Video CES: Can a Gyroscope Ball Really Cure Wrist Pain? (Video) 144

Timothy ran into these NSD people at CES. If we were giving out a "best huckster" award, NSD booth dude Doug Lo would surely be a finalist for it. He's one heck of a talker. The exercise balls he's pushing? A number of companies have been making and selling similar products for many years. They seem to have some medical benefit as physical therapy aids for people with wrist or carpal tunnel problems, and may also be useful exercise devices for people who want to strengthen their hands and fingers. Have you used a gyroscope exercise ball? If so, did it help cure a wrist problem or help strengthen your hands and fingers? And which of these brands (if any) did you try?


Timothy Lord: You know that CES is a good place to come to find out about things like new computers, new monitors, home theater equipment, but what you might not have known is it is also a great place to find out about all the latest advances in hand-held gyroscope balls. I can’t vouch for any of the medical claims made by this next company, but I can tell you holding one in your hand is a really weird sensation.

Doug Lo:
Hi. My name is Doug Lo. I am here at the Consumer Electronics Show. What we are introducing today is called the NSD Spinner. Basically, what it does is help you get rid of your carpal tunnel, and also tennis elbow. If you give it a minute, it will give you a very strong arm. What it does basically is, like I told you earlier, it is for the carpal tunnel, the tennis elbow. And if you give it a minute, it helps circulate your blood and also it helps your wrist. It has been around in Asia for the last 10 years. We have shipped over 10 million pieces worldwide. You can buy it at, and

Timothy Lord: Doug, could you tell us how does this work? Could you show us from the start how do you start it?

Doug Lo: You just start it, and there is no battery. It has got a gyroscope in it. And it is not by battery. You just start it, and just keeping going. And we have a lifetime warranty on parts.

Timothy Lord: How do you get it started though? How do you get the internal part going?

Doug Lo: You start it by – you wind it up, and then you just let it go, just keep going, here you go.

Timothy Lord: So do you now have incredible wrists and tendons?

Doug Lo: It actually works. It has been – we have people that just keep coming and just telling all the family members, it is a great product, and we have a great review on it and it is great for the wrist. It is all about good health and a good you.

Timothy Lord: Could you show me one more thing, the color changing, how does that work?

Doug Lo: Basically we have different models. We have some with different lighting, we have some with – we do it with stainless steel. We start retail from $25 all the way up to $100 retail.

Timothy Lord: But the LED lights in this, they change color, what is that based on?

Doug Lo: It’s just on different styles it has different lighting. Okay?

Timothy Lord: Okay.

Doug Lo: We make it fun.

Timothy Lord: Good. All right. Thanks, Doug. Thanks, appreciate it. Thanks a lot.

    CES: Can a Gyroscope Ball Really Cure Wrist Pain?

    First off, let me say that I have no formal training or any sort of degree in anything even remotely related to this. I'm not medically qualified to give you professional advice on this sort of stuff. But from using using these things, I would wager that very few kinds pain will actually be cured from this. I don't know how carpal tunnel syndrome responds to this but I thought that was a condition of the nerves and I fail to see how this could help that (I'm totally sold on muscles though and, through that, maybe extremity blood flow). I would be wary of someone selling this to me heralding it as a panacea for all things past your elbow.

    Have you used a gyroscope exercise ball?


    If so, did it help cure a wrist problem or help strengthen your hands and fingers? And which of these brands (if any) did you try?

    I had no wrist problems to begin with but a roommate at the time called them "climber balls" and said climbers use them. So, being a software developer with terrible posture by trade and enjoying video games, bass guitar playing, piano playing, more programming, book writing, etc on the side, I felt it was in my interest to try as best as possible to preserve my wrists. So I asked for one for Christmas and received the orange PowerBall pictured here with digital back []. I used it for a while and tried to do 10 minutes a day with it, alternating hands as the digital readout would let me see how fast I could get it (I think I got it up regularly to 9,000 RPM and 13,000 RPM once while incredibly intoxicated). Basically I'd burn up right off the bat with each arm and then try to get into a sustaining groove. Definitely more exerting than it looks. I would also alternate between grips. The two most comfortable ones seemed to be palming it from the back and wrapping my thumb and index finger around the grip while supporting with the other fingers. And I noticed a serious burn (a good, like exercise burn) at first in my hand and forearm but then only in my forearm. From my experience, I suspect that once your hand's grip hits a certain point it's good to go whereas the muscles pumping energy into the gyroscope are actually located in the wrist/forearm. So I believe it was working. I was, however, also doing exercises like wrist curls, inverse wrist curls, wrist extensions with a 45 lb. bar at the gym from time to time. And I was also doing other exercises that probably inadvertently helped strengthen these same areas.

