[Purpose] This study was conducted to investigate the effect of balance and gait training on the recovery 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) protein expression, using western blot analysis. [Results] In the result of the pole test, Groups III and IV showed significantly 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.
[目的] 本研究旨在探讨平衡和步态训练对帕金森病动物模型运动功能恢复的影响。[对象与方法] 总共40只小鼠被随机分为四组,每组10只:第一组为正常组;第二组为帕金森病组且不进行训练;第三组为帕金森病组且进行平衡训练;第四组为帕金森病组且进行步态训练。通过给第二至四组动物注射MPTP诱导帕金森病。第三组和第四组每周训练5天,每天训练1次,共训练4周。通过杆试验和旷场试验进行神经行为学评估。采用蛋白质免疫印迹分析,通过TH(酪氨酸羟化酶)蛋白表达进行免疫学评估。[结果] 在杆试验结果中,第三组和第四组的运动功能恢复明显优于第二组。旷场试验结果也表明,第三组和第四组的运动功能恢复明显优于第二组,且第四组的运动功能恢复明显优于第三组。通过蛋白质免疫印迹分析,我们确定纹状体中TH蛋白的表达在第一组中最高,其次是第三组和第四组,而第二组纹状体中TH蛋白的表达最低。[结论] 本研究结果表明,平衡和步态训练对MPTP诱导的帕金森病动物模型的运动功能恢复有效,且步态训练比平衡训练更有效。
