Abstract

intorduction: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder associated with disturbances in neural communications, motor control, and balance weakness. Non-invasive brain stimulations like transcranial direct current stimulation (tDCS) are considered minimally invasive methods for improving motor and cognitive functions. However, the alternating type, tACS, which regulates brain wave frequency, has not been studied in an organized manner in autistic children. This study aims to design a protocol to compare the effect of tDCS and tACS on brain functional connectivity and balance in children with ASD. Method: This randomized trial will have three groups. Participants are children aged 8 to 12 with ASD, randomly assigned to: 1. tACS (40 Hz gamma, 1-1.5 mA) with balance exercises. 2. tDCS (1-2 mA) with balance exercises. 3. Control group with balance exercises only. Balance exercises include static and dynamic activities on the Biodex Balance System,conducted in 12 sessions (three sessions/week for four weeks). Assessments include EEG recording to examine Coherence and PLV in the gamma band, Biodex balance indices, and the MABC-2. Results: It will be examined to what extent tACS compared to tDCS can improve brain performance and motor balance. Results are expected to provide a clearer understanding of brain waves' role in improving brain and balance functions, creating a basis for more effective neurorehabilitation interventions. Conclusion: The possible results may show that alternating stimulation, by regulating brain wave frequency, has greater efficiency than direct stimulation. Combining brain intervention with balance training can produce valuable scientific evidence for improving sensory-motor skills in children with ASD.
