Computerized plantar pressure mapping helps to identify areas of high peak
pressure, and how the body mass moves over the foot. High pressure shows up
in red. As pressure diminishes, the colors cool to blue. The line running
from the heel to the toes shows the progression of the Center of Pressure
over the foot.
The timing of events during the gait cycle can be studied from computer
generated graphs.
 
The biomechanical examination is a critical part of the evaluation for
functional foot orthotics. Assessment includes muscle strength, range-of-motion
at important joints, and the angular relationships of segments of the foot and
leg. This information is considered when prescribing an orthotic
appropriate to the patient's needs.

The doctor evaluates hip range-of-motion with the knee
flexed. |
|
 |
Range of hip flexion with the knee extended is evaluated.
Tight hamstring muscles will result in diminished motion. |
|
 |
Limitation on ankle extension may result from tight calf
muscles (Gastrocnemius and Soleus) |
|
 |
Evaluation of the rear-foot, includes motion at the sub-talar
joint, and its angular relationship to the lower leg. |
|
 |
Motion at the great-toe joint (first
metatarsal-phalangeal joint) is critical for the forward progression
of the body during gait. A lack of motion here can cause an early
arthritis in the joint, and even lower back pain! |
|
 |
The biomechanical evaluation includes an evaluation of foot,
leg and body position while weight-bearing. |
|
 |
Finally, plaster splints are applied to the feet. |
|
 |
The feet are held in neutral position. Improper
casting technique and biomechanical assessment are leading causes of
treatment failure and/or the inability to tolerate orthotics
devices.
Proper functional orthotics can not be made from foam
impressions, foot-prints, etc. |
|
 |
Here the casts are dry and ready to be removed. |
|
 |
A short time later, VOILA! a finished functional foot
orthotic (one of a pair). |
