Thoracic Outlet Syndrome: A Practical Physiotherapy Overview

The thoracic outlet is a passage between the neck, collarbone and first rib. Nerves and blood vessels travel through it toward the arm. When this space or its surrounding muscles are irritated, symptoms may include arm numbness and tingling, hand numbness, aching, fatigue or altered colour and temperature. The presentation depends on whether nerves or vessels are involved.

A rehabilitation assessment considers breathing habits, shoulder-blade control, neck movement, work demands and repeated overhead activity. Similar symptoms can arise from the neck, shoulder or wrist, so a clear assessment matters.

A physiotherapist may begin with comfortable breathing, gentle neck and upper-back movement, shoulder-blade control and a gradual return to lifting. The programme should be adjusted if tingling lasts after exercise or strength declines. Postural correction therapy can help you practise less compressed positions during desk work, driving and sleep. Progress is usually guided by response rather than a fixed routine.

Seek urgent care if the arm becomes suddenly swollen, cold, pale or blue, or if you develop severe weakness, chest pain or breathlessness. Arrange prompt medical review for worsening grip, spreading numbness or symptoms that are no longer linked to activity.

Which form of thoracic outlet syndrome is suspected? Which exercises fit my findings? How should I modify overhead work, carrying and sleep positions?
