QEEG Neuro-Imaging and sLORETA Neurofeedback – Research in Traumatic Brain Injuries

QEEG LORETA NEUROFEEDBACK

3D Neurofeedback expands on the capabilities of surface neurofeedback with a full range of new advances, using the next generation of 3D brain imaging and training tools. In the hands of a skilled clinician, it is the ultimate brain training toolkit.
Using a full 19 sensor cap, the clinician is able to train any number of areas together (as opposed to individual surface areas with the more common 2 sensor neurofeedback). By using a medical research database (Z-score) and deep brain source imaging (LoRETA), 3D neurofeedback can directly train entire brain networks; targeting overall electrical activity (amplitude), brain connectivity (coherence), processing speed (phase), and more.
This is made possible by more advanced imaging capability – if you can detect it, you can train it. Better imaging equals better results. Better targeting means better reliability. Training multiple areas at once means less sessions.
For clinicians, being able to see exactly what is going on over the entire brain at all times is a real advantage, and by integrating research software the clinician can map, track, and keep the training entirely up to date.
3D neurofeedback takes more skill and experience to operate, and the equipment required runs at a good twenty times the cost of basic equipment. Hence, sessions usually cost about a third more than for traditional neurofeedback – however one requires far fewer sessions to see results.

LORETA Z-score Neurofeedback-Effectiveness in Rehabilitation of Patients Suffering from Traumatic Brain Injuries

This is a multi-case study involving sixty-seven patients diagnosed with Traumatic Brain Injury (TBI) that were subjected to Z-score neurofeedback
(NFB) therapy. Most of the patients were diagnosed with mild TBI and treated within the first year after brain injury. A few patients were diagnosed
with more severe TBI and treated after one year or later following their head injury incident. Most of the patients complained of headaches and
cognitive problems while some of them also suffered from dizziness and overlapping depression. Those who complained of cognitive problems
were subjected to analysis with computerized cognitive testing (NeuroTrax, Inc.) before and after ten sessions of NFB. During the NFB therapy
the subjective response from patients was collected in order to discern whether or not there was an improvement of their symptoms. In addition,
QEEG maps were completed before each NFB session initiation in order to see an objective improvement of QEEG abnormalities. Subsequent
analysis revealed that 59 out of 67 patients (88%) noticed subjective improvement of their symptoms within 10 sessions of NFB therapy, out of
which most of them reported an improvement after only 1-3 NFB sessions. 54 patients also had an objective improvement of QEEG maps (80%)
manifesting as reduction of excessive beta activity and/or normalization of delta or theta power.
45 patients completed prior and post NFB neurocognitive testing with 34 patients (76%) having significant cognitive enhancement (Global
Cognitive Score increased between 3-30 points). These results are very encouraging and indicate high potential of Z-score LORETA NFB
rehabilitation of patients suffering from TBI.
