Objective: The aims of this study were (a) to compare shoulder functional performance, shoulder functionality, grip strength, and scapular endurance between individuals with rotator cuff repair (RCr) and healthy controls, and (b) to investigate the impact of these factors on shoulder performance.
Methods: In this study, a study group (n=32) of individuals with RCr and a control group (n=32) of healthy individuals were included. The study group comprised individuals who underwent surgical repair for full-thickness rotator cuff (RC) ruptures (excluding massive size) and completed at least 24 weeks of postoperative follow-up. Shoulder performance and functionality, grip strength, and scapular endurance were evaluated by the Functional Impairment Test-Hand-andNeck/Sh oulder/Arm (FIT-HaNSA), the Modified Constant–Murley Score (MCMS), the Jamar hand dynamometer, and the Scapular Muscle Endurance Test, respectively. These factors affecting the performance of the shoulder were examined by regression analysis.
Results: Functional Impairment Test-Head and Neck, Shoulder, Arm, the MCMS, and the Jamar score were lower in the study group (P < .05). Scapular endurance was similar in both groups (P > .05). Functional Impairment Test-Head and Neck, Shoulder, Arm was correlated with the MCMS, the Jamar score, and the scapular endurance, respectively (r: 0.455 / 0.727 / 0.438; P < .05). A regression analysis was run to determine the variables affecting shoulder performance. The values of pain, strength, total score of MCMS, scapular endurance, and Jamar score explained 14.8%, 29.5%, 27.3%, 18.9%, and 30.8% of shoulder performance, respectively (P < .05).
Conclusion: The functional performance of the shoulder was lower in individuals with RCr compared to healthy individuals. The most significant variables affecting shoulder performance were upper limb strength, shoulder functionality, scapular muscle endurance, and the pain sub-parameter of MCMS, according to the rates of influence, respectively
