DefinitionBy Mayo Clinic Staff
Spasticity is a form of muscle overactivity that occurs when communication between your brain and spinal cord is disrupted by a spinal cord injury, other injury or illness.
Spasticity has some benefits, such as helping tone muscles. However, spasticity may cause pain, fatigue and other problems. Also, spasticity can become a barrier to your daily activities, walking, sitting, positioning and sleep.
