| Outline of Final Research Achievements |
At first, we investigated the effects of a vibratory stimulus on the sole for motor, sensory, and locomotive function using a mouse cast model. The sole vibration increased the ankle dorsiflexion range and active movement of the knee joint, but not passive knee joint motion and sensory threshold. In the second experiments, two minutes left side vibration modulated the pain-related Aδ-fibers sensory thresholds of the right side. In the third experiments, the area of spontaneous inhibitory post-synaptic currents (sIPSCs) enhancement had much wider than that of spontaneous excitatory post-synaptic currents (sEPSCs). In last experiments, we showed noradrenaline had more inhibitory effect for the pinch-evoked sEPSCs enhancement than that of air-puff-evoked sEPSCs enhancement. These results suggested that both quantitative evaluation and intervention-induced improvement can be observed at in vivo patch-clamp methods and behavior ways.
