Intrathecal baclofen therapy is when a pump placed in the child’s abdomen delivers a muscle relaxant called baclofen into the fluid surrounding the spinal cord. The amount of baclofen released can be adjusted if spasticity is worse at certain times of the day. Since the pump reduces muscle spasticity throughout the body, it is most appropriate for children with chronic, severe stiffness or uncontrolled muscle movement throughout the body. The Spasticity and Intrathecal Baclofen Pump Clinic at Arkansas Children’s takes a team approach to evaluating spasticity treatments. Our neurologists, advanced practice nurses, physical therapists and others help diagnosis and provide ongoing management of children using baclofen pump therapy.