    So anyway, one day my friend stayed over and brought his dog. He slept on the couch, his dog whimpered in his kennel so he took him out and fell asleep with him. Dog got a hold of the PowerBall and that was that. Recently these NSDs went on sale for $25 for Black Friday [] (as shown here []) and so I purchased two with the intent of having one at my desk in cubeland and one at home. While I'm happily using one, I left the other packaged and might gift it up because no matter how nice these balls are, they do make a good deal of noise (and the ones with revolution powered LEDs look dance-rave in the dark). The digital options on the NSDs aren't as nice or intuitive as the PowerBall LCD functions but I haven't given that a lot of time so that could just be RTFA ignorance on my part. I just use them as a straight up exercise device now with no intent of breaking records on youtube [] so I've stopped fussing with the electronics part of them. These NSDs are so far seemingly higher construction than the PowerBalls and are much easier to start but also seem more expensive. I suppose I would have to use this for a year before I start reporting on wear and tear. Watch for a sale on an NSD, when you

              That's not an anecdote. Asking someone for their level of pain on a scale of 1 to 10 is, but taking the delta between before and after treatment isn't. The delta indicates if treatment for reducing pain is working, it's working. Doesn't matter if it is a purely psychological effect or if there is some physiological basis, because pain is a combination of both.

      Carpal Tunnel Syndrome is down to inflammation of the tendons ; the carpal tunnel is the sleeve bearing that the finger tendons pass through in your wrist. The other things that passes through there is the median nerve.

      If you get tendonitis of these tendons, the inflammation can compress the median nerve, which is what causes carpal tunnel syndrome. It makes some sort of sense that strengthening this overall group of muscles can improve matters - if you predominantly use one or two fingers for your grip, spreading the load will lead to less strain on these tendons and less inflammation.

      The muscles involved in grip strength are predominantly in your forearm, and connect to these tendons. Muscles in the fingers and hand are mostly limited to fine posture - like the ability to flex the finger at the most proximal joint while the other joints remain extended (like an L shape), and the ability to splay your fingers.

      Through bad posture or excessive exercise (like a two week rowing course) I sometimes inflame the tendons on my little fingers and get a kind of bi-state "clunk" when the swollen part passes through the sheathe, and that finger will only hold postures either side of the lump - straight, or claw. And I sometimes get a generalized soreness of my fingers if I drive a lot (I tend to lean on the wheel badly). I have a Powerball of the type you describe, but not the discipline to use it regularly.

      My main problem is that if you drop one, the metal axis of the 'scope nicks the inner plastic bearing it runs on, making the thing useless (it goes *tick tick tick* and you can't speed it up as much). I thought about buying the all-metal version but as I said, I don't use it enough to justify it.

        Your description of carpal tunnel is correct, but slightly incomplete. Tendonitis is not necessary, certain kinds of overuse (like typing and mouse use) combined with never using full range of motion and no stretching can cause shortening of the muscles and tendons such that the "fatter" part of the tendon gets "pulled" into the carpal tunnel and compresses the nerves. Fortunately, that flavor of CTS, with which I am intimately familiar, is very easy to relieve ;-)

        The other approach is to strengthen/heal the affected nerves - e.g. with methylcobalamin and a bit of some other B vitamins (but not too much B6 as it can cause nerve problems too!).

        As far as I know bodybuilders and athletes do grow larger wrists and tendons over time, as such some of these problems might just be an imbalance in growth - tendons growing faster than the other parts can adapt.

      Not only popular with climbers but with handgun target shooters as well. I seriously doubt that it would 'cure' RSI but I could believe that regular use would help prevent it. Of course - correct posture/technique and frequent rests will do that as well.

      Anecdotally - I have a powerball and use it reasonably frequently - it does a great job of strengthening grip and forearms.
    • The key to this is very simple. Carpal tunnel problems do not have to do with being too weak, instead, too strong They're caused by the tendons slowly getting bigger through use, and then rubbing. The rubbing then causes the tunnel of sinews they travel through to inflame, further constricting them and compounding the problem.

