Sacro Occipital Technique (SOT): A Complete Patient Guide

What is Sacro Occipital Technique (SOT)?

Sacro Occipital Technique, commonly known as SOT, is a comprehensive chiropractic method that focuses on the relationship between the sacrum (the triangular bone at the base of your spine) and the occiput (the base of your skull). This relationship forms what practitioners call the craniosacral mechanism.

Developed in the 1920s by Dr Major Bertrand DeJarnette, an American chiropractor and osteopath, SOT has evolved into one of the most widely practised chiropractic techniques worldwide.

How Does SOT Work?

The Craniosacral Mechanism

At the heart of SOT is the concept of the craniosacral mechanism — the continuous system of membranes, fluid, and bones extending from the cranium down through the spine to the sacrum. Cerebrospinal fluid (CSF) bathes and protects the brain and spinal cord within this system.

The Three Category System

SOT uses a classification system dividing patients into three categories:

Category I — Relates to craniosacral respiratory mechanism and CSF dynamics, often affecting the entire system.

Category II — Focuses on sacroiliac joints and pelvic stability, addressing sacrum and pelvic bone relationships.

Category III — Deals with localised spinal issues, particularly lumbar disc and structural problems.

What to Expect During an SOT Session

Initial Consultation

Your first visit involves a comprehensive health history and physical examination. The practitioner uses specific indicators to determine your category and identify dysfunction areas.

The Blocking Procedure

A distinctive feature of SOT is the use of “blocks” — wedges placed under specific areas of your pelvis while you lie face-down. Your body weight and gravity help encourage the pelvis and sacrum toward optimal position.

Session Duration

Initial consultations last 45–60 minutes. Follow-up sessions are typically 15–30 minutes.

Conditions That May Respond to SOT

While SOT doesn’t treat specific diseases, patients commonly seek care for:

• Back Pain — SOT’s pelvic alignment focus makes it relevant for many back pain types
• Headaches and Migraines — Attention to cranial mechanics may help certain headache patterns
• Neck Pain — Gentle techniques suitable for neck complaints
• Pelvic and Hip Issues — Sacroiliac dysfunction and pelvic girdle pain
• Postural Problems — Whole-body approach may improve postural patterns

SOT Training and Certification in Australia

Chiropractors must complete a five-year university degree and register with AHPRA. SOT training is available through SOTO Australasia:

• Basic Certification — Fundamental principles and procedures
• Advanced Certification — Complex cases and additional techniques
• Craniopath Certification — Advanced cranial techniques

Is SOT Evidence-Based?

Research supporting chiropractic care exists, particularly for low back pain. A 2019 systematic review in the Journal of Chiropractic Medicine found some support for SOT in low back pain, though more high-quality studies are needed.

When to See Your GP Instead

Seek medical attention for:

• Severe neurological symptoms (weakness, numbness, loss of bladder/bowel control)
• Sudden severe headache
• Recent significant trauma
• Fever with back pain
• Unexplained weight loss
• History of cancer with new pain

Conclusion

SOT offers a gentle, whole-body approach to chiropractic care. Its low-force nature makes it suitable for many patients seeking an alternative to traditional manual adjustments.
