Objective: This study evaluated the effect of theraband training on Position sense of internal and external rotator muscles in male athletes with shoulder impingement syndrome.

Materials & Methods: In this semi-experimental interventional study 30 cases of men with Shoulder syndrome with age range of 20 to 30 years participated. They were divided in test and control groups, each group including 15 people through non-random and purposeful method Biodex System 3 Made in America was used to measure position sense of internal and external rotator muscles. For data analysis independent 7 paired t-test was used in SPSS software (version 21).

Results: The experimental group showed significant improvement after six weeks of theraband training in the internal and external rotator muscles in three 90,45,0 degree angle at a significance level of 0.05 (P=0.05).

Conclusion: The results of this study showed that of theraband training resulted in improved position sense of internal and external rotator muscles in male athletes with impingement syndrome thus, the benefits of these exercises can be used widely in team sports and also for easy and quick rehabilitation of patients.
