自閉スペクトラム症児の反応時間および微細運動協調性に対するスポーツベーストレーニングプログラムの影響：パイロットスタディ

Children with autism spectrum disorders (ASD) are generally less involved in physical activity and sport. Therefore, the present pilot study aimed at determining the effect of a sport-based training program on motor coordination development and functioning in children with ASD.

Twenty children with ASD (age: 8.7 ± 1.6 years, 5 females) were included in a sport-based training program for 6 months. Participants were free to select their own sport discipline. Before and after the program, reaction time was evaluated using a simple (by identifying the targeted stimulus) and a complex (by discriminating the targeted stimulus among confounding signals) reactive test, while fine and gross motor coordination was assessed by transferring pennies, jumping in place (same sides synchronized), tapping feet and fingers (same side synchronized), and the Flamingo test.

The analysis showed a significant reduction (p = 0.016, d = 0.16) in complex reactive test (pre: 15.8 ± 14.8 s; post: 13.6 ± 11.1 s) and a significant improvement in transferring pennies test (pre: 6.3 ± 3.4 pt.; post: 7.8 ± 3.8 pt.; p = 0.034, d = 0.42). Furthermore, two of the low-functioning children, who did not perform any motor test before the program, were able to complete both reactive tests and transferring pennies test. No significant differences emerged for the remaining tests.

A sport-based extra-curricular program improved reaction time and fine motor coordination in children with ASD. The complex reactive and transferring pennies tests were particularly effective in detecting changes, even in low-functioning children. These findings support the promotion of diverse physical activities to aid physical and cognitive development.
