Comparison of Scapular Position in Dominant and Non Dominant Sides of Healthy Adult\'s Females

Abstract

Objective: The goal of this research was to compare normal scapular position (protraction, rotation) and lateral scapular test on arm elevation between dominant and non dominant sides. Materials & Methods: Thirty healthy females (age=21.9 years, weight=53.37 kg, height =160.60 cm) were chosen by non probability sampling and participated in this cross – sectional and comparative study. Scapular rest positions (protraction and Rotation) were measured by use of Diveta method and scapular asymmetry was assessed by using lateral scapular slide test (Kibler test). Validity and reliability of measurement methods were assessed by determination of ICC and SEM and data were analyzed by use of paired T test. Results: The difference between dominant and non dominant scapular protraction and rotation was not found to be statistically significant (P=0.61, P=0.57).The dominant scapula was found to be more lateral in 2nd and 3rd Kibler tests positions than non dominant scapula (P<0.001). There was no significant difference in lateral scapular slide test between dominant and non dominant sides when the arms were by the side of body (P=0.66). Conclusion: Scapular rest position is influenced by hand dominance
