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

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?

    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?

    Yes.

    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

      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.

You throw a ball up, there is a strong correlation to the ball falling back down. All experiments are looking for correlation. Correlations don't prove a thing, they only suggest it, the more correlations you have the more strongly it is suggested until at some point a line is crossed and you work with that is most likely.

      Anecdotal evidence is also the only kind. After all, at the end of the day all you really know is that in your experience everybody has said the ball will fall and from what you've seen that is the case. Reproducable?

They focus on the wrist and hand (because that is where the discomfort is felt), even though everybody should know that a lot of the motion there is controlled by the muscles in your forearm and to a lesser extent your upper arm ( http://www.bisonstrength.com/blog/wp-content/uploads/2010/04/posterior-forearm-muscles.jpg ).

      Like with all massages, the trick is to find the muscles that are cramped and coerce them to relax. A two finger pinch or one finger 'twang' is usually best for small muscles. Just start with one finger and twang away at the muscles above and below your elbow until you find the muscles that feel like strings instead of mushy ropes. I guarantee that when you encounter one and give it a good twang, you will feel it all the way to the tips of your fingers. During the massage, you will experience increased blood flow in your lower arm and the numbness will generally go away.

      Looking at the issue from this angle, it seems fairly obvious why and when some other methods are effective and some are not.

      My chiropractor did the same thing and it helped, but rather than assume it was an unavoidable consequence of mouse-work, I looked on it as a symptom and tried to identify the root cause.

      I came to the conclusion that the problem was an "inversion" (for wont of a better word) at the base of the thumb, that is to say that while the second joint was turning inward, the other joint was turning outward, giving it a sort of S-shape. The reason this was happening was that I was using my palm and the base of my thumb to grasp the mouse, rather than holding it in my fingers as you're meant to. In order to fix this, I got a couple of foam pads (intended to stop desk drawers banging shut) and stuck them on my mouse where the base of the thumb usually rests, making it impossible to invert the joint.

      I noticed also that this habit extended to the way I held a glass of water -- I was flattening my hand around it, so that I had an arc of continuous contact from the tip of my index finger to the tip of my thumb. I corrected this every time I noticed myself doing it, by shoving one of the fingers (on my other hand) between the glass and the thumb.

      The difference in hand posture is dramatic: my old grasp involved the pad on the face of my thumb, whereas now it's the side of the thumb that connects with the glass, and the fingernail faces skyward (when I'm holding the glass vertically -- not when I'm tipping it to drink).

      The Evoluent mice address one problematic ergonomic factor, but the design introduces another rather dangerous one.

      Good: The vertical design means less rotation of the forearm, which is more natural and less stressing.

      Bad: You fingers are all resting on top of buttons, which means they can't be used to grasp the mouse. Instead, you have to pinch the mouse between the palm of the hand and the bottom half of the thumb. This introduces a lot of tension into the finger flexors, which is increased dramatically when you attempt to click buttons. I found the Evoluent caused far more pain that it resolved.

      Bad: As a result of the problematic grip, the wrist is forced to extend -- that is to say that you cannot move it with a straight wrist, or it ends up slipping out of your hand. Look at any photo on-line and you will see that the user's wrist is bent back. This means that the tendons aren't running straight, which can exacerbate most hand problems, and is something best avoided.

      Conclusion: The Evoluent is a "sticking-plaster" solution that patches up one problem, giving the user immediate relief from certain salient symptoms, but at the cost of introducing more problems in the long term.

      My situation: My problems were caused by nothing more sinister than excess tension in my arms, with various muscle groups fighting against each other rather than working together. This is the simplest type of problem, and therefore the simplest type to treat. Also, because it is the simplest, it is (I'm told) the most common. More serious underlying problems can be the result of excess muscle tension, or they can be exacerbated by excess muscle tension, so anyone suffering pain is going to benefit to some extent from eliminating it, even if they will still need treatment for other problems subsequently.

      My recommendation: I use my thumb and pinkie (AKA "little finger") to trap the mouse (NB: not "grasp" -- it's a loose hold). I hold my hand so that my wrist is straight, meaning my palm does not touch the mouse during operation. I use my arm to move the mouse, I do not twist or bend at the wrist. <-- This is standard advice on how to use a mouse, although not a lot of people actually do it. When I want to scroll, I use the cursor keys or Pg Up/Dn, rather than clicking and dragging a scroll bar or contorting my finger around a scroll wheel, and I Alt-Tab and Ctrl-Tab between windows to avoid unnecessary mouse use. <--This too is standard advice, and it is generally quicker than constantly switching between mouse and keyboard. I am right-handed, but I'm now a leftie mouser, because that way the mouse is closer to you when using a standard keyboard.

      Sometimes I even use a control pad. I have a controller with dual analogue sticks, 6 normal buttons and 4 shoulder buttons.

