Shoulders are one of the vital joints of the human body, allowing the arms to perform a variety of tasks efficiently like lifting, twisting, pushing, pulling and many more. Even the smallest impediment can hinder your movements and stop you from performing many of those essential daily tasks.
The collarbone (clavicle), shoulder blade (scapula) and the upper arm bone (humerus) are held together by the rotator cuff to make the shoulder, kept in place by a combination of four muscles and their tendons. These muscles help with the movements your shoulder performs.
