Correlation between scapular alignment and upper extremity function in children with hemiparetic cerebral palsy

Area of Science:

• Pediatric rehabilitation
• Movement science
• Neurology

Background:

• Spastic hemiplegic cerebral palsy (CP) affects motor function in children.
• Scapular alignment is a critical component of shoulder girdle biomechanics.
• Understanding the relationship between scapular alignment and upper extremity function in pediatric CP is essential for targeted interventions.

Purpose of the Study:

• To investigate the relationship between scapular alignment and upper extremity function in children with spastic hemiplegic cerebral palsy.
• To assess the degree of scapular upward rotation and its correlation with functional outcomes.

Main Methods:

• Eighty-five children (3-6 years) with spastic hemiplegic CP participated.
• Scapular upward rotation was measured using Postural Zone software.
• Upper extremity function was evaluated using the Pediatric Arm Function Test.

Main Results:

• A significant difference in scapular upward rotation was observed between the affected and less affected sides.
• Upper extremity function was significantly lower on the affected side compared to the less affected side.
• Strong negative correlations were found between scapular upward rotation and upper extremity function scores, indicating impaired function with reduced rotation.

Conclusions:

• Reduced upward scapular rotation on the affected side is a key finding in children with hemiplegic CP.
• Scapular alignment and symmetry play a significant role in upper extremity function.
• Correction of scapular deviations may be a valuable component of rehabilitation programs for this population.
