Thoracic Outlet Syndrome Treatment in Joondalup and Perth's Northern Suburbs

Arm pain, numbness, or weakness that comes from the neck and shoulder region — thoracic outlet syndrome is often missed or misdiagnosed, and conservative care is the recommended first approach.

Thoracic outlet syndrome, or TOS, occurs when nerves or blood vessels are compressed in the space between the collarbone and the first rib.

It can produce arm and hand symptoms that look similar to cervical radiculopathy or carpal tunnel syndrome. The most common form is neurogenic TOS, where the brachial plexus is compressed.

Often Neurogenic The brachial plexus is the most commonly compressed structure
Conservative First Non-surgical management is generally recommended initially

Understanding the condition

What Causes Thoracic Outlet Syndrome?

The outlet may narrow because of muscular tension, posture, anatomy, repetitive overhead activity, or altered neck and shoulder mechanics.

  • Tight scalene muscles in the neck compressing the brachial plexus between them
  • A tight pectoralis minor muscle compressing the plexus against the rib cage
  • Rounded shoulders and forward head posture narrowing the outlet space
  • A cervical rib, which is a small extra rib present from birth in some people
  • Repetitive overhead activity or a history of whiplash that has altered neck and shoulder mechanics

Common signs

Symptoms

Symptoms commonly affect the neck, shoulder, arm, and hand and may worsen when the arm is held overhead.

  • Aching, heaviness, or pain in the arm, shoulder, or neck
  • Numbness or tingling in the arm, often in the ring and little fingers
  • Weakness in the arm or hand
  • Symptoms that worsen with overhead activity or sustained arm elevation
  • In vascular TOS, which is less common, colour changes, swelling, or coldness in the hand
Clinical evidence

What the Research Shows

The evidence base remains limited, but conservative management is consistently recommended before surgical discussion.

  1. High-quality randomised trials for thoracic outlet syndrome are scarce, and the overall evidence base remains limited.
  2. A 2024 case report by Glowa and Trybulec documented significant improvements in pain, cervical range of motion, and clinical test findings in a young athlete with neurogenic TOS using trigger-point therapy, deep-tissue massage, and cervical manipulation over eight sessions.
  3. The reported improvements were maintained at the one-month follow-up.
Individualised care

How We Can Help

Care considers the structures compressing the outlet, the mobility of the brachial plexus, first-rib position, posture, and the activities that provoke symptoms.

We focus on the anterior and middle scalenes, which are the primary muscular compressors of the brachial plexus in neurogenic TOS, and the pectoralis minor, which compresses the plexus from the front.

Releasing these two muscle groups often produces the most immediate symptom reduction.

Learn more about Soft Tissue Therapy

We mobilise the first rib, which in TOS is often elevated and sitting against the scalenes in a way that closes the outlet from below. We also mobilise the lower cervical and upper thoracic spine, which directly affects scalene tension and brachial plexus mechanics.

We may needle the scalenes, subclavius, and pectoralis minor, which are the three muscles most likely to be compressing the outlet.

These muscles are often chronically hypertonic in TOS and may respond to needling when manual release alone is insufficient.

Learn more about Dry Needling

We apply brachial-plexus tensioning and sliding techniques to restore the nerve's ability to move freely through the outlet as the arm is elevated, reducing the neural tension that produces arm and hand symptoms.

Cold laser may be applied along the brachial-plexus pathway from the neck through the shoulder to reduce perineural inflammation and support nerve-tissue recovery, particularly when symptoms have been present for months.

A shoulder-retraction and first-rib-depression taping technique may help hold the outlet in a more open position during the day, particularly when work posture is a major driver of compression.

Learn more about Kinesiology Taping

We prescribe scalene and pectoral stretching, deep-neck flexor strengthening, and thoracic-extension work to address the postural pattern driving the compression over the longer term.

Without addressing the postural component, hands-on treatment alone may not hold.

When referral may be needed

Vascular or Progressive Symptoms Require Further Review

If vascular TOS is suspected, or if symptoms are severe and progressive with signs of muscle wasting, we will refer you promptly for specialist review.

The large majority of TOS presentations are neurogenic and are well suited to conservative management.
