Abstract
The purpose of the study described here was to develop and feasibility test the Rutgers Ankle CP, aimed at ankle strengthening and improved control for children with cerebral palsy (CP). The system was an upgrade in hardware (new foot attachment, new robot controller) and software (new games and programming language) of the earlier Rutgers Ankle in order to permit training of children with CP. The new Rutgers Ankle CP was used to train ankle strength and motor control in a 7 year old boy with CP during 36 rehabilitation sessions (12 weeks, 3 times/week). Assessments for impairment, function and quality of life were taken before and after training. Results indicated improvements in both strength and motor control. Gait function improved substantially in ankle kinematics, speed and endurance. Overall function (GMFM) indicated improvements that were typical of other ankle strength training programs. Quality of life increased beyond what would be considered a minimal clinical important difference. While these results are only for a single participant, they are very encouraging toward improving the function and quality of life of children with cerebral palsy. Further research with a larger number of participants is planned.
