"The importance of language to human development cannot be emphasized enough. It was language, with its tremendous flexibility and richness of meaning, that enabled us to communicate with one another in the first place." (Harari, 2015). 

Language is a fundamental component in child development. When suffering from a so-called language development disorder, communication, language comprehension, vocabulary and language formation or several of these areas are affected. 

In his practice in Munich, the psychologist Gernot Wührer treats, among others, patients with language development disorders. In this interview he reports on how neurofeedback can help. 

Gernot, how did you come to work with speech development disorders? 

I cooperate with a speech therapist who works mainly with children from the autism spectrum as well as children with a migration background who often do not learn the German language properly until kindergarten. This colleague has been integrating neurofeedback into the treatment of her patients in addition to speech therapy for some time. Speech therapy can be very challenging for the children and demand a lot from them - especially when the speech disorder is accompanied by problems with attention, concentration and impulsivity. 

We experience that children with motivational problems as well as children from the spectrum strengthen their cognitive-emotional abilities through neurofeedback. Thus, they also achieve faster progress in speech therapy. The children are more motivated, more concentrated and can engage better in therapy - in individual cases, children have needed up to a year less therapy through the combination of neurofeedback and speech therapy and have also quickly caught up on large developmental delays.  

Language development disorders are a large field. Is neurofeedback indicated equally in all of them? 

It is usually the complex cases and developments for which we additionally recommend neurofeedback, for example if, in addition to speech errors, the understanding of or the relationship to language is also affected. But in general, neurofeedback is a brain training that helps to improve the children's flexibility and performance - everyone can benefit from it. 

The children in my practice are mostly kindergarten age. This is where non-age appropriate language development is usually first noticed, but I also work with school-aged children, adolescents, and adults, especially those with autism spectrum disorders. The problems I observe in practice range from systematic grammatical errors to lack of complex sentences up to problems with language content. Children with autism may also only have limited communication, not speak at all or only be able to make sounds. 

What can neurofeedback do in the therapy of language development disorders? How does it contribute to improvement? 

Neurofeedback, as a concomitant therapy to speech therapy, has a positive effect on speech development disorders in at least three ways. 

First, it strengthens cognitive-emotional conditions and improves parameters like attention and concentration in an implicit and playful way. For example, children who receive accompanying neurofeedback training find the work phases in speech therapy easier. They can work concentrated for a longer time, don't give up as quickly, and also increasingly find joy in it because they don't just have negative experiences with languages, but are increasingly strengthened in their abilities. This is what I would call the non-specific effects of neurofeedback. 

In addition, there are the positive effects that neurofeedback has on the children's everyday life. Family life often calms down a bit, because parents also quickly notice behavioral changes in their children - this can lead to everything from better sleep to longer independent play and less bedwetting. This also eases the burden on parents and raises the quality of life for everyone involved.

Thirdly, neurofeedback also has specific effects on language: for me it is a great success when, in the course of therapy, the children begin to form longer sentences, tell something out of their own motivation or start a conversation. I also notice an increasing verbality, an enlarged vocabulary or differentiated sound formation. Especially if you choose specific electrode positioning for speech in neurofeedback and train there, such results become obvious, while the other two non-specific effects often show up even in the typical initial positions, especially with interhemispheric training. 

What are your experiences with neurofeedback in speech development disorders and what feedback do you receive from patients and parents? 

The children often perceive neurofeedback as an "easy" therapy - they are allowed to come to me and, unlike in speech therapy, have no explicit pressure to speak, but are allowed to watch a movie while exercising their brain - this is a helpful setting for children who have had negative experiences with language. 

I am convinced that they benefit especially  from the interdisciplinary approach when neurofeedback is used alongside speech therapy - and the therapists benefit from a better anamnesis and close observation. Many parents who bring their children to me for neurofeedback pay for this treatment themselves - but they see quick progress and are therefore happy to invest in their children's development and language. In addition, they are normally grateful to have found a therapy option that does not require medication and thus usually has no side effects. 

What is particularly important when using neurofeedback in language development disorders? 

For me, good and sound training as a neurofeedback therapist is central. The treatment of language development disorders goes far beyond the basic positions in neurofeedback. Often the electrode positions have to be fine tuned and it has to be clinically assessed which symptom and which position should be treated first. For this, therapists should already have neurofeedback experience. Furthermore, close observation of the patients is essential - especially if they are not able to communicate verbally, signs of over- and underactivation have to be recognized quickly and the training frequency has to be adjusted. However, from my experience especially young children react very sensitively and clearly to frequency changes already in the session - for changes between sessions, dialogue with parents and other treating therapists is essential!

