Measuring motor skills in Finnish children with intellectual disabilities.

This investigation examined differences in motor skill development between Finnish children (12 boys, 8 girls) with mild intellectual disability and typically developing Finnish children between the ages of 7 and 11 years. Ulrich's Test of Gross Motor Development (TGMD) assessed the performances of 20 children with intellectual disability and an age- and sex-matched sample of 20 children without disabilities. Videotaped performances were assessed by the authors who were very familiar with the TGMD-2. The group with intellectual disability performed at a statistically significantly lower level on the Gross Motor Quotient, Locomotor, and Object Control subtests of TGMD-2, compared to the group without intellectual disability. The delay was equivalent to 3 to 4 years behind the Finnish normative group in gross motor development. In five out of 12 subtests, the group with intellectual disability achieved 0% mastery. Given low gross motor skills, children with intellectual disability require additional fundamental motor skill training in their active school or free time.
