About scapular dyskinesis
The shoulder blade, or scapula, is the moving base for the arm. It needs to rotate and glide smoothly as you reach and lift. In scapular dyskinesis, the blade tips, wings out, or lags behind the arm, which changes the angles inside the shoulder joint.
This altered movement is often a contributor to other problems, such as impingement, rotator cuff pain, and labral irritation. Occasionally, a nerve injury weakens a key shoulder blade muscle and causes visible winging, which needs a different workup.
Common symptoms
- Shoulder pain with reaching, lifting, or throwing
- A shoulder blade that sticks out or looks uneven compared with the other side
- Fatigue or aching around the shoulder blade
- Clicking or snapping near the shoulder blade
- Reduced power or accuracy in overhead sports
Common causes and risk factors
- Weakness or fatigue of the muscles that control the shoulder blade
- Tightness in the chest muscles or back of the shoulder
- Posture and repetitive work or sport patterns
- Injury to the nerves supplying the shoulder blade muscles
- Pain elsewhere in the shoulder that changes how you move
How we diagnose it
Dr. Chen watches the shoulder blades from behind while you raise and lower your arms, and checks strength, flexibility, and the neck. Ultrasound at the exam table looks for rotator cuff or bursa problems that may be driving or following the altered motion. When winging suggests a nerve problem, nerve testing with EMG may be recommended. Sometimes, scapular dyskinesis may be caused by subtle pinched nerves, and ultrasound along with guided nerve blocks may be recommended for assessment.
How Propel treats scapular dyskinesis
Treatment starts with an accurate diagnosis. Treatable causes, such as a pinched nerve, rotator cuff issues, bursa problems, or other nerve issues, are diagnosed and treated accordingly. Rehab then centers on progressive strength training for the muscles that position and move the shoulder blade, combined with flexibility work where needed. Programs build from control drills to loaded, sport-specific or work-specific movements so you can keep doing what you enjoy.
We also address the factors around recovery, including training load, sleep, and any related shoulder problems. If an underlying tendon or joint issue is found, it is treated alongside the movement retraining. A nerve injury that does not recover may need specialist or surgical input, and we help coordinate that.
What to expect at your visit
- 1.
We listen first
Your visit opens with a real conversation: how the problem started, what you have already tried, and the activity you want back.
- 2.
Exam and in-office ultrasound
A hands-on exam, then ultrasound at the exam table, often while you move, so your physician can see the tendon, joint, or nerve involved.
- 3.
A clear diagnosis and plan
You leave knowing what is wrong and what your options are, from strength-based rehab to procedures, and why we recommend each one.
- 4.
Treatment and follow-through
Most procedures happen here in the office. We coordinate with your physical therapist and check progress against the goals you set.
Questions about scapular dyskinesis
- Can scapular dyskinesis be fixed with exercise?
- In most cases, yes. A targeted strengthening and control program is the main treatment and often improves both movement and pain.
- What does a winging shoulder blade mean?
- Winging means the inner edge of the shoulder blade lifts away from the ribs. It is often due to weak or poorly coordinated muscles, but it can also come from a nerve injury, which may need nerve testing.
- Why does my shoulder blade affect my shoulder pain?
- The shoulder blade is the base the arm moves from. When it does not move well, the shoulder joint and tendons take on uneven load, which can lead to pain and irritation.
