Repetitive Transcranial Magnetic Stimulation on Motor Function and Meta-Plasticity in Cerebral Palsy: TMS-EEG Study

2026년 5월 12일 업데이트: Cook Children's Health Care System

6-Hz Primed Low and High-Frequency Repetitive Transcranial Magnetic Stimulation on Motor Function and Meta-Plasticity in Children With Cerebral Palsy: TMS-EEG Study

This project examines the use of repetitive transcranial magnetic stimulation (rTMS) as a therapeutic approach to improve motor function in children with cerebral palsy (CP). By applying 6-Hz primed low and high-frequency rTMS and measuring brain responses through TMS-EEG, the study aims to enhance neural plasticity and motor recovery. The goal is to promote faster rehabilitation and reduce long-term healthcare needs.

연구 개요

상세 설명

Cerebral Palsy (CP) is a neurodevelopmental condition marked by motor impairments that affect both upper and lower limbs. This project investigates the therapeutic benefits, safety, and tolerability of repetitive transcranial magnetic stimulation (rTMS) for improving motor function and meta-plasticity (re-organization) in children with CP. Specifically, the study investigates the effects of 6-Hz primed low and high-frequency rTMS on neural motor function and meta-plasticity, utilizing TMS-EEG as a core method for assessing motor evoked potentials (MEPs) and TMS-evoked potentials (TEPs). Through modulating cortical excitability, the investigators expect that 6-Hz primed low and high-frequency rTMS will improve motor function and generate meta-plasticity in children with CP. This improvement in motor and induced meta-plasticity potentially leads to faster rehabilitation outcomes and reduced need for long-term care, which would benefit both patients and hospital systems by lowering treatment costs and improving resource allocation.

실험적: Intervention Group 1
CP participants in the experiment intervention group 1 will receive rTMS using a figure-of-eight-shaped coil and rTMS stimulator (Nexstim, Finland) targeting the contralesional primary motor cortex. The intervention will consist of 10 sessions, each lasting 20 minutes, spread over four weeks. Each session will begin with priming: 10 minutes of 6-Hz rTMS at 90% of the resting motor threshold, delivered in two trains per minute (5 seconds per train with 25-second intervals between trains), totaling 600 priming pulses. This will be followed immediately by 10 minutes of 1-Hz rTMS at 90% of the resting motor threshold, delivered continuously without interruption, totaling 600 low-frequency pulses.
All participants will undergo an MRI scan prior to the intervention to acquire T1-weighted images. MRI data will be provided by the Cook Children's Radiology Department. MRI scans will be used for neuronavigation.
rTMS is a safe, non-invasive way to map brain activity using gentle magnetic pulses. A small coil is placed near the head to stimulate nerve cells without any pain. This helps us understand how the brain controls movement.
High-density EEG (HD-EEG) is a safe and non-invasive brain imaging technique. It involves placing a cap with small sensors on the child's head to measure the brain's electrical activity. This technique does not send any energy into the brain. The investigators will use the HD-EEG to measure motor-evoked potentials (MEPs) and TMS-evoked potentials (TEPs).
실험적: Intervention Group 2
CP Participants in experiment intervention group 2 will receive rTMS targeting the ipsilesional primary motor cortex. The intervention will consist of 10 sessions, each lasting 20 minutes, spread over four weeks. Each session will start with priming: 10 minutes of 6-Hz rTMS at 90% of the resting motor threshold, delivered in two trains per minute (5 seconds per train with 25-second intervals between trains), totaling 600 priming pulses. This will be followed immediately by 10 minutes of 10 Hz rTMS at 90% of the resting motor threshold, delivered continuously without interruption, totaling 2000 high-frequency pulses.
All participants will undergo an MRI scan prior to the intervention to acquire T1-weighted images. MRI data will be provided by the Cook Children's Radiology Department. MRI scans will be used for neuronavigation.
