Description
Spasticity occurs when part of the nervous system that controls muscle activity becomes damaged. The damage can arise from injury or a medical event such as a stroke, multiple sclerosis, cerebral palsy, traumatic brain injury, spinal cord injury, brain tumor or brain damage, which may be caused by oxygen deficiency, encephalitis or meningitis. Overall, spasticity affects about 500,000 people in the United States and more than 12 million people throughout the world.
