| Research Abstract |
Animal models of joint contracture after immobilization (casting) are known to develop long lasting painful behavior after cast removal. In this study, we obtainedup-regulations of brain and spinal microglia, astrocyte, C-Fos activities in this model animal. Present results suggest that functional changes of pain pathway occurredin brain and spinal cord level. Also we conducted treadmill exercise and passive stretching for therapeutic approach. Animals showed the improvement of painful behavior after both approaches.
