The Sweet Spot for Motor Learning: An fNIRS Study in Children with Congenital Limb Loss

This webinar explores the impact of prosthetic use on motor learning and neural plasticity in children with congenital limb loss, utilizing functional near-infrared spectroscopy(fNIRS) to assess changes in cortical connectivity and efficiency. The webinar covers preliminary results of an innovative study using an 8-week prosthetic home training program to track short-term cortical changes associated to motor learning. Participants engaged in structured tasks while fNIRS measured hemodynamic responses in the primary motor cortex (M1), supplementary motor area(SMA), and sensory cortex (S1). Post-training, interhemispheric connectivity strength doubled, with notable increases in the SMA and pre-motor cortex, regions critical for motor planning and execution. Additionally, global neural efficiency increased by 13%, approaching the optimal 15% connection density threshold, indicating improved synaptic efficiency and reduced metabolic cost in neuraltransmission. These findings provide quantifiable evidence of use-dependent neuroplasticity,supporting the integration of prosthetic training with neuroimaging-based assessments to enhancerehabilitation strategies in children with limb loss.
