The Cross Sectional Area Assessment Of the Supraspinatus Muscle On the Dominant Versus Non Dominant Shoulder By Ultrasonography (original) (raw)

Abstract

Introduction: The rotator cuff muscles have been showed to be the substantial dynamic stabilizers of the glenohumeral joint in multiple shoulder positions. The supraspinatus provides glenohumeral compression, abduction and generates a small external rotation (Reinold et al. 2009). The architectural characteristics of the supraspinatus usually involve in measuring parameters as thickness, width and cross sectional area (CSA) as important factors for the functionality during dynamic and static movements (Whittaker, et al. 2011; Han, et al. 2012). Objectives: The objective of this study was to evaluate the CSA of the supraspinatus muscle on the dominant and non- dominant shoulders in amateur tennis players using brightness mode ultrasonography, as prognostic factors to improve insights for physiotherapists and orthopaedic surgeons. Methods: Ultrasonography images from the supraspinatus CSA were recorded in 20 participants, 23-27 years of age, who were involved unprofessionally in tenni...
