Background: Overhead athletes present with posterior shoulder tightness and decreased internal rotation because of osseous and soft tissue adaptations.Muscle Energy Technique has been successfully used in lengthening the soft tissues and improves range of motion. No studies have explored the effectiveness of muscle energy technique on Glenohumeral Internal Rotation Deficit in overhead athletes.
Objective: To find out the effect of muscle energy technique on improving Glenohumeral Internal Rotation Deficit and functional outcomes in overhead athletes.
Methodology: This study was carried out with 40 patients who had Glenohumeral internal rotation deficit. Group A (n = 20) had received muscle energy technique. Group B (n = 20) underwent stretching program. All patients received two treatment sessions per week for four weeks. Glenohumeral internal range of motion was evaluated by goniometer and functional outcomes were evaluated by using Shoulder pain and disability index (SPADI), which were recorded at base line and at the end of four weeks.
Results: Both muscle energy technique and the stretching program were found to be significantly effective in increase Glenohumeral internal range of motion and also reduce the disability and improve functional outcomes. In the experimental group the SPADI was reduced from 61.75 to 57.60 which was statistically significant (p value 0.001) and the IROM was improved from 55.30 to 59.05 which was statistically significant (p value 0.0001). In the control group the SPADI was reduced from 62.45 to 60.50 which was statistically significant (p value 0.007) and the IROM was improved from 55.65 to 57.50 which was statistically significant (p value 0.005)
Conclusion: The results of this study demonstrate that the muscle energy technique and stretching program may be the treatment choice for therapist in managing Glenohumeral internal rotation deficit.
