The color scale (calibrated legend) indicates low pressure in blue and
goes to high pressure in red.
The barefoot picture (maximally pronated) shows how this right foot
is carrying most of the pressure towards the inside of the foot under metatarsals
1-3 with the highest force under metatarsal 3. The outside (mets 4-5) are
in very light shades of green and blue indicating very low force, so that
the balance (alignment) of this foot is a little like a teeter-totter.
The next picture is with the patient's traditional orthotic and you
can see an improvement in reduction of force under metatrsals 1-3 and some
improvement starting to show under met 4. The orange teardrop under the
metatarsals is the edge of the patient's orthotic and is not to be confused
with the metatarsal force.
The picture with the SDO shows not only reduction in force, but spreads
the force out across the ball of the foot which is what an orthotic does
in order to be more effective.
