dc.description.abstract
Introduction The "Glenohumeral Internal Rotation Deficit (GIRD)" is known as the difference in internal rotation range of motion (IRRM) between the dominant and non-dominant shoulder of overhead athletes as a result of asymmetric loading. As in contrast loading pattern in gymnastics are quite symmetric and structural changes often occur bilaterally, the question arises if GIRD might develop bilaterally in gymnasts as one source of common bilateral shoulder pathologies and to search for underlying structural adaptations. Materials and methods A group of 35 elite gymnasts (8-24 years) were recruited from a local Olympic Training Centre and compared to a paired cohort of 28 non-overhead athletes. Clinical examinations, digital range of motion (ROM)-measurement, ultrasonographic humeral torsion measurement, and standardized MRI scans of both shoulders were obtained and examined for structural pathologies, cross-sectional areas (CSA) of the rotator cuff muscles and capsular thickness. Results ROM-measurements showed significant decrease in IRRM in the gymnasts groups by age, with IRRM of 48.6 degrees (SD: 8.4 degrees, CI 95%: 43.0-54.3 degrees) at age group 1 (8-10 years) and IRRM of 10 degrees (SD: 11.4 degrees; CI 95%: 0-22.0 degrees) at age group 4 (18-26 years), that was statistically significant for the entire cohort (p = 0.017) compared to the controls. CSA were not significantly different between the cohorts, while there was a slightly increased humeral retrotorsion in the gymnasts as well as a statistically significant posterior capsular thickening. Conclusion A new bilateral form of GIRD was identified in higher age groups of youth and senior elite gymnasts enrolled in this study. Despite to former definition of GIRD there was no compensatory increase in external rotation range of motion (ERRM) but an association with posterior capsular thickening, while there was no periscapular muscle hypertrophy. Humeral retrotorsion was also slightly increased in the gymnasts group.
