MS patients may develop weakness. But equally problematic is a type of stiffness that can develop, with or without weakness, called spasticity. Spasticity can be mild or can be so severe as to interfere with mobility or cause painful spasms.

Spasticty management usually involves stretching to maitain range of motion. Medications can also be helpful. The ones used most often include Baclofen, Zanafelx, Valium, and Klonopin. All of these can, unfortunately cause some sedation and sometimes even a mild degree of weakness. More on spasticity from the NMSS sourcebook

In some case, where the spesticity is particularly severe, more invasive procedures such as Botox Injections motor point blocks ( Chemodenervation), or Intrathecal Baclofen may be required.
