Parsonage Aldren Turner Syndrome (PATS), also known as Brachial Neuritis or Parsonage-Turner Syndrome, is a rare neurological disorder characterized by sudden, severe shoulder and arm pain, followed by muscle weakness and atrophy in the affected area. This condition primarily affects the upper extremities, specifically the shoulder, arm, and sometimes the neck.
The exact cause of PATS is still unknown, but it is believed to be related to an autoimmune response triggered by a viral or bacterial infection, vaccination, or physical trauma. It is most commonly seen in adults, although it can occur in children as well.
Symptoms of Parsonage Aldren Turner Syndrome typically begin with acute, intense pain in the shoulder or arm, often described as a burning or shooting sensation. This pain can become severe and might last for a few days to several weeks. Following the pain, weakness and atrophy of muscles in the affected area may develop, leading to difficulty in performing daily activities such as lifting objects, reaching, or gripping.
Diagnosis of PATS is mainly clinical, based on a thorough medical history and physical examination. Other possible causes of shoulder pain and weakness must be ruled out through imaging tests, blood work, and electromyography (EMG).
Treatment for Parsonage Aldren Turner Syndrome focuses on managing pain and promoting rehabilitation. Non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids may be prescribed to alleviate pain and reduce inflammation. Physical therapy and specific exercises can help strengthen the affected muscles and improve range of motion. Recovery from PATS can vary widely, with some individuals experiencing complete resolution of symptoms while others may have residual weakness or chronic pain.
