Correlation among scapular asymmetry, neck pain, and neck disability index (NDI) in young women with slight neck pain

Abstract

[Purpose] This study aimed to investigate the correlations among scapular asymmetry, neck pain, and neck disability index in women in their 20s with slight neck pain. [Subjects and Methods] A total of 60 female students at U university in Gyeongsangbuk-do, South Korea, participated in this study. The lateral scapular slide test, which measures the distance between the thorax and scapula, was used to analyze the scapular asymmetry. The lateral scapular slide test was performed in three positions. The visual analogue scale and neck disability index were used to measure neck pain. [Results] In the lateral scapular slide test in position 3 (shoulder abduction at 90 degrees), the scapular left-right asymmetry and VAS showed a moderate positive linear relationship, with r=0.344. The VAS and NDI showed a moderate positive linear relationship, with r = 0.632. [Conclusion] Scapular asymmetry indicates imbalance of surrounding muscles of the scapula and is related to neck pain based on the results of measuring the distance from the thorax to the scapula.
