- Brief Summary
The goal of this quasi-experimental study is to determine the effect of the self-administered Modified Sleeper-Stretch on the elasticity of the posterior and posteroinferior glenohumeral capsule in adult individuals of both genders who either have clinical history of non-specific shoulder pain in a single shoulder or have no history of shoulder pain at all, being the assessment made by means of shear wave elastography. The main hypothesis it aims to confirm is:
• A soft tissue stretching program, using the Modified Sleeper-Stretch, aimed at general adult population with history of nonspecific shoulder pain that has occurred with glenohumeral internal rotation deficit improves the elasticity of the posterior and posteroinferior glenohumeral capsules, showing no significant effect on general adult population without history of shoulder pain.
Researchers will compare the effect of the Modified Sleeper-Stretch in the elasticity of the posterior and posteroinferior glenohumeral capsule in individuals with history of shoulder pain applying the technique on the affected shoulder and comparing with the healthy shoulder. In healthy individuals the intervention will be made on a randomly assigned shoulder and the effect will be compared to the non-interventional shoulder. Finally, a comparison between groups will be made considering only the intervention shoulder to see if there are differences in the effect amongst healthy and affected individuals.
Participants will be asked to follow a self-administered Modified Sleeper-Stretch program consisting of the execution of the stretch three times, for thirty seconds each time, with thirty seconds between stretches, daily, for twenty-eight days.
- Detailed Description
Non-specific shoulder pain is the third most frequent among musculoskeletal pains. It causes functional limitation that can lead to capsular stiffness and restriction of movement. Interventions aimed at reducing posterior capsule stiffness may improve the symptoms of painful shoulder. Modified Sleeper-Stretch is credited with the ability to decrease posterior shoulder stiffness. Shear-wave elastography is an imaging technique capable of quantifying the stiffness of the posterior capsule of the shoulder.
The objective of this study is to determine the effect of a stretching program using Modified Sleeper-Stretch on the elasticity of the posterior and posteroinferior capsule of the glenohumeral joint in adult population with and without a history of non-specific shoulder pain, using shear-wave elastography.
A quasi-experimental pre-post study will be conducted over two experimental groups of 32 subjects each. The intervention will involve following a self-stretching program of the posterior region of the shoulder using modified sleeper-stretch for 28 days. The study subjects will be adult individuals with a history of non-specific shoulder pain in the first group and no history of shoulder pain in the second. The first group will follow the program on the affected shoulder, the second on a randomly assigned shoulder. The elasticity of the posterior and posteroinferior glenohumeral capsule will be measured by shear-wave elastography in both shoulders at the beginning of the intervention, at its completion and four weeks after the end of the intervention.

Group Intervention Description Shoulder pain history Modified Sleeper-Stretch Execution of the Modified Sleeper-Stretch three times, for thirty seconds each time, with thirty seconds between stretches, daily, for twenty-eight days. The stretch will be applied on the shoulder with history of shoulder pain. No history of shoulder pain Modified Sleeper-Stretch Execution of the Modified Sleeper-Stretch three times, for thirty seconds each time, with thirty seconds between stretches, daily, for twenty-eight days. The stretch will be applied on a shoulder randomly assigned.
