Influence of an Anterior Latarjet-type Abutment Operation on Scapular Dyskinesia and the Muscular Stabilization Mechanisms of the Scapula (DyScapLat)

Not Applicable

• Conditions: Scapular Dyskinesis; Latarjet
• Interventions: Procedure: Latarjet method; Other: Different arms exercices

• Registration Number: NCT05131126
• Lead Sponsor: Ramsay Générale de Santé

Brief Summary

The aim of this study is to assess the influence of anterior abutment surgery using the Latarjet method on the kinematics of the scapula. The sub-objectives will be to show that Latarjet-type surgery does not lead to scapular dyskinesia and modification of muscle activity compared to a control group that has not undergone an operation.

Primary Outcome Measures

Name	Time	Method
Difference in position of the scapula (tilt, rotation and bell) between the pre and post-test measured in the control group	4 months	For electromyographic analysis, the signals will be filtered, smoothed and normalized to obtain a percentage of activation relative to that measured during submaximal voluntary contractions.
