Patients on continuous intrathecal baclofen therapy may develop tolerance. Dosage increases were significant in the first year post-implantation, but stabilized afterward for spasticity management.

Area of Science:

  • Neurology
  • Neurosurgery
  • Rehabilitation Medicine

Background:

  • Continuous intrathecal baclofen therapy is increasingly used for spasticity.
  • Concerns exist regarding the development of tolerance with long-term use.

Purpose of the Study:

  • To investigate the time-course of baclofen dosage requirements in patients receiving intrathecal baclofen therapy.
  • To assess the relationship between time and dosage needs for spasticity control.

Main Methods:

  • Retrospective study of 18 spinal cord injured patients.
  • Analysis of baclofen dosage adjustments over time post-implantation.
  • Comparison between completely and incompletely injured patients.

Main Results:

Related Experiment Videos

  • A significant increase in baclofen dosage was observed during the first 12 months post-implantation.
  • Baclofen dosage requirements stabilized after the initial 12-month period.
  • No significant differences in initial dose or tolerance trends were found between patient groups.

Conclusions:

  • Intrathecal baclofen therapy requires dose escalation in the first year for spasticity management.
  • Tolerance appears to stabilize after 12 months of continuous therapy.
  • Patient injury completeness does not significantly impact initial dosing or tolerance development.