The Development of the Othmer Method
Neurofeedback in its most advanced form

Neurofeedback has evolved significantly since its discovery in the 1960s, with the growth of entirely new forms of application, as well as an increase in opportunities for use. The so-called ILF neurofeedback, often referred to as the Othmer method, is of outstanding importance because its development has been initiated by the US Scientists Siegfried and Susan Othmer and has been in continuous development for decades. The following article describes the origin of this method from the classical beta/SMR neurofeedback, its change to an effective individual neurofeedback approach, and how this development was systematically driven by the Othmers’ commitment.

The Origin of Neurofeedback

Before the potential of neurofeedback was discovered, it was a purely diagnostic tool to measure and analyse cerebral waves via the EEG. The American psychologist Barry Sterman recorded EEGs to study the activity of the brain in various sleep phases in cats. At some point he discovered a unique pattern in the EEG of these test animals. This ranged from 12 to 15 Hertz and was similar to ‘sleep spindles’, which typically appear while falling asleep. These spindles indicate the brain’s ability to suppress alertness and sensation of external stimuli in order to stabilise and enter deeper phases of sleep. But actually, the cats in Sternman’s experiment were not sleeping. They were relaxed but fully awake, conscious and attentive to external stimuli.

Sterman referred to the discovery of this pattern as ‘sensorimotor rhythm’ (SMR), named after the area on the cerebral cortex where he recorded it using electrodes. He then tried to see if the cats could be trained to produce more of this specific pattern intentionally, using a training that followed an operational conditioning procedure. Whenever SMR appeared in the EEG, the animals were rewarded with food. This approach was in fact successful: the frequency of the SMR increased as well as the associated state of relaxed consciousness. This was the first time that cerebral waves were used to influence the behavior of a living organism.

Initially these findings were not linked to therapeutic use, but by coincidence that soon changed. Barry Sterman experimented with the cats on behalf of NASA to investigate potentially harmful effects of a new rocket fuel on living organisms. Almost all cats suffered an epileptic seizure within a small period of time after being exposed to a certain dose of the fuel chemical — only one group of cats responded differently: epileptic seizures either did not occur at all or there was a time delay to exhibiting a seizure. Those cats were the very same ones which had previously been trained to produce more SMR rhythms. An employee in Sterman’s laboratory was particularly fascinated by this result because of her own clinical history of epileptic seizures which did not respond to medication at all. So she agreed to an experiment, in which her brain was conditioned to produce more specific brain activity and to reach SMR state intentionally. In fact, this significantly reduced the number of her seizures. This self-testing was the first time that neurofeedback was clinically applied to human beings.

Shortly after this successful experiment with Sterman’s employee, more patients with epilepsy were treated with the revolutionary procedure and even more beneficial effects were observed: improved sleep problems, reduction in hyperactive behavior and better ability to focus and concentrate were reported by the subjects. Following this, insomnia and ADHD became additional important indications for neurofeedback training. One pioneer of early research in this area was Joel Lubar, a staff member from Sterman’s Laboratory, who subsequently did a lot of great research on neurofeedback in ADHD.

Frequency Band Training

The process discovered by Barry Sterman is one of what is called today ‘Classical Frequency Band Training’. The electrical waves of cerebral activity seen in the EEG can be divided into six groups, the so-called frequency bands. One of these is Sterman’s SMR, while there are five further frequency bands (see box). Dominant frequency patterns seen in the EEG can be used to estimate the brain’s level of vigilance, as specific arousal levels are associated with frequency bands.

The first neurofeedback applications were primarily just SMR training, but soon developed into beta/SMR training. Clients train to produce fewer frequencies associated with inattentiveness (Theta) and tension (High-Beta) in the EEG. Simultaneously they train to produce more SMR and (Low) Beta Frequencies.

The goal is to enter a relaxed but attentive, focused and aware state and to intensify this state. The feedback reward to clients for showing specific frequencies, is usually a pleasant sound or the appearance of a positive reward symbol. If amplitudes of unwanted frequencies increase, this reward is withdrawn or even replaced by an unpleasant warning sound as an inhibit marker.

Classical Frequency Band Training is based on prescribed rules.  For example which frequencies are inhibited or rewarded is determined prior to the training, on the basis of theoretical considerations. This could be compared to not being able to set equipment in the gym to one’s individual physical conditions but to operate all the machines with the same predetermined weights and adjustments for everyone. This also applies to SCP training (see box), another form of neurofeedback developed alongside German universities and being used with good success in the treatment of epilepsy and AD(H)D. *SCP training is therefore another prescriptive procedure. 

Evolution of the Othmer Method

Frequency Band Training as a prescriptive method, is grounded on the assumption that there are specific desirable as well as undesirable frequencies in the brain’s activity during? cognitive skills training. The definition of those inhibit and reward frequencies are based on theoretical or statistical considerations on what should be the “norm” in the brain’s activity.  At first there was little reason to question those theoretical considerations, especially as impressive results could be achieved with the beta/SMR training. Nowadays, such general definitions on one individual’s brain activity can be doubted - because we are familiar with the concept of neuroplasticity which was not well-known back then.

