The short answer
A single page to print and take with you. Everything on it is drawn from the full condition page, with the same sources.
In two sentences
Spastic cerebral palsy is the type where muscles are stiff and tight. It is the most common form of cerebral palsy. 1
Spasticity means a muscle resists being stretched, and resists harder the faster you stretch it. The muscle itself is normal. The signal telling it to relax is not getting through.
The numbers, with their sources
- Share of cerebral palsy. Spastic cerebral palsy is the most common type, and NINDS describes it as accounting for the large majority of cases 1
- The three patterns. Diplegia affects the legs more than the arms, hemiplegia affects one side, quadriplegia affects all four limbs and often the trunk and face 1
- Common brain finding in diplegia. Injury to the white matter next to the ventricles, called periventricular leukomalacia, which is most common in babies born early 2
- Strongest therapy evidence for one-sided involvement. Constraint-induced movement therapy improves use of the affected arm in children with unilateral cerebral palsy 3
- Hip surveillance. Hips can move out of joint slowly and without pain, which is why X-ray surveillance on a schedule is part of standard orthopedic care 1
What to do this week
- Ask for the type, distribution and GMFCS level in writing.
- Ask when hip surveillance starts and how often X-rays repeat.
- Ask whether constraint-induced movement therapy is appropriate if one side is more affected.
- Ask what the brace is for and what it should be doing, because "wear the brace" without a goal rarely lasts.
- Refer to early intervention or the school district today.
- Apply for your state's Medicaid waiver, because of the waiting lists.
Questions to take with you
Take these with you. Write the answers down in the moment, because you will not remember them later.
For the physiatrist or neurologist
- Which muscles are the biggest problem right now, and what is the plan for each?
- Is botulinum toxin appropriate, and what will we pair it with?
- Is my child a candidate for selective dorsal rhizotomy, and what is the evidence in a child like mine?
- How do we track whether tightness is getting worse?
For the orthopedic surgeon
- What do the hip X-rays show, and what number are you watching?
- If we do nothing, what happens over the next two years?
- What is the goal of surgery: walking, comfort, sitting, or care?
- How many procedures, and what does recovery ask of us?
For the therapy team
- What is the one goal we are working on this quarter?
- How long should the brace be worn each day, and how do we know it fits?
- What should we do at home, and can you watch me do it once?

Words on this page, in plain English
- spasticity
- Muscles that are stiff and tight, and that resist being stretched quickly.
- GMFCS
- The Gross Motor Function Classification System. A five-level scale that describes how a child with cerebral palsy moves. Level I is walking without limits. Level V is being moved in a wheelchair by someone else.
- constraint-induced movement therapy
- Therapy that gently limits the stronger arm so the child has to practice with the weaker one.
- early intervention
- The public program that provides therapy and support to children under 3 with delays or diagnosed conditions. It is required by federal law.
- Medicaid waiver
- A state program that lets a child get Medicaid based on their own needs and income rather than the family's. Many have waiting lists.
