title: Upper extremity tendon transfers in cerebral palsy: electromyographic and functional analysis.
abstract: This study was undertaken to evaluate tendon transfers in a group of children with spastic hemiplegia. Muscle grading, video recordings of function, and electromyographs were performed on 12 patients preoperatively. Postoperative electromyograms were obtained on 16 transferred tendons in eight patients as the children performed assigned tasks. Clinical evaluation demonstrated improvement in all patients at follow-up, which averaged 20 months. Four of the 16 muscles showed changes in their electrical activity postoperatively. Three muscles that fired continuously became phasic, and one muscle changed phase to match its recipient. Pre- and postoperative electromyography with video analysis provided a more complete understanding of the characteristics of tendon function with tendon transfers in cerebral palsy.
