The goal of this pilot study to determine whether there is a significant therapeutic
advantage to place the ITB catheter within the cervical, thoracic or lumbar region of the
spine. It is also a goal of this pilot study to determine whether the origin of spasticity
influences the effect of Lioresal Intrathecal (baclofen injection) on ITB catheters located
in the cervical, thoracic or lumbar regions of the spine. The investigators propose to study
the impact of catheter location on the reduction in spasticity within a group of patients who
are scheduled for ITB trial.
