Testimonial from Chris Kafity

"I have been using Audio-Visual Entrainment (AVE) sessions with two of my clients with Alzheimer’s. They responded so well for 24 hours after gamma 40 Hz, almost as if no dementia, but it faded to nothing. These clients were almost impossible to get to come for sessions. I had them use my Mind Alive DAVID Delight Pro with the viewhole and or multicolor eyesets. After a week, each of their families bought their own devices. They do daily SMR/Beta and Gamma sessions back-to-back, taking a day off here and there. If they pause too many days between sessions, their symptoms worsen. Both clients became less agitated and more cooperative, along with developing improved short-term memory, improved sleep, no incontinence, improved walking/gait, and better appetite. The less-affected client is able to take his two-mile walk and find his way back home, when before AVE he was getting lost. Friends would return him (benefit of a small community). The more-affected client is able to go out for meals with her son again. And best of all, she knows who I am again (she is my best friend...).”

"I am a neurofeedback technician and brain health coach at the Abilene Brain Center in Abilene, Texas. I use the DAVID Delight Pro to beat the odds against my high-risk factors. These include the ApoE 4 gene, COMT SNP, a traumatic brain injury, a hysterectomy, and a high score on the Adverse Childhood Experience (ACE) Survey. Of these risk factors, the high ACE score is the highest risk factor for my brain and body.

Beginning in 2019, I have done a qEEG on myself every January. In 2022, I recognized that my brain was not holding ground. That year, I tried neurofeedback protocols for PTSD. While there were modest gains, in January 2023, I recognized it was time to do something different.
I was familiar with research on 40 Hz Gamma oscillations so, in February 2023, I began using the Mind Alive DAVID Delight Pro. I did the Gamma 3 sessions, training 40 Hz three times a week, and the Gamma 1 session, training 13 to 43.8 Hz twice weekly.

I used the time of my audiovisual training to calm my fear-driven brain by practicing body scans, breathing techniques, and guided meditations. After six months, I did a qEEG on myself.

I used QEEG Pro's sLORETA Source Reconstruction Reports to create a pre- and post-comparison. As I worked on the comparison, I couldn't believe it. There were dramatic improvements in every hertz from 1 to 40. When I showed my comparison to my boss, Dr. Ken Patterson, a medical doctor, he immediately said, "We need to offer this equipment to our patients."

Today, I also use the Cranio-Electro Stimulation (CES) equipment included with the DAVID Delight Pro. I learned to focus by pushing myself into hyper-focus, which is exhausting. The CES equipment allows me to focus with ease. The serotonin produced by the CES is also helpful in relaxing my brain and body.

A pilot study published in 2020 stated that 40 Hz sessions twice a week improved cognition, memory, and mood. The AVE and CES equipment are helping my fear-driven brain to move into a parasympathetic state, allowing me to rest, digest, and restore. For the first time in thirty years, I sleep through the night. Histamine intolerance, an enormous problem, is nearly gone, and I can eat leftovers. I have gained five pounds of muscle. I am stronger in yoga, and I am aerobically more fit in Zumba. CPTSD helped me survive, and today, at 72 years of age, the DAVID Delight Pro is helping me thrive against the odds."

"I have a DAVID Delight Plus (wonderful device) and have used it daily through the pandemic, and even before and after, and it's gotten me through some tough times. The most pleasant session for me is the Mood Booster #1, in the mornings.

I've also used the Energizer session on the morning after a sleepless night, and afterwards I feel as if I'd actually slept after all!  And the Schumann Resonance (Meditate #4) always calms me down when I'm stressed. I think this device may be the best investment I ever made. Thanks for all y'all do!”

We have had conversations with several clinicians about how they use AVE in their offices. You can see the videos here:

"My anxiety is less since I've been using the Oasis Pro 100 Hz setting twice per day. Also, I've been able to go one month without a ketamine treatment when before I could only go 2 or 3 weeks since my mom died earlier in March. I'm looking forward to seeing what else Mind Alive can do for me."

"I have used my DAVID Delight Pro now for over a year and a half. I use it daily, without fail. During this time period I have migrated off all medications. This week I did a Vagus Nerve stimulation and was pleasantly surprised of the clearing of my head even further then my daily meditation entrainment results I usually achieve. By positioning the CES attachments differently on the ear it definitely made a difference in the results felt. I am very pleased with my device and highly recommend it to others."

