Abstract

This study is intended to examine the tDCS and Montoya stair task(MST) on sensorimotor recovery and glial scar expression in MCAo induced stroke model of rat. To achieve this goal, this study selected 80 SD rats of 8 weeks. The experiment groups were divided them into four groups, and assigned 20 rats to each group. Group I was a experimental control group; GroupII was a tDCS application group after MCAo; Group III was a MST application group after MCAo; Group IV was a tDCS and MST application group after MCAo. In each group, neurological function test measurement, motor behavior test, montoya stair task test, immunohistochemistric finding of GFAP expression finding were analyzed. In motor behavior test, the outcome of group I was significantly difference than the other group, especially from 14days. In montoya stair task test, the outcome of group I was significantly lower than the other group especially, group II were significantly different on 14days and group IV was most significantly difference than the other group. In immunohistochemistric finding, group II, III, IV were decrease GFAP expression on depend on time stream. These results throughout the MCAo due to focal ischemic brain injury rat model four weeks tDCS and MST was applied, when the neurobehavioural, upper extremity function and ability, histopathologic data suggest that sensorimotor function recovery and a positive influence on glial scar decrease and confirmed that.
