NCT06950437

Brief Summary

The aim of this trial is to evaluate the efficacy and safety of precision neuromodulation in improving language ability in children with autism spectrum disorder (ASD) who also have language development delay. The neuromodulation will be delivered using the accelerated intermittent theta burst stimulation (aiTBS) protocol, targeting the language network in the left superior frontal gyrus (SFG), guided by personalized Brain Functional Sector (pBFS) technology.

Outcome Measures

Primary Outcomes (1)

  • CLAS-TP score change after treatment

    The score changes of combined CLAS-TP (Child Language Assessment Scale - Test for Preschoolers) score at 12-week from baseline. Higher scores mean a better outcome.

    Pre-treatment (baseline), post-treatment (12-week)

Secondary Outcomes (4)

  • CLAS-TP total score change from baseline to follow-up

    Pre-treatment (baseline), post-treatment (12-week), follow-up (24-week)

  • CLAS-TP subscale score change from baseline to follow-up

    Pre-treatment (baseline), post-treatment (12-week), follow-up (24-week)

  • WPPSI language score change from baseline to follow-up

    Pre-treatment (baseline), post-treatment (12-week), follow-up (24-week)

  • ADOS-2 SA score change from baseline to follow-up

    Pre-treatment (baseline), post-treatment (12-week), follow-up (24-week)

Other Outcomes (4)

  • SCQ score change from baseline to follow-up

    Pre-treatment (baseline), post-treatment (12-week), follow-up (24-week)

  • ATEC score change from baseline to follow-up

    Pre-treatment (baseline), post-treatment (12-week), follow-up (24-week)

  • CBCL score change from baseline to follow-up

    Pre-treatment (baseline), post-treatment (12-week), follow-up (24-week)

Sham iTBSDEVICE

Participants will undergo three sham iTBS sessions per day, with 1800 pulses per session, over a 12-week period. Sham stimulation will be delivered through a sham coil with the identical appearance as real coil. Individualized targets will be generated using the pBFS technique.