      The first analogue stick is the mouse pointer, the second has the scroll wheel on one axis. The control pad emulates the cursor keys. I have right and left click on the left shoulder buttons, meaning I have basic mouse control for one-handed use (left hand). The main buttons (on the right) are configured to left-click, right-click, enter, space and tab, giving me the majority of keyboard navigation controls, and the right shoulder buttons are escape (for cancel) and Alt (so that I can Alt-Tab between windows.

      Actually, tell a lie... it used to be that, but I decided that the ctrl key was more important to me than a second right-click and I switched the right-click shoulder button for ctrl, so now I can browse without impediment, alt-tabbing to my browser window then control-tabbing between pages.

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.

      I'm not sure if just recovery works for everyone.

      I recently had wrist pain that lasted for almost 2 years. For a year I used the mouse with my other hand, but I was still using the keyboard and sometimes a pen. Then for half a year I tried typing with one hand and used a wrist brace.

      When that didn't work, I finally tried to do simple wrist exercise - wrist curls, grip strengthening and stretching, usually after using the keyboard - even if it's only supposed to be used proactively. 3 months later the pain went away.

      Granted - it might be that I did need to let it rest for a while, but probably not for 1.5 years.

  32. My mother got me to try it by Anonymous Coward · · Score: 0

    My mom worked in the call center of a outdoor gear retailer that may or may not have involved equipment of the recreational variety. She was working on a computer 40 hours a week. For some reason the company started passing out DynaFlex, probably in an attempt to get the call center to push it. My mom tried it out for a few weeks, and said it really strengthened her hands and wrists, but she didn't keep at it.

    I have minor CTS, with occasional tingling in the wrists after long computer use, and when I complained about it with my mom in earshot she got me one as a "present". I used it for 10 minutes on each hand every day for two months. While I certainly felt like I had stronger wrists and hands, my CTS symptoms were no less frequent than they were before. What did help me was getting an ergonomic keyboard and mouse, with a new desk, and taking more breaks when I worked.

    In all, I'd say you should avoid them unless you specifically need to strengthen your hands and wrists. They don't have any evidence showing CTS symptoms being relieved, and they certainly weren't in my case.

    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 it really starts to burn.

    If you make a hard fist in your right hand and then rotate it clockwise, you'll fire the muscles in your forearm that the ball targets. It also works the top of your wrist, down the middle, as you try to stabilize the ball against the force of the rapidly spinning gyroscope.

  48. Wrists, arms, shoulders, upper back and neck by Anonymous Coward · · Score: 0

    I have an NSD Powerball (cheapest model I think). I had no wrist pain, but I found my wrists and the muscles in my forearm increased in strength noticably, while stiff muscles in my shoulders, neck and upper back (from stress and using keyboards and mice far too much) improved a lot.

    They work because you have to control the energy you put in it yourself, and the better you're trained in it the more energy there is to keep under control. I've handed it to others after getting it to rotate as fast as I'm used to and they generally were quite surprised at how much strenght was needed to keep it under control.

    I remember once playing with one from another brand someone else had. The ball was lighter than my NSD's and it didn't do much for me. I don't think a much heavier ball than the one I have would be good for me, I have a feeling it would probably increase the chance I overdo it and hurt myself. It seems to me that the balance between how fast the movements you make are and the force they result in needs to be right for you, so I guess the weight and size (but I don't think size varies much) of the ball needs to be right for you. But I would have to use a heavier one than I have now to be sure about this, perhaps I just wouldn't speed it up too much and be happy with it.

  52. This did not help my tendonitis by gummogabbo · · Score: 1

    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 amount of strengthening/stretching would help because ultimately my tendons needed to heal.

    Thankfully, I found a therapy that did a great job of helping my wrist/arm tendons heal and I haven't had problems with tendonitis for a couple years now. For anyone struggling with wrist/arm tendonitis, I HIGHLY suggest you do the following at least once a day until your tendonitis is gone:
    Get around 10 pounds of ice from a gas station and put it in a bucket wide enough that you can fit both of your forearms comfortably in the bucket (I used a plastic foot bath bucket). Fill the bucket with water so that the ice moves around freely and it is easy for you to completely submerge both of your forearms in the bucket. Now that you have the ice bucket ready, fully submerge both arms in the ice water for between 10 to 20 seconds. Continue to do this every 10 minutes for about an hour.

    I often did this for up to 2 hours, usually while watching tv or something. All in all it took about 6 months of doing this everyday before I was tendonitis free (though my arms felt much better after just a couple weeks), but it was well worth it, as I was getting ready to change professions.
    I found this therapy from a book I bought from this site: www.tendonitisexpert.com
    As the site explains, the above therapy addresses a vicious cycle of inflammation that prevents healthy blood flow to the tendons. By forcing blood in and out of the affected areas with ice the cycle is disrupted, your tendons slowly start to heal. Definitely give it a try, it changed my life!
