Case studies have shown that low resolution electromagnetic tomography (LoRETA) neurofeedback is effective for many psychological disorders, but it’s effectiveness for individuals experiencing persistent post-concussive symptoms (PPCS) is uncertain. Individuals with PPCS (n = 7) received an eight-week LoRETA neurofeedback and heart rate variability biofeedback intervention. Change in symptoms, driving simulation performance, electroencephalographic z-score deviations, and heart rate variability were compared to PPCS (n = 9) and healthy (n = 8) control groups. Statistical analyses revealed that the intervention significantly reduced electroencephalographic z-score deviations (p < 0.005) compared to PPCS controls. Additionally, headache, nausea, and dizziness symptoms were reduced in the intervention group (p = 0.003) and the PPCS controls (p = 0.001) compared to healthy controls. Participants responded variably to the intervention, therefore case analyses were considered and revealed that some individuals responded to the intervention while others did not. Future studies with larger populations and longer follow-up times may help evaluate whether there are commonalities between positive responders. |
