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.

RGL_ankle_exam2_internet Limitation on ankle extension may result from tight calf muscles (Gastrocnemius and Soleus)
RGL_heel_position3_internet Evaluation of the rear-foot, includes motion at the sub-talar joint, and its angular relationship to the lower leg.
RGL_1MPJ_exam_internet 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!
Calcaneal_stance_position2_internet The biomechanical evaluation includes an evaluation of foot, leg and body position while weight-bearing.
RGL_applying_plaster_internet Finally, plaster splints are applied to the feet.
RGL_neutral_position_cast1_internet 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.

Casts_on_two_feet2_internet Here the casts are dry and ready to be removed.
Orthotic_with_2-5_bar3_internet A short time later, VOILA! a finished functional foot orthotic (one of a pair).
