Effects of adding core stability training to conventional rehabilitation protocol on shoulder function after rotator cuff repair

Abstract

Background. Rotator cuff tear (RCT) is a prevalent cause leading to shoulder disability and is widely recognized as one of the primary causes of pain as well as dysfunction in the shoulder. The core stabilization exercise program improved the strength of the shoulder muscles. The core stability training (CST) may be utilized during the early phases of shoulder rehabilitation. Purpose. To assess the impacts of adding CST to the conventional rehabilitation protocol on function, proprioception, as well as range of motion (ROM) of shoulder joint following rotator cuff repair (RCR). Methods. Fifty-two participants after RCR were assigned to two groups in a random manner; group I (n = 26) and group II (n = 26). Participants in groups I and II were engaged in a conventional rehabilitation protocol for 12 weeks after RCR. Group II additionally performed CST after the 8th week until the 12th week of RCR. Outcome measures were shoulder function using the Arabic shoulder pain and disability index (SPADI), shoulder joint position sense (JPS) (proprioception accuracy through detecting absolute angle of error) using digital inclinometer, ROM in shoulder flexion, abduction, internal rotation, as well as external rotation using the digital inclinometer. Unpaired t-test, chi square, and MANOVA test were implemented for data analysis. Results. Compared to the pre-treatment condition, the post treatment results revealed that there were statistical substantial improvements (p < 0.05) in SPADI score, absolute angle of error, and ROM flexion, abduction, external rotation and internal rotation) in both groups, even though there were substantial differences among both groups at all post-treatment measures (p < 0.05) in favor of group II. Conclusion. Incorporating CST into the conventional rehabilitation protocol after RCR leads to notable enhancements in shoulder joint function, proprioception, and ROM for flexion, abduction, internal rotation, as well as external rotation.