Dr Siegfried Othmer and his wife Susan Othmer came into contact with neurofeedback as a powerful therapy option for their son – who was autistic - and became enthusiastic about the method. As a neuroscientist, Susan Othmer had an immediate professional interest in neurofeedback — and her husband Siegfried Othmer, a physicist – was the perfect complement for developing solutions for technical requirements. Together they started their own neurofeedback development institution (EEG Spectrum Inc.) in the mid-80s in Los Angeles, which later expanded to include a clinic and the name was changed to EEG Institute.

The Othmers worked with the beta/SMR training first, but they soon developed the first improvement in the procedure. They decided to no longer simply reward exceeding a single threshold level, but to work with the dynamic of the reward frequency band. The clients were now given feedback of their brain activity from an animation in which a bar moved up or down. The bar represents the proportion of Beta/SMR frequencies in the Frequency Bands recorded from the EEG.

Working with dynamic feedback has been made possible by advances in computer technology, which, moreover, could increasingly reflect the EEG signals in ‘real time’, with almost no  delay. Using the dynamic of reward frequency bands as a feedback signal marked the first of many subsequent shifts away from the initial explanatory model because this neurofeedback was no longer based on operant conditioning.

Dear Gunilla, thank you for taking your time today to talk about Neurofeedback. Let`s get start right away: What fascinates you about Neurofeedback?

I think what is so fascinating about Neurofeedback is that we can do so much with so little. We can interact with the brain in a way we couldn’t imagine a few years ago. And it is of course a very interesting therapy option. I am learning every day and even after so many years working with Neurofeedback it is sometimes simply overwhelming what you can achieve with Neurofeedback. So, working with Neurofeedback, especially with ILF Neurofeedback is interesting, challenging and it is inspiring to see the effects. There are no things you cannot repair. There is no stagnation. Neurofeedback is sometimes therapeutically challenging - but in the most positive sense.

How did you get involved in Neurofeedback?

About 10 years ago I was working as a teacher in physical education in Spanish and I met all these kids in school that had problems. So my best friend from childhood, Dr. Bodil Solberg who is the one in Norway working with Neurofeedback, introduced me into it. I was very sceptic at the beginning but I saw the effects and the potential to help children with problems in learning for example. So, I took a closer look and was attending the first Neurofeedback course in Norway in 2009. And after the course there was no doubt. It was clear that Neurofeedback is something I MUST do (laughs). My career as a teacher was left behind. I started to work with Neurofeedback and since then I just couldn’t stop.

You run the Nordic Center of Neurofeedback based in Malmö. What exactly do you do there?

The center essentially does two things: we offer therapy for patients on a private basis and it is a training center where we give courses for professionals who want to learn Neurofeedback.

In my private practice I work with people of all ages. A lot of young people and children but also adults and with different indications. This is my everyday work and I see that during the years there are more and more people who get to know about Neurofeedback and ask for it. We have a high demand. And it's really just incredibly satisfying to see how you can help people with Neurofeedback.

But I also love to teach Neurofeedback and thus contribute that more and more people can benefit from it. Both for therapists by giving them an effective tool and of course by giving more and more people access to it.

So, in 2012 I helped EEG Info Europe to arrange the first international course in Malmö, so then since 2012, every year we now have courses in Malmö. In the first 5 to 6 years, they were international, so we had a lot of attendants coming from all over the world to Malmö for the Neurofeedback courses. And when I got the opportunity to become an official partner of BEE Medic and working as EEG Info Europe lecturer in 2017, since then I’m doing courses in Stockholm and Malmö in Swedish language.

And from this, a very important connection to the Red Cross here in the region has emerged.

Can you tell us more about this connection and the Red Cross working with Neurofeedback? How did the cooperation come about?

With word of mouth. My neighbour, a psychologist, was the chief of the Red Cross in Malmö and she heard about Neurofeedback from me. She said that this is something they must try, because of the many traumatized people they are working with. And in 2014/15 she sent one doctor and one therapist to our Neurofeedback course and started right away to offer Neurofeedback to those who really need help. Of course, this quickly made the circuit. The Red Cross Center in Stockholm heard about it and they sent a couple of people to the next course, which also got very interested in Neurofeedback. And in 2016, they made a pilot study about Neurofeedback and symptoms of PTSD in traumatized refugees with the title “Can Neurofeedback reduce PTSD symptoms in severely traumatized refugees” which was with 5 Persons from 5 countries. It was a small study but it shows the effects and also two books in Swedish refer to this study. Unfortunately, the Red Cross in Malmö is not doing any Neurofeedback anymore, because these persons who attended the course are not working there anymore.

And especially in Sweden and Norway, Neurofeedback is still in its infancy and it needs personal commitment and people to push it forward into the healthcare system. But I am very confident, because there are now many and more institutions working with it. And I am proud that I am a part of this.

