Patients received active tPCS for 20 minutes in the first visit and sham stimulation for 20 minutes in the second and were assessed for the levodopa response in the third. Clinical and bradykinesia scoring and gait and tremor analysis were done before and after stimulation\/sham\/levodopa in each visit. Scalp electroencephalography (EEG) was recorded for quantitative analysis during each visit. The interventions were compared between pre- and post-intervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0317167125000307_as3\">\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A significant improvement with levodopa as compared to active and sham tPCS was seen in clinical scores.
