Abstract
ABSTRACTObjective:To analyze the position of the scapula and its influence on shoulder pain. Methods:In this study, 30 sedentary young adults of both genders, aged 20-35 years were evaluated. The sample was divided into two groups with the same number of subjects, one group with shoulder pain and the other pain free. The analysis of the positioning of the scapula in six angles of shoulder abduction was taken 0º, 30º, 60º, 90º, 120º and 180º. Results:Comparison the left and right scapular movements in males of the pain group, there was a significant difference at 30º (p = 0.018) and 120º (p = 0.04). Comparing the right and left shoulders in the pain group, there was a significant difference at 0º (p = 0.03). Conclusion:This study concludes that changing the positioning of the scapula affects shoulder pain in sedentary young adult males at certain specific positions. Level of Evidence III, Study of non consecutive patients; without consistently applied reference ''gold'' standard.
Highlights
Shoulder diseases have aroused much interest among medical professionals
Scapular dyskinesia is considered any change occurring in the scapulothoracic pace, which causes a change in the position, scapular movements or normal mobility of the scapula relative to the thorax.[8]
The same comparison made in female subjects found no statistically significant difference, and for the male subjects, the right scapula showed greater lateral rotation as compared to the left scapula at 30° and 120°. (Table 2) Comparing the right and left movements in the pain group, we found a statistically significant difference at 0° (p = 0.03), what lead us to conclude that the position of the right scapula is more lateralized as compared to the left scapula for the resting shoulder
Summary
Shoulder diseases have aroused much interest among medical professionals This is mainly because the shoulder is responsible for implementing most of the movement and positioning of the upper limb.[1] The shoulder is considered fairly stable due to its joint anatomy, especially in the glenohumeral joint, which has great mobility and low stability, making it necessary for the synchronic and constant harmony between all the structures that maintain the normal biomechanics.
