Are ‘Spiral’ Vibration Training Machines A Gimmick?

08th July 2013

pivotal vibration machine in zero gravityTo answer that question, we first need to get clear about why Whole Body Vibration machines were invented and what feature of them makes health benefits possible. Whole Body Vibration machines first became commercially available in Europe in the 90s and were designed to combat the detrimental effects of microgravity during space travel.

How Does Gravity Work Its Wonders?
Scientists have found that it is not just the absence of gravity that causes the health problems suffered by Astronauts, specifically it is the reduction of gravity in the Axial direction. ‘Axial’ means gravity pulling along a line through the body going from the head to the toes eg. when standing upright.

Does this mean that supplementing gravity with Whole Body Vibration only restores health if applied in the Axial direction?

While there is little evidence of benefits from gravity applied in the horizontal direction, there is ample evidence to show that health results from the force of gravity pulling vertically through the axis of the body, not horizontally across the axis of the body.

This has been demonstrated in “bed-rest” studies where test subjects remain horizontal for weeks and months at a time, not even sitting up to eat, bathe or go to the toilet.

In these studies, even though the person is still on Earth, still under a normal amount of gravity they are not experiencing the normal direction of gravity and suffer the same detrimental health consequences as an Astronaut would in the microgravity of space. These changes include balance disorders, muscle loss, bone loss, spinal dysfunction, and cardiovascular dysfunction.

What Does 45 Years Of NASA Research Tell Us?
Dr. Joan Vernikos, author of “The G-Connection – Harness Gravity and Reverse Aging” and one of the scientists in charge of studying the health of Astronauts at NASA for the past 45 years says:

“Gravity is our lifeline; reduced gravity accelerates the aging process.”

horizontal gravity exposureThose negative health effects were not merely a consequence of inactivity. Subjects undertaking intensive cardiovascular exercise while horizontal were not able to completely prevent cardiovascular dysfunction, bone loss and other effects. Dr. Vernikos goes on to say:

“Despite strenuous exercise in space, for several hours every day, loss in bone, muscle, and cardiovascular function happens ten times faster in space than on Earth. Exercise without gravity is not as effective. Gravity pulling in the head-to-toe direction is maximally effective”


What About Vibration Machines?
Where traditional exercise has failed, Whole Body Vibration has succeeded in counteracting the deleterious effects of reduced axial gravity, but as the research shows – only when the Acceleration is sufficient. In the Berlin Bed Rest study (1) researchers found that 8 minutes of Vibration Training with 15G of Acceleration twice a day, 5 days a week (average of 11 min/day) completely prevented loss of bone and muscle strength in people confined to bed for 56 days.

In other words, that 11 minutes of 15G vibration training was equivalent to the amount of gravity exposure a person would ordinarily get in a whole day.
In repeat experiments using the same vibration machine and same exercises, when G-force was reduced to 10G, muscle and bone loss was only partially prevented. When it was further reduced to 5G or less the benefits were reduced by 70-100% ie. low-G vibration was ineffective.

The original Whole Body Vibration machines from the 1990s were powerful, European-made machines capable of producing over 20G’s and with good reason – high G-force works!

In response to the growing popularity of high G-force vibration machines in physical therapy and elite sports, manufacturers in Asia decided to start making vibration machines too. With the majority of machines now coming from Asia and there claiming to be made according to traditional Chinese medicine principles, you could be mistaken for thinking the technology originated there. In reality, however, Asian manufacturers copied the European concept, and for the most part, did a pretty average job of it. Most machines coming from Asia struggle to reach 5G.

What Are ‘Spiral’ Vibration Machines?
vertical g-force exampleThe latest ‘innovation’ from Asia is “Spiral” vibration. In a traditional vibration machine, the force of gravity is primarily directed vertically up through the body in the axial direction.

horizontal g-force exampleIn a Spiral vibration machine the vibration is not directed into the body at all, instead the force is primarily directed horizontally away from the body. When scientists (2) tested a Pivotal, Lineal, and Spiral vibration machine they found the Spiral machine was able to produce 4G in a horizontal direction but only 1G or less in a vertical direction.

