David Marcarian

President of Precision Biometrics

David Marcarian, MA, is founder and president of Precision Biometrics which supplies and manufactures the MyoVision sEMG and Thermoglide systems. He was awarded a $450,000 grant from the National Institute of Health to assist the development of the MyoVision with NASA. While at NASA he utilized sEMG to evaluate the ergonomics of various hand controllers to be used in future classified Military aircraft.

Mr. Marcarian holds a bachelor's degree in Physics and a master's in Psychophysiology through the NASA-University Program. His master's thesis, titled “An Electromyographic Analysis of Muscle Fatigue in a Flight Simulation: A Comparison of Isometric and Isotonic Controllers” is still cited by current studies as the most relevant research in the field even though it was published in 1986.

 

He has instructed on sEMG technique for Palmer College of Chiropractic, Parker College, Texas Chiropractic College, Life Chiropractic College West and the Canadian Memorial Chiropractic College. His coursework has been endorsed by every state chiropractic association in the United States that mandates sEMG training, and is a required course in Saskatchewan to perform sEMG testing. He has also personally instructed more than 6,000 chiropractors on proper sEMG technique and practice.

Mr. Marcarian's invention the MyoVision 8000 was featured on ABC World News Tonight (National) with Peter Jennings to illustrate its use as an integral tool of evaluating and designing effective ergonomic keyboards and input devices. The keyboard used by Jodie Foster in the movie “Contact” was designed with input from Mr. Marcarian, and turned into a commercial product through the use of the MyoVision instrument.

His latest invention, the ProformaVision™ is used to help pianists and other musicians in improving performance, and will be integrated into the Cleveland Clinics Hospital (Cleveland, Ohio) as a device for aiding the rehabilitation of stroke victims by utilizing the Piano Keyboard and MyoVision sEMG/Video/MIDI device. The MyoVision 3G Wirefree System used to diagnose soft tissue injury, is now the “Gold Standard” in diagnostic instruments and is featured as the tool of choice in the 2010 edition of the AMA's Medical Text “A Practical Guide to Range of Motion Assessments.”

Professional Background
 
I have an undergraduate degree in Physics, and as an undergraduate went to work at Hewlett Packard, and then one day found an opportunity to do some research at NASA nd got a position there as, believe it or not, as a researcher in their ergonomic lab. And so, I ended up doing a Master's thesis with NASA studying fatigue in the arms of pilots flying, comparing different hand controls used to fly the F-16. From there I wrote, I think I was 26 years old, as a joke, a grant proposal and believe it or not, was awarded a half million dollar grant to develop MyoVision, which is the device that you've seen here today. It's used to measure muscle activity and other physiologic measures. I went from there to getting the grant to IBM's research facility, where I studied the visual system and did work with more ergonomics there which was a lot of fun. And then developed MyoVision under the grant and went off and started a business doing that as a market developed out of the blue.
 
 
 
How he found the Perfect Chair
 

Well, first I evaluated it and looked at it at several different conventions and immediately I was taken by the design, looking at it and thinking "Why didn't I design that?" Mechanically, it puts you in a position that's actually probably the most healthy for the human body, considering the fact that we have forces downward and damaging to our spine all the time. And personally, having a broken neck and I had a broken back, lower back, I saw the value of it for myself personally.

Where it became particularly valuable was when I had a relatively high speed impact as a race car driver. I was doing 152 miles an hour at the actual first impact and had quite the severe whip-lash after this crash. As you can imagine, when you crash at this speed it's not very much fun. But what happened was I reached the point where I was incapable of sitting in a normal chair and I purchased a Human Touch Perfect Chair and set a monitor up so that it was attached and mounted to the wall up high with a keyboard that had a mouse and keyboard combined. I was able to actually do some work, do some things relatively painless.

And so, it changed my life actually. I would have never been able to make it to the point where I was in so much pain all the time in a normal chair that I would have to quit whatever I was trying to do. At the most critical time we were releasing a new product and it was very difficult to do when you're in that much pain. And the Perfect Chair came and it was, it was just a God-send. It changed my life. When you get yourself in that position, if you're having inflammation issues when you put ice directly on your back and you're in that position the ice is significantly more effective because of the forces downward on it so it forces so there are so many ways in which that chair is truly genius in its design, so I also like the way it was constructed. It's so easy to put together and very easy to move around.

 
 
 
Recovering from Surgery: Using the Perfect Chair for post-surgery recovery
 

Well, I purchased one, after getting one myself I purchased one for my best friend who had a very serious hip problem and low back problem, and he's since had surgery for both. He called me two hours after receiving it and putting it together, and 2 hours after was when he woke up because he fell asleep for 2 hours and so it has actually impacted his life dramatically too. Both, at the time to prevent the pain that he was in, to be in that neutral-gravity position where you really don't have the forces downward, and everyone talks about defying gravity and that's what you're basically doing, but also after surgeries, because the after surgery, he could, he would do physical therapy, etc… and it was a needed break from all these forces, and there was no other place he could get more comfortable than in that, than in the Perfect Chair. So it worked extremely well for him in a position where he was actually going through rehabilitation for hip surgery. So it was, ah, it gave him a break from having to put pressure in his hip and it worked really, really well for him, and I've seen that for many, many people and it seems that everyone that gets in it seems to not want to get out of it and so the biggest problem I have having a Perfect Chair is that someone gets in it and I suddenly have a new best friend.

