The Impact of OKC Exercises and TRX Exercises on Shoulder Joint Proprioception in Overhead Athletes With Shoulder Impingement Syndrome: A Randomized Controlled Trial

Purpose: Sub-acromial impingement syndrome (SAIS) is one of the most common causes shoulder pain and affects joint proprioception. The closed kinetic chain (CKC) exercises with sling are more effective safer than open (OKC) exercises. This study aimed to compare effectiveness OKC total-body resistance (TRX) training on position sense (JPS) in overhead athletes (SIS). Methods: article was a randomized control trial (RCT) conducted Kerman City, Iran, 2019. research sample included 33 SIS who were randomly classified into three groups: OKC, sling, groups. Joint evaluated external rotation (ER), internal (IR), abduction dominant arm target angle concerning range motion Leighton flexometer. obtained data analyzed using analysis covariance (ANCOVA). Results: post-intervention results showed that significant difference observed between groups (ER, P<0.001; IR, P<0.001). change group significantly higher ER, except JPS (P=0.001, P=0.001, P=0.235, respectively) (P<0.001, P<0.001, respectively). Change P=0.019, group. exercise improved SIS. Conclusion: for because these CKC performed an unstable level.
