What Is Neurogenic Thoracic Outlet Syndrome? Causes, Symptoms
Neurogenic thoracic outlet syndrome is a condition that occurs when the nerves in the neck and shoulder are compressed, leading to pain and discomfort. This can happen due to various reasons, such as poor posture or repetitive movements. It is essential to seek medical advice if you experience any unusual sensations in your arms or hands. By understanding the causes of neurogenic thoracic outlet syndrome, you can take steps to prevent it and alleviate potential symptoms. Remember to consult a healthcare professional for proper diagnosis and treatment options.
What Are the Symptoms of Neurogenic Thoracic Outlet Syndrome
Neurogenic thoracic outlet syndrome symptoms often include pain, tingling, weakness, or numbness in the neck, shoulder, arm, or hand. Patients may also experience a feeling of heaviness or swelling in the affected area. These symptoms can worsen with certain activities like overhead reaching or prolonged sitting. Seeking prompt medical evaluation is crucial for proper diagnosis and management.
- Tingling or numbness in your fingers or hand, especially when using your arms overhead or carrying heavy objects.
- Weakness in your hand or arm, making it difficult to grasp or hold onto items.
- Pain in the neck, shoulder, or arm that worsens with certain movements or activities.
- Swelling or discoloration of the hand or arm due to compromised blood flow.
- Muscle atrophy or visible changes in the shape of your hand or arm, indicating nerve damage.

This compression can be due to factors such as poor posture, repetitive overhead movements, trauma, or anatomical variations in the area. Additionally, muscle imbalances and tightness can contribute to the development of this condition by further compressing the nerves and blood vessels in the thoracic outlet.
- Trauma, such as car accidents or sports injuries, can lead to neurogenic thoracic outlet syndrome by causing compression of the nerves in the thoracic outlet.
- Repetitive motion activities, like typing or carrying heavy loads, can contribute to the development of neurogenic thoracic outlet syndrome due to chronic nerve compression.
- Poor posture, especially when sitting or standing for long periods with shoulders hunched forward, can increase the risk of neurogenic thoracic outlet syndrome by putting pressure on the nerves in the neck and shoulder region.
- Anatomical variations, such as an extra rib or abnormal muscle development in the thoracic outlet area, can predispose individuals to neurogenic thoracic outlet syndrome by narrowing the space through which
Types Of Neurogenic Thoracic Outlet Syndrome
- True neurogenic thoracic outlet syndrome (TOS) is characterized by compression of the brachial plexus nerves, leading to symptoms such as pain, weakness, and numbness in the arm and hand.
- Arterial thoracic outlet syndrome occurs when there is compression of the subclavian artery, resulting in symptoms like coldness, discoloration, and diminished pulses in the affected arm.
- Venous thoracic outlet syndrome involves compression of the subclavian vein, causing symptoms such as swelling, heaviness, and prominent veins in the arm.
- Neurogenic TOS secondary to cervical rib refers to compression of nerves or blood vessels due to the presence of an extra rib in the neck
Risk Factors
Risk factors for neurogenic thoracic outlet syndrome include repetitive overhead arm movements, poor posture, trauma or injury to the neck or shoulder, presence of a cervical rib, and certain anatomical variations. Additionally, occupations that require repetitive arm movements or prolonged periods of sitting can also increase the risk of developing this condition. Early recognition and intervention are crucial for managing symptoms and preventing complications.
- Repetitive overhead arm movements, such as in athletes or manual laborers, can increase the risk of developing neurogenic thoracic outlet syndrome due to compression of nerves and blood vessels in the thoracic outlet region.
- Poor posture, especially slouching or rounding the shoulders forward, can contribute to nerve compression in the thoracic outlet and raise the likelihood of developing neurogenic thoracic outlet syndrome.
- Trauma or injury to the neck or shoulder area, such as from a car accident or fall, can lead to structural abnormalities that may result in nerve compression and the onset of neurogenic thoracic outlet syndrome.
- Certain anatomical variations, like having an extra rib or a cervical rib, can predispose individuals to neuro

Diagnosis of Neurogenic Thoracic Outlet Syndrome
Your doctor will check for symptoms like arm weakness or tingling and may perform specific maneuvers to evaluate nerve function. Nerve conduction studies can measure the speed of nerve signals, while imaging tests like MRI or ultrasound can show any nerve compression. Early diagnosis is key for effective treatment.
- Physical Examination: A thorough physical examination by a healthcare provider can help identify symptoms such as weakness, numbness, and tingling in the affected arm.
- Electromyography (EMG): EMG testing can assess nerve and muscle function to detect any abnormalities caused by compression of the nerves in the thoracic outlet.
- Nerve Conduction Studies: These studies evaluate how well electrical impulses travel along the nerves, helping to diagnose nerve compression in the thoracic outlet.
- Imaging Tests: Imaging modalities such as MRI or CT scans can provide detailed images of the structures in the thoracic outlet, aiding in identifying any abnormalities or compression.
- Provocative Tests:
Treatment for Neurogenic Thoracic Outlet Syndrome
Treatment options for neurogenic thoracic outlet syndrome may include physical therapy to strengthen muscles, improve posture, and reduce nerve compression. Pain management techniques like medication or injections may also be recommended. In severe cases, surgery to relieve pressure on the affected nerves or blood vessels may be necessary. Lifestyle changes, such as ergonomic adjustments and avoiding repetitive movements, can also help manage symptoms.
- Physical therapy focused on strengthening and stretching exercises can help improve muscle imbalances and postural issues that contribute to neurogenic thoracic outlet syndrome.
- Nerve gliding exercises, under the guidance of a physical therapist, can help mobilize the affected nerves in the thoracic outlet region, reducing symptoms such as pain and numbness.
- In severe cases where conservative treatments have not provided relief, surgical intervention may be considered to decompress the structures causing nerve compression in the thoracic outlet.
- Lifestyle modifications such as maintaining good posture, avoiding repetitive overhead movements, and incorporating ergonomic adjustments in daily activities can help manage symptoms and prevent exacerbation of neurogenic thoracic outlet syndrome.
