What is spasticity?

Spasticity in a nutshell

Spasticity is a word used to describe the way your body may behave following brain or spinal cord damage.

It affects the system that controls voluntary movement, muscle tone and supports the body against gravity – called the upper motor neuron system (UMN).

How many people are affected by spasticity?

Overall, it is estimated that spasticity affects over 12 million people throughout the world. 1

A 2019 study found that 45% of stroke survivors could expect to develop spasticity three months after a stroke with 35% experiencing spasticity one year after a stroke.2

Combined information from 9 studies in people who had experienced a stroke showed that spasticity was most likely to develop within the first month, with about one quarter of survivors developing spasticity at some time after the stroke. Specifically, after a stroke, 32% of survivors had spasticity within one month, 22% within one to three months, 26% within three to six months and 24% over six months after.3

Around 86% of people with multiple sclerosis have some form of spasticity, negatively impacting their quality of life.4

In addition, 19% of patients with a new diagnosis of multiple sclerosis, and 10% of those with an ongoing history of multiple sclerosis need treatment for spasticity.5

of people with cerebral palsy have spasticity

Spasticity is found in 70% of people (aged 2 to 20 years) with cerebral palsy, many of whom are nonambulatory.

Traumatic brain injury is extremely variable with regard to injury mechanisms and patterns, and up to 85% of those affected develop spasticity.7

After spinal cord injury, 65% to 74% of patients are reported to have spasticity, and 35% to 45% of patients have spasticity that is either troublesome or problematic.8

Spasticity is more common if the spinal cord injury occurs at the cervical (in 87% of injuries) or thoracic (85% of injuries) level than if at the lumbar (57% of injuries).9
