SENSORIMOTOR POTENTIATION OF MOTOR IMAGINATION AS CNS PLASTICITY ACTIVATOR

Aim - to find out the neurophysiological correlatives of motor imagery after the simulation of the motor pattern. Materials and methods. Monopolar EEG was recorded using EEG recording system Neuron - Spectrum - 4 / VPM at 7 right-handed volunteers aged 18-19 years. EEG was recorded according to the system 10-5 in the projection of the sensorimotor cortex of the left hemisphere during the imagination of two movements in the right hand (flexing the fingers, elbow flexion) before and after 30 seconds of simulation of movement patterns using the rehabilitation device Power Plate. Results. After the simulation of the motor pattern, the imagination of the two types of movement correlated with desynchronization of alpha-, beta- EEG rhythms, increasing the number of leads with the reaction of desynchronization (p<0,01) and reliable differentiation of changes in the power of sensorimotor EEG rhythms at dualtrack imaginary movements, and the accelerated learning of motor imagination. Conclusion. Sensorimotor potentiation helps to find out the neurophysiological correlatives of motor imagery.
