The Electrodynogram (EDG) system of foot-fall measurement has been in clinical use for more than 15 years. Recently the EDG was acquired by Tekscan, which manufactures the F-Scan system of foot-pressure analysis. The new F-Scan system with EDG module retains all of the benefits of the F-Scan system while incorporating the valuable temporal and pressure data comparisons offered by the EDG. This merging of technologies has resulted in a system that is more suitable for application in the pediatric patient than either system alone.
