Thoracic Outlet Syndrome

What causes it?

In general, the condition is not well understood. Different reasons are proposed for the development of T.O.S; overdeveloped ligaments in the area, the presence of an extra rib in the neck, and poor posture leading to shortened muscles around the neck and shoulder. A history of surgery to the sternum (chest bone) may also increase the risk of T.O.S.

What are the symptoms?

The affected person will usually report feelings of pain and heaviness in the arm. Depending on which structure is compressed, additional symptoms in the arm could also include pins and needles, temperature changes, or swelling in the hand. Maximum symptoms will usually occur when the arm is in the overhead position.

How is it diagnosed?

Diagnosis of T.O.S is made by your physiotherapist, based on your symptoms and response to specific tests of your neck and arm.

How is it managed?

The vast majority of T.O.S improves with physiotherapy management comprising of manual therapy, stretches, postural correction, and strengthening exercises at the neck and shoulder.
