Chronic Peripheral neuropathy is a major complication of many clinical and therapeutic agents. Even though, many people try to fine the effective methods to prevent or stop developing it, but currently there is no effective methods found. Recent studies report that the swimming exercise attenuates neuropathic pain that were caused by diabetes. But the neuropathy caused by peripheral nerve injury is still unclear. In the present study, we used the model of Chronic Constrictive Injury(CCI) animal model that are widely used for chronic neuropathic pain. For this study, we made Chronic Constructive Injury(CCI) mouse model with cut and suture the sciatic nerve surgery. And we applied the low intensity of aerobic exercise for 3 days per week and compared the pain avoidance ability and pain bio-markers with no exercise control group. To detect the sensory functions and pain avoidance ability, we used the pain avoidance test with heat withdrawal latency tester and Sensory nerve action potential: SNAP). And we had compared and analyzed the ATF-3 that are known as a pain bio-marker. The results said that the low intensity of aerobic exercise on CCI model group enhance the recovery of Sensory nerve action potential(SNAP) than no exercised control group. Also we could detect the lower expression level of ATF-3 known as a pain bio-marker in the lower exercised group than no exercised control group. And we could detect faster reaction in the low exercised group than no exercise control group in the heat shock reaction(heat withdrawal latency) test. This means that the aerobic exercise group has analgesic effect and has better pain reaction than no exercise control group. We had concluded that the analgesic effect of exercise on the CCI animal model with the ATF-3 expression level and behavior test result. This means that the low intensity of aerobic exercise has beneficial effect on Chronic Constrictive Injury(CCI).
