Objectives: Individuals with Generalized joint hyper mobility (GJH) have more range of motion in shoulder and less shoulder stability. Scapular dyskinesisis likely to be a consequence of stabilizing scapular muscle weakness .This study intends to identify the relationship between GJH and scapular dyskinesis in young women.
Materials and methods: One hundred women (n=47 hyper mobile and n=53 non-hyper mobile) participated in the studythrough a case control design. The Beighton scale was used to diagnose GJH. Visual Scapular dyskinesis test (Uhl method) was used for the evaluation of scapular dyskinesis. Scapular winging and/or dysrhythmia is observed during a set of bilateral, active, shoulder flexion, abduction and scaption (40° anterior to the frontal plane) for 5 times while having the thumbs pointed up. These movements were performed with a weight held in theirs hands. Generalized estimating equations were used in order to compare the scapular dyskinesis prevalence during shoulder flexion, abduction and scaption between females with and without GJH.
Results: The result showing the prevalence of scapular dyskinesis in females with GJH was twice more than females with no hyper mobility [OR=2.18(95% CI: 1.18-4.03)]. Also, it was found that there weren"t any significant differences in prevalence of scapular dyskinesis between shoulder elevation planes (flexion, abduction and scaption) in females with and without GJH(p>0.05).
Conclusion: The higher prevalence of scapular dyskinesis in females with GJH may place them at the risk of future shoulder pain and pathology, which should be considered in evaluation and management of hyper mobile individuals.
