What You'll Master

✓ Proprioceptive Congruence vs. Dissonance

Understand how disrupted cervical inputs create sensory mismatch across the proprioceptive, vestibular, and visual systems — and why restoring congruence is essential for long-lasting change.

✓ The Complete P1 Test Protocol

Learn the two-part protocol using VOR-driven head–eye integration to reveal the exact cervical joint producing aberrant mechanoreceptor signalling. This rapid assessment exposes the joint’s vector of failure and shows how the body attempts to stabilise itself through subtle, unconscious head positioning.

✓ Clinical Application & Interpretation

Recognize positive test indicators, understand why patients “choose” certain compensations, and learn to translate P1 findings directly into precise, low-load Adjusting to Neutral corrections.

✓ Advanced Diagnostic Integration

See how P1 findings strengthen your interpretation of eye movement behaviour, VOR asymmetries, cervicocolic reflex activation, and autonomic responses — supporting a complete, neurologically coherent treatment plan.

Who Should Attend

• Chiropractors frustrated by patients who improve temporarily but never stabilize

• Clinicians seeking clarity in complex cervical presentations

• Practitioners who value neurology-based assessment over trial-and-error adjusting

• Students and graduates wanting diagnostic skill that scales into mastery

• Experienced doctors refining precision in chronic or ambiguous cases

What Makes This Different

The P1 Test is not another motion-palpation variant — it is a concise neurological evaluation that identifies the joint producing the brain’s primary proprioceptive error. In under a minute, you can determine the responsible segment, its vector of failure, and the exact correction needed to regain tonic congruence at a level that meaningfully influences brainstem and cerebellar control of posture and movement.
