In 1906 Sir Charles Scott Sherrington changed how we think about movement, yet most health professionals are unaware of how his discoveries impact their patients every day.

This FREE Course explains how cord-based reflexes work. I have made it as quick and easy as possible.

It is designed to help practitioners understand how reflexes control movement and prevent injury.

You can use this information to help their patients prevent and recover from injury and illness faster than ever before.

The course is a mixture of video and text and is the necessary background you will need to progress to learning how to change afferent input to help your patients get better faster than ever before.

Charles Sherrington

When Sir Charles Scott Sherrington published “The Integrative Action of the Nervous System” in 1906, he revolutionised the way we think about the human body and movement.

“Sherrington found that reflexes must be regarded as integrated activities of the total organism, not as the result of the activities of isolated “reflex arcs,” a notion that was currently accepted. The first major piece of evidence supporting “total integration” was his demonstration (1895–98) of the “reciprocal innervation” of muscles, also known as Sherrington’s law: when one set of muscles is stimulated, muscles opposing the action of the first are simultaneously inhibited.” (

The reflexes he discovered are covered in every modern textbook of anatomy, physiology and neurology but the clinical consequences of those reflexes are virtually ignored in modern medical practice and research.

Afferent Input is a paradigm available to all healthcare practitioners that brings new tools and a fresh set of eyes to the examination and treatment of patients.

In this FREE COURSE we will cover

  1. The Myotatic Reflex
  2. Reciprocal Inhibition
  3. The Withdrawal Reflex

PLUS You’ll get An Introduction to Afferent Input
and Some Bonus Videos and Special Offers.

It is amazing that 100 years after Sherrington’s discoveries, most health professionals still seem to think that muscle tone is a conscious activity. They give exercises, ergonomic advice and postural advice in the belief that these will change muscle tone. They won’t, except in the moment, obviously.

When you understand how muscle tone is generated and how reflexes control movement, providing genuine and lasting improvements for your patients will become second-nature.

The Association of Afferent Input Practitioners is a group of highly talented and enthusiastic health professionals from a variety of backgrounds who fully endorse the paradigm and use it like a “plugin” to make any physical treatment easier and more effective for their patients.

If you’re a licensed health professional, you will be eligible for membership after training in afferent input either online or in our live seminars.

This short introduction aims to explain muscle function. It will show that while our brain obviously has a part to play, the vast majority of muscle contraction is totally subconscious and controlled by REFLEXES.

We will learn how the first stage of reflex muscle control is afferent input from proprioceptors, mainly the muscle spindles and we will discover how that input can be abnormally inhibited, leading to injury, pain and disability.

We will see how the Afferent Input paradigm challenges the notion that the brain controls the body, how the brain is a processing centre that connects the mass of incoming signals in a way that creates the totality of output we recognise as movement and function and how our every thought and action starts life as an incoming nerve signal.
We will discover that our nervous system is controlled from the outside-in.
