Clinical Trial Summary

The goal of this clinical trial is to evaluate the effects of Blood Flow Restriction (BFR) training on post-surgery rehabilitation following the Latarjet procedure in athletes aged 18-35. The main questions it aims to answer are: Does BFR training improve scapular belt muscle strength post-surgery? Does BFR training enhance shoulder function during rehabilitation? Researchers will compare three groups: BFR Group with 50% AOP [arterial occlusion pressure] compression BFR Placebo Group with 10% AOP compression Control Group Participants will: Perform the same four strengthening exercises twice a week Complete 16 semi-autonomous strength training sessions over 8 weeks Undergo isokinetic and isometric strength tests, shoulder mobility assessments, and complete self-assessment questionnaires.

Intervention

Device:
Blood flow restriction (50% AOP compression) in the rehabilitation phase after Latarjet surgery for chronic shoulder instability
Participants undergoing shoulder instability surgery (Latarjet procedure) by a single surgeon will receive standard physiotherapy (2 sessions per week) before being randomized into 3 groups at their 6th postoperative week check-up: Group 1) BFR Group with 50% AOP compression Group 1 will perform a 30-minute strengthening session twice weekly during postoperative weeks 7 to 14. They will do 4 exercises, completing 4 sets with 30-second rest intervals and 1 minute between exercises, following 30-15-15-15 at 40% 1RM (repetition maximum) Exercise : External rotation with pulley/band Internal rotation with pulley/band Frontal elevation with hyperpronation Diagonal abduction-external rotation with pulley/band BFR training will use the MadUp© system, placing the band proximally on the operated arm, with a central unit continuously monitoring and calibrating arm pressure.
