IRCT20160131026279N2 IRCT 2019-03-07 Tehran University of Medical Sciences Rehabilitation and tDCS in geriatric speech perception The Effects of Dynamic Spatial Hearing Rehabilitation Combined with Transcranial Electrical Stimulation on Speech Perception in Noise in Elderly Men with Normal Hearing 2019-03-04 anticipated 80 Complete https://irct.ir/trial/37952 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Used, Assignment: Parallel, Purpose: Supportive, Randomization description: Random assign to four equal groups with a Quadruple random blocks method. N/A Auditory processing disorder. Intervention 1: Intervention group 1: receiving dynamic spatial hearing rehabilitation in twelve weeks (two sessions weekly, one hour each) at the center and on a daily basis at home. Intervention 2: Intervention group 2: receiving dynamic spatial hearing rehabilitation and tDCS. Dynamic spatial hearing rehabilitation in twelve weeks (two sessions weekly, one hour each) at the center and on a daily basis at home. For tDSC, the direct current which increases from a 0.5 mA intensity gradually to 2 mA (9 v), is presenting by a pair of carbon-rubber electrodes with a diameter of 21 mm and an area of 3.5 cm² dissolved in salt water, anode/right-cathod/left on the superior temporal gyrus area including planum temporale and auditory cortex (T7 and T8 regions according to the electrodes method 10-20) in three months (In the first two weeks, four sessions a week and then a weekly session), and each session will be presented 20 minutes. Intervention 3: Control group: no intervention. Intervention 4: Sham group: not receiving spatial hearing rehabilitation and is placed in the tDCS sessions of the electrode, but no electrical stimulation is applied.
