In Brief:
Although ankle foot orthoses (AFOs) are often used to improve gait parameters in individuals with myelomeningocele (MMC), it can be challenging to predict which type of orthosis will best optimize a child's gait mechanics and function. This case report illustrates the clinical application of three-dimensional motion analysis technology to quantify kinematic gait variables, and the effect of external tibial torsion on those variables, during the process of orthotic evaluation in an adolescent with MMC. A three-dimensional optical tracking (VICON) system was used to compare the sagittal plane joint kinematics, velocity, and step length associated with barefoot walking, articulated AFOs with dorsi-assist and dorsiflexion stop, and ground reaction AFOs (GRAFOs).
