It’s really tough being a patient.

Once you’ve run the gauntlet of “free” options of NHS, Dr Google and your mother, you don’t know where to turn. 

Sadly, nearly every profession will offer you a treatment, very few will offer you a real diagnosis. 

A real diagnosis leads to the right treatment, one that will rid you of the current problem and prevent it returning. Ideally, you want a diagnosis that will not only alleviate your current problem but will also leave you stronger and more robust to prevent any future problems. That’s true preventative medicine.

That’s where I come in.

I’m Simon King. I’ve been guiding patients towards effective health strategies for over 30 years.

We know that modern medicine doesn’t work very well for most conditions outside trauma and emergencies. 

Twenty years ago I was lucky enough to stumble upon an idea that changed everything for me and my patients. 

I think we all know that Nature works best with no interference. What most of medicine fails to appreciate is that foreign bodies often create interference to our nervous system that reduces our ability to function normally.

The reason we can move and survive in our environment is because our nervous system has an almost limitless capacity to sense our surroundings and then keep us safe from injury through movement. It does this through muscle control and muscle reflexes.

Although most doctors test the knee-jerk reflex, that’s only one reflex, in one muscle, without any regard as to what that reflex is doing in real life. That reflex is essential to prevent ANY and ALL injury and pain, and it needs to be tested in every muscle under a wide range of conditions. 

This change in my thinking lead me to develop a new style of diagnosis and treatment which I called AFFERENT INPUT.

An afferent input practitioner finds and fixes abnormal muscle inhibition because muscle inhibition is what causes most pain, injury and degeneration. It’s weakness, not of the muscle itself, but of the nerve supply to the muscle. 

I documented my discoveries in my book “Live Without Pain” which is free to read online and to borrow from the clinic. You will find many videos of patients being treated with this system on this website.

Over the last 20 years I have taught my system to over 800 chiropractors, osteopaths and physiotherapists all over the world and I run a thriving association of health professionals who I continue to teach and mentor.

You can find me at the Naturality Wellness Centre in Berkhamsted.

It is my aim to return you to the best possible health in the least possible time by spending the least possible money. In one experiment I ran, my treatment produced an average 34% increase in strength (in one visit). According to over 60 studies, increasing strength translates into a longer and healthier life.

I am in the clinic Mondays, Wednesdays, Thursdays and Saturdays.

The majority of my patients find me when they are referred by other health practitioners but referral is not necessary. I love helping athletes, and anyone with chronic pain and disability. I’m equally happy checking “well” people to make sure they are going to stay that way.
