Need help for Gait analysis progam!!!

    Hi all,

    was hopping to get advice on what gait analysis program is best for private practise with video and 3D pressure patterns on a computer?

    Whats everyone using?

    Thanks

    Tin

    I use an ipad with Ubersense app. The app is free and you can slow it right down, scroll back and forward and draw lines and all the other stuff patients like to see. It also allows you to email the video to the patient.

    Sounds like an inexpensive option - any ideas about repeatability and reliability?

    For vertical loading I use a Tekscan Matscan system. Good for recording data, no worse, no better than other systems of a similar price, good for parient education, and good for baseline data recording for new paediatric patients.

    I have used Tekscan Matscan and F-scan ( in shoe sensors) and Pedi-Gait video (4 camera) for analysis. Also I recommend having a walkway or treadmill so you can view patients from side for sagittal plane changes. I have only good things to say about these systems and have not used other competing systems like Pedar etc. When I was in private practice the custom foot orthotics I prescribed per week nearly doubled over about a 4 month period after I started gait analysis testing. Performing these tests can help you distinguish yourself from the podiatrist down the street.

    There is also a down side to gait analysis. You may have to hire and train additional staff. The system won't pay for itself if you do not have enough patients use it. A few years ago insurance companies in the U.S. stopped paying for the test and patients have to pay cash. You may have to spend some time and money on marketing, advertising, etc. Furthermore, double blind outcome studies looking at outcomes with custom foot orthotics prescriptions with and without gait analysis assistance are lacking.

    I suggest taking some time to think about what goals you have for patient outcomes and how advanced gait analysis may help you achieve this. Then consider gettting a system or systems that help you achieve those goals.

    I use a Zebris System from Germany. It's a good tool to see the force applied when the patient walks and runs and I've had it set up so I can see anterior and posterior in the video from the waist down. I think you get more visual info from the anterior view and never understood why most gait systems are set up to look at posterior but that's a personal thing. I don't think it's great to get people running on it as I think it changes their gait too much but overall it's a good tool to explain things to the patient and pick things up that you might not pick up otherwise.

    Are there any reliable systems for measuring joint angles? I use video gait analysis more for patient education and giving me time to think what the problem is and how to treat it. I find I get enough information from the history, joint examinations and observing them walking. I find I get little extra information from being able to watch their gait in slow motion.

    I can't comment on pressure plates as I've had little experience with them.

    Great responses. Thank you all very much, the app sounds amazing!

    I have personally traveled to a German orthotic lab and they're efficient (as with everything) in analysis and dispensing of devices. I honestly can't remember the name but I think it wa some pressure sensors placed inside the shoe of the patient with computer softwear to see the patterns.

    F Scan seems to be popular, I couldn't find a rough price though...

    Vicon used to be the Gold Standard for measuring joint angles during ambulation, but that was a few years ago.
    Incidentally the Vicon system I saw in use at Queen Margaret Hospital in Edinburgh was something like £500,00.00 worth, so as in everything there is a trade-off.

    I think for what we do most of the time your app sounds good. You should look at the vertical loading systems too - very useful for patient education - even basic stuff like "here's how the foot works - heel strike, mid-stance and toe-off".
     
  9. Here (Australia) we use Contemplas software for high speed (100 fps) VGA analysis, Parotec for in-shoe pressure measurement, and Parocontour for CAD/CAM orthotic production. This is what we use in clinic...but note we are also the Agents downunder for Parotec and Parocontour, which are from the company Paromed in Germany.

    We like Paromed technology (attempting to remove bias!) as the Parotec in shoe pressure measurement can used diagnostically, plus can be overlayed in the orthotic modelling process, and the mill can produce poron filled apertures etc from the mill (automatic and reproducible), and the pt outcome can be tested (evidence based) at time of orthotic dispense. Plus, whilst it achieves premium outcomes and is an investment, it is both durable and priced for everyday use.

    Parotec in shoe pressure measurement from Paromed may have been what you saw in Germany.

    In Australia at the National Pod Conference in June, we have a series of case studies employing the above technology (in shoe pressure measurement used diagnostically, in orthotic modelling process, and for evidence based analysis of pt results from foot orthotic; from basis of technology implemented in suburban private podiatry practice.

    Technology is viewed as either expensive or cheap...depends on what you are referencing to...the cost to health care system of high risk feet; the financial returns in private practice from bringing new technology and changing your patient mix; or comparing to existing protocols (visual gait analysis) and cost base? Can send info/pt case studies, please pm.

    I will definitely give this app a shot!

    As for Paromed, could you PM me the details especially cost?

    And with CAD CAM - I'm a bit hesitant as 3D printing might become mainstrea?

    Andy, was the app gait specific? Sorry, I'm just not sure if I've looked up the right one

    Cheers

    I use Comtemplas, sold in the UK through Mar-Systems. Can be linked with pressure plate system. Does comparison screens (before's, afters, overlays) produces smart reports and emailable video clips. We also use it for bike ergonomics. Measures angles etc. About £2,500 which includes cameras, software, computer and wide screen. We are very pleased with it and patients are really impressed with the instant reporting, looks very smart/professional.