"This device has really helped me. Especially reducing anxiety. It also helps me focus."


Lee Jones

"I have tried a number of settings on the Oasis Pro. The first night I applied the Sub-delta setting and went to sleep that night, I had the first good dream that I had had in almost a year. That's because this last year I have been under much stress related to changes in health and finances. I believe I had the good dream because this setting on the Oasis Pro may increase endorphins, the brain's natural feel good chemical! I have also applied other settings - alpha, the 100 Hz of course, and the theta setting. The improvements I have had in decreasing anxiety and increasing mood have been extremely effective at all the various settings! I love it! I few times I have combined the 100 Hz on the Oasis Pro with the Mind Alive AVS unit and find that combining AVS with CES certainly does increase the results when they are used together. I am VERY PLEASED with my purchase. Thanks Dave and Mind Alive for making such a wonderful device available!"

"N needed to be inside a hyperbaric oxygen chamber for an hour at a time, several times a week, for months in order to treat his advanced prostate cancer. He used the DAVID Delight Plus to help stay calm and peaceful during the course of the therapy and also at night to relax before bedtime. It helped tremendously!

The customer service is excellent! Thanks to Dave and Carol at Mind Alive for always responding to what we needed."

 "I wanted to share an anecdote that is fitting to the time...I had a 21-year-old male who has a severe phobia of shots...always faints. For his second COVID-19 shot, he did the deep extended relaxer prior to and during his shot and here is what his mother reported:
"Just completed vaccine #2 . He listened to the track you suggested and literally he did not flinch, feel pain, or even remotely feel like fainting. He’s sitting here in the car chatting with us and seems totally fine. 
It was like a miracle just happened. I cannot thank you enough for introducing us to this system. Amazing!!!"

"I bought my DAVID Delight Pro back in 2014. I own a business, and as it comes with the territory, I have lots of stress. During 2014 and 2015, I regularly used my DAVID and downloads of Lloyd Glauberman's various HPP programs as suggested by the Mind Alive website.

My profits more than doubled that year, and I was happy doing it! I also wrote two books. This device really helped change my outlook on life. As is typical with many habits, my DAVID habit was replaced by other demands on my life, and it showed! More stress and less success. Then 2020 happened, so I decided to take myself seriously again. I started to use my DAVID Delight Pro and get my other habits organized to help me focus. Despite the insanity of this year, things are going pretty well.

On a final note, I got the GAMMA session upgrades, and all I can say is WOW! I literally walked around after my first session saying "WOW!" I'm guessing I was a little tense before starting, but 30 minutes later, a totally new perspective!

Thanks to the team at Mind Alive! You have a great product that I'm sure has helped countless people have better lives!

"I just wanted to express my gratitude for the Delight Plus. I have a history of family trauma, plus a head trauma. A lot of stress. I've tried the high Beta, the Schumann, SMR in this device plus CES. I tried a lot of different devices, technologies, and sessions over the years. You name it. I've tried it. Not much luck.

With your high Beta I'd get an effect at first but then it wouldn't work as well over time and then it wouldn't work at all. Anything like SMR or Schumann just made me groggy and stuporous. These, I think, are called immobility/withdrawal responses.

But when I started to use the SMR/Beta in Brain Booster and the Mood Booster 2 in Feeling Better the effects were astounding. Clear headedness, increased sociability, and energy. In the Mood Booster the effects were a kind of relaxation I've been trying to achieve with these kind of alternate devices for years and years. I didn't know a person could feel this way. I don't think I've ever felt this way. (I'm in my early 70's)."

"I have struggled with life-long anxiety due to ACE's (adverse childhood experiences). The very first time I used the Delight Pro I felt better - i.e., more calm and less "reactive". I have continued to improve and feel more at ease than I ever have. My wife and daughter use the Delight Pro for sleep issues and it is the most effective thing they've ever tried.
I also use it to assist with learning new music (I play classical guitar). Specific sessions included are specially designed for just the purpose of improved learning. Cool! This is a truly unique device! I can hardly recommend it more."

