Prevalence of Scapular Dyskinesia in Young Adults with Trapezitis - A Cross-Sectional Study

Background: An abnormal movement of the scapula during shoulder movement is termed as scapular dyskinesia and is an often-forgotten cause of pain and dysfunction. The scapula is a key part of the upper limb kinematic chain and is a vital component of the glenohumeral rhythm. Trapezitis is an inflammatory pain resulting from trapezius muscle. Trapezius is a stabilizer in Scapular dynamics contributing to scapulohumeral rhythm. Weakness or improper activation of Scapular stabilizers can alter Scapular positioning and mechanics. Aim of this study is to find prevalence of Scapular Dyskinesia in young adults with Trapezitis.Methodology: One hundred eighteen young adults of age 18-25 years with Trapezitis selected by convenience sampling participated in this cross sectional study. Participants were allotted to three groups (mild, moderate, severe) according to severity of Trapezitis on the basis of their VAS score. Dynamic scapular Dyskinesis test was used to assess Scapular Dyskinesia. Statistical analysis was done using Microsoft excel version 2010.Results: 118 participants had participated in the study. Out of which 32% participants had mild trapezitis, 37% had moderate trapezitis and 31% had severe trapezitis. In subjects with mild trapezitis 37% of their population had scapular dyskinesia whereas in subjects with moderate trapezitis 57% had scapular dyskinesia and in participants with severe trapezitis, scapular dyskinesia was witnessed in 72% of their population.Conclusion: Present study evidences high prevalence of Scapular Dyskinesia in young adults with Trapezitis.Key words: Scapular Dyskinesia, Trapezitis, Young adults.
