Primary | Verbal Fluency | Goal: Improve in verbal fluency in ASD children between 5 and 12 years. We use D-KEFS (Delis-Kaplan Executive Function System Delis Kaplan Sorting Test), Verbal Fluency Subtest - Category Condition.
Description: The verbal fluency Category test evaluates fluent productivity in the verbal domain by asking participants to generate exemplars belonging to the category animals, and subsequently, boys´ names. Participants were given 60 s to do it. Values: Category scores were based on the average number of items generated in the two categories (animals and boys´names) during 60 s. Time Frame: Baseline (Before treatment) and 1 day Post-treatment (after completing 3 months of intensive speech therapy during tRNS sessions) |
During 3 months of intensive speech therapy during tRNS sessions | |
Primary | Sociability | Goal: Evaluate emphaty with CARS scale in autism spectrum disorder children between 5 and 12 years after tRNS sessions.
CARS (Childhood Autism Rating Scale) by Shopler & Reichler (1971) in Spanish version EVAI (Escala de Valoración de Autismo Infantil) by Leal-Soto, F.; Aguirre, L.P. y Williams, E.E. Description: 15 items in the scale that evaluate: Relating to people, Imitative Behavior, Emotional Response, Body Use, Object Use, Adaptation to Change, Visual Response, Listening Response, Perceptive Response, Fear or Anxiety, Verbal Communication, Non-Verbal Communication, Activity level, Level and consistency of Intellective Relations and General Impressions. Values: The CARS scores range from 15 to 60, with lower scores indicating better outcome. It classifies the child as not autistic (below 30), moderately autistic (30-36.5) or severely autistic (above 36.5) |

Secondary | Ratio Theta/Beta Before tRNS | The purpose of the present study was to determine if the theta/beta ratio, and theta and beta separately, correlate with behavioral parameters, and if these measures discriminate between children a with Autism Spectrum disorder (ASD) and normal gender- and age-matched controls before and after tRNS intervention in ASD children between 5 and 12 years old. | During 3 months of intensive speech therapy during tRNS sessions | |
Secondary | Theta Amplitude in T5 Before tRNS | The purpose of the present study was to determine if the theta/beta ratio, and theta and beta separately, correlate with behavioral parameters, and if these measures discriminate between children a with Autism Spectrum disorder (ASD) and normal gender- and age-matched controls before and after tRNS intervention in ASD children between 5 and 12 years old. | During 3 months of intensive speech therapy during tRNS sessions | |
