I had a reverse total shoulder in 2019. Before surgery I called and visited with physical therapists places and decided on one in particular. I was hoping to get the manager physical therapist I talked with but on my first day I got a young man. I totally lucked out, he is awesome. My surgeon had said it’s the hardest joint replacement to get thru that hip is easiest with knee in middle. He told me I had to work hard. Anyhow my therapist 28 at time with his phd and other credentials had rehabbed himself from a torn shoulder muscle surgery, so he knew what I was experiencing to a point. I had him every single therapy visit except one for a year and he said to keep up exercise regimen he provided forever. He used so many things and I still have a regimen of exercises for shoulder daily. He used muscle stimulator, deep tissue massage and dry needling, taping to name a few. I have full range motion. I have theraband pulley I use at home daily 4 min in each direction everyday. Forward side and middle. I do therabands with blue color all different ways exercises using a door and use 5 lb weights. About one month post op I laid down flat on bed and take something like a broom handle starting at chest with both hands and work way over head til I was able to totally go all the way back to bed. It’s a long journey and your not a year yet.
I hope you are still in therapy with same therapist each time. Tell your therapist what issues you are having they are the ones who can help. My therapist has always helped me with my issues until fixed. I still do dry needling on shoulder once month because of an issue surgeon couldn’t fix and it keeps me going. Shoulder is greatly improved compared to pain before surgery
Same physical therapist has seen me thru total knee and has prepared me for hand surgery.
Good luck 🍀 you aren’t a year out yet!
