NCT07045584

Brief Summary

The goal of this open-label randomized controlledl trial is to explore the safety and efficacy of conventional transcranial alternating current stimulation (tACS) and transcranial temporal interference stimulation (tTIS) targeting the temporal pole in children with autism spectrum disorder (ASD) in China. The main questions it aims to answer are: \*Can tACS and tTIS safely and effectively improve clinical symptoms in children with autism? Researchers will compare the tACS group and tTIS group with control group to explore the safety, feasibility and efficacy of the transcranial electrical stimulation in children with autism. Participants will:

  • tACS group: undergo 5 days of temporal pole tACS
  • tTIS group:undergo 5 days of temporal pole tTIS
  • Control group: receive routine rehabilitation training during the study period. From baseline to 4 weeks after intervention completion, subjects will be followed up regarding clinical symptoms and adverse reactions:
  • Safety Outcome Measures: adverse events
  • Primary Efficacy Outcome Measures: Social Responsiveness Scale (SRS-2) total scores
  • Other clinical outcome measures related language, adapative function and cognition

Outcome Measures

Primary Outcomes (1)

  • Social Responsiveness Scale, SRS-2

    The SRS-2 is primarily used to assess symptoms associated with ASD. Compared to other autism assessment tools, the SRS-2 stands out for its focus on quantifying the severity of social impairment, with higher scores indicating more autism symptoms and greater social disability.

    Baseline, 4 weeks after completion of 5-day intervention

Secondary Outcomes (7)

  • SRS-2

    Baseline, after completion of 5-day intervention

  • Childhood Autism Rating Scale (CARS)

    Baseline, 4 weeks after completion of 5-day intervention

  • Chinese Communicative Development Inventory, CCDI

    Baseline, 4 weeks after completion of 5-day intervention

  • Peabody Picture Vocabulory Test, PPVT

    Baseline, 4 weeks after completion of 5-day intervention

  • Neuropsychological Assessment for Child, NEPSY-II

    Baseline, 4 weeks after completion of 5-day intervention

  • +2 more secondary outcomes

Other Outcomes (1)

  • Several electroencephalography (EEG) parameters

    Baseline, after completion of 5-day intervention, 4 weeks after completion of 5-day intervention

Study Arms (3)

Intervention group(tACS)

EXPERIMENTAL
