1998:14 Eighth International Conference on Hand-Arm Vibration 9–12 June 1998, Umeå, Sweden Abstracts Edited by: Ronnie Lundström Lage Burström Tohr Nilsson Sonya H␣ Bylund arbetslivsrapport ISSN 1401-2928 Department of Technical Hygiene Head: Ulf Landström National Institute for Working Life 8th International Conference on Hand-Arm Vibration. i Preface This is the eighth International Conference on Hand-Arm Vibration and is held in Umeå. The first conference was held in Dundee in 1972 followed by Cincinnatti (1975), Ottawa (1981), Helsinki (1985), Kanazawa (1989), Bonn (1992) and Prague in 1995. I have had the opportunity to attend the last four conferences and I believe that this series of conferences has become an important meeting point for all of us who have an interest to learn more about different aspects associated with occupational exposure to hand-arm vibration. One major advantage with these conferences, at least in my point of view, is not only the possibility for scientists and experts to meet and exchange information within the area of their particular interest, but also the possibility to collect and exchange knowledge from other areas. As human response to vibration clearly is a multi- disciplinary problem it is of course of utmost importance that people from all disciplines can get an opportunity to meet. I think a multi-disciplinary approach is essential for better understanding of the relation between vibration exposure and related injuries. I am sure that this series of international conferences, which includes sessions of both technical and medical nature, plays an important role in this respect. This conference is organized under the auspieces of: - Intenational Commission on Occupational Health (ICOH), Scientific Committee Vibration and Noise (SCVN) - International Advisory Committee of International Conferences on Hand-Arm Vibration - European Research Network on Detection and Prevention of Injuries due to Occupational Vibration Exposures. On behalf of the National Organizing Committee, the International Advisory Committee, the National Institute for Working Life, the Västerbotten County, the City of Umeå and my co-editors for this book of abstracts I wish to express my gratitude to the contributing authors, session chairmen, participants who presented papers, exhibitors and sponsors for making this conference feasible. Finally, I would like to mention that without enthusiastic work by members of the National Organizing Committee, Conference secretariat, staff at NIWL’s Department of Technical Hygiene and KONFERERA Conference Bureau, this meeting would not have been possible to realize.
