Resumen


Abstract

The aim was to evaluate the internal rotation, external rotation and total range of motion of shoulder in professional rugby players and associated factors. 104 rugby players and 30 healthy volunteers were interrogated and clinically examined. 19.23% of the rugby players were excluded by history of shoulder luxation or surgery. 84 rugby players with 24.28±5.37 years old were finally included in the study. The groups were analyzed with Mann-Whitney test, Fisher’s exact test, Linear Regression and a Logistic Regression. It was found that professional rugby players had less internal, external and total range of glenohumeral rotation compared with control group. In the Logistic Regression, the age is a risk factor for external rotation range deficit (Odds Ratio= 1.58). Instead, the years of experience are a protector factor (Odds Ratio= 0.63). We can conclude that glenohumeral rotation range is diminished in professional rugby players and is associated with age and years of experience.

Key words: rugby; shoulder; glenohumeral rotation range deficit; collision sports.

Resumen

El objetivo de este estudio fue evaluar la rotación interna, rotación externa, el rango total de movimiento del hombro y factores asociados en jugadores de rugby profesional . 104 jugadores de rugby y 30 voluntarios sanos fueron interrogados y examinados clínicamente. Un 19.23% de los jugadores de rugby fueron excluidos por historial de luxación o cirugía de hombro. 84 jugadores de rugby, con 24.28 ± 5.37 años de edad fueron finalmente incluidos en el estudio. Los grupos se analizaron con la prueba de Mann-Whitney, la prueba exacta de Fisher, regresión lineal y regresión logística. Se encontró que los jugadores profesionales de rugby tienen menos rango de rotación interna, externa y total en comparación con el grupo control. En la regresión logística, la edad es un factor de riesgo de déficit de rotación externa (OR = 1.58). En cambio, los años de experiencia son un factor protector (OR = 0.63). Podemos concluir que el rango de rotación glenohumeral está disminuido en jugadores de rugby profesional y se asocia con la edad y los años de experiencia.

Palabras clave: rugby; hombro; déficit de rotación glenohumeral; deportes de colisión.
