18 technical articles based on papers presented at a symposium held at the Universtiy of New South Wales in February 1981. Some articles provide a summary of existing knowledge on particular subjects, whilst others present relatively new reasearch (for 1981). The article 'Posture, proprioception and the Alexander Technique' is by Wilfred Barlow. Illustrated with appropriately specialist material. Many references and an index, but no glossary.
