Between 60% and 90% of people with multiple sclerosis (MS) will be affected by spasticity at some point. Although most people will only experience occasional symptoms, about one in five people report that spasticity and spasms frequently affected them.
Spasticity is a symptom of MS that causes your muscles to feel stiff, heavy and difficult to move. A spasm is a sudden stiffening of a muscle that may cause a limb to kick out or jerk towards your body.
Spasticity can be caused in a number of ways, through diseases of the nervous system, such as MS, or as a result of an injury to the brain or spinal cord, or it can be present from birth.
