As we dig deeper into the layers of foot biomechanics, we need to discuss the very important topic of subtalar joint MPP or maximally pronated position. Typically, we have a cer...

Dear Dr Feldman, this was a great review of what is available from the lab in the midfoot. I was wondering if you could elaborate on the "Carlton Saddle" a bit more? Sounds fascinating!! Rich Blake

The previous post in this series discussed the rearfoot considerations of building a custom foot orthotic, and continuing with the theme of breaking down and simplifying the process into three part...

  The last four installments in this forum dealt with the three steps of required documentation for reimbursement for custom foot orthotics and L3000. To summarize those steps were proper cli...

     I want to stay focused on my last student image from Part 3, but turn out attention to student 4. We were talking about achieving subtalar joint neutral statically when we can i...

The previous forum post on this subject discussed the basics of creating an effective and accurate foot orthotic within the confines of busy clinic practice, with limited time and resources with wh...

We frequently add varus posting for our orthotic prescriptions but there are situations where adding valgus wedges can be useful. Conditions that may benefit from valgus prescriptions include peron...

     My last post was all about Subtalar joint neutrality. It was a goal of mine to place patients statically there if I could. I am totally aware that this position of subtalar join...

Excellent job Dr Feldman. I know biomechanical practices have to move away from the one hour biomechanical exam and casting visit for many reasons. This was and is the gold standard for biomechanic...

  This article is part one of a four part series on building an accurate and effective custom foot orthosis. It is assumed that the reader is a busy, overworked and underpaid practitioner, wh...

     In my last post (Part 1: Why use functional foot orthotic devices?), I boldly implied that using a good lab and taking a good impression of the foot, typically helps patients bo...

     One of the funnest parts of practice in biomechanics is reviewing slow motion of your patients from their smart phone. This feature can be used in your office, or by showing pat...

     Where do we begin with this topic? Even though you probably use functional foot orthotic devices for many reasons, there must be a main reason or two or three that comes to min...

Posterior Tibial Tendonitis (PTT) often correlates with a pes valgo planus foot type, leading to excessive strain on the tendon. While some might focus solely on strengthening the tendon, it's cruc...

When treating lower extremity problems, proper achilles and plantar fascial stretches are commonly prescribed. There are many versions of these stretches and I emphasize not to do negative heel str...

Dr Pearl (Ben), excellent introduction to the use of video in your practice. It is so fun to have patients bring in video of their sport, even ones I had never heard of. Sports with repetitive moti...

     The above flat feet can be very stable, but if over pronated, they are probably not. This blog post summarizes the injuries or pain syndromes that have been tied to over pronati...
