secure object at elbow height I will grasp elastic and move my forearm away from the elastic and then return to starting position. I'm also doing the Resistance shoulder abduction(horizontal emphasis) uni w/elastic with elastic attached to a secure object at waist level and arm at side, elbow bent and hand in front of my shoulder I reach out sideways in a straight line and then return to starting position.
How long do you think it will take to attain good rotator cuff strength after I have just started doing these 2 exercises? Of course I will also be doing my other exercises in my home exercise program.

Thanks.
