  • Summary - Balance Systems

    Sometimes ago, I sent a request for inputs on a good dynamic balance testing
    system. Basically, most people seemed to be familiar with NeuroCom EquiTest
    and Biodex. Here are the responses I received with the original request.

    Here I'd like to express my appreciation for all of the inputs I received
    from the colleagues.

    Original request -

    We are interested in getting a balance measurement system that can not only
    measure the static balance but also the dynamic balance (with tilting). I
    am aware of Balance System by Biodex, EquiTest by NeuroCom, PROPRIOT 5000 by
    Perry Dynamics, and SportKat 4000. Are there any other balance systems out
    there, which are suitable for both static and dynamic balance measurements?
    Any comments on pros and cons of these systems? Your inputs are greatly
    appreciated. I will post a summary to the list.

    Personally I have worked with two systems for balance control studies. One
    was the Equitest System and one was a system of unique design that I and my
    coinvestigators created for threshold static balance and translation work.

    The only comment I have is that if you intend to do threshold studies the
    Equitest System is not likely the best choice (I'm not sure about the other
    systems you mentioned). This system tends to produce a vibration during
    translational and rotational motion, and to some extent when static, that is
    confounding to the subject when the command input is very small. Other than
    this the Equitest system has worked very well as a gross movement system for
    the study of motor adaptation and static balance control.

    Dear Songning,

    We got your message about "Balance measurement systems" forwarded by a
    Our footscanR systems do have a balance software.

    I have included a PP-presentation about our systems, so you can have an idea
    about the specifications. And also a PDF with product description of a
    Balance 1m (3feet) system. In the presentation we have pictures from our
    Gait software, but also the Balance software can be used on the same
    platforms. And with the 3D box, you can choose your measuring speed (from
    1Hz to 500Hz)

    If you want you can always visit us on one of our next exhibits and
    congresses we participate at in the US:
    - ACSM Annual Meeting, June 1-4, Nashville, Tennessee
    - ISB Footwear symposium, July 27-29, Cleveland, OH
    - ISB meeting, July 31 - August 3, Cleveland, OH

    We can also give a demo around these dates, in that case, please let me know
    before April 30.

    More information and publications can be found on our website
    If you have any questions, don't hesitate to contact me!

    We have the Biodex system and it is good for treatment as well as assessment
    and has a Fall Protocol as I recall. The Neurocom is more expensive but
    gives more detailed patient examination information. Others I am not
    familiar with. Good luck.

    Are you interested in clinical or research applications? As I believe all
    measure center of pressure forces the real question is what amplitudes and
    velocities you want to test and the extent to which you want to be able to
    program the equipment. I have experience with the NeuroCom Systems both the
    Equitest with the data acquisition software which allows the user some
    flexibility and the new research platform. Please feel free to give me a
    call or email me with specific questions.
