Rattling Teeth?
jj asks:
My father has just purchased a Power-plate personal for the family and after reading this page I am concerned that it may do us harm?! Is there any reason for me to be alarmed at this stage or would you say that the unit is safe for using 2-3 times a week for 15 mins as they say.
I hopped on it for the first time today and felt my brain rattling against my cranium and my teeth sounding like a machine gun hah! Really enjoyed the massage it gave my lower back
A small amount of vibration working its way into your head is to be expected.
But if its rattling your eyeballs and brain it means the resonance Frequency of your lumbar is being matched.
You do not want that long term.

I had the same question with you.
Probably you dont sit at the proper position while doing the exercises . Please study verywell the posters with the exercise positions.
Be noticed that you can not be aware from shaking your head while exercisig but whith the right position you can reduce the amount of head vibrations ver much.
As a first advice , dont touch your chest with your chin. - Charlie
January 22nd, 2007Much of the reason this model causes resonance in the eyes, teeth, etc. is because the platform creates a 3-pronged vector of vibration that travels past the hips and into the long bones of the spine.
Other platforms with a teeter-totter allow the vibration to be absorbed in the hip musculature, which is quite desirable from a human performance standpoint, but it is more important to realize that this limits what gets up the spine and to the head.
Following those deeper squatted positions that PowerPlate professes of course will dampen the vibration through the flexed ankles and knees. But now we trade that degree of comfort for less joints, the hips specifically, receiving vibration.
I am sore to say that even the nominally priced PowerPlate Home Edition is some very poor technology and is not a wise choice. - Kirk

September 16th, 2008I bought a DKN Pro yesterday and am anxious to start using it. I have Multiple Sclerosis and am in a wheelchair. I’d thought of starting by sitting in my chair with just placing my feet on the platform. After a few weeks, hopefully I’d be able to sit on the platform itself. Ultimately gaining the strength of be able to stand on the machine.
What bothers me is that in the short session (2 minutes) in the shop, my eyes felt like they’d vibrated too and didn’t feel normal until after a night’s sleep. Can it do any eye damage?
Secondly (once I’ve got my confidence back) can you recommend any exercises to do from a wheelchair?
Many thanks, great site.

September 16th, 2008I had the same problem when trying a Free Motion Itonic and the personal Power Plate and some other model that I can’t recall the name of, when I was doing some shopping around. The Power Plate one ended up giving me a better workout (subjective muscle fatigue) than any of the other ones. I think the rattling sensation was mainly a problem with bad ‘form’. I worked around it with time on the machine. Good luck with yours.
Janet…
(1) What pose gave you the eye issues ?
(2) Sitting on the machine is only a massage ( always lean forward with this one ), it will not help with muscle development. Just circulation.
(3) Lack of pressure (weight put on machine) is the one point that can hold you back. Eg.. Sitting is not enough , but you cant stand yet.
So get something like a walking frame around the product , so you can stand and hold yourself up.Note: Make sure your legs are bent , or you will only do damage to your joints if you dont.

September 18th, 2008Thanks Lloyd.
At the moment I can only do one pose - sitting in my wheelchair! (with my legs bent at the knees and my feet on the platform) I realise it is only a massage to most but for someone who hasn’t really used their legs much for a few years, believe me it is incredible. Just 2 minutes a day on the lowest setting my lower legs already feel stronger and I have sensation in the soles of my feet. Now either the weakness in my waist/hip area notices more in comparison or the machine doesn’t like the way I have to sit. (I’m pleased to say my eyes have been fine on this lower frequency.) Sitting with your feet on the machine is Vibration Therapy and will have a positive effect on your muscles. I was refering to the pose where people actually sit on the machine. Sorry for the confusion.

September 21st, 2008I’ve graduated to be able to stand on the machine for 1 minute a day - and wow, even at the lowest setting, I feel I will be able to walk again by the end of the winter.
I’d still like to use the machine sitting as well but know it was feeling like it was damaging my hips/pelvis. Are there any counter poses I could do (bearing in mind they’d either have to be sitting, or standing for a minute maximum).

that’s a fair point. I am no scientist, I am not even that intelligent, I am a musician! But yeah, it did trouble me that what I felt on the low setting, which is the 30hz one on the power-plate personal, was a vision blurring sensation that just somehow didn’t feel healthy. I feel similar sensations when I boost the bass on my bass amp at about 35hz!
I have emailed the people at Hypergravity to find a UK distributor/salesperson. These people seem the best option for what we want, a personal unit to be used at home for no more than an hour (by everyone in total) every other day. If you did offer a personal model Lloyd, you’d be the man. I have read many of your posts from a few different sites and what strikes me is your honesty and passion towards this whole WBV thing.
