Peer reviewed Peer reviewed
Miyahara, Motohide; Tsujii, Masatsugu; Hori, Miwako; Nakanishi, Kazunori; Kageyama, Hidenori; Sugiyama, Toshiro – Journal of Autism and Developmental Disorders, 1997
A study compared the motor coordination of 26 Japanese children (ages 6-15) with Asperger syndrome and 14 with learning disabilities using the Movement Assessment Battery for Children. Although no relationship was found between intellectual and motor function, both groups demonstrated motor delay. Children with autism had poorer ball skills. (CR)