Some machines are capable of Spiral vibration plus Pivotal vibration at the same time however even with the addition of some Pivotal vibration the result is still only a few G of vertical acceleration.

Of course, suppliers of Spiral vibration machines were quick to claim the superiority of this vibration method; strength, bone density, lymphatic drainage, whatever you want, ‘Spiral’ will do it better!

Does The Research Support Spiral Vibration?
spiral vibration platformAs an exercise or therapeutic modality Whole Body Vibration is really well supported in scientific research with over 400 papers published. Of those 400+ papers, not one of them supports the use of “Spiral” vibration.

There is no evidence to support the claim that Spiral is ‘better or even comes close to being ‘as good as traditional Pivotal and Lineal vibration. Not a single health benefit has been proven.

Without any logical or scientific reason to expect any benefit from using one, sellers of these low-powered machines resort to using carnival tricks such as showing water being sloshed around in a tube when placed on a vibrating Spiral machine – hoping consumers will forget that their bodies are not hollow empty tubes of water and instead be so entertained by the stunt they buy one.

Not only do Spiral vibration machines provide practically no axial loading to the body the meager amounts of acceleration they do create is directed away from the body into space.

So it seems that rather than helping someone increase their exposure to gravity, Spiral machines come pretty close to duplicating the experience of being in space!

    SilverMink Whole Body Vibration machine provides SPRIAL vibration and has been found to be effective and beneficial to numerous health disorders by Physiotherapists in Australia, nursing homes & retirement villages, special school with severe physical impaired students and individuals with health disorders.
    Please visit http://www.youtube.com/watch?v=vAFedrzKWDs, http://www.saunagem.com.au/testimonials.htm
    The SilverMink WBV machines have benefited people suffering from Multiple Sclerosis, Cerebral Palsy, Lymphedema, poor circulation, osteoporosis, joint or muscle stiffness or pain, muscle weakness, immobility, poor balance, etc.

    We DO NOT offer “carnival tricks” for our demonstration of the spiral vibration with the column of water. Please see and judge for yourself the demonstration at http://www.youtube.com/watch?v=1ytUMHHjlmE
    You can see the cohesive force of the spiral vibration with a vortex formation and not the alleged statement “water being sloshed around in a tube”. This will greatly enhanced the blood and lymphatic circulation as our body water makes a significant fraction of the human body contained in the tissues, the blood, the bones and elsewhere. For numerous health disorders;


    The SilverMink Spiral machine has certainly increased my AP Spine bone density by 11.8% after using the machine. Changes of about 3% are regarded as clinically significant. The DXA Bone Densitometry report was performed by the Endocrinology & Metabolism Center at the Royal Prince Alfred Hospital.

    Hi Bernard,
    Nothing in your post contradicts our article. There is simply no scientific evidence to back up the claims you make. Testimonials and anecdotal stories are not science, and have not been demonstrated under controlled clinical trials. Your website makes all kinds of non-scientific claims, e.g. “restoring chi” and shows exercises for “body slimming” through sitting down in chairs, and by use of a massage belt which was a gimmick from the 70’s. The website also refers to the Silver Mink technology as “proven” throughout, including a reference to being proven to work for astronauts in outer space, but spiral technology is not the same technology as used in the space program, and no vibration technology has been used on astronauts in outer space!

    I dont care whether whether spiral vibration or pivotal & lineal vibration, which is better but
    whether its a black cat or white cat, whichever catches rats is good cat.
    I had a totally torn ACL two years back and I am using knee brace to help me walk and last November I had a heart attack. I spend almost RGT40,000 on therapy.
    My friend introduces me to SILVERMINK for blood circulation and hopefully it can help me.
    I bought it in January 2014. And guess what?? After using Silvermink for three months consistently for 30 minutes each day. I find that I can walk without the help of knee brace and walking stick. And I feel my body getting stronger and now I dont even pant as much as when I first got the heart attack. I am a stroke victim 12 years ago.

    I find Silvermink vibration machine really work and have help me and alot of my friends.

    Everything has its goodness. Some times we need not be too specific in whether clinically demonstrated as long as it work.
    After all, a machine is only to help us, it never says it can cure us.
