What it is
Shoulder and scapular dyskinesis is the altered position and motion of the shoulder blade and upper arm during elevation and rotation. In throwers and lifters, it increases elbow load because the forearm lags behind a poorly stabilised shoulder. The elbow then manages the torque that should be shared higher up the chain.
Improving scapular upward rotation, posterior tilt, and rotator cuff strength reduces medial and posterior elbow stress.
What happens when it occurs
The scapula fails to set or rotate on time. The humeral head rides upward, and rotation occurs late. The elbow is forced to produce speed without a stable base. Restoring scapular control and cuff strength changes load distribution immediately.
Common causes and risk factors
- Low serratus anterior and lower trapezius endurance
- Thoracic stiffness
- High pressing compared with pulling in the gym
- Previous shoulder or neck pain
Who is most affected
Throwers, swimmers, and lifters who have taken time off or who favour pressing exercises.
Typical symptoms
- Elbow pain late in cocking or at release
- Upper shoulder fatigue with overhead work
- Visible winging or shrug with elevation
When to seek care
If elbow pain persists despite forearm care or if overhead tasks remain limited.
How we diagnose
Movement observation, scapular assistance and reposition tests, cuff strength testing, and thoracic mobility screens. Imaging is seldom required unless structural shoulder pathology is suspected.
Management
- Serratus anterior and lower trapezius progressions
- External rotation strength and endurance
- Thoracic mobility and posture coaching
- Throwing or lifting technique integration
Rehabilitation milestones
Phase 1 weeks 0 to 3: activation, wall slides, prone Y and W variations.
Phase 2 weeks 3 to 8: heavy slow rows, external rotation loading, endurance holds.
Phase 3 weeks 8 to 16: overhead capacity, plyometric drills, sport skills.
Phase 4 months 4 to 6: maintenance and performance blocks.
Readiness to progress
- Smooth scapular motion on video review
- External rotation strength within 90 per cent
- No next-day increase after overhead sessions
Prevention
- Balance pressing with pulling
- Keep the serratus and lower trapezius endurance high
- Break up long sitting with mobility sets
Australia snapshot
- Regular in swimming, throwing, and strength communities
- Desk-based workers feature due to low thoracic mobility
- Rehabilitation services are accessible in most metropolitan areas
Latest insights
Stable blades create friendly elbows.
Rows and external rotations are non‑negotiable staples.
