ClinConnect Summary

This study will be carried out as a pilot study in order to optimize and set parameters for a subsequent study that will involve more stroke patients. Stroke patients will be trained to mentally imagine the opening and closing of the hand (hereafter named MI, Motor Imagery). During the training, the patients will receive visual feedback in real time that reflects the neural activity related to motor processes. The NeuroFeedback (NF) will be projected with minimal time delay to maximize the neural learning. This type of brain training with feedback is thought to have significant importance t...
