Methods Thirty patients with early Parkinson′s disease were randomly divided into an intervention group (n=15) and a control group (n=15). In addition to routine treatment, both groups were apparently provided with tDCS, though the current intensity for the intervention group was 2mA and that of the control group was zero. Both groups were treated for 20min every day for 5 days in succession. Before and after the treatment, all of the patients were evaluated using the timed up and go test (TUGT) and their gaits were analyzed to determine step velocity, cadence and width. Results Before and after the treatment there were no significant differences between the two groups in terms of average TUGT time, though the average TUGT time had decreased significantly compared with before the treatment. Before the treatment there were no significant differences between the two groups in average step velocity, cadence or width. After the treatment, significant improvements were observed only in the intervention group. The average step width of the intervention group was then significantly bigger than that of the control group.
