  • Title: Gait changes in children with spastic diplegia after selective dorsal rhizotomy.
    Author: Thomas SS, Aiona MD, Pierce R, Piatt JH.
    Journal: J Pediatr Orthop; 1996; 16(6):747-52. PubMed ID: 8906646.
    Abstract:
    Twenty-six ambulatory children underwent preoperative and 1-year postoperative assessments after selective dorsal rhizotomy. These included spasticity, passive range of motion, tone, three-dimensional motion analysis, and electromyography. Independent and dependent ambulators were evaluated separately. A decrease in spasticity was found in all lower extremity muscle groups. An increase in passive range of motion was found only at the hip for both independent and dependent ambulators. Gait changes included increases in velocity and stride length in the independent ambulators. An improvement in hip extension during stance was found in the dependent ambulators only; however, an increase in knee extension and dorsiflexion in stance were seen in both groups. Selective dorsal rhizotomy improves both passive and dynamic range of motion in children with spastic diplegia.
