| Summary: | Introduction: Glenohumeral Internal Rotation Deficit (GIRD)
indicates a 15° or greater loss of internal rotation of the throwing
shoulder compared with the non-dominant shoulder.
Aim: To estimate the prevalence of GIRD in collegiate overhead
sports player and determine whether GIRD is associated with
scapular dyskinesia and rotator cuff strength ratio.
Materials and Methods: The present study was a Crosssectional study. A total of 127 collegiate athletes were assessed
for passive range of motion, external to internal rotation strength
ratio (ER/IR ratio) and scapular dyskinesia for the throwing
and non-throwing shoulder. Internal and external rotation of
shoulder was measured using an inclinometer with the subject
in prone and arm abducted to 90°. Scapular dyskinesia was
measured using Lateral Scapula Slide test (LSST) and external
to internal rotator strength was measured using a held hand
isometric dynamometer. Chi-square test was used to find the
association between GIRD and scapular dyskinesia and rotator
cuff strength ratio.
Results: Prevalence of GIRD (n=37) was found to be 29.1%.
GIRD was not found to be associated with Scapular dyskinesia
(p=0.237) and ER/IR strength ratio (p=0.411).
Conclusion: Prevalence of GIRD in collegiate athletes playing
overhead sports was found to be 29.1% and there was no
association of GIRD with scapular dyskinesia, rotator cuff
strength ratio. |
