Brief Summary:
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.

Condition or disease
Cerebral Palsy

Detailed Description:
The investigators are proposing a prospective, longitudinal, cross-sectional, and patient-centered outcome study of walking ability and current health status to investigate important health outcomes that impact the quality of life, participation, and activity on adults with cerebral palsy who took part in a gait analysis during childhood at the Center for Gait and Movement Analysis (CGMA). The goal is to see whether their health and walking ability has changed since leaving the Children's Hospital Colorado (CHCO) system and understand if there is a relationship between maintaining proper walking ability and health status. The investigators are including the measure of health outcomes to better understand if a decline in walking ability relates to a decline in health status. The first aim is to study the walking ability of adults with cerebral palsy by comparing their results of a gait analysis to the same results collected when they were children. The second aim is to study the presence of heart disease risk factors by testing each participant's blood levels of lipids, glucose, and insulin. The investigators will also measure each participant's blood pressure. The third aim is to study the relationship(s) between inflammatory markers, neurotrophic factors, and pain and fatigue levels. The investigators will measure inflammatory markers through a blood test and pain and fatigue levels through standardized assessments. The fourth aim is to study each participant's mental health. The investigators will measure this through standardized psychological assessments. The fifth aim is to study each participant's self-perceived health and quality of life as well as employment status. The investigators will measure these levels also through standardized assessments.

Cerebral Palsy
Patients with cerebral palsy who were seen at the Center for Gait and Movement Analysis (CGMA) at Children's Hospital Colorado as children.

Primary Outcome Measures :
  1. Change from baseline Instrumented Gait Analysis (IGA) at up to 15 years [ Time Frame: baseline and up to 15 years ]
    Kinematics - joint angles and positions during over-ground walking. Kinetics - forces measured from force plates during over-ground walking. Gait Deviation Index - overall gait performance score measured from kinematics. Electromyography - measure of muscle activity during over-ground walking. Physical Exam - measure of joint range of motion and muscle strength.

Secondary Outcome Measures :
  1. Metabolic, Inflammatory, and Neurotrophic Markers Blood Samples [ Time Frame: one time-point cross-sectional study ]
    Blood will be drawn during 1 study visit after fasting for 12 hours. Several different blood analyses will be run on the sample. Blood will not be banked.

  2. Fatigue Measure [ Time Frame: one time-point cross-sectional study ]
    Muscle fatigue will be measured by the Moreau Fatigue Index. This test is performed by doing repeated maximum voluntary concentric knee flexion and extensions at 60 degrees/sec for 35 repetitions.

  3. NIH Patient Reported Outcomes Measurement System (PROMIS) and Health-Related Quality of Life [ Time Frame: one time-point cross-sectional study ]
    Questionnaire measures of patients symptoms, functioning, and health-related quality of life.

  4. Employment Status [ Time Frame: one time-point cross-sectional study ]
    Demographic data collection using a questionnaire.

  5. The World Health Organization Disability Assessment Schedule (WHODAS II) [ Time Frame: one time-point cross-sectional study ]
    Instrument providing a global measure of disability across six domains.

  6. Self-Efficacy [ Time Frame: one time-point cross-sectional study ]
    General Self-Efficacy Scale-12 (GSES-12) assess a general sense of perceived self-efficacy with th eaim to evaluate coping with daily hassles as well as adaptation after experiencing stressful life events

  7. Life Style Assessments [ Time Frame: one time-point cross-sectional study ]

    Self-Rated Abilities for Health Practices Scale (SRAHP) - 28-item 5-point scale to measure self-perceived ability to implement health-promoting behaviors.

    Comprehensive Health Assessment Motivation Program (CHAMP)/Health & Wellness Passport - checklist of daily lifestyle and fitness choices that contribute to individuals personal success.

  8. Cognitive Battery [ Time Frame: one time-point cross-sectional study ]

    Subtests of Wechsler Adult Intelligence Score IV/Wechsler Memory Scale IV (WAIS IV/WMS IV) - standardized psychological evaluation.

    Verbal Fluency - subject generates as many words belonging to one semantic category.

    NIH Toolbox Cognitive Battery - computerized adaptive test principles to measure cognitive function.
