Definition Return to top
Spasticity is stiff or rigid muscles with exaggerated, deep tendon reflexes (for example, a knee-jerk reflex). The condition can interfere with walking, movement, or speech.

Spasticity generally results from damage to the part of the brain that controls voluntary movement. It may also occur when you have damage to the nerves traveling from brain down to spinal cord.
Symptoms of spasticity include:
Spasticity may also interfere with speech. Severe, long-term spasticity may lead to contracture of muscles, causing joints to be bent at a fixed position.

Your doctor will perform a physical exam and ask questions about your symptoms, including:
Your doctor may refer you to a physical therapist. Physical therapy consists of variety of exercises, including muscle stretching and strengthening exercises. Physical therapy exercises can be taught to parents who may then help their child perform them at home.
Medicines for spasticity include baclofen, tizanidine, cyclobenzaprine, and benzodiazepines. In rare cases, a pump may be inserted into the spinal fluid to directly deliver medicine to the nervous system.
Botox injections may help relieve spasticity symptoms in some patients.
Sometimes, a person may need surgery to release the tendon or to cut the the nerve-muscle pathway.
