Scapular Dyskinesis: A Commonly Seen Mysterious Condition in Asymptomatic Adults – A Narrative Review

Abstract

BACKGROUND: Scapular dyskinesis is defined as visible alterations in scapular positions and motion patterns and is believed to occur as a result of changes in activation of scapular stabilizing muscles. Scapular dyskinesis is not associated with pain and appears to be prevalent in asymptomatic population. The strength deficits or muscular imbalance of scapular muscles lead to disoriented scapular movement, which may contribute to future shoulder injuries. So, this study aims to collect evidence regarding whether scapular dyskinesis is present in asymptomatic adults or not. METHODS: A computer-based literature search was done using various database with keywords. In this review all types of studies were found. Based on predetermined selection criteria, present study included articles between 2012 to 2022, In which 8 out of 46 articles were fitted in the study on the basis of inclusion criteria. RESULT: Results of all the studies reviewed, concluded that scapular dyskinesis is commonly seen in asymptomatic adults. CONCLUSION: Strong evidence exists to show the presence of scapular dyskinesis in asymptomatic adults. Some study depicts the idea that asymptomatic individuals with scapular dyskinesis have strength deficits and require intervention to prevent future shoulder injuries.
