Post-stroke Injured Cerebral Cortex: Frequency Analysis of the Desynchronization of Its Sensorimotor Rhythms During Motor Intent
2019
During a motor intent, desynchronization of sensorimotor rhythms of the cerebral cortex takes place. This physiological phenomenon, called event related desynchronization (ERD), is used for the development of Brain Computer Interfaces (BCI) for motor recovery. Stroke survivors suffering complete or partial loss of mobility usually require therapy for motor rehabilitation. The damage of the sensorimotor cortex that follows a stroke can compromise the brain rhythms that encode motor states. Therefore, this study assessed the ERD behavior during movement and motor intent in post-stroke patients.
