    Hello. Maybee you must deeper research, what is FFR. then you will see, that ELF is a very useful aparatus and not only a placebo, sa you say.
    Here you can find some interesting things:

      Dear Dusan,

      this article has zero reliable sources about anything other than the “response to complex auditory stimuli” I already dealt with in the article above.

    This is really interesting and thank you for this Marian.
    Do you know Halo sport ? (https://www.haloneuro.com/).
    It is a headset which optimized connections between brain and muscles.
    I would love to read some tests about Halo sport because it is the actual big thing for athletes.

    Thank you Marian

      Thanks for your comment Jérémie. I didn’t know about the Halo but it looks intriguing. I will inquire them to hopefully get a test device.

    Thank you for this article It is really helpful. I am in search for the holly grail easy to use at home device and came across the Brainlink http://o.macrotellect.com what are your thoughts on this? I also wondered about the more famous Muse http://www.choosemuse.com.
    I would love to get your input on these.
    Thank you.

    Dear Ms Sauter,
    I was happy to find your article about elf. I understand that your evaluations are scientifically driven. You elaborated what seems to be contradictory within how elf supposedly is able to affect the brain using a certain technology and the scientific facts about the functionality of the brain, respectively particular parts/areas of the brain.
    I would appreciate it to read more about concrete results of tests you have carried out with test persons using electroencephalogram recordings. I personally can very well imagine that even very low energy magnet impulse can affect the brain. I do meditation using theta waves over headphone at quiet level.
    I do not own an elf device or have any experience with it. But I would consider to get one for myself if it works.
    I hope I was able to express my thoughts in an understandable way.

    Best regards.

      Dear Thomas,

      thank you very much for your comment on this. I did not report results so far, because I haven’t carried out any tests yet. I can do behavioural tests soon. The problem when combining EEG with the ELF emmit is, that I can never be sure whether my signals reflect the signals coming from the brain or the signals coming directly from the brain. Fixing this problem computationally is not trivial so it is pretty time-intensive and I don’t have that much free time at the moment. However, I can start off with some behavioural tests soon.

      Best wishes,
      Marian

    While I am thankful for the theoretical review, I think this review would be a lot more useful for skeptics if it was backed up with actual testing, especially considering this is the first review that pops up on the ELF emmit when searching the web. Being a neuroscience researcher, you probably have the knowledge and the equipment available to help the layperson make an educated decision.

    Other people claim that their doctors could actually *see* its effect on EEG by comparing the graphing while using the ELF vs not using it, but I haven’t seen actual results. It’d be interesting to see that.

    If you’re interested in doing a more in-depth analisys, maybe reach out to the ELF team? I’m sure they’d love a scientifically backed review. I read somewhere that they’ve been approached by Yale to develop other programs.

    Thanks for the knowledge sharing session! I learned quite a bit reading this.

    • msauter says:

      Hi Milo, thanks for your comment!

      I couldn’t agree more with you, testing would be a major improvement to this article. I have already reached out to the ELF team and they were quite cooperative and sent me a review device. The issue with combining the ELF with EEG is the following: When you read the “brain activity” from the EEG, you can never be sure whether it’s actually brain activity or you are picking up the signal DIRECTLY from the ELF device. There are computational approaches for solving this (as we have the same dilemma with transcranial magnetic stimulation) but these rely on exact knowledge of the stimulation parameters (frequency, intensity, stimulation pattern) which the ELF team is not willing to disclose. I am trying to solve this and will come back to you.

      Best wishes,
      Marian

    Hi Marian,
    Have you already started with the test? I would be most interested in their claim to provide a good and deep sleep. As an insomniac for over 25 years I would do about anything to get a regular good sleep instead of the lousy 4-5 hours I get every Night.
    Best wishes,
    Arianne

    Dear Marian, thank you for taking the time to put together the data and produce the video. Although you didn’t carry out actual testing, there seems to be evidence that it does nothing but fill the pockets of the marketers.
    I have actually tested the ELF emmit in conjunction with a Muse. Which is a setup I could afford, not having access to actual lab equipment, ie EEG machinery. I ran multiple meditation sessions with and without the device to compare Muse recordings that are supposed to reflect brain activity. No difference measured.
    Now that you have a test device, did you measure the output directly using an EMF meter? That would be an interesting start.
    All the best,
    Marc

