Construction and empirical study of motor skills evaluation system for 3-6 years old ASD children with body brain comprehensive evaluation

The Delphi and analytic hierarchy process methods were used to establish a motor skill evaluation system for ASD children from 3-6 years old, to assess their level of body and brain development． Eight children with mild ASD (M:F=6:2) aged 3-6 years were examined for their motor skills, physical fitness and EEG． The motor skill evaluation system includes: 4 first level indicators, 15 second level indicators and 39 third level indicators． The motor skills are divided into: body control skills (BCS) > body movement skills (BMS) > object control skills (OCS) > hand fine skills (HFS)． OCS and HFS are greatly affected by ASD disease characteristics and cognitive development． The unqualified rate of ASD children was 87.5%． ASD children showed higher power in delta waves in prefrontal and occipital cortex, theta waves in parietal, prefrontal and occipital lobes, alpha waves in parietal lobes, beta and gamma waves in left and right temporal lobes． Whole brain relative power topographic maps revealed higher energy delta and theta waves in ASD children, but lower energy alpha and gamma waves, these were correlated with ASD children’s inability to focus and to abnormal sensory processing． ASD children need comprehensive intervention and education on body and brain development, to promote their integration into school education, rehabilitation and development．
