CANCER
To the best of our knowledge, the current randomized controlled study is the first to investigate the technique of NF with regard to its effectiveness in a sample of cancer patients in comparison with an already established treatment in the field of psycho-oncology. Furthermore, for the first time, the changes in frequency bands due to training was determined in a large number of patients. There were no changes in subjectively perceived cognitive impairment and fatigue in either the NF therapy or the mindfulness control. Essential due to the high prevalence, all affective symptoms were shown to be significantly reduced due to the therapy, demonstrating the clinical relevance of this investigation. Moreover, it can be concluded that the NF therapy is not inferior to an analogous mindfulness intervention. While there is a need for further research on NF in this area, a clinically relevant benefit may be assumed due to the markedly high standardization and the high level of evidence due to the operationalization.
