| Outline of Final Research Achievements |
The purpose of this study was to examine the time-dependent changes in the development of joint capsule fibrosis and in the number of myofibroblasts in the joint capsule after immobilization and effects of vibration on jonit contracture, using a rat knee contracture model.
This study revealed that joint capsule fibrosis with overexpression of type I collagen occurs and progresses within 1 week after immobilization, and an increase in myofibroblasts is related to the mechanism of joint capsule fibrosis. However, it was indicated that the immobilization-induced joint contracture might not be inhibited by vibration stimulator.
