Practitioner perspective. This article describes a clinician's own experience, cases or methods. It was not peer reviewed or controlled, so it can be subjective. Read it as practical insight, not as evidence that a treatment works.

- Protocol
- 4-channel Multivariate Proportional (MVP) live z-score training, with asymmetric limits where needed
- Sessions
- 23 (second case)
- Equipment
- BrainMaster live z-score training (ANI z-score DLL); NeuroGuide (QEEG)
Key findings
- Combines all z-scores into one training score; the client's experience stays the same as ordinary neurofeedback
- Separate upper and lower limits were added after a client overshot to a very low-amplitude EEG
- Two cases with before-and-after QEEG maps, including 23 sessions of 4-channel training in a 12-year-old
- The author cautions against training everyone toward the norm; no controls
The practical second half of a two-part series on multichannel live z-score training. During training the client still just watches a video, plays a game or listens to music, while the software combines all available z-scores into a single training score. The author describes one change made after experience with a client: separate upper and lower limits were added after a man with high overall amplitudes overshot to an unusually low-amplitude EEG. Two cases are shown with QEEG maps. In a boy with seizures, four rounds of conventional single-coherence training normalized the targeted links but worsened others, especially delta, while later z-score training normalized coherence more broadly. In a 12-year-old with impulsivity and hyperactivity, maps after 23 sessions of 4-channel training showed most abnormalities resolved. The author cautions that z-scores are not an automatic answer, and that not everyone should be trained toward the norm. He has a financial interest in the equipment maker; the method is patent-pending.
