Scapular dyskinesis is an alteration or deviation in the normal resting or active position of the scapula during shoulder movement.
Understanding Scapular Dyskinesis
Scapular dyskinesis, sometimes referred to as SICK scapula syndrome, involves abnormal movement or positioning of the scapula (shoulder blade). This condition occurs when the scapula doesn't move correctly in relation to the rib cage and shoulder joint. It is not a diagnosis itself, but rather a description of an altered movement pattern, often resulting from other underlying issues.
Key Characteristics:
- Abnormal Movement: The scapula may wing out, tilt forward, or rotate incorrectly during arm movements.
- Altered Resting Position: The scapula might sit in an unusual position even when the arm is at rest.
- Pain and Discomfort: While the dyskinesis itself might not directly cause pain, it's often associated with pain and shoulder issues like impingement, instability, and rotator cuff problems.
Causes of Scapular Dyskinesis:
Any injury around the shoulder can affect the scapula's position and movement. Some common causes include:
- Muscular Imbalances: Weakness or tightness in muscles surrounding the shoulder blade and shoulder.
- Example: Weakness in the serratus anterior muscle can lead to a "winging" scapula.
- Nerve Issues: Problems with nerves that control the muscles around the scapula.
- Bony or Soft Tissue Injuries: Injuries like rotator cuff tears, labral tears, or fractures.
- Poor Posture: Habitual poor posture can lead to altered scapular mechanics.
- Overuse: Repetitive overhead activities can contribute to muscle imbalances and dyskinesis.
Impact of Scapular Dyskinesis:
When the scapula doesn't move correctly, it affects the entire shoulder complex:
- Shoulder Pain: Abnormal mechanics can increase stress on the shoulder joint.
- Reduced Range of Motion: Limited or painful movements.
- Impaired Athletic Performance: Difficulty with throwing, swimming, and other overhead sports.
- Increased Risk of Injury: Increases the likelihood of shoulder injuries.
Addressing Scapular Dyskinesis:
Physical therapy and exercises focused on:
- Strengthening: Targeted exercises for weak muscles around the shoulder blade (e.g., serratus anterior, lower trapezius, rhomboids).
- Stretching: Improving flexibility of tight muscles (e.g., pectoral muscles).
- Postural Correction: Improving overall posture can positively impact scapular movement.
- Proper Movement Patterns: Retraining proper scapular mechanics during activities.
| Feature | Description |
|---|---|
| Definition | An alteration or deviation in the normal resting or active position of the scapula during shoulder movement. |
| Symptoms | Often pain and limited range of motion in the shoulder |
| Causes | Muscular imbalances, nerve issues, injuries, poor posture |
| Treatment | Physical therapy, strengthening, stretching, and postural correction |
Scapular dyskinesis is a complex issue that often requires a thorough assessment by a qualified healthcare professional. Early diagnosis and proper treatment can improve shoulder function and alleviate pain.
