Summary

The scapular dyskinesis test accurately identifies abnormal scapular motion in athletes. However, this study found no link between scapular dyskinesis and shoulder symptoms in overhead athletes.

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Biomechanics

Background:

  • Clinical detection of scapular dyskinesis lacks robust validity evidence.
  • Scapular dyskinesis is an abnormal scapular movement pattern.
  • Understanding its clinical assessment and impact on shoulder symptoms is crucial.

Purpose of the Study:

  • To validate the scapular dyskinesis test, a visual assessment tool.
  • To investigate the relationship between scapular dyskinesis and shoulder symptoms in athletes.

Main Methods:

  • A validation study comparing 3D motion analysis with visual assessment of scapular dyskinesis.
  • 142 collegiate athletes in overhead sports were assessed.
  • 66 athletes underwent 3D electromagnetic kinematic testing.

Published on: March 12, 2021

Main Results:

  • Significant differences in 3D scapular motion were observed between normal and dyskinesis groups.
  • Obvious dyskinesis correlated with reduced upward rotation and clavicular elevation, and increased protraction.
  • No significant association was found between scapular dyskinesis and shoulder symptoms (OR=0.79).

Conclusions:

  • The scapular dyskinesis test demonstrates validity in detecting altered 3D scapular motion.
  • Scapular dyskinesis was not found to be related to shoulder symptoms in this cohort of overhead athletes.
