MND: Spasticity can be an MS problem, does it get the attention it deserves? We already posted about baclafen pumps in wheelchairhealth.net . In a nutshell there were enough successes to talk to your Doctor if you have severe spasticity.
A new study on Intrathecal Baclafen (ITB) for MSers has been published in the MS Journal by a large research team from the US, UK, and Italy . The study point out even though ITB can be effective, it is underutilized by MS doctors. Why?The study claims their focus is on medications against MS itself (interferons, etc..) and less about helping the symptoms. Also ITB demand specialists to implement and maintain it. It is also a cost issue. Usually ITB is a last resort technique. But then again it might be one some patient few options. Escalating oral baclafen has its problems.
Some MS patient have turned to cannabis for spasticity. An English study concludes that it can be useful in some MS cases 
So here you are ITB or Cannabis? Might be a clear choice for some , but a comparative study of the efficacies must be done.
