Plantar pressures and ankle kinematics following anterior tibialis tendon transfers in children with clubfoot

Materials and methods Thirty children (37 feet) were evaluated preand 2.0 ±0.6 yrs (range: 0.8 to 2.9) post-op following ATT transfer. Foot progression angle (FPA) and sagittal ankle kinematics were assessed using a VICON system. Plantar pressures were collected using the Emed ST Platform. Representative trials were chosen for each subject for gait and plantar pressures. Plantar pressures were divided into medial and lateral hindfoot, midfoot and forefoot. Variables included: contact time (CT%), contact area (CA% total), peak pressure (PP), hindfoot-forefoot angle [2], deviation of the center-of-pressure (COP) line and region of initial contact. Twenty age matched controls were used for comparison.
