Let’s explore what TOS is, what causes it, how it’s treated, and how you can prevent it.
What is Thoracic Outlet Syndrome?
- 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).
- Venous TOS: Involves compression of the veins, potentially leading to swelling, discoloration, or blood clots in the arms.
- 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.
- Pain or numbness in the neck, shoulder, or arm
- Tingling or weakness in the hands
- Swelling or discoloration of the arm
- Fatigue or heaviness in the arm after activity
How Does Thoracic Outlet Syndrome Occur?
- Poor Posture: Slouching or forward-head posture can reduce the space in the thoracic outlet, increasing pressure on the structures within.
- Repetitive Motion: Overhead activities or repetitive arm movements, such as typing or lifting, can strain the muscles and tissues around the thoracic outlet.
- Trauma: Injuries such as whiplash or clavicle fractures can lead to TOS by altering the anatomy of the thoracic outlet.
- Congenital Anomalies: Some individuals are born with extra ribs (cervical ribs) or other anatomical variations that predispose them to TOS.
- 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
- Spinal Adjustments: To improve alignment and reduce pressure on the thoracic outlet.
- Soft Tissue Therapy: To release tight muscles and improve blood flow to the affected area.
- Postural Correction: Education and exercises to restore proper posture and reduce strain on the thoracic outlet.
3. Physical Therapy and Exercise
- Scapular Stabilization: Strengthening the muscles around your shoulder blades to support proper alignment.
- Neck Stretches: Reducing tension in the neck and upper trapezius muscles.
- Pectoral Stretches: Opening up the chest to relieve compression in the thoracic outlet.
Adjustments to your daily activities can help reduce symptoms. For example:
- Avoid carrying heavy bags on one shoulder.
- Take breaks from repetitive activities like typing or driving.
- Maintain proper posture during work or physical activities.
Preventing Thoracic Outlet Syndrome
Good posture is the foundation of a healthy musculoskeletal system. Focus on:
- Keeping your shoulders relaxed and down.
- Avoiding forward-head posture.
- Sitting with your back supported and feet flat on the ground.
Ensure your workspace is set up to reduce strain:
- Use an ergonomic chair and desk setup.
- Position your computer screen at eye level.
- Use a supportive keyboard and mouse.
