Brief summary: Glenohumeral internal rotation deficit (GIRD) is common physical deficiency found both teenager and overhead many sports for example baseball, cricket, and tennis. GIRD is generally categorized as simultaneous deficits of internal rotation (IR) and total arc of motion in the dominant side. GIRD causes increase muscle stiffness, capsular changes ( hyperplasia) , muscle imbalance leads to humeral retroversion. The objective of the study will be to Compare the effects of Mulligan internal rotation Mobilization and post isometric relaxation technique on Pain, Range of motion and function in athletes with Glenohumeral Internal Rotation Deficit

This study will be a Randomise Control trial and will be conducted Pakistan cricket board acedmy and in outpatient department of physical therapy, AL REHMAN Hospital Lahore . The study will be completed within the time duration of six months . Convenient sampling technique will be used to collect the data. A sample size of 14 patients will be taken in this study Comparison of Mulligan internal rotation Mobilization and post isometric relaxation technique on Pain and function in athletes with Glenohumeral Internal Rotation Deficit. Patients will be divided into two groups. (Group A will be treated with mulligan MWM AND Sleeper stretch whereas Group B will be treated with post isometic relaxtion technique and sleeper stretch ). SPADI score will be used to ask some questions related to patients symptoms and daily activities and Numeric pain rating scale will be used to measure pain intensity. UNIVERSAL GONIOMETER will be used to measure ROM of shoulder joint All participants of the study will fill the SPADI score and Numeric pain rating scale on day 1 as pre treatment values and at the end of week 2 as post treatment values respectively . The collected data will be analyzed on SPSS 25.

Detailed description: Glenohumeral internal rotation deficit (GIRD) is common physical deficiency found both teenager and overhead many sports for example baseball, cricket, and tennis. GIRD is generally categorized as simultaneous deficits of internal rotation (IR) and total arc of motion in the dominant side.

Tight posterior glenohumeral capsule and posterior muscles such as the posterior deltoid, infraspinatus, and teres minor muscles can leads to GIRD although mechanism is not clear yet. Few research authors propose that repetitive tensile stress to posterior structures in the follow-through phase in throwing movements could lead to inflammation, scar formation, and following tightness in posterior tissues, resulting in PST and GIRD.

Tightness of the posterior shoulder may be a common factor in many shoulder conditions, including impingement syndrome, rotator cuff tears, and labral lesions.Posterior shoulder tightness may cause alterations in shoulder motion or muscle flexibility that are thought to increase risk of injury in athletes.

GIRD causes increase muscle stiffness, capsular changes ( hyperplasia ) , muscle imbalance leads to humeral retroversion.Due to the influence of tightness of the posterior glenohumeral soft tissues on glenohumeral and shoulder kinematics stretching of the posterior glenohumeral tissues to restore glenohumeral IR ROM is a common aspect of shoulder rehabilitation.

GIRD can be measured as the difference in the maximum humeral internal rotation angle between the dominant (throwing) and non-dominant (non-throwing) limbs. A difference of 10-17 degree of internal rotation is common in the dominant arm of throwing athletes who have not suffered any shoulder injury. GIRD greater than 25° has been associated with injuries such as superior labral lesions, subacromial impingement, and pathological internal impingement in the throwing shoulder in dictating a need for investigation of preventative and corrective interventions to restore GHJ internal rotation ROM.

Manual Physical thearpy approaches are very effective in treatment of many musculoskeletal issues. Mulligan manual techniques Introduced by Brain mulligan are very useful treating and correcting joint dysfunction. The mobilization with movement technique has its own parameter. It is done with both therapist patient participation i.e. passive glide is done by physiotherapist at peripheral joint meanwhile patient performs pain free physiologic movement. The stamp of mobilization with movement (MWM) technique is pain should be decreased after the application of technique.

Muscle energy techniques are basically soft tissue osteopathic manipulation which is performed precisely and in controlled manners, patient do isotonic or isometric contractions , they are very useful in function and reduce the pain . MET are mostly indicated in to decrease pain, stretch tight muscles and fascia, reduce muscle tonus, improve local circulation, strengthen weak musculature and mobilize joint restrictions . This leads to improved postural alignment and the restoration of proper joint biomechanics and functional movement.

As per as researcher's Knowledge most of the studies were conducted on over all mobility of shoulder, only few studies worked purely on internal rotation deficit. so this study will be benficient for GIRD.The rationale of this study will be to check the additive effects of Mulligan internal roation mobilization on Pain, Range of motion and function in athletes with Glenohumeral Internal Rotation Deficit beside the application of sleeper stretch a conventional protocol.

In 2018 Sreenivasu Kotagiri and his colleagues conduced a study on effectiveness of Mobilization with Exercise V/S Mulligan Internal Rotation MWM with Stretching in Patient with Glenohumeral Internal Rotation Deficit .They founded mulligan mobilization with posterior capsule stretching is more effective in improving range of motion and function when compared to mobilization with shoulder stabilization exercises alone.

In 2016 Sonakshi Sehgal and her colleague conducted a study to measure the effect muscle energy technique(MET) for the glenohumeral joint external rotators to improve the range of motion and strength of internal rotators in athletes with glenohumeral internal rotation deficit (GIRD). They found that MET can be used to treat limited glenohumeral internal rotation in athletes with GIRD. The study concluded that the treatment showed remarked improvement in the range of motion and strength of internal rotators in athletes with GIRD. Therefore the technique can be used in acute cases of posterior shoulder tightness to prevent the occurrence of other shoulder injuries.

In 2010 Robert C. Manske, and his colleagues worked on Comparison of Stretching Versus Stretching and Joint Mobilization for Posterior Shoulder Tightness Measured by Internal Rotation Motion Loss they concluded cross-body stretch and cross-body stretch plus joint mobilization ,both may be beneficial for those with limited internal rotation range of motion.

In 2013 Hafiz Sheraz Arshad and his colleagues worked on comparison of Mulligan Mobilization with Movement and End-Range Mobilization Following Maitland Techniques in Patients with Frozen Shoulder in Improving Range of Motion, they concluded that end range mobilization following maitland are equally effective as that of mobilization with movement exercises. Effectiveness of end range mobilization following maitland for increasing range of motion and improving pain. This supported their usefulness in improving quality of life due to shoulder dysfunction such as frozen shoulder.

As per as researcher's Knowledge most of the studies were conducted on over all mobility of shoulder, only few studies worked purely on internal rotation deficit. so this study will be benficient for GIRD.The rationale of this study will be to check the additive effects of Mulligan internal roation mobilization on Pain, Range of motion and function in athletes with Glenohumeral Internal Rotation Deficit beside the application of sleeper stretch a conventional protocol.
