What are the symptoms and treatment methods for shoulder periarthritis?

Periarthritis of the shoulder, also known as adhesive capsulitis or frozen shoulder, is a common shoulder condition primarily affecting individuals over the age of 40, especially women. It is characterized by shoulder joint pain and limited range of motion, with symptoms often worsening at night, significantly impacting the patient's quality of life.

Common symptoms of periarthritis of the shoulder include:

1. Pain: Shoulder pain is the most common symptom, especially at night, which may interfere with sleep.

2. Movement impairment: Significant movement limitations occur in the shoulder joint, including difficulty with elevation, extension, abduction, and internal rotation of the shoulder.

3. Stiffness: Muscles and surrounding tissues of the shoulder become stiff, leading to restricted movement.

Common treatment options for periarthritis of the shoulder are as follows:

1. Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and diclofenac sodium can be taken orally. Local injections at painful sites can also provide significant pain relief.

2. Physical therapy: Treatments such as heat application, massage, manipulation, and electrotherapy can improve local blood circulation and promote the absorption of inflammatory substances.

3. Surgical treatment: In rare cases where conservative treatments fail, surgery such as arthroscopic shoulder surgery may be considered to release the adhesions.

4. Regular exercise: Maintain flexibility and strength of the shoulder muscles and avoid prolonged immobility.

5. Proper posture: Avoid maintaining poor posture for extended periods, such as looking down at a phone or computer screen for long periods.
