Effects of Shoulder Stabilization Exercises with Hand Grip on Pain, Muscle Strength, Range of Motion, and Shoulder Function in Patients with Shoulder Impingement Syndrome

Objective: This study aimed to investigate the effects of shoulder stabilization exercises combined with hand gripson shoulder pain, muscle strength, range of motion (ROM), and function in patients with shoulder impingement syndrome Design: Repeated Measures Design Methods: Twenty-two patients with shoulder impingement syndrome were randomly assigned to either the SSEG group (shoulder stabilization exercise with hand grips) or the GSE group (general shoulder stabilization exercise).Both groups participated in an exercise program three times per week for 4 weeks.The outcome measures included pain intensity (VAS), internal and external rotation strength of the shoulder, active shoulder ROM, and functional scores using the Disabilities of the Arm, Shoulder, and Hand (DASH) and Shoulder Pain and Disability Index (SPADI).Results: The groups were comparable at baseline.Pain and strength improved in both groups; however, the SSEG showed greater pain reduction and larger gains in shoulder rotator strength (internal/external) than the GSE group (p<0.05).Range of motion and function (DASH andSPADI) improved in both groups, with no between-group differences seen at posttest or in the change scores (p>0.05).Conclusions: Shoulder stabilization exercises combined with hand grips may be more effective than general stabilization exercises in reducing pain and improving strength in patients with shoulder impingement syndrome.These findings suggest that the incorporation of hand grip activation into stabilization exercises may have clinical benefits in shoulder rehabilitation.
