After gait analysis and clinical assessment of patient’s foot, the procedure takes only a few minutes. Ideal weight-bearing flow is established and controlled by the practitioner to ensure that proper plantar contour is achieved, which will eventually be duplicated in the finished orthotic device.
Align patient’s body properly. Establish 90-degree angles at hip, knee and ankle. Observe feet to ensure proper neutral positioning.
Hold ankle in neutral position by supporting the talus to prevent pronation when impression is made. Instruct patient to apply no pressure. Place free hand on patient’s knee and press down, pushing the foot 1” to 1-1/2” into foam. Simultaneously, apply pressure to lateral aspect of foot with other hand.
Finish impression by pressing on the toes with both hands. Thus, weight-bearing flow is simulated – heel to mid-foot to toes – while foot is maintained in proper neutral position.