    Hi Marian, I have bought a device and my own daughter has ADD, we have started to use the device in school and she has made a complete turn around with regards to focus. Since she is 6 years old she will not believe it works, so there can not be a placebo effect. She does what she is asked to do, that being colour this picture in or what is this animals name etc. It has been 1 month now and even the teacher including the occupational therapist can not believe what major change has occurred. To make sure the Elf Emmit works I took it to a neurofeedback specialist where we used EEG for reading and put the Elf Emmit on. As soon as it is switched on, her brain waves started to focus better, she has high beta and low alpha, and the Elf Emmit causes these brain waves to resonate within more normal acceptable ranges. Alpha is required for focus and attention, when we switch it on that specific brain wave starts to resonate at around 10Hz. I know people think this is snake oil, but I can see the difference it makes. Hope this help with a more concrete scientific reply. Dr. Friedrich

    Hi Marian, nice article. This ELF device is doubting me too, as to I want to make a research for reducing anxiety in surgery.

    I use binaural beats and it has proven with many research before to reduce anxiety.
    What confuses me I never heard the use of PEMS/PEMFT for reducing anxiety and performing FFR. Instead, FFR is a result of binaural beats.

    When I’m trying to search any relevant studies about PEMS, they all related for something else, quite strange but seems like promising, PEMT has an effect on cellular of bone healing, some claim about pain and inflammation. Not sure because I’ve not read the articles yet.

    But yes overall I agree with you that this ELF device probably is wrong to manipulate brain mental state. I believe binaural beats is better solution for that.

  12. Rudy A. says:

    Thank you for this very interesting article and for writing in such an approachable manner. I initially came across this article only to confirm that the EE product was not legitimate, but continued reading to see the science which debunked the company’s claims.

  13. W Fadel says:

    Hello Marian,

    Is it not possible to create an isolated EEG baseline prior to using the ELF device and another one with the ELF device. If you had these two snapshots, I imagine that we could identify the differences before and after? I am curious about the device and I am unable to find any substantive research trials for it.

    I look forward to your reply

    I just got one about a week ago and I really like it. Re: sleep – I have been sleeping really well and I have amazing dreams. Can’t say much about the improved concentration, but the stress relief seemed to work today when I got some very upsetting news at work. I put it on and was able to calm down and finish writing the lecture I was working on. I don’t know if it works because I think it works, but I seem to be getting good results. After reading this I’d say, “go figure”. I see how I feel in another week ;-D Thanks much for this!!

    The ELF device is an extremely simple device. It it literally a single wire coil and no other circuitry; basic headphones are more complicated. The frequency and pattern will be simply determined attaching headphone wires to an oscilloscope and running the app. In terms of intensity, that will be determined by the audio amp in the device you are plugging it into. If you so desire, you can listen to the patterns with standard headphones. The main problem with that is the app is unreliable, on my phone it seems to pause after a single loop of the pattern.

    Dear Marian,

    I am not a very knowledgeable person when it comes to science. But I would like to thank you for taking time into testing this kind of device and give a real, honest, scientific opinion on it. The world is full of fraudsters trying to take advantage of peoples weaknesses, I’m sorry but that’s how I see these kind of products. We as people, constantly suffer and constantly look for solutions for our problems, these kind of devices seem like candy and with all the complex marketing behind them they seem very genuine. We need the help of more scientist to debunk these things.
    I would like to ask you for an opinion on this device https://thetouchpointsolution.com/. The scientific opinion as the marketing one looks to good to be true. I was actually considering purchasing it for a suffering relative. But I am afraid that is just a fraud and it will just cause more misery.

    Thank you again
    Mark

    Hi Marion
    Thanks for an interesting and informative article on this device. On the advice of my neurologist I recently purchased a Cefaly TENS device in the hope that it might help me overcome chronic pain sensitisation syndrome which I unfortunately developed after an initially misdiagnosed High Flow Fast Flow Spontaneous CSF leak. The leak itself caused many issues including extreme head, facial and neck pain. After 18 months of misdiagnosis and then numerous invasive diagnostics and treatment attempts it has now finally been patched but I have been left with a number of neurological complications including 24/7/365 severe head and face pain. I’d love to hear any perspectives you have on the Cefaly machine and also look forward to your blind study results of the EE. As the pain also compromises my sleep I’m keen to know of any devices that may assist with that, deepen my meditation practice and assist with focus/concentration and memory as that has also been compromised.
    Thanks again!
    Agneta

      Hi Agneta,

      I am sorry for your situation and I hope you get better soon. I do not know much about migraines but the device itself sounds promising. It’s a very goody sign that they link scientific studies which support their claims so I think that there’s at least a good chance that the device will help you lessen the symptoms you experience.

      I wish you all the best!

      Marian
