Adaptation and Validation of a Serious Game for Motor Learning Training in Children with Cerebral Palsy

Abstract

[eng] Children with cerebral palsy (CP) present motor learning disorders and somatosensory dysfunction. Although many protocols use videogames in children with CP, few apply or examine motor learning principles. This study aims at 1) implementing therapist-user-designer collaboration in adapting a videogame to the principles of motor learning and the characteristics of users with CP, and 2) piloting the effectiveness of these adaptations by analyzing the achievement of motor learning parameters (learning rate acquisition, retention and transfer to motor and somatosensory function). Materials and Methods. Periodical interprofessional meetings conducted to the adaptation of a videogame, requiring the control of a joystick for travelling through a maze, to motor learning principles. In a pilot validation, effects in unilateral upper limb function, gross manual dexterity and somatosensory thresholds were assessed before and after 10-week training in 13 children with cerebral palsy. Results. After 10-week training with the adapted serious game, children showed learning rates above 90% and improvement in motor learning parameters along the sessions. Manual dexterity and pronation-supination of the dominant hand improved after training. No significant effects were found on somatosensory thresholds. Conclusion. Serious games are useful as motor learning tools for improving motor function in children with PC. Cooperative work among professionals and users is advisable for designing efficient videogames according to rehabilitation best practices.
