Traditional neurofeedback, although simpler than other methods, is a straightforward and effective form of treatment. Traditional neurofeedback utilizes the raw data of an EEG detected from 2-4 sensors strategically placed on the scalp. Some examples of traditional neurofeedback include SMR or Sensorimotor Rhythm training, Inhibit/enhance training, and Alpha/Theta training.
SMR training is a linear activity where the client is asked to increase the amplitude of sensorimotor rhythms on the motor strip of the brain. When the client produces SMR amplitudes that rise above a threshold designated by the clinician an audio tone sounds or visual cues brighten. When the amplitudes fall below a threshold the tone gets softer or the visuals dim. This type of neurofeedback has also been adapted to videogame modules for younger aged clients. Over several sessions self-defeating behaviors such as restlessness or inattention begin to remediate. This same process is true for Inhibit/enhance training.

The goal of Alpha/Theta neurofeedback specifically aims to produce Theta waves that are greater in amplitude than Alpha waves. This alpha/theta amplitude ratio has the effect of moving the client into a deeply relaxed state that is an internal experience close to that of the beginning stages of falling asleep. Alpha/Theta training has been an effective therapy for traumatic stress as well as addiction, and typically uses audio feedback tones while the client sits in a comfortable recliner with their eyes closed.
