Brief Summary

78 overhead athletes with Glenohumeral Internal Rotation Deficit (GIRD) will be included in this study. Participants will be randomly divided into 3 different groups of 26 people. In each group will be applied posterior shoulder stretching exercises (PSSE) performed with different Muscle Energy Techniques (MET).

Conditions

Glenohumeral Internal Rotation Deficit

Outcome Measures

Primary Outcomes (1)

• Shoulder internal rotation range of motion

  baseline, 6 weeks of training, at the 1st, 3th and 6th months

Secondary Outcomes (10)

• Subacromial space

  baseline, 6 weeks of training, at the 1st, 3th and 6th months

• Posterior shoulder tightness

  baseline, 6 weeks of training, at the 1st, 3th and 6th months

• Shoulder Total rotation range of motion

  baseline, 6 weeks of training, at the 1st, 3th and 6th months

• Functional Throwing Performance Index

  baseline, 6 weeks of training, at the 1st, 3th and 6th months

• Posterior capsule thickness

  baseline, 6 weeks of training, at the 1st, 3th and 6th months

Other: Static Stretching Group Group

Interventions

Post Isometric Relaxation Group OTHER

Athletes will be positioned in a modified cross-body position. They will be asked to actively bring their underlying arm in the direction of horizontal adduction up to the physiological barrier barrier. The participants will be asked to perform an isometric contraction for 5 seconds in the horizontal abduction direction with 20% of the maximum muscle strength. After the relaxation, the arm will be moved towards horizontal adduction and 15 seconds active-assistive stretching will be applied. Participants will be given a 5-second rest period between contractions.This stretching exercise will be applied in 5 repetitions in one session for 6 weeks 5 times a week.

Post Isometric Relaxation Group

Isolytic Stretching Group OTHER

Athletes will be positioned in a modified cross-body position. They will be asked to actively bring their underlying arm in the direction of horizontal adduction up to the physiological barrier barrier. The participants will be asked to perform a contraction in the horizontal abduction direction with 20% of the maximum muscle strength. When the muscle contraction occurs, the arm will be moved quickly in 2-4 seconds towards horizontal adduction and 15 seconds active-assistive stretching will be applied. Participants will be given a 5-second rest period between stretches. This stretching exercise will be applied in 5 repetitions in one session for 6 weeks 5 times a week.

Isolytic Stretching Group

Static Stretching Group Group OTHER

Athletes will be positioned in a modified cross-body position. They will be asked to actively bring their underlying arm in the direction of horizontal adduction up to the physiological barrier. Then, the arm will be moved towards horizontal adduction and 15 seconds active-assistive stretching will be applied. Participants will be given a 5-second rest period between stretching exercises. This stretching exercise will be applied in 5 repetitions in one session for 6 weeks 5 times a week.
