Abstract
Background: Wii-based interventions have shown significant benefits in motor learning for children with developmental coordination disorder (DCD); however, studies comparing the effects of Wii interventions versus matched non-Wii interventions, such as task-specific training (TST), are scarce. Objective: We compared motor learning in children with DCD who participated in 12 sessions of Wii-based training and those participating in 12 closely matched non-Wii TST sessions as well as when the highest improvements in performance occurred. Methods: In total, 32 children with DCD (16 per group) were randomly allocated to receive the Wii intervention or TST during 12 sessions. Motor learning was assessed in 3 consecutive phases during the intervention and was determined by the mean of the games scores obtained in the: (1) first 4 sessions, (2) intermediate 4 sessions, and (3) last 4 sessions. Six different tasks (table tennis, frisbee, archery, bowling, tightrope walking/balance beam, and marble balance/balance disc) were performed in every session. Each session lasted 42 min (time on task). Results: Wii training and TST elicited improvements in motor learning, as assessed by increased scores with the frisbee and marble balance/balance disc tasks. However, Wii training elicited better performance in the archery and bowling tasks, whereas only TST elicited improvements in the balance beam and table tennis tasks. Conclusion: Wii training is not always superior to non-Wii training, and improvements are based on the type of task trained. Thus, each type of intervention benefits a certain skill.
