Scapular dyskinesis among patients with shoulder dysfunction – A Cross Sectional Study.
Background: Scapula play key role in closed chain mechanism by being stable base for coordinated muscle activation and functioning as link in kinetic chain. The alteration in scapular resting position and/or dynamic motion due to various causes like presence of bony or soft tissue injury as well as weakness or inflexibility is termed as scapular dyskinesis. So this study was carried out to find out the prevalence of scapular dyskinesis and to study the association of presence of scapular dyskinesis with shoulder pain and disability among patients with shoulder dysfunction.
Procedure: This Cross Sectional study was carried out in 55 patients with unilateral shoulder dysfunction. The outcome measure were Lateral scapular slide test and shoulder pain and Disability index questionnaire.
Result: Scapular dyskinesis was measured in patients with shoulder dysfunction with age 49± 6.92 and duration of symptoms was 2.72 ± 1. 83 months. Prevalence rate of scapular dyskinesis was at 0 degree, 45 degree and 90 degree of shoulder abduction 5.45 % , 12.72% and 18.18 % respectively.
Conclusion : Prevalence of scapular dyskinesis at 0 degree, 45 degree and 90 degree of shoulder abduction 5.45%, 12.72% and 18.18% respectively, shoulder pain and disability was not directly linked with scapular dyskinesis. Which suggest that shoulder pain and disability may not be always associated with shoulder dysfunction, it may be also due to other factors like thoracic vertebral dysfunction, serratus anterior muscle weakness or rhomboid or muscle weakness etc.