"I've been plagued my entire life by anxiety. This year I will be 50 and thought I would be stuck on medication (that didn't solve anything) for the rest of my life. 35 years with a lot of trial and error, medications, and counseling, I found what I believe is the last piece to my puzzle. I truly believe neurofeedback and Audio-Visual Entrainment are the answer. They speak the brain's language. I Love my Delight Pro. My brain is much calmer and I am now in the process of stopping the medications that just put a band-aid on things. I'm not afraid anymore. I can make plans and do things that I thought were lost to me. Thank you!"

Testimonial from Dr Maryna van der Berg, PhD

 "In 1988, at the age of 32, I was injured in a serious motorcar accident. I was in a coma for 42 days. I had broken three neck vertebrae, sustained major brain damage and the doctors believed that I would never be much more than a vegetable. Their prognosis was that I would never again be able to take care of myself needed to be placed in Weskoppies, a psychiatric hospital in Pretoria.

My stepmother intervened and managed to get me into another hospital. She asked individuals as well as international prayer groups to pray for my complete recovery. I started to make a miraculous, if slow, recovery. I have no recollection of this period in my life – my first memories after the accident are of myself learning to walk and write again about nine months after the accident. I spent the next two and a half years in physical and mental rehabilitation. In retrospect, I would say that it took me about seven years before I was a fully functional and fairly confident person again.

My whole life had changed and I suffered from severe depression. I visited the best neurologists, psychiatrists and psychologists available to try cure my depression. The verdict was always the same: they would experiment with pills until they got the best to treat the symptoms. There was no cure. Every year the prescriptions just got lengthier and the drugs heavier. A pill for sleep, pills for mood control, pills to wake up and pills to kill the sadness.

In the end I realized that I was suffering from changes in character. Nobody could offer me any hope of total recovery. I tried alternative treatments such as acupuncture, hypnosis and herbal treatments – to no avail.

At 50 my husband and I retired and moved to the South Coast. I kept researching to find something to help myself. One day, a friend handed me a leaflet advertising John Broome’s Mind Power and an apparatus that stimulates the brain to form new neural pathways and to produce its own neurotransmitters such as serotonin and endorphins. In desperation I phoned John Broome and ordered the apparatus and subliminal CDs. Three weeks later I went to Gauteng to take delivery. John explained the simple way the machine works and how to use the subliminal recordings.

This scientifically proven, cutting-edge technology introduced a new era in my life. For six weeks, on a daily basis, I did the 42 minute Alpha-to-Alpha/Beta session. In the beginning I needed a lot of support and encouragement from my husband, as I was still suffering from severe depression. From the fourth week, I could hardly wait for my daily sessions and after six weeks of daily sessions I was a different person. I reduced my medication under my doctor’s supervision.

For the first time in years I had energy, and my curiosity and sense of humour returned. Due to the subliminal recordings that I listened to daily, my confidence and motivation to have a meaningful life returned. Although I felt like a new person, my memory and concentration was still lacking. I then started treating myself daily using the John Broome SMR/Beta 24-minute program for another six weeks. I also continued using the subliminal music as support.

I decided to study further using correspondence courses. I enrolled for a Masters Degree with the University of Metaphysics in Sedona, Arizona, USA. My thesis was titled "Consciousness''. I continued with a PhD, and at the age of 55, I received my PhD from the University of Arizona. My doctoral thesis was titled "Meditation as Medication''. Today I am an ordained minister with International Metaphysical Ministries, a Pastoral Counseling Psychologist, an accredited Accelerated Learning Practitioner, an EFT Practitioner, and I practice various modalities of Energy Medicine. I believe without my brain machine and the subliminals this would never have been possible.

It is humbling to acknowledge the lives I have touched by using the DAVID LS systems. Over the years, I have treated severe cases of depression, ADD and ADHD successfully. I have also helped people suffering from chronic pain, hypertension, severe stress, sportspeople seeking better performance, as well as people suffering from migraines and sleep disorders.

As I write this testimony, I am suffused with intense gratitude – I am grateful to God for His grace, I am thankful to Dave Siever who has devoted his life to the development and perfection of a device that has such incredible potential, I am grateful to John Broome who is dedicated to improving the lives of people all over South Africa. I am intensely grateful that these remarkable people crossed my path and gave me back my life."

