Research Abstract |
The aim of the present study was the development of an effective therapy of chronic pain. In order to achieve it, we performed a series of experiments to confirm whether the preventive exercise is effective against the chronic pain. We let a group of rats exercise voluntary for 2 weeks using running wheel, while the other group did not do the exercise. Then we made chronic post-cast pain (CPCP) model and performed behavioral and immunohistochemical examination. We found that the chronic mechanical hyperalgesia in rats that exercised before CPCP was induced was more decrease compared with the rats that did not do the pre-exercise. Moreover, as the mechanical hyperalgesia of the tail farthest from the ipsilateral site is reduced, there occurs attenuation of the activation of microglia in the coccygeal cord. Those results suggested the possibility that the exercise performed before the onset of chronic pain may prevent the onset of chronic pain associated with hindlimb immobilization.
