Objective: To conduct a preliminary experimental evaluation of the potential efficacy of Flexyx Neurotherapy System (FNS), an innovative electroencephalography (EEG)-based therapy used clinically in the treatment of traumatic brain injury (TBI).
Participants: Twelve people aged 21 to 53 who had experienced mild to moderately severe closed head injury at least 12 months previously and who reported substantial cognitive difficulties after injury, which interfered with their functioning.
Design: Participants were randomly assigned to an immediate treatment group or a wait-list control group and received 25 sessions of FNS treatment. They were assessed at pretreatment, posttreatment, and follow-up with standardized neuropsychological and mood measures.
Results: Comparison of the two groups on outcome measures indicated improvement after treatment for participants' reports of depression, fatigue, and other problematic symptoms, as well as for some measures of cognitive functioning. Most participants experienced meaningful improvement in occupational and social functioning.
Conclusion: On the basis of these results, FNS appears to be a promising new therapy for TBI and merits more extensive evaluation.