      Strengthening the tendons further will not help, it will hinder the problem.

      I had carpal bad for awhile and tried all kinds of stuff. What finally worked was my noticing part of the chiropractor's treatment, which I was able to replicate myself whenever I felt the need. I told him what I was doing and he gave my 'treatment' his endorsement.

      The chiropractor had me stand straight up, with my arms down at my side. Then he'd pull down hard on my thumb until it 'popped', (as best as I can describe it). So I tried this myself by gripping my right thumb with my left hand and pulling horizontally across my chest to do the same thing.

      It seems that computer mouse-work builds up a kind of stress and this releases it, and whenever I feel the need I do this, and I've been good ever since. YMMV.

    The movement required to keep the motion going is rhythmic and needs to be controlled. You are constantly using tons of tiny stabilizing movements.

    Now the problem is when you have wrist problems it's not always easy to get a fluid motion going, or you're too used to extreme flexions which is what constricts nerve passages in the wrist in the first place. You can however use your shoulder to hold the rotation, or even your elbow if your isolations are good. Once the thing is spinning you can then experiment with wrist movement that doesn't hinder the spinning. Visualization is a good technique to use with this as well. Liken it to a game of Operation, except that you are trying to keep an open channel in your wrist. Pretty much anytime your skin get's wrinkled that's touching the side, and the gyro will pull or push you hard.

    What's frightening is the amount of misinformation of how to use your wrists is out there. I was talking to some woman off on physio for rsi and she proceeded to show me how she knew the 'correct' way to type as she showed me a broken wrist. This is what OT are teaching?? Wrist rests? Yes, let's just discourage proper posture and restrict with pressure.

What solved my problem was to simply always take my hands off the mice when not in use (I dual wield) What I was doing was keeping my hand on my mouse at all times, and resting my wrist on my desk, when reading an article or coding I would have my hand there the whole time, ev

  • I used to live in Taiwan back in the 90s and discovered these balls at the local night market. They were marketed as kids toys back then. But I discovered they rapidly increased the strength in my wrists and fingers and decreased my carpal tunnel symptoms substantially. I bought half a dozen and keep a couple around my house and still keep the others packed up in case one breaks/dies. I had no idea these balls were still around, let alone being used for curing symptoms which I had independently discovered a

    Had one of these at my desk during several jobs in the 90's. I think the main benefit was in having coworkers ask me what the hell they were and them demonstrating them, but I've always had one, enjoyed using them, and never had significant wrist problems. Ringing endorsement? No, but worth $20, sure.
  • was to start using the mouse with my left hand, and I got a stylus pen for my right. It was very slow at first, but the pain has been gone for over 10 years & now I'm fluent in mice. I don't use the stylus much anymore. Pat
  • I've never suffered from RSI. I also have a pair of the large size Chinese therapy balls (chrome plated iron balls, 1 kG each).

    One of the things that OTs (Occupational a physical therapist, but focused exclusively on hands and sometimes feet) will advise to defend against (not cure) carpal tunnel is to strengthen your grip, essentially. What they are really looking for is strengthening of the muscles and tendons that relate to hand motions using more natural (read: non-impactful, unlike typing) activities. I've been using a keyboard for over 30 years (young when I learned how to code), and have started developing carpal tunnel syndrome on several occasions. I'm currently not suffering from CT, nor have I for several years now.

    Short Answer:
    I've used one of these, and it works for strengthening your muscles...REALLY works. It's actually really wild, and you'd never believe how much of a workout it is until you try it.

    But here's the catch: when you already have CT symptoms, more exercise is not what you need. You first need to recover a bit. It's like having a hurt ankle because you twisted it, due to weak stabilizing muscles...the exercise that will strengthen your muscles will also aggravate the injury. So you have to heal first, and then prevent it from happening again. If your tendons are already pissed off at you, subjecting them to extra exercise (usually on top of everything that has caused this problem to begin with) is not the solution.

  • This thing is at least forty years old...I had one in the Seventies, under the name Dynabee. You started it spinning by sweeping the exposed side of the ball across a tabletop, and then kept it moving in a conical motion. When you had the motion right, you could feel your hand coupling angular momentum into it, and hear a rising whine as it gathered speed.

    Nice classroom demonstration of the dynamics of precession, but it made my wrist hurt like hell.

      I also used a Dynabee in the Early 80's. Worked out a routine for 15 min/wrist, 3 times a week. I believe it significantly Improved my wrist strength. Also got very good at getting it spinning. First time through it is a bear to get started.

