P 114 - Analysis of eeg signal in a child with hemiparetic cerebral palsy during a motor activity: Case study.

The fundamental characteristic of hemiparetic cerebral palsy is the greater motor impairment on the body side that corresponds to the injured cerebral hemisphere. Hemiparesis usually affects the upper limbs, which can provide significant functional disabilities to this population. The objective of this study was to compare alpha and beta band synchronization and desynchronization during the execution of the task in a game, using the limbs paretic and non-paretic. As a result, observed a synchronization of the alpha band for the movement performed by the paretic limb and a desynchronization using the non-paretic limb. This result may indicate less cortical and physical effort to perform the task using the paretic limb. It is believed that this information can stimulate research with a greater number of volunteers and the more thorough study of brain activity in this population.
