Abstract
Background: Shoulderstability is very important for distal hand mobility and this concept may affect the performance of tennis players. Shoulder rotators have important role in shoulder joint stability.Purpose: This study was to investigate the correlation between shoulder torque and hand grip strength in Egyptian tennis players.Design of the study : Correlational one-shot study. Subjects: Eighty-four players from both genders with age ranging from 17 to 25 yearswere assigned to one group.Methodology: Hand grip dynamometer was used for measuring grip strength and isokinetic machine was used for measuring shoulder torquefor internal and external rotators. Results: There was significant correlation between hand grip strength and shoulder internal rotators{u2019}peak torque (r = 0.81, p = 0.0001) andsignificant correlations between hand grip strength and shoulder external rotators{u2019} peak torque (r = 0.89, p = 0.0001). Conclusion: There was a significant correlation between hand grip strength and shoulder torque in tennis players