"I just wanted to write a review about the excellent customer service and experience I have received from Michael at for the David Delight Pro.

First, the DAVID Delight Pro has been an amazing device. My neurofeedback therapist said that neurofeedback wouldn't work on me because I was taking a benzodiazepine and indeed, I didn't notice a difference from the neurofeedback. We quit after 3 sessions.

Conversely, I have noticed several differences since I got my DAVID Delight Pro with TruVu glasses. I have felt feelings I hadn't felt for years. I can actually soothe my body. My long-term severe depression is gone. My negative self-talk has radically decreased. I appreciate and enjoy silence more. I see more beauty outside of me. I am more present in the moment. Etc. etc.

Michael has given me lots of helpful information, answered several of my calls and taken many of my questions, and further has been very kind and honest. I find him both generous and a pleasure to work with. It's nice to speak to a businessman and honestly believe he wants what is best for you and I'm on the skeptical side in that department. Further, Michael is not the manufacturer of the DAVID Delight Pro so you can feel comfortable with his speaking openly about other devices as well as The DAVID Delight Pro.

I am very grateful for our conversations and have learned so much.

Thank you, Mike! Thank you Mind machines! And thank you Mind Alive! Their customer service has been excellent as well.

I was not asked nor offered anything to write this review."

“The depth and breadth of Dave’s knowledge about AVE and CES, his passion for this work, his creativity and his commitment to customer service are unparalleled. I got a DAVID Delight for personal use and have since "turned on" many friends. There are many vendors of brain enhancement technology out there, and it’s easy to get lost in the woods for those of us with limited understanding and experience. No worries….Mind Alive is the answer. This is solid, research-based, cutting edge technology and unwavering customer support. My experience with Dave was fantastic. I cannot say enough good about Mind Alive."

"The following is about my experience with the DAVID AVE instruments from my DAVID Paradise XL (purchased in 2002 and still in use), to the DAVID Delight Pro newly purchased, and few DAVID PAL 36s in the middle. Let me begin by stating my experience in biofeedback began in the mid 1980s using EMG for muscle tension. I learned about EEG and went through the training and, years later, was among the first group to become certified. I saw great benefit in biofeedback for a number of problems. I began using this to treat anxiety, depression, ADD, and most typical complaints presented to clinicians. Treatment went well for most patients. However, my biggest complaint with this treatment was the length of time it took to for a patient to receive some benefit. 

Then, by a stroke of luck, another clinician was telling me about AVE and had a DAVID Paradise XL. He specialized in ADHD and would tell me about the changes he noticed in his young patients with the AVE. I tried this “new gadget” and did not think it would amount to much of anything. Well, I was in for the surprise of my life. I felt some things that took me weeks or longer using biofeedback, were quickly resolved with the DAVID. I was hooked and had to have my unit. 

I began using DAVID AVE instruments in 2002, and continued with EEG Biofeedback as well. In my practice I noticed a much quicker response time for those with AVE. Patients seemed to enjoy this more than other treatments, and it was user friendly. I had witnessed such a dramatic success rate that I slowly decreased the usage of EEG and went completely with AVE. I found significant improvements in patients, especially those referred for chronic pain. It seemed to me that what I could typically have a patient experience in one AVE session would have taken about three weeks or more of training with biofeedback. But I do need to make one point perfectly clear. I am in no way putting down biofeedback. I am just commenting on my experience with the DAVID AVE units.

For the past seven years, I have been using AVE exclusively. I am employed at a hospital and am part of the pain management team. I have found that, in most cases, using a sub-delta .5-1 frequency has provided the greatest relief of pain for most patients. I have used AVE for treating tension headaches, Migraines, fibromyalgia, PTSD, stroke patients with paralysis (and actually had success in getting some feeling back to the effected areas), and other psychiatric and physical problems. I believe that there may be endless treatment considerations for AVE.

