There are several factors that could decrease the subacromial space and cause impingement of the soft tissues that are grouped and defined as impingement syndrome. Subjects who have the syndrome have an altered pattern on scapular kinematics characterized by a decrease in upward rotation, posterior tilt, increasing medial rotation, and changes in the pattern of muscle recruitment, with greater activation of descending trapezius fibers and less activation of ascending and transverse fibers and of the serratus anterior. The use of biofeedback electromyographic (EMG) already proved useful to stimulate muscles contraction, which has lower activation through stimulation provided by the program. The aim of this study is to determine the acute effect training with electromyographic biofeedback in subjects with impingement syndrome and observe the kinematics after an exercise protocol that target a greater activation of the ascending and transverse portions of the trapezius and serratus anterior. We will select twenty-five subjects diagnosed with the syndrome who will undergo three specific exercises for muscle activation, in three series of three replicates. The three-dimensional analysis of the scapula will be held in the scapular, sagittal and frontal plane with the electromagnetic system 3SPACE ® Liberty ® (Polhemus Inc.). The subject will perform five lifting movements of the arms on each plane during four seconds each. The data will help to analyze if the use of EMG biofeedback can change the scapular positioning to what is considered more functional, after the exercises (AU)
