Cerebral Palsy Adult Transition Longitudinal Study

The purpose of this study is to investigate longitudinally, the walking ability of individuals with cerebral palsy who are transitioning into adulthood and to cross-sectionally examine the health status of these individuals in the context of their walking ability. Young adults who received instrumented gait analysis (IGA) as children will show significant decreases in overall gait performance, as measured by kinematics, kinetics, temporal-spatial parameters, and gait deviation index, compared to their last childhood IGA.

Inclusion Criteria: * Male and female adults (aged 18 years or older) with cerebral palsy (CP) * Adults with CP who are part of the CGMA data registry * Adults with CP who have previously participated in an IGA at the CGMA * Adults with CP who are able to walk (with or without assistance) three times down a \~35 foot walkway at a comfortable and self-selected pace * Adults with CP who are able to give informed consent, or have a legally authorized representative to give informed consent * Adults with CP who are able to understand and communicate in English or Spanish (medical interpreters will be utilized for this study when needed) * If medicated, adults with CP will need to be on a stable medication regimen for at least six months prior to study enrollment (including non-steroidal anti-inflammatory drugs (NSAIDs)) * Adults with CP who are able to devote sufficient time to participate in a health/physical exam, respond to questions asked during assessments, and participate in an IGA * Adults with CP who have no recent history of seizure or blackout Exclusion Criteria: * Male and female children (aged 17 years or younger) with CP * Adults with CP who have never participated in an IGA at the CGMA * Adults with CP whose mobility is impaired to the point of being unable to move (even with assistance) * Adults with CP who are taking any medication(s) that might interfere with the ability to move * Adults with CP who are unable to devote sufficient time to participate in a health/physical exam, respond to questions asked during assessments, and participate in an IGA * Adults with CP who have any medical issue impacting performance