The reason I titled this, “I don’t believe it!” is due to the average comment a patient tells me, first of all when I explain what AVE is and how it will work, and then, after the first session when they feel the reduction in pain or the state of relaxation. I have also noticed, and have been recording, blood pressure readings before and after sessions. I have consistently noticed a reduction in blood pressure on about 85% of patients. Some patients have made incredible gains, enough so they were able to reduce or stop their medications whether it is for hypertension or pain.

The DAVID AVE products have proven to be exceptionally reliable and, if I have ever experienced a problem, I made a phone call, talked to Dave, or any of the friendly staff, and the problem was fixed. I can not express my amazement in the success of this treatment and my gratitude for producing an instrument that is of such high quality.

Dave, I thank you and my patients thank you."

"I ordered the DAVID a little less than a year ago and have had profound results! I am a wellness facilitator, stillness/meditation instructor and personal development coach. My passion is helping individuals overcome depression and other mind-related limitations to live well. I have been working closely with one of my clients who is using the DAVID to overcome depression. After four months of use, she is ready to stop her depression medication completely!  She has transformed in a number of ways and is almost unrecognizable from the person she was a few months ago. I am a true believer in what this technology can do for humanity!"


Testimonial from Dr. Martha Grout

"We have used the Mind Alive audio-visual stimulation (AVE) devices with every patient who is enrolled in our BrainAdvantage program. This program is a form of neurotherapy which employs blood flow biofeedback to increase the blood supply to the frontal lobes, thereby increasing neural connectivity and improving brain function in all kinds of different conditions, from ADHD to depression and anxiety to traumatic brain injury. Audio-visual entrainment is an important part of the program. We find that it calms both hyperactive children and hyperanxious adults, so that they can then actually participate in the remainder of the 90-minute sessions. In fact, the AVE devices are often prescribed for our patients to take home with them, to help them deal with their severe anxiety and insomnia without having to use drugs. The patients often continue to use the equipment, even after their formal therapy has come to an end, as a non-medication means to help them deal with the every-day stresses of life which they previously found so overwhelming. For the depressed patient who is incapacitated with anxiety, the AVE device has been a godsend – successful in reducing anxiety beyond my wildest expectations. We use primarily the ALERT. Pharmaceuticals may calm anxiety, but at what cost? Brain fog, depression, loss of cognitive abilities are only a few of the side effects that people can experience. The Mind Alive AVE devices leave the pharmaceuticals groaning in the dust. Initially we included AVE because we thought that it would play a small role in some patients. Now we use it on every patient (except those with photic induced seizures) as a hugely significant part of the therapy."


Testimonial from Dr. John Carmichael
BC, Canada

"As you know, I am the approved and designated clinical psychologist to the Royal Canadian Mounted Police in my part of British Columbia and have been so for almost twenty years now. Currently, over 80% of my private practice in clinical psychology is with police officers who most typically present with depression in which accumulated traumatic incidents have played a significant role, or with Post-Traumatic Stress Disorder (PTSD), or with both depression and PTSD. Additionally, it has been my experience that the officers I see have waited until the very last minute to call me so that by the time we meet the symptoms are very marked in both number and intensity and they have been on-going for some considerable time.

My diagnosis and treatment plan continues to be based on a careful assessment: a structured clinical interview which can include the Hamilton Depression Inventory and/or the Clinician Administered PTSD-Scale for DSM-IV; clinical psychophysiological measures including baseline arousal levels, reactivity to stressors, and recovery once stressors are terminated; administration of standardized psychological tests such as the Personality Assessment Inventory and the Trauma Symptom Inventory; and often an interview with the client's spouse–I am nothing if not thorough.

Until recently intervention has included a step-wise combination of psycho-education about the diagnosis, seeing a physician for medical examination and possible medication, relevant recommendations for client's to implement based on research in Health Psychology (for example, increasing aerobic exercise, decreasing the use of stimulants, and sleep hygiene), biofeedback-assisted training in relaxation/self-regulation (autonomic nervous system, relevant muscle systems, and EEG), and appropriate aspects of Cognitive Behavioural Therapy.

I continue to do all of the above.

However, since discovering your DAVID technology about 18 months ago, I now include audio-visual entrainment for all of my police clients with depression and/or PTSD once there is psychophysiological confirmation both that they have mastered diaphragmatic breathing, that they can establish an RSA pattern, and that the entrainment creates desirable changes.

