Some 42 million Japanese and about half of all adult Danes frequently experience unexplainable muscle pains. Now Aalborg University in northern Jutland, Denmark, and Nagoya University in Japan, are commencing a 3-year research project that will attempt to find the cause of these muscle pains, and how to relieve them, Aalborg University writes in a press release.
Professor Thomas Graven-Nielsen at the Center for Sensory-Motor Interaction, Aalborg University, says: "Everyone has some small 'trigger-points' in their muscles which hurt when you press on them. They can cause headaches, lower back pain and other discomforts, and in a lot of patients it develops into stronger pain. We don't yet know why, but we hope to find out."
Professor Graven-Nielsen's counterpart at Nagoya University, Professor Kazue Mizumura, comments: "The treatment of this type of pain is not optimal today. In our animal experiments we can make studies which are not possible in humans. So the results from the Japanese group's animal experiments supplement the studies that the Danish group is making."
She hopes that the experiments and the new knowledge will make it possible to prevent the pains developing and help find a more effective treatment.
The project is the first result of a common agreement concerning clinical research projects between Denmark and Japan. It is supported by the Danish Agency for Science, Technology and Innovation and from the corresponding Japanese organisation, Japan Science and Technology Agency.
