| Resumo: | Introduction: Overhead sports overload the shoulder complex mainly due to the
repetition of throwing movements at high speeds, which may cause some adaptations in
the athlete’s shoulder, and might increase the risk of developing shoulder pain. Moreover,
it has been considered nowadays the influence of alterations throughout the kinetic chain
as risk factor to injuries in the shoulder complex. Objective: to compare alterations in
osseous, muscular and joint system and the function of shoulder complex, core and hip in
overhead athletes with and without shoulder pain. Methods: This is an observational
study, in which 41 handball and volleyball athletes were assessed. The athletes were
assigned to two groups according to their shoulder pain: no pain group (NPG) (n: 20, age:
21,2±3,1 years and BMI: 23,3±3,2 kg/m2
) and pain group (PG) (n: 21; age: 23,6±3,7 years
and BMI: 25,02±3,9 kg/m2
), based on pain and function self-reported through the Penn
Shoulder Score (PSS) and Disabilities of the arm, shoulder, and hand (DASH)
questionnaires. The individuals underwent an assessment of range of motion (ROM) of
shoulder (rotation, horizontal adduction, low flexion, and humeral retroversion), hip
(rotation) and trunk (flexion, extension, and lateral flexion), strength of glenohumeral
(rotators), scapular (lower trapezius and serratus anterior), hip (abductors and extensors)
and trunk (rotators, extensors and lateral flexors) muscles, besides endurance of the trunk
(flexors, extensors and lateral flexors) and functional performance of lower and upper
limbs through the Y balance test. Data were analyzed in a descriptive and inferential
manner through SPSS 20.0, with a 95% confidence interval and a p<0,05 was considered
statistically different. Results: Athletes from the pain group showed smaller external
rotation (ER) (p<0,01) and total rotation (p<0,01) ROM in the dominant shoulder, smaller
horizontal adduction (p<0,01) in non-dominant shoulder, smaller hip internal rotation
(IR) in dominant and non-dominant hips (p<0,01), and less trunk flexion ROM (p<0,01).
PG also showed less strength of trunk extension (p=0,01), short endurance time for trunk
extensors (p=0,02) and flexors (p<0,01), decreased reach distance for both lower limbs
in the anterior direction (p<0,05), decreased reach distance in the posteromedial
direction(p=0,04) for the dominant lower limb, as well as smaller composite score for
both limbs (p<0,05). Moreover, for limbs comparison, the dominant limb of the PG
showed smaller ROMs of shoulder IR(p<0,01) and total ROM (p<0,01), of horizontal
adduction (p=0,04) and low flexion(p=0,01), besides decreased reach distance in the
superolateral direction in the upper quarter Y balance test. As for the NPG the dominant limb showed higher shoulder ER ROM (p=0,03), and smaller values for shoulder IR ROM (p=0,02), horizontal adduction (p=0,01) and low flexion (p<0,01). Conclusion: Overhead athletes with shoulder pain show changes in ROM throughout the kinetic chain, besides lower core endurance, and decreased functional performance in the lower limbs. |