When using the DAVID, generally, we begin with (and most often stay with) frequencies at 10 Hz (although sometimes down as low as 7.8 Hz). Some clients keep the unit for six months before returning it as they no longer have the symptoms they came with, others keep it indefinitely using it daily at first and months later only as symptoms reoccur, and still others continue to use it on a daily basis (two people have done so for 12 months now). Regardless, it is clear that well over 90% of my police clients find the DAVID helpful. Among the most common findings are:

  • A rapid decrease in both autonomic nervous system hyper-arousal/hyper-reactivity and muscle tension (I show clients the changes during their first session with DAVID in my office);
  • A longer and longer duration of these positive effects the more frequently they use the DAVID;
  • A rapid increase in mental calmness and corresponding decrease in "monkey mind" (thoughts all over the place);
  • Rapid improvements in sleep (reduced latency to sleep onset, decreased night waking, and increased sense of restfulness come morning) when they use it at regular bedtime and again if they wake during the night and are unable to fall back asleep within 15 minutes; and
  • What appears to be self-initiated changes in both behaviour and cognitions even before any formal introduction of cognitive behavioural therapy.

The positive effects noted above are even more remarkable to me given the suspicion levels typical of most police officers I see, the significant intensity of symptoms upon presentation, and how long symptoms have persisted. Moreover, as people of action, police officers are pleased to have something they can do to modify symptoms quickly on their own without having to talk at length with me about their childhood or mothers as they mistakenly expect we will be doing."

"I wanted to write and let you know how much I appreciate your products. I have personally used a DAVID since 1994; I recommend them to my clients and to people participating in my EEG Professional Certification Training programs through Stens Corporation.
My initial exposure to Audio-Visual Entrainment (AVE) was through a friend here in Minneapolis. He insisted I try it and, though I must admit to some resistance at first, I quickly found that is was profoundly beneficial. I decided at that time to use the DAVID on a daily or twice daily basis for a minimum of 6 months to develop a thorough, personal understanding of the effects of all the different entrainment sessions included with the device.
I found that my sleep improved and I became much steadier and more resilient in the face of the daily demands of my work. My wife also noticed the changes and encouraged me (strongly, I might add) to continue using the device. I have continued using it regularly since that time.
I should say here that I had previously used many other interventions, most with quite positive results. I experienced more than 100 sessions of EEG biofeedback or neurofeedback, more than 20 years of peripheral biofeedback self-training as part of my work as a biofeedback therapist and nearly 30 years of yoga and meditation practice. I feel I learned and grew from each of these experiences and yet when I began consistently using AVE, I found new levels of growth and development that had previously eluded me.
I would say that the changes I noticed most clearly from AVE were experiences of solidity, stability and balance. I believe that the introduction of such precise timing information into the central nervous system can have highly beneficial effects. I have observed these effects with my clients.
Approximately 95% of my clients use AVE during their work with me and most continue to use the DAVID after they complete neurofeedback training. Clients with migraine headaches find that using the DAVID can often abort a migraine already in progress. Clients with anxiety, depression, seasonal affective disorder (SAD), sleep disorders, chronic pain, ADHD and many other complaints find relief from using the DAVID. I find that instead of needing two neurofeedback sessions per week, clients can get the same results in one session per week if they are regularly using the DAVID at home between sessions.
I have also more recently begun to use the variable frequency OASIS cranial electrical stimulation (CES) device with a limited number of my clients after thoroughly testing it on myself and after an extensive evaluation of the relevant literature. In my limited experience with CES I have found that clients with addiction disorders report reduced cravings. I have also used it with a client with a severe traumatic brain injury and found that he experienced a significant reduction in mood swings, less angry outbursts, better physical balance and improved gait.
Probably the clearest example of my own enthusiasm for your products is that most of my immediate and extended family members own and use either AVE or CES or both for everything from insomnia to memory problems.
I am grateful for the work you have done and have no hesitation recommending your products to everyone who expresses an interest in better health, personal growth, optimum performance or just learning how to relax.
In addition, your contributions to the field of neurotherapy through your support of a variety of research efforts and through your own studies have been instrumental in advancing our understanding of this field of human endeavor. Your efforts in this respect are certainly unique in the field of entrainment equipment manufacturers. It is clear that what you do comes from your heart rather than from a desire for profit."

