Introduction: Studies suggest that a potential complication that today lacks sufficient study and analysis are the motor patterns disturbances in chronic shoulder pain which occurred after breast cancer treatment. This alteration, maintained permanently, may cause long-term pathologies more committed both locally (impigement subacromial, retractable capsulitis ...) as a more global level by means of the central nervous system. So appears the need to reconsider these issues and propose effective physical therapy programs to solve these dysfunctions.
