Regional Synchronization is unique because it doesn’t just look at single vertebrae or isolated joints. Instead, it examines how the head, upper torso, and lower torso synchronize around gravity predominantly influenced by three “centered bones” — the Sphenoid (head), C5 (upper torso), and L3 (lower torso).
Here’s what makes it stand out:
1. Triad of Centered Bones
Most chiropractic models focus on the atlas (C1) or pelvis. McArthur emphasizes the Sphenoid, C5, and L3 as the true structural centers — each aligned on the X, Y, and Z gravitational axes. Their relationship determines the body’s global balance state.
2. Pattern-Based, Not Symptom-Based
Instead of chasing pain or individual subluxations, it identifies predictable balance patterns (ipsilateral, contralateral, borderline) that reveal how the body is compensating.
3. Binary Balance Law
It applies the principle that no bone is “off” by itself; every misalignment has a counterbalance elsewhere. This binary relationship helps chiropractors understand why distortions occur instead of just where.
4. Integration of Reflexes
Regional Synchronization ties balance into the body’s reflex systems (vestibulo-ocular, vestibulo-spinal, vestibulo-collic), showing how posture corrections are neurologically driven, not just mechanically.
5. Head–Torso–Pelvis Unity
Unlike many approaches that treat spinal regions separately, this model insists the head, upper torso, and lower torso must synchronize together for true correction — restoring plumb centering across all three.
In short, Regional Synchronization is unique because it provides a systematic way to decode the body’s balance language, making adjustments more precise, predictable, and in harmony with innate intelligence.
