NCT00356343

Brief Summary

The purpose of this study is to determine if using high-intensity, short-duration, intermittent neuromuscular electrical stimulation (NMES) is better than volitional exercise in increasing quadriceps femoris and triceps surae force-generating potential and gross motor function in children with cerebral palsy.
