Intrathecal baclofen (ITB) therapy is a treatment option for children with severe spasticity (tight, stiff muscles that make movement difficult or uncontrollable) or secondary dystonia (involuntary muscle contractions or spasms) who are not helped by Botox injections or oral medications. ITB therapy may especially benefit children with spasticity or dystonia affecting both the upper and lower body. Over time, it can markedly improve comfort and quality of life and often functioning.

Baclofen is a medication that acts in the nervous system to relax muscle movement. It can be given by mouth or feeding tube, but in ITB therapy, a pump delivers baclofen directly into the cerebrospinal fluid (CSF) in the spine (intrathecally) in constant, small amounts. This ensures that enough of the drug gets to the nerves in the spinal cord and avoids some of the potential side effects of oral or enteral baclofen.

The baclofen pump is surgically implanted in the abdomen, just under the skin, and attached to a catheter whose other end is inserted into the spinal canal in the lower back area, in the space containing the spinal fluid. Once the pump is implanted, medication dosing can be adjusted with a remote programming device by a specially trained medical provider. The pump is refilled every two to six months in an outpatient clinic, also by a specially trained provider. The pump battery must be replaced every seven years, which requires surgery.
