This study finds that sensory afferent electrostimulation enhances motor function in children with hemiparesis, suggesting improved sensorimotor connectivity through TMS.
Background/Purpose: Children with hemiparesis present with sensory and motor deficits. Our study investigates a noninvasive stimulation method to improve hand function in children with hemiparesis. Sensory Afferent Electrostimulation (SAES) triggers action potentials in afferent nerve fibres, leading to increased sensory afferent input in the sensorimotor regions of the brain. In children with hemiparesis/unilateral cerebral palsy, Transcranial magnetic stimulation (TMS) revealed different types of cortico-spinal reorganization, reduced corticospinal excitability, disrupted intracortical inhibition and facilitation, and aberrant corticospinal tract-dependent sensorimotor functional connectivity. In healthy adults, TMS showed that whole-hand SAES induces increased strength of corticospinal projections and intracortical changes. Our goal is to measure the neuromodulatory effect of SAES using TMS.
