FOREWORD

Dear Colleagues and Friends,
This book of papers represents the proceedings of lectures spoken at the 11th International Pain Clinic World Society of Pain Clinicians, which was held in Tokyo, Japan, from July 11 through 16, 2004. We had invited about 100 distinguished physicians from various countries and arranged a broad range of lectures in the field of medicine and extended lectures on pain mechanisms and management.
This book intends to respect the traditional academic research but at the same time seeks to liberate from them by using state of the art technologies to achieve ahead of its time. By doing so, we are able to gain the incentive to research and develop more.
I am certain that the debating of issues and exchange of information and opinions in this book by some of the world’s leading experts in the fast expanding and exciting field of pain management stimulates international cooperation as well as furthering studies in this area.
This book provides an opportunity for physicians, researchers and technicians from all over the world to make new recognitions of pain management.
This book contributes to the interflow and progress of science technology in pain management, as well as papers provides wonderful place of pain management.
For those of you who could attend the WSPC2004 Congress, this book will provide an accurate record of what took place and advances reported in our understanding of pain management. For those who could not join the WSPC2004 Congress, this book will help you to stay on the cutting edge of patient care and research as presented in Tokyo in July 2004.
I have no doubt that experimental and clinical research presented by the various authors will arouse substantial interests and serve as a stimulus to further progress of pain management.
