The Foot as a 3 Point Pivot Workshops
Experience a fresh and practical approach to foot posture, biomechanics and orthotic selection.
The latest research has proven that changes in the Supra Navicular Angle (SNA) before and during weight bearing are a more accurate and reliable method of assessing foot function than other techniques including Subtalar-Neutral. Furthermore, it is imperative to access the mobility of the 1st MPT joint, as this is a critical factor related to heel lift and achieving functional propulsion.
During the workshop we will acknowledge why and how the forefoot plays an integral role in propulsive biomechanics by examining these often neglected questions.
- Why does the pronated foot prevent 1st MPT extension?
- How does the foot recover from pronation?
- How does extension of the 1st MPT joint occur?
- What compensation may arise from diminished 1st MPT joint function?
- Which orthotic features are required from each foot type?
Changes in the Supra Navicular Angle (SNA)
As the foot loads there are two inter-related movements occurring - Navicular drop and 1st Metatarsal elevation. The change in the SNA before and during weight-bearing defines the patient's foot type and measures loading response.
Testing the ability of the 1st MPT joint to resist loading
As the heel inverts the leg should externally rotate. A low Hubsher score often indicates that the use of an orthotic will help increase MPT joint mobility.
Assessing hip alignment and leg rotation
Indicating loss of stability, uncontrolled hip rotation and generation of larger pronation forces.
