IRCT20151228025732N79 IRCT 2023-07-30 Tehran University of Medical Sciences The effect of transcranial direct and pulsed current stimulation on motor learning and cortical activity in older adults The effect of transcranial direct and pulsed current stimulation on motor learning and cortical activity in older adults 2023-08-05 anticipated 72 Complete https://irct.ir/trial/70838 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Diagnostic, Randomization description: Based on the random block method with the size of 6 blocks; we will assign 1 to 6 for each block. Then, using the random number table, based on the sample size, 12 units of 6 blocks will be selected so that we consider having 24 people in group (A), 24 people in group (B), and 24 people in group (C). Therefore, we will do block randomization, Blinding description: Blinding of the analyst, the outcome evaluator and the participant (double-blind) is done so that the groups are defined as A, B, and C for the patients and provided to the analyst and the outcome evaluator so they do not know about the grouping method. N/A Movement disorder. Intervention 1: Intervention group 1:In this group, according to the protocol, the direct currents of the transcranial direct current stimulation device will be used for 20 minutes and the intensity of 2 mA in the area of the primary motor cortex (M1). Intervention 2: Intervention group 2: In this group, according to the protocol, the pulse currents of the transcranial pulse current stimulation device will be used for 20 minutes and the intensity of 2 mA with a random frequency between 6 and 10 Hz on the area of the primary motor cortex (M1). Intervention 3: Control group: In this group, transcranial pulsed current stimulation and direct Transcranial direct-current stimulation are randomly used, and the current is automatically cut off after 30 seconds and is only for comparison with the intervention group. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is No more information.
