If we took an "average" shamop who wanted one or two pair of customs per day produced...

Thanks for the reading Simon. Clearly as you and Phil said there will be a rise but nothing that will have a major effect on device stiffness. The china leather article talked about 6 degee which then become stabil after a short time. Nothing to consider.

So whilst the curves typically represent the effects of the 3 rockers seen in the saggital plane on body acceleration so does a bunch of other things. I think what is much more interesting and better use of time is to look at the so...

To the less stable climate of Sweden there is a call for two different stiffness of orthotics for warm and cold activities ? Yes...

Cheers Dave I just got one of these to evaluate. As a stand alone camera they capture very nice images upto 120 fps, The 1200 is low res and needs a lot of light however it works and as means to examine behavour of foot...

Bruce, Quote: Originally Posted by Bruce Williams Not sure why it would be frustrating to intuit. We all do it everyday as we gain more experience in situations. We see patterns and intuit the cause adn effects from those patterns. Yes, I agree. I use my 15 years experience to intuit everyday and it serves me well most of the time. However, I am trying to use a bit more evidence to back up my interventions. I think it would be great to...

This may be of interest Ian

A soft Heel lift sometimes works too to dampen or keep the heel on the ground for a longer period of time. Bruce, I'm curious as to how a heel lift can both cause an earlier heel off ("stop the delayed unweighting of the...

Hi simon thanks for taking the time to respond. A few things: 1.suffered dorsal trauma which severed the FHL tendon- did you mean the EHL as the extensors are the Ant group muscles? 2. What is a cluffy wedge - i have already provided him with an orthotic to increase the supination moment around the stj. 3. Theoretically his biggest risk is from reduced 1st MTP dorsiflexion ROM - its too late as this gentleman actually already has an underlying...
