Comparative effects of post isometric relaxation and myofascial release on range of motion and disability in volleyball players with glenohumeral internal rotation deficit
The purpose of this study is to compare the effectiveness of Post isometric relaxation and subscapularis release on range of Motion and disability in Volleyball Players with Glenohumeral Internal Rotation Deficit.
Design
Randomized Clinical Trial, Two parallel groups.
Settings and conduct
The data was collected from Volleyball athletes in Pakistan Sports Board, Lahore.
Participants/Inclusion and exclusion criteria
Inclusion Criteria: Age 15 to 30 years, Both male and female, Athlete with GIRD, Novice players.
Exclusion Criteria: Abnormality in body biomechanics, shoulder injury, shoulder surgery, Any systemic pathology, Corticosteroid injection in (GHJ), All participants playing volleyball for 1 year.
Intervention groups
Post-isometric relaxation was given to group A. The participant was then instructed to perform a 5-second isometric contraction in the direction of external rotation, against an opposing force provided by the examiner at the distal forearm. The participant was instructed to internally rotate the arm toward the ground as a 30-second active assisted stretch was applied. The participant was instructed to relax. This protocol was performed for a total of 3 repetitions three times a week for 2 weeks.
Myofascial release to subscapularis was given to group B. Myofascial release to subscapularis application was performed by applying a hot pack for 10 min and also sustain manual pressure with a therapy ball and strengthening exercises of periscapular muscles by a physiotherapist three times a week for 2 weeks.
Main outcome variables
Glenohumeral internal rotation range of motion in volleyball players.

Randomization (investigator's opinion)
Randomized
Randomization description
Participants were selected by non-probability convenience sampling from the college setting. Each participant is allocated a number on enrollment in the study. Participants were randomly allocated into two groups by a random number sequence generated by a computer software program called "research randomizer". According to the number generated by a computer software, the participant is allocated into group in which that number falls. This software is used to generate 2 sets of 20 unique numbers via setting the range from 1-40 from least to greatest order.

Description
Glenohumeral internal rotation range of motion
Timepoint
Before intervention and 2 week after intervention
Method of measurement
We used a manual Goniometer to measure the range of motion of the involved shoulder and DASH (Disabilities of the Arm, Shoulder and Hand) Questionnaire is used to indicate the impact of an impairment on the level and disability.
Secondary outcomes
empty
Intervention groups
1
Description
Intervention group A: Treatment with Post isometric Muscle Energy Technique applied over the period of 2 weeks. Post isometric Muscle Energy Technique application (experimental) to dominant side Glenohumeral joint horizontal abductors. The participant was in a supine position on the examination table. With the humerus supported and the participant’s shoulder and elbow in 90° of abduction and flexion, respectively, the examiner passively moved the humerus into internal rotation until the first barrier of motion was reached. The participant was then instructed to perform a 5-second isometric contraction in the direction of external rotation, against an opposing force provided by the examiner at the distal forearm. Following the contraction, the participant was instructed to internally rotate the arm toward the ground as a 30-second active assisted stretch was applied. The participant was instructed to relax.This protocol was performed for a total of 3 repetitions three times a week for 2 weeks.
