Factors affecting GDI improvement after single event multilevel surgery in patients with cerebral palsy

Pathologic gait is common in patients with cerebral palsy (CP). Single-event multilevel surgery (SEMLS) is a combination of surgical procedures to improve pathologic gait in patients with CP. However, the effect of each procedure is difficult to predict. The gait deviation index (GDI) is useful in comparing pre- and postoperative improvement. In this study, we evaluated the degree of GDI improvement in patients with CP and analyzed factors...
