Summary

A new test for scapular dyskinesis demonstrated satisfactory interrater reliability in overhead athletes. This finding supports its clinical use for detecting abnormal scapular motion and potential shoulder injury risk.

Area of Science:

  • Sports Medicine
  • Biomechanics
  • Clinical Assessment

Background:

  • Scapular dyskinesis is a suspected contributor to shoulder injuries in overhead athletes.
  • Existing evidence linking abnormal scapular motion to injury is inconsistent.
  • Reliable clinical tools for identifying scapular dyskinesis are currently lacking.

Purpose of the Study:

  • To evaluate the interrater reliability of a novel clinical test designed to detect abnormal scapular motion.

Main Methods:

  • A correlational design was employed, with multiple pairs of raters assessing scapular motion.
  • 142 collegiate athletes participating in overhead sports were videotaped performing specific arm movements.
  • Six raters, trained on standardized definitions, independently evaluated videotapes for scapular winging or dysrhythmia.

Main Results:

  • Interrater agreement ranged from 75% to 82%.
  • Weighted kappa coefficients (kappa(w)) for reliability were between 0.48 and 0.61.
  • These results indicate satisfactory reliability for the tested scapular dyskinesis assessment.

Conclusions:

  • The developed test for scapular dyskinesis exhibits adequate reliability for clinical application.
  • This tool can aid in the assessment of overhead athletes at higher risk for shoulder pathologies.
  • Further validation may enhance its diagnostic utility in sports injury prevention.
