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.
|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).|