  • The plural of "anecdote" is _still_ not "data".

    • Data isn't everything.

      It's realy simple: using these balls propperly, meaning realy getting them up to speed, requires a lot of force to keep them leveled. Force is being applied by muscles. Just like lifting weights; the more you do, the stronger you get.

      After a couple of weeks, my wrist realy grew in diameter. After I stopped, it shrank a little.

      The difference in wrist diameter was the difference between my watch fitting loose and tightly around my wrists.

      Many females who do work by hand, who develop stro

      • Gyroscopes are keeping themselves leveled, oops. What I meant was keeping it up to speed while leveled.

  • I know, because I did. If you try to make it go really fast, it will place a LOT of strain on your wrist. We had the one that lit up, pretty cool toy.

  • Used it after getting hit by a car and having my wrist pinned together. Helped me regain a lot of mobility, flexibility, and was essentially my own therapy for my wrist after the cast came off and pins came out.

    Warning, you can injure yourself with these things. They produce a damn good bit of torque when in motion, enough to strain every tendon in your wrist if you aren't careful/expecting the force. Made the mistake of handing off one of these to my friends at about 12KRPM, and he strained the hell out of

  • I have (or had) one, and liked it, but I can't find it. I got tired of being stared at on the Washington DC subway with a large round thing in my hands making a loud whirring grinding noise. It's in a closet somewhere.

    Did it actually help? I don't honestly know. It felt good.

    No, they won't fix carpal tunnel problems.
    And asking it is helps 'wrist pain' is pretty meaningless since there are so many way to get wrist pain.

    Also, acupuncture cures nothing, and homeopathy still doesn't work.

  • I bought a Dyna-Flex PowerBall years ago, maybe '05? I have been working with computers for about 30 years, but don't have any sort of problem with my wrists, so I can't comment about using them for rehabilitation. I will say that they are good for building forearm and wrist strength, you just have to be consistent about using them and you have to be able to fight through the pain. It's kind of like tapping your foot while keeping your heel on the ground. It's easy at first, but after a short period of time

  • Relieves carpal tunnel? I think it would give me carpal tunnel. Oh ya, and sex sells. Sheesh!
  • I had a really bad case of chronic tendonitis (not carpal tunnel syndrome) for about 3 years without any relief. I had inflamed tendon pain throughout both my wrists and arms all the time and I was getting ready to quit my job because of it (I am a programmer).

    This device does a really good job of building arm strength but did not help my tendonitis all that much. I think something like this may have been helpful at preventing my tendonitis, but by the time I started using it my arms were so bad that no amo

  • Due to a rather strange side-effect -- the low-frequency rumbling from the powerball made my gf feel ill when she heard it......

    You can keep your jokes and snarky comments to yourself, thank you.

  • I have a NSD powerball (250Hz) and a Prohands [] Pro medium finger exerciser (tension of 7lb per finger). I use the powerball when I feel my wrists are getting sore (after all day behind the computer or playing the guitar) and the finger exerciser when I'm thinking at work (I'm a programmer so I do a lot of that :) ).
  • I get regular pains from typing at work and sometimes the situation flares up for me when I'm typing more regularly. My symptoms are weak grip, dull wrist pain and when it gets worse, tingly fingers. Sometimes the problem was enough to cause worry. Using a Powerball (the plastic versions) has really helped. So much, I'd say that it definitely cures it for me. I only have to use it a few consecutive days for about 5 minutes, doing about 5-9,000 on the little counter (just enough to warm the wrist muscles up
  • I broke my wrist in a motorcycle accident. After the cast was taken off I started working out with a titanium Powerball. I made 100% recovery in six months, and while it's impossible to say how much the exercise helped, I'm sure it did.

  • 10 years ago I started getting stiffness and numbness from my right wrist up to the shoulder. I switched to an ergo keyboard which helped a bit, but the DynaFlex Powerball helped a lot. Since then I've gone through 3 powerballs. A couple of years ago my knuckles started stiffening and freezing up on me. To help with that I've been taking Fish Oil, which I didn't think was working until I stopped it for a week, and have been using this great ergo mouse. []
  • I have one of these from DynaFlex that I got ages ago. I'd like to use it at work, but the damn thing is so loud when it's running. Anyone have any recommendations on ones that are quiet when running?
