Shoulder Impingement
Subacromial impingement syndrome
Understanding shoulder impingement
Impingement means the rotator-cuff tendons and the bursa get pinched in the space beneath the tip of the shoulder blade (the acromion), usually when the shoulder-blade and cuff muscles aren't positioning the shoulder quite right as you lift. The good news: it's largely a matter of mechanics, not a structural problem that needs fixing — and it responds very well to retraining how the shoulder moves and strengthening the muscles that make room for the tendons.
The reassuring outlook
Impingement is one of the most treatable shoulder problems with exercise. By strengthening the shoulder-blade muscles and rotator cuff and improving posture, you create more space and better movement — and the pinching settles. Staying gently active and working below the painful arc early is exactly what helps.
What your scans show — and don't
Imaging often reports "bursitis," "tendinosis," or a "spur." These findings are common and frequently seen in pain-free shoulders too — they rarely tell the whole story. How your shoulder blade and cuff move matters far more than the picture, which is why this program focuses on movement and strength.
What you might be feeling
Impingement typically brings a pinch or catch when reaching overhead or out to the side — often a "painful arc" in the middle of the movement — plus ache at night and with reaching behind you. It usually eases as the shoulder-blade mechanics and cuff strength improve. If anything new or unexpected comes up, or you're unsure how you're doing, your care team is the best place to check.
The key: shoulder-blade mechanics + posture
Here's the heart of it: when the shoulder blade glides and tilts properly and your posture is supported, the space under the acromion opens up and the tendons stop getting pinched. So the program leads with shoulder-blade strengthening, posture, and a stretch for the tight back of the shoulder — the things that make room — alongside cuff strengthening.
How this program is built
It starts by calming things and retraining posture and shoulder-blade control, with a gentle stretch for the tight posterior capsule (the back of the shoulder). It then builds cuff and shoulder-blade strength. Early on, favor movements below the painful arc — you'll reclaim the overhead range as the mechanics improve.
Staying comfortable day to day
Keep your posture tall (shoulders back and down), set screens at eye level, and ease up on repetitive overhead reaching while it's irritable. Stretch the back of the shoulder and the chest regularly. Heat before activity and a supportive sleep position can both help.
When it flares
When it's more bothersome: keep moving gently below the painful arc, use heat or ice, ease off overhead reaching for a few days, and a short anti-inflammatory course if appropriate for you. Then ease back in. Flares are part of the rhythm and don't undo your progress.
Tracking how you're doing
Your quick daily check-in gives you and your care team a shared view of how things are trending — a simple way to see progress and keep your care team in the loop. It is not a monitoring or warning system.
