“…10 Several studies indicate that MI training in combination with NF can indeed induce positive changes at behavioral, functional, and structural levels. [11][12][13][14][15] At least 1 study provides clear evidence that functional changes are more pronounced when MI is combined with NF as compared with MI without NF. 16 Moreover, concurrent acquisition of electroencephalogram (EEG) NF and functional magnetic resonance imaging (fMRI) in healthy individuals validated systematic NF effects on cortical activation patterns.…”

Motor imagery (MI) with neurofeedback has been suggested as promising for motor recovery after stroke. Evidence suggests that regular training facilitates compensatory plasticity, but frequent training is difficult to integrate into everyday life. Using a wireless electroencephalogram (EEG) system, we implemented a frequent and efficient neurofeedback training at the patients' home. Aiming to overcome maladaptive changes in cortical lateralization patterns we presented a visual feedback, representing the degree of contralateral sensorimotor cortical activity and the degree of sensorimotor cortex lateralization. Three stroke patients practiced every other day, over a period of 4 weeks. Training-related changes were evaluated on behavioral, functional, and structural levels. All 3 patients indicated that they enjoyed the training and were highly motivated throughout the entire training regime. EEG activity induced by MI of the affected hand became more lateralized over the course of training in all three patients. The patient with a significant functional change also showed increased white matter integrity as revealed by diffusion tensor imaging, and a substantial clinical improvement of upper limb motor functions. Our study provides evidence that regular, home-based practice of MI neurofeedback has the potential to facilitate cortical reorganization and may also increase associated improvements of upper limb motor function in chronic stroke patients.

“…Some authors, however, suggest that it could be based on rewardbased learning (Johnston et al 2010;May et al 2013). NFB has been successfully applied in treating a variety of neurological and psychological disorders as well as symptoms of traumatic and non-traumatic brain injury (Arns et al 2014;Coben et al 2009;Sterman and Egner 2006;Keller 2001;Wing 2001;Shindo et al 2011). Keller (2001) demonstrated that patients suffering from a mild closed head injury were able to increase their betaactivity with NFB.…”

Some severely brain injured patients remain unresponsive, only showing reflex movements without any response to command. This syndrome has been named unresponsive wakefulness syndrome (UWS). The objective of the present study was to determine whether UWS patients are able to alter their brain activity using neurofeedback (NFB) technique. A small sample of three patients received a daily session of NFB for 3 weeks. We applied the ratio of theta and beta amplitudes as a feedback variable. Using an automatic threshold function, patients heard their favourite music whenever their theta/beta ratio dropped below the threshold. Changes in awareness were assessed weekly with the JFK Coma Recovery Scale-Revised for each treatment week, as well as 3 weeks before and after NFB. Two patients showed a decrease in their theta/beta ratio and theta-amplitudes during this period. The third patient showed no systematic changes in his EEG activity. The results of our study provide the first evidence that NFB can be used in patients in a state of unresponsive wakefulness.

“…Thus, studies using these methods are capable of measuring brain activity even while the subject is standing or walking [11][12][13]. Neurofeedback training using fNIRS and EEG are currently under development [14,15]. The studies of brain activity during the observation, imagery, and execution of actions using fNIRS and EEG will contribute directly to the development of more effective neurofeedback training.…”

Effects of neurofeedback training with an electroencephalogram-based Brainâ€“Computer Interface for hand paralysis in patients with chronic stroke: A preliminary case series study

Abstract: Brain-computer interface training appears to have yielded some improvement in motor function and brain plasticity. Further controlled research is needed to clarify the role of the brain-computer interface system.
