Gait parameters of children with spastic diplegia: a comparison of effects of posterior and anterior walkers.

The purpose of this study was to compare the effects of posterior and anterior walkers on the gait parameters of five children with spastic diplegic cerebral palsy. Computer-based kinematic analysis was used to investigate differences in gait. Gait laboratory data indicated that use of the posterior walker (1) facilitated more upright posture in these subjects, as seen in decreased trunk and hip flexion during stance phase; (2) decreased double stance time; and (3) increased walking velocity. According to parent report, both the parents and their children preferred the posterior walker. Most parents also reported that when using the posterior walker, their children walked more normally with increased stability and interacted more easily with other children.
