[forty five]. Twelve people having a remedy-resistant MDD acquired 12 to 24 one particular-hour classes of mixed activity-primarily based SMR or beta neurofeedback and classical alpha-theta in addition to cure as standard.

It truly is click here noteworthy which the sample measurement was justified dependant on the anticipated influence size and essential statistical power. The system included three weekly upregulation periods with feed-back and one more on comply with-up and also a transfer session right after the 1st two feedback periods.
