Background: Glenohumeral Internal Rotation Deficit (GIRD) is common in overhead athletes and is associated with Posterior Shoulder Tightness (PST). These mobility restrictions in the shoulder are common in amateur basketball players as they are used extensively in their sport due to a lot of overhead movements. Although early identification and management are paramount, the co-prevalence of PST and GIRD in this population is largely underreported.
Objective: This study aimed to determine the prevalence of posterior shoulder tightness and its association with glenohumeral internal rotation deficit among amateur basketball players.
Methods: This was a cross-sectional observational study on 60 amateur basketball players aged 18–25 years. Glenohumeral internal rotation range of motion (IR-ROM) was measured (with a goniometer) and horizontal adduction test was used to assess posterior shoulder tightness. However, the relationship between PST and GIRD was evaluated by descriptive statistics, chi-square test, t-test, and logistic regression analysis.
Results: The study found that 43.3% of participants exhibited PST and the statistical analyses showed strong impact of PST on the likelihood of developing substantial glenohumeral internal rotation deficits (p < 0.001).
Conclusion: In amateur basketball players, this study demonstrates a significant relationship between posterior shoulder tightness and glenohumeral internal rotation deficit. These findings underscore the importance of early detection and targeted intervention for PST, to address and mitigate potential consequences such as GIRD in overhead athletes.
