Racquet sports have gained increasing popularity in Asia. In the current study performed on 25 district level male badminton players aging between 18-25 years assessment of GIRD/GERG ratio, strength of internal, external rotators and of upper extremity stability was done on the dominant and non-dominant side. On statistical analysis using paired t-test.The internal and external rotators were stronger on dominant side when compared to the non-dominant side. The internal rotators were stronger than the external rotators on both dominant and non-dominant side. The external rotation range of motion was more than the internal range of motion on the dominant and non-dominant side. GIRD/GERG ratio was significant in badminton players (p>0.0001). Correlational statistics using Spearman’s test showed that the strength of the dominant side external rotators correlated with the CKCUEST.The strength of the non-dominant side external rotators, both side internal rotators and GIRD/GERG ratio did not have any significant correlation with the CKCUEST.
