Physiotherapy for Thoracic Outlet Syndrome: Evidence-Based Treatment Protocols
Thoracic Outlet Syndrome (TOS) is a complex and often misunderstood condition that results from compression of the nerves, arteries, or veins in the thoracic outlet—the space between the collarbone and the first rib. While it can affect anyone, it is especially common in athletes, desk workers, and individuals with poor posture or repetitive overhead movements. Fortunately, physiotherapy for Thoracic Outlet Syndrome offers non-invasive, evidence-based solutions to relieve symptoms and restore function.
If you’re seeking Thoracic Outlet Syndrome treatment in India, or searching for TOS physiotherapy in Bangalore, Mumbai, or Delhi, this comprehensive guide will walk you through everything you need to know about the condition and how physical therapy plays a crucial role in recovery.
Understanding Thoracic Outlet Syndrome (TOS)
TOS is broadly classified into three types:
- Neurogenic TOS: the most common type, caused by compression of the brachial plexus nerves.
- Venous TOS: due to compression of the subclavian vein.
- Arterial TOS: the rarest, involving compression of the subclavian artery.
Common symptoms include neck and shoulder pain, numbness or tingling in the arms, weakened grip strength, and even discoloration of the hands in vascular cases. Individuals may also report heaviness in the arms, especially after lifting or working overhead.
Causes and Risk Factors
Some of the key causes and risk factors associated with TOS include:
- Poor posture, particularly rounded shoulders and forward head position.
- Presence of a cervical rib or congenital abnormalities.
- Repetitive overhead activities common in athletes like swimmers, baseball pitchers, and weightlifters.
- Traumatic injuries such as whiplash.
- Occupational hazards, like desk jobs without ergonomic support.
Role of Physiotherapy in TOS Management
In most cases of neurogenic Thoracic Outlet Syndrome, physiotherapy is the first line of treatment and is often more effective and sustainable than surgical options. The goals of physical therapy are to reduce compression, correct posture, restore mobility, and strengthen the surrounding musculature.
Evidence-Based Physiotherapy Protocols for TOS
1. Postural Correction
Poor posture, especially forward head and rounded shoulders, narrows the thoracic outlet space. Posture correction for TOS using biofeedback, ergonomic adjustments, and mirror retraining is fundamental. A physiotherapist will teach you how to maintain proper alignment during daily activities.
2. First Rib and Scalene Mobilization
Tight scalene muscles and elevated first ribs are common culprits in neurogenic TOS. Manual techniques such as first rib mobilization for TOS, myofascial release, and scalene stretches are evidence-based methods to relieve compression.
Common stretches include:
- Scalene stretch for TOS
- Levator scapulae and upper trapezius stretches
- Pec minor and major stretches
3. Neurodynamic or Nerve Gliding Exercises
For nerve compression, nerve gliding exercises for TOS can be incredibly effective in improving neural mobility without aggravating symptoms. These exercises involve controlled limb movements that gently mobilize the brachial plexus.
4. Strengthening and Stabilization
Weak scapular stabilizers and poor muscle balance around the shoulder girdle can worsen symptoms. Your physiotherapist may introduce:
- Scapular retraction and depression exercises
- Rotator cuff strengthening
- Core and thoracic spine stabilization
These are essential components of a TOS rehabilitation protocol and prevent recurrence of symptoms.
5. Manual Therapy Techniques
Manual therapy for Thoracic Outlet Syndrome includes trigger point release, soft tissue mobilization, and joint mobilizations. These techniques help in relaxing tight muscles, reducing inflammation, and increasing thoracic mobility.
6. Therapeutic Modalities
Electrotherapy modalities like TENS, ultrasound, or dry needling can complement the rehabilitation process, especially in the initial stages when pain limits movement.
Exercises for Thoracic Outlet Syndrome Relief
Here are some TOS physiotherapy exercises that your therapist may guide you through:
- Doorway Pec Stretch: Opens up the chest and reduces anterior shoulder tightness.
- Chin Tucks: Strengthens deep cervical flexors to correct forward head posture.
- Wall Angels: Improves scapular mobility and posture.
- Thoracic Extension Over Foam Roller: Promotes mobility in the upper back.
Consistency is key, and these exercises must be performed under professional guidance, especially in the early phase.
When to Consider Surgical Options
While physiotherapy for Thoracic Outlet Syndrome is highly effective, some patients with arterial or venous TOS may require surgical decompression. However, even in those cases, pre- and post-operative physiotherapy can significantly improve outcomes and reduce recovery time.
Benefits of Physiotherapy for TOS
- Non-invasive and low risk
- Customizable protocols based on type and severity
- Addresses root causes like posture and biomechanics
- Reduces the need for medication or surgery
- Promotes long-term functional independence

Conclusion
Thoracic Outlet Syndrome can be debilitating if left untreated. But with timely diagnosis and an evidence-based TOS rehabilitation protocol, physiotherapy can offer lasting relief. From posture correction to first rib mobilization, manual therapy to nerve gliding, a comprehensive rehab plan targets the root cause not just the symptoms.
If you’re experiencing neck and shoulder pain, numbness in the arms, or signs of nerve and vascular compression, consult a physiotherapist trained in TOS management. Early intervention can prevent complications and help you regain optimal function.
