Abstract

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive treatment technique for recovery of movement disorders by altering cortical plasticity. In this research, we studied the effects of low-frequency rTMS on white matter (WM) structural connectivity and clinical parameters in children with cerebral palsy (CP).,Four spastic hemiplegic CP children were randomly divided into experimental and control groups. In the experimental group, at first, 1Hz rTMS treatment was performed 4 days/week for 3 weeks on two hemiplegia patients over a contralesional primary motor cortex (M1). Then, 1Hz rTMS treatment was performed 4 days/week for 3 weeks followed by a 30min occupational therapy (OT). In the control group, two CP children received sham rTMS for 3 weeks and then sham rTMS combined with OT for 3 weeks in the same schedule as the experimental group. Evaluations performed using diffusion tensor imaging (DTI), and clinical measurements of gait performance before and after the treatment. Graph theoretical analysis was used to characterize topological changes of structural connectivity. Our findings demonstrate the 1Hz rTMS is effective in improving motor activity in spastic hemiplegic CP children, and is more effective when combined with OT. © 2018 IEEE.
