You might think your shoe is doing more to control motion of your foot than it is actually doing.

You might think your shoe is doing more to control motion of your foot than it is actually doing.

"The measurement of rearfoot kinematics by placing reflective markers on the shoe heel assumes its motion is identical to the foot’s motion."
The results of this study revealed that "calcaneal frontal plane ROM was significantly greater than neutral and support shoe heel ROM. Calcaneus ROM was also significantly greater than shoe heel ROM in the transverse and sagittal planes. No change in tibial transverse plane ROM was observed."

It is easy to underestimate the calcaneal ROM across all planes of motion. Motion is going to occur somewhere, hopefully you can help your client control the excessive ROMs that are occurring and causing their symptoms. But just do not think that a shoe is going to markedly help, it might, but let your interventions and your client's feedback on pain lead you.

The Pitfalls of Motion Control Features.

Welcome to Monday, folks. Today Dr Ivo discusses why not all shoes are created equal and why you need to understand and educate your peeps about shoes!

Internal tibial torsion is when the foot is rotated internally with respect to the tibia. When the foot is straight (like when you are walking, because the brain will not let you walk too internally rotated because you will trip and fall), the knee will rotated OUTSIDE the saggital plane (knee points out). Putting a medially posted shoe on that foot rotates the foot EVEN FURTHER laterally. Since the knee is a hinge joint, this can spell disaster for the meniscus.
