Strong core stabilization not only minimizes the load on the vertebral column, but also improves strength and endurance of peripheral joints, and enables the energy transfer to distal segments. Despite the current interest surrounding core stability, none of the studies investigated the effect of core stability on the formation of rotator cuff tear or healing after repair.


To determine the relationship between core stability and upper extremity functional performance in patients who underwent rotator cuff repair surgery and to compare those with healthy subjects of similar age.


Patients who underwent rotator cuff repair (RC repair group, n= 58 patient) and healthy subjects of the similar age group (control group, n= 114) were included in the study. The mean age was 55.03 ± 9.84 years in the RC repair group and 52.71 ± 6.31 years in the control group. The RC repair group took standardized rehabilitation. The rehabilitation program did not include core strength and stability exercise. Core endurance was assessed with Flexor Endurance, Prone Bridge and Supine bridge test. Disabilities of the Arm, Shoulder and Hand (DASH), Short Form-36 (SF-36) and the Close Kinetic Chain Upper Extremity Stability (CKCUES) test were used to evaluate the upper extremity functional performance.


The core endurance (prone and supine bridge test) of the control group was statistically significantly better than the RC repair group (p⩽ 0.005). The DASH-T, SF-36 and CKCUES scores of the control group were also statistically significantly better.


The neuromuscular system should be considered as a whole, and addition of the core stabilization exercises to an effective rehabilitation program after RC repair surgery may be beneficial.
