Who studies and why?
The Alexander Technique is a skill that be applied to activity in all walks of life. Though it is not a therapy as such it can be of therapeutic benefit (those suffering from joint disorders - bad backs*, necks etc., stress, RSI, breathing disorders and many other conditions have found the technique beneficial). *A recent study published in the British Medical Journal has shown that a course of Alexander technique lessons is highly effective in reducing back pain.Additionally, the technique is studied by performers (actors, musicians, dancers) to develop fluid, natural movement through which true self-expression can flourish without stage fright.
I firmly believe that the true place for the technique is with the young before they have developed strong habitual patterns that can harm health later in life.
