This study investigates the impact of several possible methods (changes within and across the NFT sessions) to identify possible changes of SMR and Gamma on the NFT by using different measures (absolute and relative amplitudes, SMR/Theta, SMR/Beta). Additionally the validity of the NFT was analyzed as well as the effect of using strategies to enhance the power of the frequency bands; electrical activity was measured by EEG. Twenty elderly people, who were split into two groups, completed ten sessions of NFT. While the SMR-group trained the frequency band 12-15 Hz the Gamma-group trained the frequency band 40-43 Hz. At the same time as increasing SMR or Gamma, both groups had to suppress theta and beta. The results showed that SMR measured within the sessions increases over absolute and relative amplitudes as well as over SMR/theta. No changes could be recognized regarding to gamma. At the same time no changes occurred by measuring across the sessions for both SMR and Gamma. Concerning validity of NFT the trainability, independency and interpretability could be confirmed for the SMR-group only, not for the Gamma group. Possible reasons for no effects in the gamma-level could be the design of present study and the number of neurofeedback training sessions. In contradiction to the assumption that the usage of strategies results in enhancing the power of SMR, the usage of strategies resulted in no changes of the power whereas the no usage of strategies resulted in higher power of SMR. Through the results of the present study it can be stated that it is possible to train SMR and to confirm validity for SMR-neurofeedbacktraining.
