Protocol summary

Study aim
General purpose: Investigating the effect of neural modulation on verbal fluency in healthy people Specific purposes: 1- Investigating the effect of neural modulation on the improvement of phonemic verbal fluency skills in healthy people Investigating the effect of neural modulation on the improvement of semantic verbal fluency skills in healthy people.
Design
A clinical trial with a control group, a single intervention, a blind strain, randomized on 30 healthy people. A table of random numbers will be used for randomization.
Settings and conduct
For blinding one strain, when we want to perform unrealistic radiation on the cerebral cortex of people in the control group, we will turn off the light irradiation device and continue our work without the person noticing. The location of the study will be the Brain and Cognitive Laboratory, Faculty of Rehabilitation Sciences, Tabriz University of Medical Sciences.
Participants/Inclusion and exclusion criteria
Entry requirements: 1- Age range 18-40 years 2- General health of the participants 3- Mastery of Persian language Non-entry conditions: 1- History of neurological, psychological diseases and speech and language disorders
Intervention groups
The considered groups include intervention and control groups. People in the intervention group will be exposed to near-infrared light, and the control group will not be exposed to real radiation.
Main outcome variables
1- Phonemic verbal fluency score in healthy people before and after the intervention 2-Semantic verbal fluency score in healthy people before and after the intervention

Sample size

Randomization (investigator's opinion)
Randomized
Randomization description
The participants will be divided into two intervention and control groups by a simple random assignment method, and we will use the random number table tool for this.
Blinding (investigator's opinion)
Single blinded
Blinding description
For blinding of one strain, after people are placed in the intervention and control groups, we will not tell them which group they are in, and the near-infrared light radiation is performed in the intervention group. In the control group, so that the participant does not notice, after one second of radiation, we turn off the device and pretend that radiation is taking place.
