sEmg Biofeedback Training in Individuals With Subacromial Pain Syndrome

Objective: To investigate the effects of EMG biofeedback training on the pattern of scapular muscle activation and kinematics in subjects with subacromial pain syndrome. Methods: This is a randomized controlled trial, which will be composed of 40 volunteers of both genders, aged between 30 and 60 years. All volunteers will undergo pre-assessment (IA): pain sensation, pain and function, shoulder range of motion, muscle strength, electromyographic activity and kinematics of the shoulder complex. After the initial evaluation, the volunteers will be randomly divided into two groups for the intervention: exercises group (GE - conventional exercises with elastic band) and Biofeedback group (BG - Biofeedback training). The intervention protocol will last eight weeks. After four weeks, the second assessment (SA), similar to IA, will be performed and the global change perception questionnaire will be added. At the end of the intervention protocol, the third evaluation (TA), similar to SA, will be performed. A follow-up will be performed 4 weeks after the end of the intervention protocol, with the assessment being equal to TA. Statistical Analysis will be performed through Statistical Package for Social Sciences (SPSS) software version 20.0 for Windows, following the principles of intention-to-treat analysis. The descriptive analysis will use the mean as a measure of central tendency and the standard deviation as a measure of dispersion. A mixed model ANOVA will be performed for intra and intergroup comparisons.
