  • Values are mean±SD.

  • * Gait measurements excluding a patient with extreme outliers. Results of tDCS and sham groups are presented in the first and second row, respectively. 95% CIs were obtained from the linear mixed effects models and refer to treatment effects (real vs sham tDCS) in terms of change from baseline.

  • tDCS, transcranial direct current stimulation.
