Purpose: To evaluate the impact of lateral walking training with mirror visual feedback on gait in children with hemiparetic cerebral palsy (CP). Methods: Sixty children with hemiparesis and aged from 5 to 7 from both sexes recruited in the study according to the following inclusion criteria: grade 1+ to 2 of spasticity based on modified Ashworth scale and they were able to walk independently at level II based on Gross Motor Functional Classification System. They were randomized into two groups of equivalent number. The study group was given lateral walking training with mirror visual feedback as well as a specific physical treatment program as received by the control group. Prior to therapy and three months following treatment, children underwent gait spatiotemporal assessment using 3D-Gait Analysis. The outcome measures were swing phase, stance phase, double limb support period, gait speed and gait symmetry ratio
