Address form the ChairIt is my great pleasure to announce the 4th International Biophilia Rehabilitation Conference in Berlin on September 23rd, 2005. One of the objectives of the conference is to make a global network for researchers and people who work for the rehabilitation medicine not only in the practical fields, but also in the basic research laboratories. I hope that we are able to provide the opportunity for doctors, nurses, occupational therapist, physical therapist, and policy makers to discuss on various kinds of issues that we are facing in the rehabilitation medicine around the world. This conference will also provide the unique opportunity for the comparative studies on various topics about rehabilitation medicine between Asia and European countries. I also hope that we will have the active discussions between basic researchers and practitioners in the symposia. To facilitate the communications, we are organizing the symposium on "Muscle Physiology in Elderly People" and the symposium on "Improvement from Impairment in the Disabled Elderly" as introduced in the website. My best wishes and regards,
