IntroductionThere are no well-established biomedical treatments for the core symptoms of autism spectrum disorder (ASD). A small number of studies suggest that repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation technique, may improve clinical and cognitive outcomes in ASD. We describe here the protocol for a funded multicentre randomised controlled clinical trial to investigate whether a course of rTMS to the right temporoparietal junction (rTPJ), which has demonstrated abnormal brain activation in ASD, can improve social communication in adolescents and young adults with ASD.Methods and analysisThis study will evaluate the safety and efficacy of a 4-week course of intermittent theta burst stimulation (iTBS, a variant of rTMS) in ASD. Participants meeting criteria for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition ASD (n=150, aged 14–40 years) will receive 20 sessions of either active iTBS (600 pulses) or sham iTBS (in which a sham coil mimics the sensation of iTBS, but no active stimulation is delivered) to the rTPJ. Participants will undergo a range of clinical, cognitive, epi/genetic, and neurophysiological assessments before and at multiple time points up to 6 months after iTBS. Safety will be assessed via a structured questionnaire and adverse event reporting. The study will be conducted from November 2020 to October 2024.Ethics and disseminationThe study was approved by the Human Research Ethics Committee of Monash Health (Melbourne, Australia) under Australia’s National Mutual Acceptance scheme. The trial will be conducted according to Good Clinical Practice, and findings will be written up for scholarly publication.Trial registration numberAustralian New Zealand Clinical Trials Registry (ACTRN12620000890932).

Abstract Background Children with autism spectrum disorder (ASD) are almost universally delayed in the acquisition of spoken language as primary means of communication so they tend to have restricted outcomes in terms of independence and integration. Transcranial magnetic stimulation (TMS) is a promising, emerging tool for the study (study and modulate excitability and plasticity, applied in single pulses to investigate corticospinal excitability, pairs of pulses to study intracortical inhibition and facilitation) and potential treatment of ASD. The purpose of this study is to evaluate the role of repetitive TMS in language progress in children with ASD. Results There was a statistically significant clinical improvement in patients receiving active TMS (group I) comparing baseline Childhood Autism Rating Scale (CARS) assessment and after treatment (P ≤ 0.05). There was mild improvement with no significant difference between the patients receiving active TMS (group I) and those of sham TMS (group II), and both groups received language therapy as regard post-treatment CARS. There was significant difference in improvement between the two groups according to eye contact (P ≤ 0.05). There was significant improvement in response to examiner (P ≤ 0.05). There was mild improvement with no statistically significant difference in attention between the two groups. There was significant difference in improvement between the two groups according to active expressive language. There was no statistically significant difference in passive vocabulary between the two groups. Conclusion Repetitive transcranial magnetic stimulation (rTMS) over left inferior frontal gyrus may be a safe and effective way of improving language of ASD. The joint application of rTMS and standard language therapy may lead to more rapid improvement in the language progress of children with ASD.
