NCT07625748

Brief Summary

The goal of this single-blinded, randomized controlled trial is to assess the safety, tolerability, and feasibility of tTIS for children with ASD. The main question it aims to answer is: \- Is tTIS safe, tolerable, and feasible for use for children with autism spectrum disorder? Researchers will compare tTIS group with control group to explore the safety and feasibility of the transcranial electrical stimulation for children with autism. Participants will:

  • tTIS group: undergo 5 days of temporal tTIS.
  • Sham group: undergo 5 days of temporal tTIS without low-frequency envelope. From baseline to 4 weeks after intervention completion, subjects will be followed up regarding clinical symptoms and adverse events:
  • Primary Outcome Measures: Safety and feasibility of tTIS, assessed by adverse events, treatment completion rate, adherence to the stimulation protocol and tolerability.
  • Secondary/Exploratory Outcome Measures: Changes in SRS-2 total scores and other clinical measures related to language, adaptive functioning, and cognition.

Outcome Measures

Primary Outcomes (2)

Study Arms (2)

Intervention group (tTIS)

EXPERIMENTAL

Receive tTIS targeting the anterior middle temporal gyrus, with stimulation frequency of 2040/2000HZ, using battery power supply: voltage 12V, current set at 1.5mA, 6 times/day, 20min/session with 20min intervals between sessions, lasting for 5 days

Device: transcranial Temporal Interference Stimulation

Control group

SHAM COMPARATOR

Receive tTIS targeting the anterior middle temporal gyrus, with stimulation frequency of 2000/2000HZ(without 40Hz envelope compared to tTIS group), using battery power supply: voltage 12V, current set at 1.5mA, 6 times/day, 20min/session with 20min intervals between sessions, lasting for 5 days

Device: transcranial Temporal Interference Stimulation

Interventions

Receive tTIS targeting the anterior middle temporal gyrus with stimulation frequency of 2040/2000HZ, using battery power supply: voltage 12V, current set at 1.5mA, 6 times/day, 20min/session with 20min intervals between sessions, lasting for 5 days.