There are many other institutions where you have trained health professionals, right?

Yes, of course. Among others we have taught people from the official hospital in Gothenburg and they are doing Neurofeedback now. This year they are starting a study together with a clinic in another town, which will be about PTSD and Neurofeedback. The pandemic has of course delayed everything a bit, but hopefully I can teach in the next course in February 5 other people for this project.

Also, a therapist and chief of the City Mission in Linköping attended the last course in September 2020 and is now offering Neurofeedback at the center. Their clients are women with substance abuse and severe comorbidity. And they want to spread Neurofeedback to other city missions in other towns.

In Stockholm, there is a clinic called WONSA, which means world of no sexual abuse. Last year, we educated a bunch of people who are working there. This is really interesting, because there is a very big need of clinics and people to treat persons with this special trauma and they are very interested of continuing our cooperation and going on with Neurofeedback.

And perhaps a brief summary at this point. Neurofeedback can be really effective therapy module in the treatment of trauma. And via this contacts and commitments Neurofeedback is made accessible to people who really need help and have long suffering behind them. And it is just great that we have Neurofeedback as a tool, which can help them.

What are your personal experiences in treating trauma with Neurofeedback?

Of course, I have an understanding of trauma, but let's be clear: I am not a trauma specialist. I have deep insights because I taught professionals from institutions mentioned above in Neurofeedback. Not especially Neurofeedback for Trauma, but we have seen that this is an indication where our approach can be very useful in the context of an entire therapy process. Trauma has a broad spectrum and it is always important that the clients are in medical care.

When I have clients with trauma, I tell my clients that they also need to have a trauma therapist besides. But to give you a short example: last year a young man was coming for a complex trauma. He was also refugeeing many years ago. He had problems taking the train or a flight, or other situations that involve crowds of people. He made 20 Neurofeedback sessions in spring 2019. After the summer, he came back and told me, that he went on vacation for the first time for many, many years and went with his family to Turkey by plane. For the first time, he was able to take a train without feeling any anxiety. When he was on the plane half away to Turkey, the pilot said that something was wrong with the aircraft, so the plane needed to return all the way back to Copenhagen and even then, he still didn’t feel any anxiety. Many people on the plane got very nervous and he was calming them down. So back in Copenhagen, he flew to Turkey on the next day and was very happy about it. Maybe sometimes Neurofeedback can really relieve from trauma. He is still coming to me now and then and he is feeling very good.

How important is Neurofeedback in Sweden and Norway? I mean, you are very committed to networking, working with institutions who establish Neurofeedback services for people who really need help to cope with trauma, sexual abuse, etc. How well established is it in health care system?

It is not established at all in the health care system. But there are so many upcoming clinics and professionals who start to know about Neurofeedback and hopefully sooner or later we will have it more established. Moreover, there are so many sections in the healthcare, where they don’t have many tools to treat, and they need tools. Also, the treatments for abuse and other kind of abuse like drugs and alcohol, are getting more and more interested in Neurofeedback and that is something, I hope we can further extend our cooperation and commitments in 2021. It is extremely interesting and important, because the idea is, that all kind of abuses have more or less trauma at the base. So if you don’t treat the trauma, you don’t succeed with the abuse treatment. So this is a point of view, which I find very interesting.

What do you think? What role will Neurofeedback play in future?

Hopefully a big role. My intention has been from the very beginning, that this has to be introduced to healthcare systems, maybe it will take time, but it must be in a very professional way. My company is small and my marketing not very big or very loud, because it’s more important that it’s done very professional. It takes more time, but this is the right way to go to a higher level in the healthcare system.

You work with patients on a daily basis and you are also involved internationally as a lecturer for Neurofeedback and you support people who are new in the business. What drives you personally?

I simply can’t stop (laughs). Because every day I find a new challenge. It is extremely interesting and I think the teaching part is the one I am focusing more and more now. I hope that I will find more people in Malmö that could learn Neurofeedback, so that I could lead the patients more over to professionals to do it, then I could focus more on the cooperation with BEE Medic to do more courses and teaching and to go around the world to institutions.

Like the first course in Romania in 2019, right?

Yes. This was actually something very extraordinary. I speak Romanian because I made my studies to become a sports teacher in Romania. So then, when some of the Romanian people were introduced to Neurofeedback and wanted to start courses in Romania, I was asked if I could help to teach there. So me and Bastian Palm went there and it was actually something very nice and extraordinary. We were in the Carpathian mountains and held the course in a very nice place there and this was very, very fun and I was happy that I could do that.

So you can tell it's really an affair of the heart for you to qualify people in Neurofeedback.

Yes, absolutely. I would also like to focus on doing courses online, maybe with self-learning content and so hopefully our cooperation can help me focus more in these things (laughs again).
