“…During LZNF training, the z-scores for all targeted metrics are computed in real time and trained in the direction of z = 0. Although limited, research thus far has demonstrated that LZNF produces clinically-meaningful improvements in both symptoms and brain activity for a variety of disorders, including traumatic brain injury (Koberda, 2015a), depression (Koberda et al, 2014b), anxiety (Koberda et al, 2014b;Lambos & Williams, 2015a), addiction (Cannon, Lubar, Sokhadze, & Baldwin, 2008), seizures (Frey & Koberda, 2015;Koberda, 2015b), attention-deficit/hyperactivity disorder (Decker, Roberts, & Green, 2015;Koberda et al, 2014a), autism (Koberda, 2012), cognitive dysfunction (Koberda, 2014b;Lambos & Williams, 2015b), and cerebrovascular accident (Koberda, 2014a). These outcomes were produced after an average of 10 to 20 sessions, which is less than the 30 to 40 sessions generally required for traditional neurofeedback.…”

Introduction: Posttraumatic stress disorder (PTSD) has been linked to abnormalities within three neural networks: default mode (DMN), salience (SN), and central executive (CEN). This study examined the effectiveness of LORETA z-score neurofeedback (LZNF) training for altering current source within these networks and reducing symptoms associated with PTSD. Methods: Twenty-three adults with chronic PTSD were randomly assigned to 15 sessions of either LZNF (n = 12) or heart rate variability biofeedback (HRVB; n = 11). Psychosocial and physiological assessments were completed at baseline and postintervention. Results: The LZNF group showed very large, statistically significant decreases in symptoms on the PTSD Checklist for DSM-V (PCL-5; p = .003, d = 2.09) and Beck Anxiety Inventory (BAI; p = .003, d = 2.13). The HRVB group also showed very large decreases on the PCL-5 (p = .006, d = 1.40) and medium effects on the BAI (p = .018, d = 0.76). Between-group comparisons showed medium to large effects of group type in favor of LZNF (PCL-5 d = 0.57; BAI d = 0.94), although not statistically significant. LZNF Responders (n = 9) demonstrated very large, statistically significant decreases in abnormal z-scores within all targeted networks (DMN p = .012, d = 0.96; SN p = .008, d = 1.32; CEN p = .008, d = 1.33). Conclusion: The positive outcomes of this study provide preliminary evidence to support LZNF training as a specific, effective, and tolerable intervention for adults with chronic PTSD.

“…My clinic has presented other papers showing usefulness of QEEG in other neuropsychiatric conditions, including autistic spectrum disorders, attention deficit hyperactive disorder, chronic pain, depression, anxiety, cerebrovascular disease, and epilepsy. [32][33][34][35][36][37][38] In addition, diagnostic benefits of QEEG were also reported in patients suffering from concussions and TBI. 39 Other authors also reported a correlation between PET imaging and QEEG 40,41 as well as MRI-DTI imaging where a correlation between white matter changes and functional responses were presented.…”

Quantitative electroencephalography (QEEG)-electrical neuroimaging has been underutilized in general neurology practice. Recent advances in computer technology have made this electrophysiological testing relatively inexpensive as well as precise in identifying brain areas with electrical dysfunction related to either traumatic injury or neurodegenerative process. In this article, the author presents 2 cases that can be frequently encountered in every general neurological practice: case of early dementia and traumatic brain injury. The clinical usefulness of QEEG is demonstrated by showing evidence of electrical abnormalities and networks dysfunctions (including an elevation of frontal/temporal delta and theta powers as well as abnormalities in functional connectivity). In addition, the correlation of QEEG and findings from structural imaging technique—magnetic resonance imaging diffusion tensor imaging and another functional imaging—positron emission tomography is presented.

“…This is well exemplified in cases of neuromotor disorders where neurofeedback requires patient engagement to modulate their brain activity patterns associated with movement; implementation of low-resolution EEG tomography neurofeedback (z-score LORETA) in patients with occipital cerebrovascular accident leads to promising improvement in both cognitive and motor functions (Koberda and Stodolska-Koberda, 2014). Similar beneficial effects have been reported for a number of conditions relevant to vocational therapy, from spinal cord injuries to epilepsy (Birbaumer et al, 2009).…”

Brain-computer interface neurofeedback has rapidly become an engaging topic for occupational research at large. Notwithstanding some criticism, research and practice have begun converging on the efficacy of brain-computer interface neurofeedback as a part of holistic interventions in rehabilitation. Yet, its use in vocational contexts has recently blossomed into wider attributes, beyond rehabilitation practice per se, additionally targeting performance enhancements and leadership interventions in healthy individuals. By exploring this emerging scenario, this paper aims to provide an interdisciplinary forum of analysis on the deriving implications for rehabilitation professionals, signaling how these may invite both possible threats for the field and opportunities to engage in novel translational partnerships.
