Training in the afferent input system refines your diagnostic skills while clarifying your thinking about the best way to approach every patient. 

Everything we teach is based on anatomy and neurology that has been known since 1906 and is common to all animals, yet is ignored by almost everyone in the medical and alternative fields because it relies on a different paradigm.

Instead of treating conditions (which are fictions anyway), we strengthen individuals. Through careful examination we determine each patient’s weakest link and then design treatments to return that system to normal. 

Online and live training leads to certification in Afferentology.

Our Free Course

Our Free Course gives you everything you need to understand the Afferent Input paradigm and get started with the basics of afferent input testing. You will come to understand your patients from a musculo-spinal reflex perspective.

Refine your Clinical Skills

The Afferent Input treatment paradigm brings an accuracy to your diagnosis and treatment you never dreamed possible. Everything we teach is designed to make every patient stronger, no matter what they are suffering from.

Learn Online or in Live Workshops

Our Online courses are the ideal precursor to our live workshops. You can learn all the theory and basics at home and be ready for a full day of hands-on practice. The Afferent Input system will clarify everything you already do and turbo-charge it in the process.

This Free Introductory Course covers everything a health professional needs to understand and begin to implement the Afferent Input System into their practice.

Your Instructor

Simon King has been in practice 32 years. 

In 1986 he qualified as a Diplomate in the ICAK and began teaching Applied Kinesiology.  In  May 2000, he went back to the textbooks and re-learned the neurology of muscles, specifically how muscle tone was controlled by muscle spindles and anterior motor neurons. When Lesley Pexton arrived in his practice, he knew he was onto something.

The theory produced some early dramatic sussess and although Simon worked hard to disprove it, the theory remains robust and reliable. The theory is not just sound, it is indisputable because it is the basis of all movement of all vertebrates.

Since then he has taught the paradigm and the techniques that derive from it to over a thousand practitioners, mainly chiropractors, osteopaths and physiotherapists and almost universally, they report how it has made their practice easier and more enjoyable because they can manage their patients more effectively.

“The most logical and rational approach to muscle testing, diagnosis and patient betterment that I have read, listened to or practiced.”

Mark Tucker


“Life changing is all I can say, phenomenal results and happy patients. Never been so content as a practitioner as I have been since learning these skills, thank you.”

Terry Coulits


“Just wanted to say THANK YOU for opening my eyes again to the effectiveness of correct and proper muscle testing and the amazing approach you have developed to find weak patterns and their cause that i would never have contemplated before attending your course. It has given me great confidence and has empowered me to help more people.”
