The study aimed to compare the efficacy of modified sleeper stretch and modified cross-body adduction stretch in improving shoulder internal rotation range of motion and upper limb function. Thirty male lawn tennis players aged between 20 to 35, with more than 150 glenohumeral internal rotation deficiency (GIRD) on the dominant shoulder (compared to the nondominant side) participate in the study and divided into two groups (A and B). Group A received a modified sleeper stretch and group B received a modified cross-body adduction stretch for four weeks, five times per week. The outcome measures were the internal rotation range of motion measured by a universal goniometer and upper limb functions measured by the Disability of the Arm, Shoulder, and Hand (DASH) scale.

Inclusion Criteria:

• Lawn Tennis Players

Exclusion Criteria:

• systemic or metabolic disorders
