| Resumo: | Introduction: Overhead sports submit the athlete's shoulder to great speeds and range of motion (ROM). The force discharged into the ball is transmitted through the kinetic chain. Over time, the practice of these sports can lead to adaptations that are associated with the shoulder pain and increased risk of shoulder injury. Function assessment tools have been used for screening or monitoring the treatment of athletes, through performance tests and self-report measures. Objective: To investigate the relationship between functional performance of the upper limb and self-reported function, and the relationship between these two measures of function and the clinical variables of the shoulder complex and trunk in overhead athletes with shoulder pain. Methods: Cross-sectional study, carried out with volleyball and handball athletes. We evaluated the function of the dominant upper limb using the Brazilian version of the Penn Shoulder Score and the Disabilities of the Arm, Shoulder and Hand; we evaluated the ROM of lateral and medial rotation of the shoulder, and the measures of horizontal adduction, low flexion and humeral retroversion; ROM of flexion, extension and lateral flexion of the trunk; the isometric strength of lateral and medial rotators of the shoulder, anterior serratus and lower trapezius; and of rotators, extensors and lateral flexors of the trunk; the resistance of the trunk muscles (flexors, extensors and lateral flexors); and evaluated for functional performance using the Upper Quarter Y Balance Test (UQYBT). The data were analyzed using SPSS 20.0, with p <0.05 being adopted. Pearson's correlation test was used to assess the relationship between the variables studied. Results: The study included 21 individuals between 18 and 40 years old (23.6 ± 3.7) with dominant shoulder pain measured through questionnaires. There was a moderate and positive correlation between the superolateral reach and the anterior serratus force (r = 0.45; p = 0.04); of the inferolateral reach with the anterior serratus force (r = 0.53; p = 0.01), with the lower trapezoid force (r = 0.50; p = 0.02), with the rotation force trunk (r = 0.49; p = 0.03), and with lateral trunk flexion strength (r = 0.56; p = 0.01); and the composite score with the anterior serratus force (r = 0.52; p = 0.02), with the lower trapezium force (r = 0.48; p = 0.03), with the rotation force of the trunk (r = 0.45; p = 0.04), and with the lateral flexion strength of the trunk (r = 0.51; p = 0.02). Conclusion: The functional performance at UQYBT was positively and moderately related to the strength of the scapular stabilizing muscles (anterior serratus and lower trapezius) and to the strength of the rotators and lateral trunk flexors. The self-report function measures have no significant relationship with the performance of the UQYBT, nor with the clinical variables of the shoulder and trunk studied. |
