Thoracic Outlet Syndrome

Do you experience persistent neck and shoulder pain, tingling in your fingers, or weakness in your arms? These symptoms might not just be the result of a tough workout or a long day at work. They could point to a condition called Thoracic Outlet Syndrome (TOS). At Peak Performance in Buffalo, NY, we specialize in addressing musculoskeletal issues like TOS with evidence-informed chiropractic and massage care.


Let’s explore what TOS is, what causes it, how it’s treated, and how you can prevent it.



What is Thoracic Outlet Syndrome?

Thoracic Outlet Syndrome is a group of disorders that occur when the nerves or blood vessels in the thoracic outlet—the space between your collarbone and first rib—become compressed. This compression can cause a variety of symptoms depending on which structures are affected.


Types of TOS:

  1. Neurogenic TOS: The most common type, involving compression of the brachial plexus (a network of nerves that controls muscle movements and sensations in your shoulder, arm, and hand).
  2. Venous TOS: Involves compression of the veins, potentially leading to swelling, discoloration, or blood clots in the arms.
  3. Arterial TOS: The least common type, caused by compression of the arteries, often leading to cold or pale fingers and weakened pulse in the arm.


Common Symptoms:



How Does Thoracic Outlet Syndrome Occur?

TOS develops when the thoracic outlet space becomes narrowed or constricted, leading to compression of nerves, veins, or arteries. Several factors can contribute to this, including:

  1. Poor Posture: Slouching or forward-head posture can reduce the space in the thoracic outlet, increasing pressure on the structures within.
  2. Repetitive Motion: Overhead activities or repetitive arm movements, such as typing or lifting, can strain the muscles and tissues around the thoracic outlet.
  3. Trauma: Injuries such as whiplash or clavicle fractures can lead to TOS by altering the anatomy of the thoracic outlet.
  4. Congenital Anomalies: Some individuals are born with extra ribs (cervical ribs) or other anatomical variations that predispose them to TOS.
  5. Athletic Activities: Sports that involve repetitive arm movements, such as swimming, baseball, or weightlifting, can increase the risk of developing TOS.




Treating Thoracic Outlet Syndrome

If you’re experiencing symptoms of TOS, it’s essential to seek professional evaluation. At Peak Performance in Buffalo, NY, we offer a range of treatment options tailored to your needs. Here’s how TOS is typically managed:


1. Chiropractic Care

Chiropractors can help by addressing postural imbalances and improving joint mobility in the neck, shoulders, and upper back. Treatments may include:


2. Massage Therapy

Massage therapy complements chiropractic care by targeting tight muscles and fascia around the thoracic outlet. Techniques such as trigger point therapy, myofascial release, and deep tissue massage can alleviate muscle tension and improve circulation.


3. Physical Therapy and Exercise

Strengthening and stretching exercises are vital for improving the function of the muscles that support the thoracic outlet. Common exercises include:


4. Lifestyle Modifications

Adjustments to your daily activities can help reduce symptoms. For example:


5. In Severe Cases

If conservative care doesn’t provide relief, more invasive interventions like corticosteroid injections or surgery may be necessary. Surgical options aim to remove the source of compression, such as a cervical rib or fibrous band.


Preventing Thoracic Outlet Syndrome

Preventing TOS is all about minimizing the risk factors that lead to compression of the thoracic outlet. Here are some practical tips to keep your thoracic outlet in top shape:


1. Prioritize Posture

Good posture is the foundation of a healthy musculoskeletal system. Focus on:


2. Ergonomic Adjustments

Ensure your workspace is set up to reduce strain:


3. Stay Active

Regular exercise helps maintain the strength and flexibility of the muscles supporting your thoracic outlet. Incorporate activities like yoga, Pilates, or swimming to promote mobility and stability.


4. Take Breaks

If your job involves repetitive arm or hand movements, take regular breaks to stretch and change positions. This helps prevent overuse injuries and muscle tension.


5. Listen to Your Body

Pay attention to any signs of discomfort or fatigue in your neck, shoulders, or arms. Addressing symptoms early can prevent them from worsening into a chronic condition.
