Simon King has been in practice 32 years. At a rough guess that's 25,000 patients, 130,000 visits and 6 million muscle tests.
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.
He had some early dramatic success and worked hard to disprove himself. Over 22 years, he never has. 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.
