AT is a method of kinesthetic re-education developed by F.M. Alexander, who considered that the key to efficient control of bodily movement was the relation of the head to the neck and back, the “primary control” as he called it, a position of mechanical advantage. Alexander’s aim was to re-educate people kinesthetically in what he termed “good use”, a coordinated and balanced distribution of muscle tension throughout the body, resulting in an attentive state attainable under stress. Habitual, automatic reactions are inhibited and replaced by consciously controlled, directed actions. An important element is maintaining a state of openess with regard to the eventual act to be performed.
