An intrathecal baclofen pump delivers baclofen directly into the spinal fluid, calming overactive nerve signals that keep muscles tight. Because it bypasses the bloodstream, the dose is a fraction of oral tablets, with stronger relief and far less drowsiness.A programmable pump sits under the abdominal skin; a thin catheter carries the drug to the spinal canal. Used for severe spasticity from MS, spinal cord injury, cerebral palsy, and brain injury when tablets fail or cause side effects. A test dose is given first.
According to Dr. Gurneet Singh Sawhney,a neurosurgeon in Mumbai, “Patients are often surprised that the pump works on far less medication than the tablets they’ve struggled with, and that’s exactly why the side effects fall away.”
Is spasticity still limiting movement or care despite maximum oral medication?
How Does an Intrathecal Baclofen Pump Work?
Relief builds over days to weeks as the dose is tuned, not within hours.
Pump therapy sits within wider spasticity treatment options, which begin with oral medication.
Who Is a Candidate for a Baclofen Pump?
Not every stiff limb needs a pump. Mild spasticity usually settles with medication and therapy alone.
A closer look at the decision is covered in when a baclofen pump is needed.
What Are the Risks and Follow-Up Needs of a Baclofen Pump?
Follow-up determines how safe the pump is, and it’s part of care planned before implantation, not after starting, with understanding when a baclofen pump is used for spasticity instead of oral medication.
Frequently Asked Questions
How long does a baclofen pump battery last?
Typically five to seven years before the pump needs replacing. The device is monitored at follow-up visits so the battery level is never a surprise; replacement is a planned procedure, not an emergency.
Can a baclofen pump be removed?
Yes. If spasticity improves or the pump is no longer needed, it can be removed but the baclofen dose must be tapered gradually under medical supervision to avoid withdrawal.
Does a baclofen pump cure spasticity?
No. It controls symptoms effectively but doesn’t treat the underlying neurological condition. Patients with MS, spinal cord injury, or cerebral palsy still have the condition the pump simply manages the muscle tightness it causes.
How often does a baclofen pump need refilling?
Usually every one to six months, depending on the prescribed dose and drug concentration. Refills are done in a clinic a needle is used to access the pump’s reservoir through the skin.
