Summary
Improvement in shoulder function is linked to better scapular dyskinesis in patients with subacromial shoulder pain. This study highlights a connection between altered shoulder blade movement and functional recovery.
Area of Science:
- Orthopedics
- Sports Medicine
- Rehabilitation Science
Background:
- Subacromial shoulder pain is a common condition affecting shoulder function.
- Scapular dyskinesis, an abnormal scapular movement pattern, is often observed in individuals with shoulder pain.
- The relationship between scapular dyskinesis and clinical outcomes like pain and function requires further elucidation.
Purpose of the Study:
- To investigate the association between changes in pain and shoulder function and changes in scapular dyskinesis.
- To assess if improvements in scapular movement correlate with reduced pain and enhanced function in patients with subacromial shoulder pain.
Main Methods:
- Forty-four participants with subacromial shoulder pain were evaluated at baseline and after 8 weeks.
- Pain was measured using the Numeric Pain Rating Scale (NPRS), and function was assessed with the Patient-Specific Functional Scale (PSFS).
- Scapular dyskinesis was evaluated using a standardized observational test, and changes were correlated with pain and function outcome changes.
Main Results:
- A moderate negative correlation (r = -0.4) was observed between improvements in shoulder function and improvements in scapular dyskinesis.
- No significant association was found between changes in resting pain (r = -0.1) or pain during movement (r = 0.28) and changes in scapular dyskinesis.
Conclusions:
- Improved shoulder function in patients with subacromial shoulder pain is associated with improvements in scapular dyskinesis.
- Further research is warranted to explore a potential causal relationship between the correction of scapular dyskinesis and functional recovery in shoulder conditions.
