Effect of Group Setting on Gross Motor Performance in Children 3-5 Years Old with Motor Delays

Influence of Modified Instructions on Locomotion Subtest Scores Using the Peabody Developmental Motor Scales, Second Edition

PURPOSE

The current study assessed whether changes in verbal and visual cues used to clarify requirements of the task would result in significant score differences on the Locomotion subtest of the Peabody Developmental Motor Scales, Second Edition (PDMS-2), in children aged 2.5 to 5 years.

METHODS

The Locomotion subtest of the PDMS-2 was administered twice, 2 to 10 days apart, to 37 children. Age-matched and gender-matched groups received instructions in both standardized and modified formats, where order depended on group assignment.

RESULTS

Instruction type resulted in a significant change in Locomotion scores with a medium effect size and no significant interactions between instruction type and age or between instruction type and test order.

CONCLUSIONS

Findings suggest instruction modifications using altered verbal and visual cues change PDMS-2 Locomotion subtest scores in children with typical development. These results support previous literature indicating that normative scores should not be reported if modifications were used during testing.

A Follow-Up Study of Motor Skill Development and Its Determinants in Preschool Children from Middle-Income Family

We tracked the motor skill development of young children aged 3-6 years and investigated the influence of middle-income home environment on the development of motor skill. 268 children were selected from kindergartens in Beijing. The Test of Gross Motor Development (TGMD) tool was used to test the development of locomotor and object-control skills (LS and OS), and a survey of children's behaviour and home environment was conducted. During the follow-up, the LS and OS of children aged 3-6 years continued to grow, with an annual growth rate of 20% and 30%. Five LS indicators and two OS indicators were significantly higher in the 3-4-year group than in the 4-5 and 5-6-year groups (p < 0.01). The age-sex trend model showed that girls' locomotor skill developed at a significantly higher rate than that of boys (β = 6.3004 and 4.6782, p < 0.001). Three-year-old boys performed significantly better than girls on object-control motor skill (p < 0.05). Factors affecting the rate of children's motor skill development in middle-income families included the frequency of playing with friends (β = 0.133, p = 0.032) and the frequency of bicycling, skateboarding, dancing, running, and jumping (β = 0.041, p = 0.042). Family income, parents' education level, and family activity area did not significantly affect the growth rate of motor skills. For middle-income families, the improvement of material environment at home like more playing spaces and toys did not speed up the motor development, while more opportunities to play with friends and engage in a variety of sports activities could promote children's motor skill development.
