Effect Of Gluteal Activation Training On Shoulder Pain And Rotator Cuff Strength In Overhead Athletes: An Experimental Study

Background:Overhead athletes frequently experience shoulder pain and rotator cuff dysfunction due to repetitive high-velocity movements such as throwing, serving, and smashing. These movements place considerable mechanical stress on the glenohumeral joint and surrounding musculature. Although conventional rehabilitation programs primarily focus on strengthening the rotator cuff and improving scapular stability, emerging evidence suggests that impairments in the proximal kinetic chain may significantly influence shoulder biomechanics. The gluteal muscles play a crucial role in generating force and stabilizing the pelvis during athletic movements. Inhibition or delayed activation of these muscles, commonly referred to as gluteal amnesia, may disrupt the transfer of kinetic energy from the lower extremities to the upper limb, thereby increasing the mechanical load on the shoulder complex.Objective:To evaluate the effect of correcting gluteal amnesia on reducing shoulder pain and improving rotator cuff muscle strength among overhead athletes.Methods:An experimental study was conducted among 60 overhead athletes presenting with shoulder pain related to rotator cuff dysfunction. Participants were divided into two groups with 30 subjects in each group. Group A received conventional shoulder rehabilitation exercises, while Group B received gluteal activation exercises in addition to conventional rehabilitation. The intervention program was conducted for eight weeks under supervised physiotherapy sessions. Outcome measures included the Shoulder Pain and Disability Index (SPADI) for assessment of pain and functional limitation, and manual muscle testing of the gluteus maximus to evaluate muscle strength. Pre-intervention and post-intervention assessments were recorded. Statistical analysis was performed using paired t-test to compare pre- and post-intervention scores within each group, with a significance level set at p < 0.05.Results: Both groups demonstrated improvement in shoulder pain, functional ability, and muscle strength following the intervention period. However, participants who received gluteal activation training showed greater improvement compared to those who underwent conventional rehabilitation alone. Group B demonstrated a larger reduction in SPADI pain and disability scores along with a greater increase in gluteus maximus muscle strength. The statistical analysis indicated significant improvements within both groups, with comparatively higher improvements observed in the gluteal activation group.Conclusion: The findings of the present study suggest that correcting gluteal amnesia through targeted gluteal activation exercises may significantly reduce shoulder pain and improve rotator cuff function in overhead athletes. Incorporating gluteal activation training into shoulder rehabilitation programs may enhance kinetic chain efficiency and contribute to improved functional outcomes in athletes involved in repetitive overhead activities.
