Objective : To observe the effects of the treatment of tDCS on left primary motor cortex(L-M1) area on patients with PD.
Design : Intervention study: a randomized controlled trail
in the patients’ homes.
Participants (or Animals, Specimens, Cadavers) :
Three male participants with PD, on-medication, aged 66, 70 and 72 with idiopathic PD who fulfilled the U.K. Parkinson’s Disease Brain Bank criteria.
tDCS treatments for 20 times, 2mA for 20 minutes, anode on L-M1 area, catedode on right shoulders, 5 days of 4 weeks
Main Outcome Measure(s) :
the patients took 2-minutes walk test loaded by cognitive load of the oral calculation during the whole test, the calculation was filled with randomed addition and sutraction in which every number was less than 20.
Results : The study showed that the changes of gait speed, stride length and swing phase were statistically significant and all of these changes occured in the first week. However, there are still a lot of charactraristics showed no statistical significance such as lumbar range of motion, foot strike angle, gait candence and so on. Whereas the oral caculation, during the 2-minutes walk test, neither of the changes of the patients’s accuracies nor of the total quantities changed significantly.
tDCS on left M1 area may be effctive for motor function, instead of the non-motor function, when the patients of PD perform multiple tasks at the same time, and all these changes could be observed from the first week.
