Pediatric tone management.

Tone management is one of the primary roles of a pediatric physiatrist. Hypertonicity frequently inhibits normal movement patterns in children with central nervous system lesions but at times can reinforce muscle group firing and be useful for a child's function. Treatment approaches should be individualized based on functional goals, degree of impairment, interference with care, and type and location of hypertonicity. Treatment plans should be created in collaboration with all individuals caring for the child. There are many causes of hypertonicity as well as many nonsurgical and surgical treatments. Historical and current evidence-based treatments are reviewed.
