TBI Research
What the Research says about TBI’s and Neurofeedback
Neurofeedback is showing great promise as a supportive therapy for those recovering from brain injuries. By helping the brain reorganize and self-regulate, it may improve focus, sleep, mood, and cognitive clarity. While still considered an emerging treatment in research circles, many clients with TBI have experienced meaningful benefits.

| Feature / Benefit | Neurofeedback | Medication | Talk Therapy | Occupational Therapy (OT) |
|---|---|---|---|---|
| How it Works | Trains dysregulated brainwave patterns back toward healthy function | Manages symptoms (e.g., pain, mood, attention) | Processes trauma, emotions, and coping strategies | Restores daily functioning, coordination, and independence |
| Evidence-Based for TBI | ✔ Yes – especially effective in mild to moderate TBI | ✔ Yes – widely used for symptom management | ✔ Yes – useful for emotional and psychological impact | ✔ Yes – key in functional recovery |
| Non-Invasive | ✔ Yes | ✘ No – chemical intervention | ✔ Yes | ✔ Yes |
| Side Effects | Minimal to none | Possible (e.g., fatigue, nausea, emotional changes) | Minimal | Minimal to none |
| Addresses Root Brain Patterns | ✔ Yes – works directly with brainwave activity | ✘ No – symptom-focused | ✘ No – addresses thoughts and emotions | ✘ No – focuses on physical/cognitive rehab |
| Duration of Benefits | Long-lasting with consistent sessions | Short-term unless ongoing use | Medium to long-term with continued use | Depends on severity and consistency |
| Custom-Tailored | ✔ Yes – based on individual brain maps | ✘ Standardized doses and prescriptions | ✔ Yes – sessions are client-guided | ✔ Yes – based on individual functional needs |
| Supports Brain Healing | ✔ Yes – promotes neuroregulation and plasticity | ✘ Manages symptoms but doesn’t address healing | ✔ Yes – supports emotional adaptation | ✔ Yes – retrains brain and body skills |
| Typical Treatment Duration | 30–40 sessions (can vary) | Ongoing as needed | Weekly sessions over several months | Varies depending on injury severity |

Summary: This pilot RCT with 40 participants with mild-to-moderate TBI compared LORETA neurofeedback to a waitlist control. After 20 sessions, the neurofeedback group showed significant improvements in executive function (measured by the Trail Making Test, p < 0.01, Cohen’s d = 0.72) and mood symptoms (Beck Depression Inventory, p < 0.05), with increased coherence in frontal EEG patterns. Benefits were maintained at a 3-month follow-up.

Why It Supports Neurofeedback: The RCT demonstrates LORETA neurofeedback’s efficacy for cognitive and mood symptoms post-TBI, with neurophysiological evidence of improved brain connectivity.
2) May, G., et al. (2020). "Neurofeedback for Traumatic Brain Injury: A Systematic Review and Meta-Analysis." Brain Injury.
Summary: This systematic review and meta-analysis of 12 studies (including 6 RCTs, 315 participants) evaluated neurofeedback for TBI. Protocols like SMR and alpha/theta training significantly improved cognitive function (SMD = 0.65, p < 0.01) and reduced fatigue and depression symptoms (SMD = 0.58), with effects comparable to cognitive rehabilitation in some trials. The review highlights neurofeedback’s role in normalizing EEG abnormalities post-TBI.

Summary: This article combines a review of 5 studies (n = 92) and case studies on LORETA Z-score neurofeedback for TBI. It reports significant improvements in attention, memory, and headache frequency (p < 0.05, average d = 0.70) after 10–20 sessions, with EEG normalization in frontal and temporal regions. The review suggests LORETA’s precision in targeting TBI-related brain dysregulation.

Summary: This case series and review of 8 studies (n = 156) examined quantitative EEG (QEEG)-guided neurofeedback for TBI. After 20–30 sessions, participants showed significant improvements in verbal memory (Wechsler Memory Scale, p < 0.01) and mood (Hamilton Depression Rating Scale, p < 0.05), with normalized theta/beta ratios. The review supports QEEG-guided protocols for personalized TBI treatment.

Summary: This RCT (n = 60) tested SMR and alpha/theta neurofeedback as an adjunct to standard rehabilitation in moderate TBI patients. After 24 sessions, the neurofeedback group showed significant reductions in post-concussion symptoms (Rivermead Post-Concussion Symptoms Questionnaire, p < 0.001, d = 0.80) and improved sleep quality, with EEG changes in SMR power. Effects persisted at a 6-month follow-up.
