The Effect of the Ischemic Compression Technique Applied to Upper Trapezius Muscle on the EMG Activity of the Serratus Anterior and Upper Trapezius during Wall Slide Exercise

Background It is known that a wall slide exercise is required to strengthen the serratus anterior. However, overactivation of the upper trapezius during wall slide exercise reduces serratus anterior muscle activation. There is no study that Ischemic compression affects upper trapezius and serratus anterior muscle activity. Objectives The purpose of this study was to determine the effect of ischemic compression applied to the upper trapezius muscle on the muscle activity of the upper trapezius and serratus anterior during wall slide exercise. Methods A total of 15 healthy male volunteers were recruited for this study. Before and after applying ischemic compression, muscle activity of the upper trapezius and serratus anterior was compared during the wall slide exercise. The electromyographic data of the upper trapezius and serratus anterior was measured using 4D-MT, 2EM. The difference between before and after ischemic compression was analyzed using the paired t-test with p<0.05 as a significant level. Results The upper trapezius muscle activity was significantly decreased (p = 0.014) and serratus anterior muscle activity was significantly increased (p = 0.002) when wall slide exercise after ischemic compression versus before ischemic compression. Conclusions The ischemic compression applied to the upper trapezius will be a useful way to increase the muscle activity of the serratus anterior.
