How to Relieve Thoracic Outlet Syndrome

Updated: Nov 19, 2022

Thoracic outlet syndrome (TOS) is a group of disorders that occur when blood v

essels or nerves in the space between your collarbone and your first rib (thoracic outlet) are compressed. This can cause pain or aches in your neck, shoulder, arm or hand, Numbness or tingling in your arm or fingers.

Historically, TOS presents with symptom onset between the ages of 20–50 years old and is more prevalent in women

Subtype of Thoracic outlet syndrome

A systematic review by Sanders et al. described symptom distribution in neurogenic TOS to include upper extremity paresthesia (98%), neck pain (88%), trapezius pain (92%), shoulder and/or arm pain (88%), supraclavicular pain (76%), chest pain (72%), occipital headache (76%), and paresthesias in all five fingers (58%), the fourth and fifth fingers only (26%), or the first, second, and third fingers

  • Pain in the shoulder and neck

  • Ache in the arm or hand

  • Altered sensation in the arm

  • Numbness or tingling in any area from neck to arm, hands or fingers

  • Muscle weakness in the arm

  • Weakness with grip

TOS symptoms are similar to the symptoms of many other conditions. A herniated disc in the neck, carpal tunnel syndrome in the hand, and bursitis of the shoulder can all cause symptoms very much like those of TOS.


What are the causes of thoracic outlet syndrome

  • Poor Posture

Poor Posture Become the main cause of thoracic outlet syndrome

Slouching and drooping shoulders or forward head position can cause increased tension in the side neck muscles and stretching of the nerves, leading to compression in the thoracic outlet. Forward head posture, rounded shoulders, and a rounded thoracic back can decrease the space by which the nerves and blood vessels can travel. The poor body alignment of slouching can compress the nerves and arteries near the thoracic outlet. Being overweight can cause problems with posture

  • Trauma

Traumatic events e.g. car accident causing injury, bony or soft tissue changes to the thoracic area.

  • Repetitive Activities

Those involving repetitive overhead movements, prolonged typing on a computer, and poor lifting techniques can increase strain on tissues in the neck and shoulder to cause compression of the vascular and neural structures in the thoracic outlet.

  • Anatomical Defects

Extra rib from the neck at birth (cervical rib) narrowing the thoracic outlet and increasing the susceptibility of compression. or an abnormally tight fibrous band that connects the spine to the rib

  • Muscle Enlargement

Increased muscle bulk at the neck and shoulders from weightlifting can increase susceptibility to compression of the thoracic outlet.


What can you do about it


If an individual is diagnosed with arterial or venous TOS, surgery is typically the only option due to the severity of the injury.


Surgical intervention for nTOS syndrome is reserved for patients who have failed conservative management. Conservative treatment including physical therapy need be trailed for at least 4–6 months prior to consideration of surgical intervention


a 4-6 months long physical therapy program will include stretches to improve flexibility, massage therapy to reduce pain, exercises to strengthen the region, and education on strategies to improve the health of the nerves and arteries located in the thoracic outlet.


Strengthening exercises alone will not alter the pathophysiology of TOS; a combination of strengthening, stretching, and postural adjustments must all be incorporated for improvements to be observed.


A home exercise program is essential to the treatment of TOS. This is true even if the cause of your TOS is an abnormality in the bones and muscles. You must consistently do your exercises to get the most benefit.

Posture correction and education on self-management are important as well to promote restoration of function. Patients with Thoracic Outlet Syndrome need to regularly be conscious of their posture.



Adjust the chair height so your feet are flat on the floor and your knees are in line (or slightly lower) with your hips. Sit up straight and keep your hips far back in the chair. The back of the chair should be somewhat reclined at a 100- to 110-degree angle.
