Additional Study Information: We are looking for adults with cerebral palsy who are 18 and over for ultrasound study of nerves at the wrist. We are assessing the symptoms of Carpal Tunnel Syndrome in adults with cerebral palsy. The study will involve a survey to describe their medical history, procedures (especially of the arms), use of adaptive equipment (such as walkers, wheelchairs), and hand positioning, a brief physical exam to assess hand movement, and positioning, and an ultrasound to assess the nerves of the wrists. The total study will be about 30 minutes to 1 hour. There are minimal risks to the study besides any mild discomfort that may occur during routine physical exam. Benefits include further knowledge of carpal tunnel symptoms in both the adult and potentially the cerebral palsy population as whole. We hope that by assessing carpal tunnel syndrome further, we can provide improved management of pain in those with cerebral palsy.
