    ...but that is NOT 'proprioception'

    and even if it was and the dynaflange did work that way (which it doesn't), that is no different to how any rearfoot post on an orthotic would affect that alleged "proprioception"

    .. and yes it brand damaging marketing nonsense.

    Agreed - proprioception is not just additional stimuli and variability in sensory input, it is awareness of body segment positioning in relation to movement. "Sensory locomotion". That being said it is such a familiar term in marketing, and most orthotics do change the sense of body and body segment position, so you are right again. Some may do it more than others though and add the additional, stimulating, component of being dynamic and elastic....but that is another story. A fun investigation that involves a look at all components of movement.

    Hi Craig;

    Have you spent a day wearing the DynaFlange orthotic or dispensed them to patients?
     
  4. Jay:

    Here is what I asked of you over a year ago:

    Are you still expecting us to take your word, words coming from an individual who has a financial interest in a product, that the DynaFlange orthosis is somehow better than other orthoses? We have waited a year, Jay, where is the independent confirmation that the DynaFlange foot orthosis is any better or does anything more than a normal foot orthosis with a piece of cushioning material placed under the rearfoot post of the orthosis?

    Like others who come on here to Podiatry Arena for the sole purpose of selling their product, you seem to be like all the others, Jay, to not have any objective data that was done by independent researchers to back up their claims that they continually make of their product.

    Jay, please prove to me and the others following along that you are different from the others. However, in the mean time, I won't hold my breath.

    Good morning Kevin:

    As far as "taking my word", I was hoping, that since you have been a player in this debate and have a mastery of the subject, that you would be a supportive colleague and try it and hit me with feedback. One of the other commenter did just that and was quite pleased with the DynaFlange. I told you that I would be happy to arrange that and you have NOT taken me up on this.

    With regard to "selling" my product and me being "different" than others of that ilk, I bring over 30 years of experience to the table and continue to engage in this conversation with little acknowledgement for my points. i.e. the discussion about elastic energy and superior products to accomplish this end.

    With regard to studies, the white paper provides temporal and spacial data with comparative analysis, phases of gait, step length, cadence and their differentials as well as balance parameters seen in "butterfly graphs". And to state this again, the examiner and I work together now, BUT did not at the time of the study. As a clinician, one cannot ALSO (but not only) dismiss the consistently positive comments of those who wear and reorder the DynaFlange. I have well over 300 folks in them and that is important--again, our patient feedback is relevant and important.

    To money, I believe in protection of intellectual property to make sure standards are maintained. The few dollars I made have not come close to the expenses to date. The fact is, any more studies I do are going to be seen as self-serving and no one else has felt the need, or is willing to fund a study. So, you may question some of the claims but if folks in this sandbox want to throw stones, you show me "3D motion analysis and inverse dynamics" to disprove the elastic energy component of DynaFlange. I will be happy to review the protocol if you wish.

    What really bothers me Kevin, are the personal attacks and the comments of those who have no experience. Please join me in asking the readership not to make disparaging comments without the same proof you ask of me. I have always been willing to share what parts I have, and what parts I don't and what is just unrealistic, yet no one here has offered to help. I really believe in this and know it helps patients. The theories, patient experience and the data tell a compelling story, even if it is not yet enough for some. Why not help, isn't helping patients what practicing medicine is all about.

    Respectfully, Jay

    Nope. What has that got to do with Langer and TOG making up stuff in their marketings about how they work?

    That does not means that they work or do not work. I am however, intrigued by them and would like to try them.

    I am also intrigued why companies make stuff up for. To me, it just damages their brand.

    If any company is going to make unsubstantiated claims or use woo, quackery and pseudo scientific nonsense in their marketing, then they should expect to be ridiculed for it.

    Hello Craig;

    Thank you for your response and I am happy to comply. Would you like them to be made by Langer or The Orthotic Group? I prefer the new top covers at TOG so if you use them, just put "practitioner pair N/C per Dr Segel and put that attention: Lena

    Respectfully, Jay
