Our muscles need to maintain constant tension to prevent our bodies from collapsing in a heap. The level of tension varies from day to day and hour to hour in everybody.
However, for some people with neurological conditions, the level of muscle tension can uncontrollably increase to a severe level. This is called hypertonicity or spasticity.
Spasticity is one of the most common symptoms in MS; some degree occurs in an estimated 80% of people with MS. It affects the legs and torso more frequently than the arms, and can also cause the calf muscles to rhythmically contract and relax (called clonus).
This increase in muscle tension can significantly interfere with daily activities.
This booklet has been written to help lessen the impact of spasticity on your life. It contains information on the best ways to manage spasticity, including some strengthening exercises especially designed for people with MS.
