Effects of Balance and Gait Training on the Recovery of the Motor Function in an Animal Model of Parkinson’s Disease

Abstract. [Purpose] This study was conducted to investigate the effect of balance and gait training on the recov-ery of the motor function in a Parkinson’s disease animal models. [Subjects and Methods] A total of 40 mice were randomly classified into four groups with 10 in each group: Group I-Normal; Group II-Parkinson’s disease and no training; Group III-Parkinson’s disease and balance training was performed; and Group IV-Parkinson’s disease and gait training. Parkinson’s disease was induced by administration of MPTP to animals in Groups II–IV. Groups III and IV did training once a day, five days a week, for four weeks. Neurobehavioral evaluation was performed through the pole and open-field tests. Immunological evaluation was performed via TH (tyrosine hydroxylase) pro-tein expression, using western blot analysis. [Results] In the result of the pole test, Groups III and IV showed signifi-cantly greater motor function recovery than to Group II. The results of the open-field test also showed that Groups III and IV had significantly greater motor function recovery than to Group II, and Group IV showed significantly greater motor function recovery than to Group III. Using western blot analysis, we determined that the expression of TH protein in the corpus striatum was greatest in group I, followed by Groups III and IV, and that Group II had the lowest TH protein expression in the corpus striatum. [Conclusion] The results of this study showed that balance and gait training were effective at recovering the motor functions of a Parkinson’s disease animal models induced by MPTP, and that gait training was more effective than balance training
