The Afferent Input System

for Health Professionals

Techniques to Make Every Patient as Strong and Robust as Possible.


If you're a health practitioner, you're already using afferent input. Every time you touch, massage, adjust, mobilise, manipulate, needle, exercise or rehab a patient, you're doing afferent input.


What if you could do it consciously, deliberately and predictably?


You would no longer wonder about those patients who just refuse to get better despite the best treatment you can provide.

Ultimately, sensory input informs and controls motor output - largely via cord-based reflexes.



The Association of Afferent Input Practitioners offers qualified health professionals training in how to integrate Afferent Input principles into their current practice.


How to Find and Fix Muscle Inhibition 

Our first paid course is created and presented by Simon King, the Founder of the Association.


It includes 3 hours of video (3 hours CPD) in 10 bite-sized lessons. 


They are a mixture of lecture, clinical demonstration and seminar footage which teaches any health practitioner to assess and care for difficult and complex patients with ease, in accordance with their professional qualification. 


What's included?

  • How to Test for Weakness 


    You'll learn how to test for muscle inhibition.

    "Muscle inhibition" is the silent epidemic behind all injury and most illness, but you'll never know how common it is if you don't test for it.


    Muscle testing often gets bad reviews because people do it wrong. This course will teach you to test for the natural strength that gives us strength, resilience and vitality. 


    There is NO point in giving exercises if you don't know whether your patient has weakness or inhibition. Weakness can be helped with exercise, inhibition can not. 


    In this course you'll learn how to find and fix muscle inhibition quickly and permanently.

  • Learn how to test EVERY muscle

    You'll learn how to test EVERY muscle, even the ones that "can't" be tested.


    Within every muscle fibre are muscle spindles signalling exactly what tension each muscle is under and the length of that muscle.


    Learn how to extract that information so you can return the tone of every muscle to normal, not too tight and not inhibited (I was going to say "too loose", I know that's not right but it is more Goldilocks).

  • How to Find and Fix Hypertonicity

    Just as some muscles can be inhibited, others can be too tight. 

    We give you simple techniques to determine whether a patient is just super strong or actually abnormal in their muscle tone, PLUS, we teach you how to overcome hypertonicity permanently. 


  • Solve difficult patients

    Not every patient is straight-forward.


    Some patients have local inhibition and weakness, others have bilateral weakness, multiple weaknesses and a few present with global weakness.


    This course gives you the tools (principles) you need to solve all these.


    It doesn't matter what condition your patient presents with. There is no downside to making any patient stronger and more robust.

  • Nutritional Testing

    Once you have found muscle inhibition we run through many treatment options.

    Global muscle inhibition is often due to a deficiency or a toxicity.

    We use Afferent Input techniques to work out exactly what your patient is deficient in or what might be causing their toxicity so you can better advise them on the environment that might be affecting them or the diet and/or supplements that could help them. 

  • Dentistry

    Although it's not a big part of the course, we provide many examples and reasons why dentistry is the origin of many afferent input disturbances.

  • Jewellery

    One of the major overlooked causes of abnormal afferent input is metal jewellery, especially piercings.


    Using strength as your guide, you will be able to determine if jewellery is preventing the recovery of your patient. 

This course is the starting point for any health practitioner who wants to get better at patient-specific diagnosis. 


The tools you learn here can be integrated with any technique and training you currently use, and it will help you use them better.

  • PLUS 30 days access to our Private Facebook Group

    If you need help putting these techniques to work, we've got you covered.

    Our private facebook group is full of friendly practitioners willing to offer help and advice. They have been there and done that. You can ask anything you want and get all sorts of bonus materials and support.



    Ever wondered why you get one patient better in 2-3 visits and another with an almost identical presentation takes forever or doesn't get better at all? This course will help you understand why and teach you what to do about it.


    It's hard not to lose sleep over those patients who aren't doing well. Maybe you can switch off after you've "done your best" but if you ever wondered whether you missed something, you are going to love this course.


    Population-based studies can't help you with an individual patient, unless you like gambling. You need solid information to base clinical decisions on and afferent input gives you that. Everything we teach is true of every vertebrate, any animal with a nervous system and quite a few that don't have one (not that you're likely to be treating amoeba!).

Just wanted to thank you for the great courses, and I am using the knowledge from the courses on every patient I have, and they couldn’t be happier. This really is accelerates the Philosophy from structure to function.

Leif Petter Sigmundstad

Physiotherapist, Sweeden

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.

Mark Tucker

Chiropractor, London

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

Terry Coulits

Chiropractor, Sydney

I'm Simon King, a clinician who has been in practice 32 years. At a rough guess that's 25,000 patients, 130,000 visits and 6 million muscle tests

I've always tested muscles. In the early days it
.just seemed the right thing to do. I liked being able to test something, correct it and check whether I had done what you set out to do. Little did I know then, that the muscle tone I was testing was the key to health and longevity.


In 1986 I qualified as a Diplomate in the ICAK and began teaching Applied Kinesiology but I was frustrated that nobody seemed to have a solid grasp on what caused the weaknesses practitioners would find with AK. In  May 2000, I 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. I wondered if what really made muscles weak was not "energy" but changes in sensory input. 

I had some early dramatic success with my new theory but aware of confirmation bias I worked hard to disprove myself. Over 22 years, I never have. The theory is not just
sound, it is indisputable because it is the basis of all movement of all vertebrates.


Since then I have taught the paradigm and the techniques that derive from it to over a thousand practitioners, mainly chiropractors, osteopaths and physiotherapists and almost universally, they tell me how it has made their practice easier and more enjoyable, as well as getting their patients better results faster.
