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 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
• Category II — Focuses on sacroiliac joints and pelvic stability
• Category III — Deals with localised spinal issues, particularly lumbar problems

What to Expect During an SOT Session

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.

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

Conditions That May Respond to SOT

• 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

Finding an SOT Chiropractor

All chiropractors in Australia must register with AHPRA. SOT training is available through SOTO Australasia.

When to See Your GP Instead

Seek medical attention for severe neurological symptoms, sudden severe headache, recent significant trauma, fever with back pain, unexplained weight loss, or history of cancer with new pain.
