Objectives: Individuals with generalized joint hypermobility (GJH) have motions beyond the normal range in the shoulder, and less shoulder stability. Scapular dyskinesis is likely to be a consequence of weakness in scapular stabilizer muscle. This study intended to identify the relationship between GJH and scapular dyskinesis in young women.
Materials and Methods: One hundred women (47 hypermobile and 53 non-hypermobile) participated in this case control study. The Beighton score was used to diagnose GJH. Visual scapular dyskinesis test (proposed by Uhl et al) 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, bearing the weight on their hands. Generalized estimating equations were used in order to compare the scapular dyskinesis prevalence during shoulder ﬂexion, abduction and scaption between the females
Results: The prevalence of scapular dyskinesis in the females with GJH was twice more than that in the females with no hypermobility [OR=2.18(95% CI: 1.18-4.03)]. It was also found that there were not any signifcant differences in the prevalence of scapular dyskinesis between shoulder elevation planes (ﬂexion, abduction and scaption) in the females with
Conclusions: Higher prevalence of scapular dyskinesis in the females with GJH may place them at the risk of future shoulder pain and pathology, which should be considered in the evaluation and management of hypermobile individuals.
