Children's Health

Most of the time, a doctor can predict many of the long-term physical effects of CP when a child is 1 to 3 years old. But sometimes such predictions are not possible until a child reaches school age when learning, communication skills, and other abilities can be measured.

Some children need repeated testing that may include:

• X-rays, to check for loose or dislocated hips. Children with CP are usually X-rayed several times during ages 2 to 5. A child will also have an X-ray any time he or she complains of hip pain or has other signs of dislocated hips, such as unusual leg or knee movements. Spinal X-rays also are done to look for curves in the child's spine (scoliosis).
• Gait analysis, which helps identify problems and guide treatment decisions.

Additional tests may be needed, depending on the child's symptoms or other conditions that are present.
