IRCT20220216054035N1 IRCT 2022-09-24 Shahid Beheshti University of Medical Sciences Comparison the effect of unihemispheric concurrent dual-Site transcranial direct Current stimulation of primary motor and dorsolateral prefrontal cortices with stimulation of primary motor cortex on postural control of older adult with and without cognitive task Comparison the effect of unihemispheric concurrent dual-Site transcranial direct Current stimulation of primary motor and dorsolateral prefrontal cortices with stimulation of primary motor cortex on postural control of older adult with and without cognitive task 2022-10-12 anticipated 27 Complete https://irct.ir/trial/65636 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Used, Assignment: Crossover, Purpose: Treatment, Randomization description: Assessment of static balance is simple randomization. First chose from two sealed envelopes that decide their standing that will be with or without cognitive activity then intervention is on simple randomization thus choosing their intervention method than chose from three envelopes that contain one of three interventions include sham, primary motor cortex (M1) stimulation and, M1-dorsolateral prefrontal cortex (DLPFC) stimulation.After intervention assessment of static balance is simple randomization, Blinding description: We will explain about intervention to participants but they will not aware what type of intervention they will receive in each session. N/A Elderly stability. Intervention 1: Control group: electrode will be like M1 stimulation but device would be off after 60 seconds. 60 second is a reliable stimulation for sham due to the fact that transcranial direct current stimulation( tDCS) effect will be forgotten after one minute. Intervention 2: Intervention group: M1 stimulation , using one tDCS device anode electrode would be placed at M1 and cathode would be placed at supraorbital region. Intervention 3: Intervention group: concurrent dual-Site of M1-DLPFC, 2 tDCS devices will be used. in left hemisphere anode electrode of one device would be placed at M1 and on the other side anode electrode would be placed at DLPFC and cathode electrode for both devices would be placed at opposite side supraorbital region. Yes - There is a plan to make this available What will be shared: All of this study data could be shared after making it unrecognizable. When: Data would be shared one month after publication. To whom: This data only assessable for academic researchers. Conditions: There is no specific qualification for using this study data.
