Smooth motion

In addition to the motion at the glenohumeral joint the upper end of the humerus biceps tendon and rotator cuff must glide smoothly inside a sleeve consisting of the acromion deltoid coracoid coracoacromial ligament and the muscles originating from the coracoid. This motion is described as motion at the humeroscapular motion interface.

Excursions of up to 4 cm take place at this nonarticular interface.

Shoulders can lose their normal smoothness of motion for a wide variety of reasons. In many situations the roughness is related to tightness of the soft tissues around the joint to abnormal posture or to shoulder weakness.
