Effects of Ankle-Foot Orthoses on the Gait of Children

Gait analysis was performed on five nmormal children waliking barefoot with bilateral double-upright ankle-foot orthoses (AFOs) and with plastic AFOs. When orthoses were worn. wailking speed and cadence were reduced and quadriceps EMG timing was prolonged. Changes in lower extrmity motions and torques were observed. The metal-and-leather AFOs impaired normal walking more than the plastic orthoses. This study provides baseline information for evaluation of new orthotic designs and materials for children. In clinical practice, this information may be useful in selection of orthyothic materials for some patients.
