Summary

The purpose of this randomized controlled trial is to investigate the additional effects of upper extremity plyometric training versus strength training alone in recreational overhead athletes with shoulder instability. The investigators hypothesis that compared to strengthening training alone, plyometric training combined with strengthening training will significantly improve shoulder isokinetic strength, proprioception, scapular kinematics, symptoms of shoulder instability, and shoulder function.

Conditions

  • Glenohumeral Subluxation
  • Shoulder Subluxation
  • Shoulder Instability Subluxation Bilateral

Interventions

PROCEDURE

Plyometric and strengthening exercises

Each session includes 2 upper-extremity plyometric exercises in bodyweight or with weight ball for 15-20 minutes and 4-5 strengthening exercises with band, dumbbell or barbell for 30-35 minutes. The difficulty of the movement protocol will increase weekly. They will be trained 2 times per week for 6 weeks with an average duration of 50 min per session.

PROCEDURE

Strengthening exercise

Each session includes 5 upper-extremity strengthening exercises with band, dumbbell or barbell for 50 minutes. The difficulty of the movement protocol will increase weekly. They will be trained 2 times per week for 6 weeks with an average duration of 50 min per session.
