Brief Summary

To examine and compare the effect of a novel stretching technique and traditional stretching on glenohumeral range of motion, strength, maximum voluntary contraction, pain, and subject satisfaction in overhead athletes with glenohumeral internal rotation deficits through a randomized clinical study.

Conditions

Glenohumeral Internal Rotation Deficits

Outcome Measures

Primary Outcomes (1)

• Glenohumeral internal rotation ROM

  The investigators will use the digital inclinometer

  Change from baseline at week 4

Secondary Outcomes (1)

• Maximal glenohumeral external rotation isometric strength

  Change from baseline at week 4

Other Outcomes (3)

• Mean motor unit recruitment (EMG) of the glenohumeral external rotator (infraspinatus) and internal rotators (pectoralis major and latissumus dorsi)

  Change from baseline at week 4

• Pain will be measured using the Numeric Pain Rating Scale

  Change from baseline at week 4

• Subject satisfaction will be measured using the Subject satisfaction Form

  Week 4

Study Arms (2)

Novel Stretching Technique

EXPERIMENTAL

Participants will perform the novel stretch in a supine position. Participants will place a small ball between their knees and squeeze the ball. Participants will be then bridge as high as possible . Participants will then flex their shoulder and elbow to 90°, and actively rotate to the end of ROM. Participants will use the other hand to push to the point of mild discomfort and simultaneously maintain contraction while progressing the stretch.

Procedure: Stretching

Traditional Stretching Technique

ACTIVE COMPARATOR

Participants will perform the modified sleeper stretch in a side-lying position on the side of the throwing shoulder with the throwing shoulder and elbow flexed to 90° . The participants will be instructed to allow the throwing shoulder to naturally fall into internal rotation to the end ROM where resistance will be felt . The participants will be then instructed to use the non-throwing hand to push the throwing shoulder into further internal rotation to the point of mild discomfort by applying pressure at the area of the wrist joint.

Procedure: Stretching

Interventions

Stretching PROCEDURE

The novel stretching technique will be done on a supine position. subjects will be asked bridge as high as possible. After That, Participants will then flex their shoulder and elbow to 90°. Participants will use the other hand to push to the point of mild discomfort and simultaneously maintain contraction while progressing the stretch.

Novel Stretching Technique; Traditional Stretching Technique

Eligibility Criteria

• Age: 18 Years - 45 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Participants must be between the age of 18 and 45.
• Perform overhead sports activities in the past 3 months.
• Participants are required to display ≥ 20° less glenohumeral internal rotation ROM in their dominant shoulder compare to the non- dominate shoulder.
• Participants will be included with or without pain during shoulder activities.

You may not qualify if:

• Will exclude participants who are still recovering from previous surgery of the shoulder and elbow complex in the past 3 months, and currently receiving medical intervention for the shoulder.
