Effect of the Modified Sleeper-Stretch on the Elasticity of the Posterior and Posteroinferior Glenohumeral Capsule

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.
