- Abstract
Purpose: The purpose of this study was to evaluate the upper trapezius (UT) to middle trapezius (MT) muscle activation ratio during scapular retraction exercises at different shoulder abduction degrees in asymptomatic individuals. Methods: Twenty asymptomatic individuals (10 males, 10 females) were participated in this study (mean±SD age, 22.9±2.8 years). A surface electromyography system (TELEmyo DTS; Noraxon USA, Inc, Scottsdale, AZ) was used to measure the activation levels of the UT and MT muscles during scapula retraction exercises. For the scapular retraction exercise, participants were instructed to perform of resisted scapula retraction with an elastic band at each shoulder abduction angle (0°, 45°, 60° and 90°). A repeated measures of ANOVA was used to determine whether UT:MT ratio differed among scapula retraction exercises. Results: There was significant exercise effect on UT: MT ratio (F(3,57) =7.53, p<0.001). UT: MT ratio was lower at 0° scapular retraction exercise when compared to 45° (p=0.02), 60° (p=0.03) and 90° (p=0.003) scapular retraction exercises. There were no difference between 45° and 60° (p=0.28), and 60° and 90° (p=1.00) scapular retraction exercises in terms of UT:MT ratios. Conclusion: Compared to 45° and 60° of shoulder abduction, UT:MT ratio was greater at 60° and 90° of shoulder abduction. Since UT:MT ratio was lower than 1, scapula retraction exercise at or under 90° of shoulder abduction might be suggested for the individuals with shoulder problems.
