What might limit the range of motion (ROM) in periarthritis humeroscapularis?

In the context of periarthritis humeroscapularis, also known as frozen shoulder, degenerative changes at tendon insertions can significantly limit the range of motion. This condition is characterized by inflammation and stiffness in the shoulder joint, which is often accompanied by pain. The tendons at the shoulder, particularly the rotator cuff tendons, can undergo degenerative changes and lead to a reduction in their elasticity and function. As these changes occur, they can restrict the movement of the shoulder joint, resulting in a decreased range of motion.

Additionally, as joints and surrounding tissues become stiff due to inflammation or degeneration, movement becomes painful and difficult, further contributing to the limitation in range of motion. This cycle of pain and restricted movement is indicative of the pathological changes occurring in periarthritis humeroscapularis, emphasizing how degenerative changes directly impair mobility in the shoulder region. Understanding this connection helps clinicians address the underlying issues effectively during treatment.
