ABC Orthotic & Prosthetic Practice Exam

Adhesive capsulitis, commonly known as frozen shoulder, often arises from situations where the shoulder joint experiences a lack of movement or has been immobilized for an extended period. Post-surgical immobilization is particularly significant because after surgery, it is common for patients to restrict their shoulder movements to allow healing. This immobilization can lead to the thickening and tightening of the shoulder capsule, contributing directly to adhesive capsulitis.

This condition results when the connective tissues surrounding the shoulder joint become inflamed and stiff, making it increasingly difficult to move the shoulder. The immobilization period sets the stage for this stiffening process, which is why it's a key factor in the development of adhesive capsulitis.

In contrast, while overuse injuries, repetitive overhead activities, and tight ligaments may contribute to shoulder problems, they do not directly cause the same degree of immobilization and resultant capsule thickening that is characteristic of adhesive capsulitis. Therefore, these factors are less likely to be the primary cause of this specific condition compared to post-surgical immobilization.
