Thoracic Outlet Syndrome (TOS): Neurogenic Type Explained 🛑🦴👇
Thoracic Outlet Syndrome (TOS) may occur when nerves or blood vessels are compressed in the space between the neck and shoulder.
👉 The neurogenic type is the most common form
👉 It mainly affects the nerves supplying the arm
🧠 Concept Explanation
⚠️ 1️⃣ What is Neurogenic TOS?
👉 Neurogenic TOS may involve compression of the Brachial plexus
👉 These nerves control:
• Sensation in the arm and hand
• Muscle function
⚠️ 2️⃣ Where Does Compression Occur?
👉 The compression may happen in the Thoracic outlet
👉 This narrow space may become tighter due to:
• Muscle tightness
• Poor posture
• Structural variations
⚠️ Common Symptoms
👉 Neurogenic TOS may cause:
• Neck and shoulder pain
• Tingling (“pins and needles”) in arm or hand
• Numbness
• Weak grip strength
• Burning sensation along the arm
👉 Symptoms may worsen with:
• Raising arms overhead
• Carrying heavy objects
• Poor posture
⚠️ Possible Causes
1️⃣ Poor posture
👉 Forward head and rounded shoulders
2️⃣ Repetitive movements
👉 Overhead work or sports
3️⃣ Muscle tightness
👉 Especially chest and neck muscles
4️⃣ Injury or trauma
👉 Whiplash or strain
🛑 Risk Section
⚠️ If not managed:
• Symptoms may become chronic
• Muscle weakness may increase
• Daily activities may be affected
💡 Management & Care
✔ 1️⃣ Posture Correction
👉 Keep shoulders back and head aligned
✔ 2️⃣ Stretching Tight Muscles
👉 Focus on:
• Chest (pectorals)
• Neck muscles
✔ 3️⃣ Strengthening Exercises
👉 Improve:
• Upper back muscles
• Shoulder stabilizers
✔ 4️⃣ Activity Modification
👉 Reduce repetitive overhead strain
✔ 5️⃣ Physiotherapy
👉 May include:
• Nerve gliding exercises
• Postural training
• Manual therapy
🏃♂️ Helpful Exercises (Under Guidance)
👉 These may help:
1️⃣ Shoulder Blade Squeezes
👉 May improve posture
2️⃣ Chest Stretch
👉 May open the thoracic outlet
3️⃣ Neck Stretching
👉 May reduce nerve tension
4️⃣ Nerve Gliding Exercises
👉 May improve nerve mobility
⚠️ What to Avoid
❌ Slouched posture
❌ Carrying heavy bags on one side
❌ Prolonged overhead activities
❌ Ignoring symptoms
🚨 When to See a Doctor
👉 Seek medical advice if:
• Weakness increases
• Numbness becomes persistent
• Symptoms worsen over time
❤️ Final Thought
Neurogenic TOS may affect nerve function and cause discomfort in the arm and shoulder—but early posture correction and guided exercises may help manage symptoms effectively.
👉 Focus on alignment and muscle balance
👉 With consistency and proper care:
You may reduce symptoms and improve daily function
