Preoperative and postoperative dynamic electromyography as an aid in planning tendon transfers in children with cerebral palsy
J Perry and MM Hoffer
Electromyography was used to supplement clinical evaluation in planning
tendon transfers in twenty-four children with cerebral palsy. Sixteen
flexible deformities of the hind part of the foot, four internally rotated
lower limbs, and four flexible deformities of the forearm and wrist were
studied. When deforming muscles were active exclusively in one portion of
either the gait cycle or a function of an upper extremity, appropriate
tendon transfers were performed. When continuous muscle activity was noted,
tendon lengthening was utilized. The desired function was obtained in all
twenty-four patients six months after operation.
