Multiple Sclerosis Clinical Services at the UCLH National Hospital for Neurology and Neurosurgery, Queen Square. The Spasticity Service and Intrathecal Baclofen Clinic The service offers a comprehensive, responsive multidisciplinary service to patients with spasticity associated with multiple sclerosis (MS). Therapies provided include multidisciplinary assessments, video clinics, specialist physiotherapy, nurse-led telephone clinics, botulinum toxin and intrathecal therapies. Inpatient procedures including trials of both intrathecal phenol and baclofen take place on the Neurorehabilitation Unit, as do implantation of intrathecal baclofen pumps. Occasionally an individuals' spasticity cannot be managed sufficiently despite optimising posture, bladder, bowel and skin regimes, stretching and exercise regimes and oral medication. In this situation an inpatient admission for further assessment is recommended; during this admission trials of intrathecal medication may be performed. Baclofen is a common drug given to treat spasticity. Unfortunately when baclofen is taken in tablet form it may cause side effects. In order to get the baclofen directly to the spinal cord it can be delivered by an implantable pump. The pump is placed in the abdomen and a catheter delivers the baclofen into the intrathecal space (the space around the spinal cord within the spine). This method uses much smaller amounts of baclofen to treat the spasticity, thus reducing any side effects. If the trials show a beneficial response and the team and patient are in agreement, then a baclofen pump will be fitted. It is important to remember that intrathecal baclofen treatment requires commitment from individuals during the trial and implant phase but also for its ongoing maintenance of regular refills and replacements. Once a baclofen pump has been fitted, the patient will be regularly followed up in the monthly Intrathecal Baclofen Refill Clinic.
