Background The scapular assistance test (SAT) is used to identify the scapular abnormal movement that is prominent in scapular dyskinesis. SAT is expected to affect the muscle activity of the serratus anterior (SA) and lower trapezius (LT) muscles by assisting the upward rotation and posterior tilt of the scapula. Objectives To compare the differences in muscle activity of the upper trapezius (UT), SA, and LT, in subjects with scapular dyskinesis according to the SAT. Also, to compare the muscle activity of the anterior deltoid (AD) and middle deltoid (MD) in subjects with scapular dyskinesis. Methods A total of 20 male subjects with scapular dyskinesis participated and performed the arm raising under the SAT and non-SAT conditions. In the SAT condition, the examiner assisted the subjects with upward rotation and posterior tilt of the scapula while they raised their arms. UT, SA, and LT muscle activity and AD and MD muscle activity were measured simultaneously and compared between SAT and non-SAT conditions. Results Muscle activity of the SA (p < 0.001) and LT (p = 0.009) was significantly higher in the SAT condition compared to the non-SAT condition. The muscle activity of the AD was significantly lower in the SAT condition compared to the non-SAT condition (p < 0.001). However, there was no significant difference in the muscle activity of the UT and MD between the SAT and non-SAT conditions (p > 0.05). Conclusions The changes in muscle activity of the SA and LT according to SAT could be presented as one of the theoretical bases explaining the clinical usefulness of SAT for examining scapular dyskinesis.
