Computerized static posturographic assessment after treatment of equinus deformity in children with cerebral palsy.
Assessment of treatments in children with cerebral palsy has been well developed, especially in the gait laboratory. However, the prerequisite for walking is adequate postural control. We hypothesize that a treatment of an equinus deformity should improve postural control. Balance control was assessed by static posturography on the Balance Master. Nine diplegic children, six girls and three boys, participated in the study. Assessment was conducted before and after treatment of the equinus deformity. Two static tests (Weight Bearing Squat and the modified Clinical Test for Sensory Interaction on Balance), and two dynamic balance tests (Limits of Stability and Rhythmic Weight Shift) were performed on the Balance Master. After treatment, mean weight-bearing asymmetry measured by the Weight Bearing Squat was significantly improved at 30 degrees of knee flexion. In the modified Clinical Test for Sensory Interaction on Balance, there was a significant improvement in two conditions (eyes closed on foam surface and the composite score). The Limits of Stability was very difficult to perform for almost all the children. In the Rhythmic Weight Shift, mean directional control improved significantly in three conditions (left/right weight shift at 1 s of transition, front/back weight shift at 2 s of transition and the composite score of the front/back direction). The Balance Master offers the opportunity for an objective and easy assessment of postural control in children with cerebral palsy.
