Outline of Final Research Achievements

In this study we examined that the mechanism of contracture pain and peripheral nerve response. Rat ankle joints fixed in full planter flexion by plaster casts. We measured the range of motion and mechanical pain threshold of skin and muscles. The range of motion decreased by cast immobilization, and the contracture was created. And, the mechanical pain threshold of the skin and muscles decreased. We measured the muscle C-fiber activities of mechanical and heat threshold and responses to chemical solutions. But, there is little recorded number and the tendency is not clear.
