What will happen in the study?

This study involves up to three visits on separate days, lasting about 3 hours each. The first visit will take place at the same time the child/teen with CRPS is visiting for treatment. The second visit will be scheduled after treatment ends. The third visit will be scheduled 6 months after treatment ends. Here are some of the things that will happen in this study:

Children and teens with CRPS will:

• Complete questionnaires about your feelings, relationship with your parents, your health, your CRPS and your CRPS treatments
• Complete tasks which include listening to different sounds, looking at checkerboard images, and doing movements with your fingers
• Be placed in a machine called an MRI to view your brain. The machine is like a giant tube which is open at both ends. You will be in that tube for one-and-a-half hours. Pillows will be used to keep your head still. We will take several breaks, but you will need to stay in the tube during these breaks.
• Provide a urine sample to test for drugs. Your doctor and parent will be informed if the test result is positive.
• Complete a pregnancy test if you are a sexually active female. Your doctor and parent will be informed if the test result is positive

Parents will complete a series of questionnaires during each visit that ask about your feelings, your relationship with your child, your health, your child’s pain condition and your child’s overall health.