 
 
 
NASA Neutral Posture: How is the Perfect Chair like the zero-gravity chaise developed by NASA?
 

The position you're put in the Perfect Chair is very similar to the position they put astronauts in for take-off, and for that, and the reason is simple. When you're taking off into a flight and you're going into outer space, the forces are so tremendous that it's crucial to have those forces be distributed evenly throughout the entire body, and if you don't and you put pressure in one specific area, it would lead to injury very easily on take-off. The Perfect Chair mimics quite closely, exactly what they have in the cockpit of every space launch device I've seen. So, it's very similar in design and it works in the same manner.

 
 
 
If you could describe the Perfect Chair in one word, what would it be?
 

The chair's perfect. It just is. I really, highly recommend that if you don't have one, get one. It will change your life and it has. Everyone that I've either purchased one for or let use mine, they always either end up buying one or coming over to visit, and I prefer that they not come to visit. So I highly recommend the Perfect Chair, I think that it is truly revolutionary, and I also believe that 5 years from now, everybody will own them.

 
 
 
Serenity Wave Therapy
 

In using the wave in the manner in which it works, it does provide essentially a pump for the spine which allows the cerebral spinal fluid to move but mainly to get the joints to move in a manner, again. This leads to greater health and mobility and mobility is what, we all know that every doctor in the world says, mobility is important for life and health and so, to keep joints moving is really good and that's part of what the chair does for you.

 
 
 
What is Zero Point?
 

When it comes to the Zero Point where you actually reach neutral gravity at zero point with the chair which you actually adjust it to, which isn't necessarily all the way back, that's going to vary based on many different factors, for example, height, weight, the distribution weight of a person's body, and to find that Zero, the fact that you can actually locate that zero point position where literally, everything, all forces are spread evenly about the spine allows the spine, because of the fact that there are no downward forces as that point, it allows the spine to decompress, it allows the joints to open up, which always leads to better health because you have the discs that are then allowed to absorb water and also lubrication occurs but you also go past that, so you can easily go past that zero-gravity point with this, which would sometimes have negative affects, if you're going in the wrong direction, you're going beyond neutral point, but everybody's going to be different. Without the ability to adjust exactly where that neutral point is for you the chair would not work for everybody, but because of the fact that you can set that yourself, then you get to benefit, everybody gets to benefit from the use of the chair.

 
 
 
Beyond Zero
 

We're able to go beyond the Zero point because of the fact the knees go, are curved, and the chair's curved. You do get some inversion at that point when you go beyond the zero point, zero neutral gravity point. You're basically hanging upside down to a certain degree. I have an inversion table myself which I use and which is wonderful but the reality is that for most people A, it's scary and B, if you have blood pressure problems of any kind you really shouldn't do it. This [chair] allows pretty much anyone to create something that approaches that inversion and allows the joints to open up and that opening up of those joints is always valuable for the spine. It's extremely good for your overall spinal health. And it's because of the curve in the chair that it allows you to create that inversion and the opening of the joints.

 
 
 
What Drives You?
 

What drives me? An interest in making sure that those that, one of the major driving forces is a desire to make decisions that are medical decisions when it comes to patients based on objective data so that we have a system that is more evidence-based instead of one where insurance companies dictate what we do, or helping determine when the patient's actually injured or not. It's been, for me, it's been – there's nothing more amazing than to see the value in being able to establish that somebody either is, has an injury or doesn't, and long-term I'm interested in seeing people get well and through being more specific and appropriate with the treatments that are used. The device that I developed is very helpful in doing that. When I saw a person who had a stroke play the piano in about a month, that's about the most incredible experience and all because of the use of the equipment. She needed the feedback and it was necessary to help her to learn how to play, so that's intrinsically valuable for me.

 
 
 
MyoVision: What is MyoVision?
 

There are 2 different areas basically, but MyoVision is a device used to measure muscle activity, and it's been instrumental as a technology in evaluating soft tissue injury which is one of those things that's very, very, very difficult to establish. It's been used and established many court cases as a tool that's valid for evaluating injury. The most recent application, called Proforma Vision, is an off-shoot which is at the Cleveland Clinic now in Cleveland, Ohio, the third largest hospital, number one for cardiac, and it's used for helping people with strokes to rehabilitate. Also to help pianists to be better pianists, so we're using the feedback aspect, combined with video along with muscle activity to help pianist become better at playing and reducing repetitive stress injuries so, it's endorsed by Julliard believe it or not and it's another, a new application that's been a lot of fun.

 
 
 
MyoVision and Chiro: How is MyoVision used in the Chiropractic World?
 

As far as the uses of the MyoVision in the Chiropractic world, one of the biggest problems chiropractors have is showing the invisibles, essentially, showing what's going on inside the body. Showing individuals, patients, that what they do actually works and it's been the most difficult battle for them. MyoVision has been the one tool which has helped them the most because you can show that a patient actually needs care, that a patient has actually been improved by care, and you can track their progress over time and it helps them in terms of marketing. It helps them to show when somebody actually may need a chiropractor because you're actually measuring and seeing what's going on inside the body. The hardest thing for them to explain is what they do and MyoVision makes it so it's extremely easy for them to explain what they do because the machine does that for them essentially. Then the other side is those cases they get where there's injury, the device is used to help evaluate injury and can establish that what they're doing is working and also that there's justification for care. So they're much more protected now, having the device to establish they actually need care. It helps them in terms of being scrutinized by any outside source, like insurers, etc. So it's very valuable to chiropractors in that way also.
