if there is an area of scarring between the brain and the point where the nerve from the limb joins the spinal cord. The reflex action takes place but the message to or from the brain is interrupted. Thus no message to relax the muscle again is received or is delayed and the muscle remains contracted and stiff.
The degree of spasticity and spasms can vary from person to person, day to day, hour to hour and can impact on many activities. Nevertheless, spasticity can be successfully managed.
In an MS Society survey, 64% of people with MS reported muscle stiffness and 51% muscle spasms. Further, 17% stated that muscle stiffness caused them the most difficulty and distress on a daily basis and 14% reported similarly on muscle spasms

Consequences of spasticity

Spasticity can affect physical activities such as walking, transferring, picking up objects, washing, dressing and sexual activity. It can also have an emotional impact, on for example mood, self-image and motivation.

Management of spasticity

It is important to prevent aggravating factors. Spasms, for example, can occur in response to sensory stimulation such as skin irritation, pressure sores, ingrowing toenails or visceral stimulation including incomplete bladder emptying, constipation, or infections such as urinary tract infections.
