Objective: Glenohumeral Internal Rotation Deficit is one of the important risk factors in throwing athletes that can cause adverse effects on glenohumeral joint biomechanics during throwing activity and overhead activity.
Methods: In this descriptive study, 30 male student Hanballers (age=18 to 25 years) were categorized into healthy (n=15) and Glenohumeral Internal Rotation Deficit (n=15) groups. Upper quarter y balance test (YBT-UQ) was used for measuring functional instability of dominant shoulder. MANOVA test was run for comparing the performances of the two groups.
Results: In all directions, the stability of the shoulder in Hanballer with Glenohumeral Internal Rotation Deficit was significantly lower than that in the healthy group.
Conclusion: Based on the results of this study, functional stability of the unstable shoulder of Hanballers with Glenohumeral Internal Rotation Deficit is lower than the functional stability of the healthy subjects; therefore, we suggest that the upper extremity stabilization exercises, specially the closed kinetic chain exercises be added to the shoulder rehabilitation programs.
