I second band work!
I've been in in PT for shoulders, 1 wrist, both knees, right hip, and back. Each time I go in, they always recommend band work not just for rehabbing but also for long term usage. (Some are from accidents, others are from heavy lifting. It eventually takes it toll.) You can really strengthen and build up the muscles, including the ligaments and tendons; especially nice if you have impingement syndrome and/or rotator cuff issues.
Some of the band work I did was as follows:
* Bow and Arrows (Cathe does these in Travel Fit)
* Ys- holding band/tubing in both hands at your side lift your arms up out at a 45 degree angle or so until you come to shoulder height. Once your range of motion improves you can raise it up to as much as head height- but slowly!
* Get down into a push up position, as modified as you need, and instead of pushing up with your arms and chest, do so with your shoulder blades. It's like you are trying to wrap your shoulder blades up and around your spine. Keep your arms straight, but not locked out. As you get stronger you can go from a push up on your knees, to your shins, to a full on plank. *** Even doing this in a seated position only using the weight of your arms helps! it helps to stengthen the Teres Minor/Major and improves posture.
These are the three that I can recommend that don't include over the head motions. I also used a Bow and Arrow type of a "blade" in PT that you shake the heck out of at various angles and motion patterns. Hurts like no other. If you want I can ask my Hubby to get the name of the tool and where to purchase it from when he goes to his next PT visit.
You will probably want to avoid shrugs and up right rows are both cause a lot of neck and upper back/shoulder tension. I've had two PTs say "No more...ever". There are so many small muscles in that area not to mention connective tissues. If your posture is not spot on, and that can be tough as a lot of people have issues with posture in one form or another, it can aggravate muscles and nerves as well as cause injury. Shrugs and upright rows used to be favorites and I'm still tempted every now and then, but pinching a nerve, tweaking something, or having neck tension isn't worth it to me.
A really good stretch:
Lay on the floor with a broomstick or swiffer handle. With your elbows bent and triceps on the floor keeping your elbows tucked into your sides. Your arms are bent at a 90 degree angle with your palms facing you. hold the stick in your hand and slowly move it from side to side holding into the stretch when it feels tight. The key is to not allow your elbows to flare out. You can allow your wrist to touch your body and floor. This was one that my latest PT showed me for my Bursitis/Impingement/Rotator Cuff issues. It can hurt at first when everything is tight, but WOW does it help. It also helps to stretch into the collarbone area, which helps if you are a side sleeper like me.
