Abstract
Study design: Randomized control trial. Objective: To measure the effect muscle energy technique(MET) for the glenohumeral joint external rotators to improve the range of motion and strength of internal rotators in athletes with glenohumeral internal rotation deficit (GIRD). Background: Glenohumeral internal rotation deficit is one of the leading causes of impairments in overhead throwing athletes. Anatomical GIRD is though considered to be normal in overhead athletes but it may further lead to osseous and capsuloligamentous changes in the glenohumeral joint if not treated. The muscle energy technique protocol aimed at improving the range of motion and strength of the internal rotators of the glenohumeral joint. It has been hypothesized that MET will increase the glenohumeral internal rotation ROM and strength in athletes with GIRD. Methods: thirty overhead athletes were conveniently assigned in two groups. MET for glenohumeral joint external rotators (n=15) and stretching for glenohumeral joint external rotators (n=15). We measured the range of motion of glenohumeral joint internal rotation and strength of glenohumeral joint internal rotators, of the dominant shoulder at 0 day, 1st week and 2nd week. At the end of 2nd week data analysis was done using one way ANOVA and post hoc tukey’s test and significant results were found. (p < 0.05). Results: The group treated with MET for the external rotators had a significant increase in internal rotation at the end of 2nd week. The group treated with stretching for external rotators do not showed a significant increase in internal rotation. Conclusion: It is concluded that MET is an effective treatment for increasing the ROM and strength of internal rotation at the glenohumeral joint in asymptomatic overhead athletes. Therefore application of MET for the external rotators may be useful for increasing the ROM as well as strength in overhead athletes.
