Due to its great mobility, the shoulder joint is among the most unstable joints of the human body. Stabilization of the shoulder is provided by a muscle-tendon structure called the rotator cuff. The rotator cuff consist of the supraspinatus, infraspinatus, teres minor and subskapularis muscles. People who use their hands a lot, especially in the overhead position, are more likely to develop damage. Shoulder impingement syndrome is a condition in which there is a narrowing of the subacromical space, which causes damage to the tendons and other strucutres located in the narrowed subacromical space. The tendons of the supraspinatus and infraspinatus muscles are among the structures that are most often affected during shoulder impingement syndrome. Repeated movements above the head, especially abduction and elevation, create a prerequisite for the narrowing of the space between the acromion and the big tubercle, which can lead to a pathological condition in the area of the shoulder joint. Shoulder impingement syndrome is characterized by pain and reduced range of motion. The most intense pain occurs during the abduction movement between 70° and 120°. The outstretched position of the arm and sleeping on the affected side worsens the condition, and as a result, weakness and stiffness of the segment may occur. Specific tests are considered as the primary method for the assessment of impingement syndrome, which will determine with certainty the type and characteristics of the damage itself. The treatment of impingement syndrome in the early stages is based on analgesic methods of rehabilitation, and later the primary method is considered to be therapeutic exercises, or in other words strengthening and stretching exercises that will restore stability and mobility to the joint and allow the person to return to normal functional abilities.
