How Does Periarthritis of the Shoulder Develop?

Patients with periarthritis of the shoulder (frozen shoulder) may experience shoulder pain or difficulty combing their hair. As the causes of periarthritis of the shoulder are varied, how does this condition develop?

How Does Periarthritis of the Shoulder Develop?

Multiple factors contribute to the development of periarthritis of the shoulder, including aging, excessive physical strain, environmental triggers (e.g., cold and damp conditions), and trauma. This condition most commonly affects individuals around age 50, with a higher incidence among women. The underlying mechanism involves age-related degeneration of muscles and soft tissues surrounding the shoulder joint. The shoulder joint is one of the most frequently used and highly mobile joints in the human body. Excessive or repetitive shoulder movement can damage the surrounding musculoskeletal structures—particularly common among manual laborers. Similarly, athletes engaged in sports such as swimming and badminton are also at increased risk. In addition to overuse, prolonged maintenance of a fixed shoulder position may lead to atrophy and adhesions of periarticular tissues, potentially progressing to periarthritis of the shoulder.

Cold exposure may trigger or exacerbate periarthritis of the shoulder. Prolonged residence in cold, humid environments similarly increases susceptibility. Shoulder trauma—including fractures of the scapula or clavicle—often necessitates prolonged immobilization during treatment. Reduced shoulder mobility over time predisposes patients to periarthritis of the shoulder.

In daily life, ensure adequate warmth for the shoulders. Individuals who maintain static postures for extended periods should regularly perform shoulder mobility exercises. Older adults should proactively adopt preventive measures against periarthritis of the shoulder. We hope this article has been helpful. Wishing you a joyful life and optimal health!
