Study of Neurophysiological Markers of Motor Recovery in Post-stroke Patients.

The aim of the study was to explore potential pathways for recovery and adaptation of neural pathways after stroke by examining electrical activity of the brain cortex and cortico-spinal excitability using transcranial magnetic stimulation in people with motor impairment after stroke. Participants in the study performed a simple stimulus-response task with a healthy and a paralysed limb several times at different stages of basic rehabilitation. To compare the data, a group of healthy volunteers took part in a similar experiment. Investigators recorded cortical activity using electroencephalography and muscle activity using electromyography. After the stimulus-response task, investigators also carried out a study using transcranial magnetic stimulation to assess the integrity of corticospinal connections.
