Baclofen is a prescription drug used to treat muscle spasms in individuals with neurological conditions.  It can be taken as tablets or intrathecally (a pump that’s implanted in the abdomen and delivers a small dose directly into the spine).  Baclofen works by reducing nerve signals to muscles, helping to decrease muscle tone and spasticity.   Dosage is important because if the dose is too big, it would severely limit any voluntary muscle contractions and also affect your alertness.  An optimal dose does however offer your rehabilitation team a window of opportunity to try and strengthen key muscles when it “relaxes” the muscles that are notoriously stiff.  Good communication is needed between your rehabilitation team and doctor to find the correct dose.    Rekand, T., 2010.
