This one is for you PTs out there.
Robin McKenzie (April 20, 1931 – May 13, 2013) is a physical therapist from New Zealand most notable for his development, in the 1950s, of the McKenzie Method of Mechanical Diagnostics and Therapy (MDT) aka the McKenzie Method (which, it should be noted, involves more than just extension exercise contrary to a certain member of the general public who shall remain anonymous lol).
Born in Auckland, McKenzie graduated in 1952 as a physical therapist from the New Zealand School of Physiotherapy in Dunedin and, in 1953, started a private practice in Wellington.
It was at this practice, in 1956, that McKenzie first observed what he called the “Centralisation Phenomenon” when a patient had resolution of three week old low back pain with referral into the buttock and back of knee after spending time in a passive prone position (funnily enough, I’m told that passive release technique was essentially “discovered” in this exact same manner by an Osteopath who had no idea how to treat a patient and left him in the most comfortable position he could find while the Osteopath went and consulted his text books about what to do).
It was in the 1970s that the McKenzie Method began to gain traction overseas and in 1982 the McKenzie Institute was established to carry out further education and research. As of 2019 there are currently 29 branches of the McKenzie Institute across the world.
McKenzie has received global recognition for his work and has received numerous honors including (but not limited to) being awarded honorary life membership in the American Physical Therapy Association (APTA) in 1982, being made an Officer of the Most Excellent Order of the British Empire in 1990 and being awarded as a Companion of New Zealand Order of Merit.
