Spasticity is a muscle control condition in which certain muscles continuously contract. These contractions cause tight and stiff muscles, spasms, hyperactive reflexes and the inability to control these muscles. The cause of spasticity is an imbalance of signs from the central nervous system to the muscles, and it is commonly comorbid with cerebral palsy, stroke, multiple sclerosis, traumatic brain injury or spinal cord injury. Treatments include physical and occupational therapy, medications, BTA injections or surgery.
Organizations exist to support and help those dealing with spasticity in their lives.
