Infralow neurofeedback in the treatment of substance use disorders: a randomized controlled trial
Background: Infralow neurofeedback (ILF-NF) was recently developed as a subtype of traditional, frequency-based neurofeedback that targets cerebral rhythmic activity below 0.5 Hz and improves brain self-regulation. The efficacy of ILF-NF in the treatment of substance use disorder has not yet been evaluated, but clinical evidence suggests that it may prevent relapse by improving functioning in various life domains. The current study aimed to fill this research gap and extend empirical evidence related to this issue. Methods: Ninety-three patients with substance use disorders at an outpatient unit in Norway were randomized to receive 20 sessions (30 minutes each) of ILF-NF training combined with treatment as usual (TAU), or TAU alone. The primary outcome was quality of life post-treatment as an overall measure of functioning. We analyzed between-group differences using Student t tests. Results: We found no significant differences in quality of life between groups. We found similar nonsignificant results for most of the secondary outcome measures, including drug use, sleep, anxiety and depression. Compared to TAU, the ILF-NF + TAU group reported significantly lower restlessness scores post-treatment (mean difference −1.8, 95% confidence interval –3.1 to –0.5; p = 0.006). Limitations: This study was limited by broad inclusion criteria and a lack of placebo control (sham neurofeedback treatment). Conclusion: ILF-NF offered limited additional benefit when combined with TAU, except in the area of restlessness. Future studies could further investigate the relationship between ILF-NF, restlessness and substance use in targeted subpopulations to illuminate relapse mechanisms. Clinical trial registration: ClinicalTrials.gov: NCT03356210.

The effects of alpha conditioning on the habits of four methadone maintained patients were assessed. All four learned some control over alpha acitivity in the 5-week, 10-session training period. The most striking results, however, related to the subjects’ substitution of self-initiated mental states associated with alpha for previously used drug-seeking or self-medicating methods of coping with everyday problem situations. All four subjects reported a decrease in illicit drug usage and an increased feeling of self-control. Verification of improvement in adjustment and drug abuse was shown by counseling reports and narcotic screens from the maintenance program.

Twenty four volunteer college students who were regular drug users were randomly allocated to three training groups of equal size: alpha feedback, EMG feedback and a joked control group. The subjects were unaware of which feedback condition they received and were asked to practise at home during a six month follow up period in order to achieve a relaxed state similar to that experienced during training. No group was successful in retaining gains made in their alpha levels during each session, but the EMG group significantly reduced their muscular activity during training and retained the improvement during follow up. The alpha and joked groups did not greatly improve their EMG during training but at follow up achieved the same levels as the EMG group. There was evidence to suggest that a reduction in drug use among light and medium users was maintained during follow up. Significant and lasting improvements were made by each group in the duration and quality of their sleep and anxiety levels were reduced.
