CMRT: Chiropractic Manipulative Reflex Technique

What is CMRT?

Chiropractic Manipulative Reflex Technique, commonly abbreviated as CMRT, is a specialised approach within Sacro Occipital Technique (SOT) that addresses the relationship between organ function and spinal health. CMRT is based on the concept of viscerosomatic reflexes — the idea that dysfunction in internal organs may manifest as changes in the musculoskeletal system, particularly in specific spinal regions.

It's important to state clearly at the outset that CMRT is one of the more controversial aspects of SOT. The theoretical basis — that spinal manipulation can directly influence organ function through reflex pathways — lacks robust scientific support. This article presents CMRT as it is practised while being transparent about the limitations of the current evidence.

The Concept of Viscerosomatic Reflexes

The foundation of CMRT lies in the concept of viscerosomatic reflexes. This concept suggests that when an organ is under stress or not functioning optimally, it may produce characteristic changes in specific areas of the spine and associated tissues.

How the Theory Works

According to CMRT theory, the nervous system creates connections between internal organs and the spinal column through the autonomic nervous system. When an organ experiences dysfunction, signals are thought to travel along these pathways, potentially causing:

• Increased muscle tension in specific spinal regions
• Changes in skin temperature or texture over affected areas
• Altered reflex responses
• Postural compensations

Conversely, the theory suggests that addressing these spinal changes through specific techniques may help support normal organ function by improving nervous system communication.

The Evidence Question

While the viscerosomatic reflex concept has some support in the physiological literature — it's well-established that organ disease can cause referred pain — the reverse proposition (that spinal manipulation can improve organ function) is far less established. Most systematic reviews have found insufficient evidence to support claims that chiropractic care directly treats organic disease.

Common CMRT Applications

CMRT techniques are typically applied to spinal regions associated with particular organ systems. It's crucial to understand that these applications are not treatments for the organ conditions themselves, but rather approaches that some practitioners believe may support overall nervous system function.

Digestive Considerations

The mid-thoracic spine (roughly T5-T9) is associated with digestive organs in CMRT theory. Practitioners may assess this region in patients with digestive complaints, though any such assessment should be in conjunction with appropriate medical evaluation for persistent digestive symptoms.

Respiratory Considerations

The upper thoracic spine (T1-T4) is linked to respiratory function in the CMRT framework. Techniques applied to this region are thought by some to support respiratory mechanics, though again, respiratory symptoms require appropriate medical assessment.

Circulatory Considerations

The upper thoracic and cervical regions are associated with cardiac and circulatory function. Any patient with symptoms suggestive of cardiovascular disease should be immediately referred for medical evaluation before considering chiropractic care.

What a CMRT Session Typically Involves

CMRT is typically incorporated into a broader SOT treatment session rather than delivered as a standalone therapy. The practitioner will:

• Assess spinal regions — Palpation of specific vertebral levels associated with organ systems
• Evaluate tissue texture — Assessment of muscle tension, skin changes, and other soft tissue findings
• Apply specific techniques
• Monitor response — Reassessment of findings after treatment

CMRT techniques are generally gentle and may involve light pressure, specific positioning, or low-force adjustments. Patients typically find the experience comfortable and relaxing.

The Evidence Base and Limitations

An honest assessment of CMRT requires acknowledging the significant limitations in the current evidence base. While SOT as a whole has some research support for musculoskeletal complaints, studies specifically examining CMRT and its effects on organ function are scarce.

A 2017 review in the Journal of Bodywork and Movement Therapies concluded that while viscerosomatic reflexes are a real physiological phenomenon, the clinical application of this knowledge through techniques like CMRT remains largely theoretical. The authors called for well-designed studies to explore these relationships more rigorously.

What this means for patients is that CMRT should be viewed as a complementary approach, not a replacement for medical care. Any claims that CMRT can "cure" or "treat" organ disease should be treated with appropriate scepticism.

When to See Your GP Instead

CMRT should never delay or replace appropriate medical care for organic disease. Seek medical evaluation for:

• Persistent digestive symptoms — Ongoing abdominal pain, changes in bowel habits, unexplained weight loss, or blood in stool
• Respiratory symptoms — Persistent cough, shortness of breath, chest pain, or coughing up blood
• Cardiovascular symptoms — Chest pain, palpitations, dizziness, or unexplained fatigue
• Urinary symptoms — Painful urination, blood in urine, or changes in urinary frequency
• Any new or worsening symptoms — Particularly in patients with known organ disease

A responsible chiropractor will always refer patients with potential organic pathology for medical evaluation. Chiropractic care, including CMRT, is appropriate for musculoskeletal complaints and general wellness support, not for treating organic disease.
