On the Testimonials page you can read what other people have said about it. Probably far more helpful than my own definition, below, but here goes.
The Alexander Technique is a system of kinaesthetic learning which offers a radical approach to long-term muscle pain, harmful posture and under-performance in business, sport, music etc. The basis of the work is a set of skills learned in one-to-one weekly sessions. These embody the concept of “primary control” uncovered by F.M. Alexander over a century ago, as well as the potential for an “endless process of growth” described by Professor John Dewey. They are taught by gentle micro-manipulation and instruction, and address the root cause of these neuro-muscular problems.
“Common sense systematised” is one definition. My own is “Intelligence in action”.
I have received referrals from rheumatologists and neuro-surgeons for difficult cases.
In 2008 the British Medical Journal stated that for lower back pain the Technique was cost-effective and also showed benefits 12 months after treatment; it was recommended for NHS funding. Professor P Little who spearheaded this trial has been awarded a CBE for services to General Practice research.
In 2015 the Annals of Internal Medicine reported that the Alexander Technique was effective in reducing neck pain, including 12 months later.
In 2016 a scientific study provided validation for Alexander’s Primary Control principle.
