This paper describes the sprint running of selected Class 6, 7, and 8 international-level athletes with cerebral palsy (CP), contrasts their biomechanical characteristics with those reported for nondisabled runners, and delineates discriminating biomechanical parameters among classes. Subjects included 17 male and female Class 6, 7, and 8 athletes with CP who competed in international competition and were finalists or semifinalists in sprint events. High speed films were taken, and data reduction was performed. It was concluded that (a) elite Class 6, 7, and 8 athletes with CP descriptively differ from findings reported in the nondisabled literature on variables of stride length, velocity, ratio of support to nonsupport time, time of forward swing, trunk angle, hip angle, angle of touchdown, and stride time (females only); (b) athletes with CP differ (right-side values only) between classes for hip range of motion, hip velocity, knee and elbow range of motion, and trunk angle average; and (c) distinguishing biomechanical characteristics exist between the more involved and noninvolved or less involved sides for hip velocity, angle of touchdown, and hip, knee, ankle, and shoulder range of motion.