"I met you briefly last year at the Stens training. I was a healthy skeptic - yet went ahead and bought a thousand dollars worth of your products - the OASIS and the DAVID. In a few words -- worth every penny.

I have used the "Brain Brightening" session after meditating. I felt that the fog had lifted in my brain - more energetic, yet calm and relaxed. As you well said, Dave - "the edge was off..."
I thank you - my family thanks you. DAD is back."

I've taught doctors from 49 States, Canada, New Zealand, Australia, Japan, China, Ireland and the U.K. As such, I am always looking for means of improving CNS function. The method of Chiropractic adjustments that I teach demonstrably improve system wide CNS function...generally producing an increase in alpha, warming of the hands, decrease in EDR, HR, and EMG, along with improved posture and bi-lateral weight scale distribution.
I began performing biofeedback first as an assessment tool to determine what my adjustments were doing...then went on into full scale biofeedback training with the BioIntegrator. However, I found a goodly number of folks who didn't wish to invest in themselves either the time or expense of appropriate biofeedback care...they would come frequently for their adjustment, but just didn't wish to "live consciously" or self-regulate. Herein laid my frustration...until I found the DAVID.
As soon as I had it out of the box, the next patient through the door was one that truly needed to "chill out" her CNS, but was unwilling to commit the time or energy to self-regulate. Knowing her EEG "patterns", I had her place the goggles and headphones on, I briefly explained what I was doing, turned on program #1, and waited...15 minutes later, she emerged with a sigh. I received a telephone call later that evening stating that she couldn't recall remembering when she felt so relaxed...and that she could feel the tension "draining" from her body.
The next client I used the DAVID with EEG hookups from the BioIntegrator...and watched as her brain waves centered in the 12-15 Hz range...exactly as the program said it would. She stated that she felt tension release from her body, and felt the mental fog lift.
The next woman was scheduled for her weekly biofeedback session, but was highly despondent and in tears over an incident at her work. Clearly we weren't going to get much done during her session, so I gave her the option of rescheduling...or, letting me try something new. Previously she had displayed on her EEG a significant amount of beta in the 20 to 40 Hz range. I chose session number 1 and 15 minutes later she was a different person. She too called the office to ask if we could do it again at her next appointment, stating that typically she would have been wound up all evening, not slept and been miserable. Instead she stated that when she left she felt calm and centered, and seemed to "glide" through the rest of her day. Amazing!"


Testimonial from Dr. Frederic Boersma

"It is important to note the difference between acute and chronic pain. Acute pain is usually associated with short-term pain, whereas chronic pain is long-term. Physicians often prescribe medication for acute pain, but this same medication can be detrimental in the management of chronic pain. That is why physicians often do not renew prescriptions for chronic pain patients.

When your body is experiencing pain it creates endorphins, a natural pain killer, to suppress your pain. The body's pain messengers compete with endorphins to the point where the more pain you experience the fewer the endorphins created. Thus, individuals who live with chronic pain usually have fewer endorphins in their body than normal people.
Pain medication suppresses the body's ability to manufacture endorphins so that when pain medication wears off there are few, if any endorphins left, which in turn results in increased pain messages from the body. This circular interactive effect is common in chronic pain patients who depend on medication to manage their discomfort. These people never seem to catch up and keep needing more and more medication to maintain a "normal" style of life.

Dependency on Demerol, Codeine, Percoidean, Morphine and other types of pain medications lead to addictive behaviours. These addictive behaviours are eventually reflected in family interaction which become enmeshed and dysfunctional. The point to remember is that when you do not depend on pain medications your body produces more endorphins, you have more control, and the quality of your life improves.

There are several ways to increase the output of endorphins in your body. One of the most effective is to use relaxation techniques which involve imagery research with the DAVID, in conjunction with supportive psychotherapy, has shown that chronic pain can indeed by controlled by using these procedures. This research indicates that regular use of the DAVID can result in greatly reduced dependency on medication and improvement in quality of rest, which in turn contributes to increased self-esteem, family stability, and reduced suicide ideation. And an overall improvement in the quality of one's life."
