How do you test for thoracic outlet syndrome?

Computed tomography (CT) scan and magnetic resonance imaging (MRI) of the chest. CT scan or MRI of the spine to rule out cervical spine impingement (pressure), which can mimic neurogenic thoracic outlet syndrome. Magnetic resonance imaging with angiography (MRA) to view blood vessels.

What is thoracic outlet syndrome imaging?

Imaging with ultrasound, contrast-enhanced CT, MRI or conventional angiography is useful for detecting vascular thoracic outlet syndrome (e.g. arterial and/or venous compression). Imaging is performed with the patient’s arms both in the raised (abducted) and neutral (adducted) positions for comparison.

What is Wright’s test?

Wright’s test involves bringing the client’s upper extremity back into abduction and extension while the therapist palpates the strength of the radial pulse (Fig. 13A).

How do you test for neurogenic TOS?

Neurogenic TOS is diagnosed by using provocative maneuvers to elicit (or provoke) symptoms. These maneuvers put the neck and arms in certain positions which put stress on the nerves to the arm to bring on the symptoms of pain, numbness and tingling in the hand, arm, and neck.

Can EMG detect TOS?

Electromyography/nerve conduction study (EMG/NCS) may be useful to exclude coexistent abnormalities such as peripheral nerve entrapment or cervical radiculopathy and is more useful in the diagnosis of true neurogenic TOS.

Can MRI diagnose TOS?

MRI is effective in diagnosing the source of compression in TOS, notably within the scalene triangle and at the pleural apex.

Can EMG diagnose thoracic outlet syndrome?

Electromyography may be helpful in confirming the presence or absence of a specific alternative diagnosis. A study reported that intravascular ultrasound detected greater levels of stenosis than venography in the treatment of 14 venous thoracic outlet syndrome patients.

What is the costoclavicular test?

The examiner palpates the radial pulse and then draws the patient’s shoulders down and back as the patient lifts their chest in an exaggerated “at attention” posture. A positive test is indicated by an absence or decrease in vigor of the pulse and implies possible costoclavicular syndrome.

What is the most reliable test for thoracic outlet syndrome?

Ultrasound. An ultrasound uses sound waves to create images of your body. It’s often the first imaging test used to help diagnose thoracic outlet syndrome. Doctors may use this test to see if you have vascular thoracic outlet syndrome or other vascular problems.

Can TOS cause shoulder pain?

Thoracic outlet syndrome (TOS) is a group of disorders that occur when blood vessels or nerves in the space between your collarbone and your first rib (thoracic outlet) are compressed. This can cause shoulder and neck pain and numbness in your fingers.
