With the horizon view, barefoot, we see this patient appears to be a
heavy heel striker. The small bridge of blue is the area of the arch
making contact with the floor. We see the forces of the metatarsals
and the next grouping of the forces of the toes. Compare the height
of all the peaks. Compare the distance from front to back where the
peaks of pressure begin and end. This is the amount of time it takes
for the alignment to come under control. The shorter the distance,
and the lower the peaks, the greater efficiency over time.
With the rigid orthotic, we wee a reduction in forces in the metatarsals
with the exception of metatarsal 4. However, there is a greater
amount of time involved in getting alignment. The orthotic has not
controlled enough of the force under metatarsal 4 and is distorting the
balance of the rest of the foot.
The picture with the SDO clearly shows more improvement in ground
reactive force (GRF) and grouping of the function of the metatarsals.
See how the arch is helping absorb more pressure and redistributing the
silicone so that the ball of the foot is as balanced as it can be.
This affects the alignment of the entire musculoskeletal system.
As we turn the picture (the Tilt views) you can see which picture looks
best.
