Abstract
The benefits of using computerized gait analysis to plan and evaluate operations were assessed by studying the data from 20 children with spastic diplegia and examining the changes in estimated external work of walking, stride length, walking velocity and joint rotations pre- and postoperatively. Of the 20 patients, 13 improved, 6 were unchanged and 1 was worse. None of the patients walked in a crouch postoperatively. By clinical evaluation, 19 of the 20 patients were better. Thus, objective gait analysis imposed much more stringent criteria for improvement. Computerized gait analysis enabled a more objective evaluation and documentation of outcome.
