Introduction: Scapular position and shoulder alignment is very important in a good physical condition and injury prevention. Muscles of the shoulder girdle and scapula are common connection and abnormality or asymmetries in one of them, associated with another dysfunction. The purpose of this study was the study of upper quarter functional & scapular position in people With uneven shoulder.
Methodology: In the present study, 26 students selected with uneven shoulder at average of 24.5±2.31 years. Upper quarter balance test (YBT-UQ) was used for measuring functional stability in close kinematic chain of both dominant and non-dominant shoulder. Scapular protraction and rotation was measured according to Diveta method. After checking the normal distribution of the results with Shapiro-wilk, paired sample t-test were used in SPSS to analyze the data (version 16).
Results: The mean of difference shoulders was 2.07±1.16 degree. No significant difference was observed between functional stability of both Shoulders But the mark was more at upward shoulder side. No significant difference was observed between scapular protraction and scapular rotation of both Shoulders, while upward scapular protraction and scapular rotation were high more than downward shoulder.
Discussion: The mean of difference shoulders was 2.07±1.16 degree. No significant difference was observed between functional stability of both Shoulders But the mark was more at upward shoulder side. Due to slight differences in the level of the shoulders, seams the important structures such as muscles is less impressed in function in this study. Also seems that in this Functional test other factors such as core stability and lower extremity muscle strength are effective that has not been studied in this study.
