<p>The introductory period before a client begins neurofeedback is dependent on the clinician's toolkit. Some clinicians will choose biofeedback modalities to stabilize and better regulate the system before entering neurotherapy. Modalities that are common
    are pEMF stimulation, heart rate variability treatment, and psychotherapy. There is no "one way" to enter neurofeedback and what is of imperative importance is that the clinician understands the brain that they are working on before applying any treatment
    modality. This is of course accomplished through a thorough EEG and QEEG assessment, followed (preferably) by a report wherein the client's symptoms are outlined and understood.</p>
<h4>Impedance Checking Before EEG</h4>
<p>When gathering the EEG, the clinician must be able to discern real data from artifactual data. This topic is covered in the earlier secion on artifacts. Most EEGs have a system of impedance checking that goes along with the amplifier.&nbsp;</p>
<p>Here is a video of impedance checking in the Neurofield system.</p>
