Joint capsules and ligaments in people with increased mobility are loose, which can lead to instability in the entire scapula-brachial complex. The cause of this condition can be congenital (immobility) or acquired factors related to the performance of a repetitive movement pattern (for example in gymnasts).
The muscles stabilizing the head of the humerus and the scapula are disturbed as a result of posture defects, training or occupation overloads, which in turn leads to narrowing of the articular spaces and increased friction.
Since the shoulder joint is part of the shallow acetabulum hanging joints, its stabilization strongly depends on the surrounding structures : the joint capsule, ligaments and muscles. In a situation of immobilization, all these structures contract, which can lead to frozen shoulder syndrome.
Pain in the shoulder area requires detailed differential diagnosis. The selected diagnostic criteria must first confirm that the sources of pain are the structures of the shoulder girdle. The causes of the conditions can also be projected from other adjacent body regions, for example the neck, internal organs (for example the heart), existing neoplasms and even as a result of distant fascial dysfunctions currently under study. First of all, it is advisable to conduct a thorough and thorough physical and subjective examination.
