  • Objective: Verbal and tactile feedback during rehabilitation exercises for scapular dyskinesis can potentially improve muscle activation. However, it is unclear which method of feedback provides the greatest increase in muscle activation. The purpose of this study is to evaluate the effects of verbal and tactile cuing on scapular stabilizing EMG amplitude in healthy young adults during common shoulder rehabilitation exercises. Methods: 30 physically active participants volunteered for this study (age=20.23±1.25 years, height=1.71±.073m, mass=70.11±15.14kg). Electromyography of the scapular stabilizing muscles (serratus anterior, upper/middle/lower trapezii and anterior/posterior deltoid) was recorded. Results: There was a significant effect for feedback condition for the middle trapezius [F1,2=4.102, p=0.002] and serratus anterior [F1,2 = 3.492, p=0.037] during Y's, the middle trapezius [F1,2=5.893, p =0.005] during W's, and the upper trapezius [F1,2=3.854, p=0.027] and middle trapezius [F1,2=4.268, p=0.019] during T's. Conclusion: Results indicate that adding tactile feedback to verbal feedback did not increase muscle activation compared to verbal feedback alone.
