Reproducibility of Functional Shoulder Tests for the Return to Sport of Patients Operated on Previous Shoulder Instability

Not Applicable

• Conditions: Shoulder Injuries; Latarjet
• Interventions: Other: Functional tests

• Registration Number: NCT05084703
• Lead Sponsor: Ramsay Générale de Santé

Brief Summary

The aim of this study is to assess whether the indicators outcome of these tests discriminate between different populations. In particular to compare populations with shoulders without any history of injury with a population that had undergone a reduction in glenohumeral instability by the Latarjet technique.

Detailed Description

The different objectives of this study are :

* To assess the intra- and intersessional reproducibility of functional shoulder tests

* To evaluate the influence of an anterior front stop using the Latarjet method on the functional profile of the shoulder compared to a healthy population.
