Continuous infusion of intrathecal baclofen (ITB), via implanted pump, is a powerful tool in the management of severe spasticity in neurological disorders. The advantages of ITB therapy are that it is non-destructive, reversible, and programmable, allowing for neuromodulation. Patients reported significant subjective improvements and decreases in muscle tone after baclofen injection, but excessive doses of ITB resulted in motor weakness. Few complications and adverse effects were reported. ITB therapy appears to be a promising treatment to improve residual motor control in patients with severe spasticity.
