Intervention study of Active Video Games on intellectual disabled children’s physical activity level, motor ability and physical fitness

    Project: Research project

    Project Details


    Background: Children with intellectual disabilities (ID) are more vulnerable to obesity when compared to the normal children (Getchell et al., 2012; Maiano, 2011). Active video games (AVGs) on physical activity (PA) behavior have attracted academic interest and exploration since 2000. It has been demonstrated that an intervention with AVGs is compatible with the school setting and behavioral change in health and PA (Lau, et al., 2015). However, special populations such as ID children and their needs have been neglected in this area (Martins, Carvalho & Soares, 2011). ID children’s PA behavior, motor ability and physical fitness is still an under-explored area.

    Aims: To determine the effect of a prescribed AVG intervention on ID children’s PA levels (sedentary, light, moderate, and vigorous), motor ability, and physical fitness. The intervention effects in children with different intellectual disability categories (i.e., mild, moderate, severe and profound) will be also explored.

    Design: A standard two-arm parallel, single-blinded, randomized control cluster trial. Schools: Participants will be recruited from six special schools in Hong Kong (two mild, two moderate and two severe & profound categories). Schools with same intellectual disability categories will be randomly assigned into intervention group and control group. Participants: 360 Children aged 9~16 years old (180 in each group) with intellectual disabilities will be recruited.

    Intervention: ID children randomized to the intervention group will participate in an AVG intervention 60 minutes per week for 16 weeks in their PE class, in addition to their usual activity levels. The research team will prescribe updated AVG consistent with moderate-vigorous intensity.

    Control: The control group will continue with usual PA alone and will not receive the AVG intervention. Analysis: Repeated measures mixed model (2 groups X 2 time points (16-week post- test and 8-week follow up test)) by SPSS 23.0 will be used to investigate the intervention effect on primary and secondary outcomes, adjusting for baseline characteristics and correlation between repeated observations.

    Significance: This will be the pioneering study to provide definitive evidence for the impact of a prescribed AVG intervention on ID children’s PA level, motor ability and physical fitness. If effective, this research will provide significant evidence from the innovative method to inform health professionals and PE teachers how to incorporate AVG to enhance physical active behaviors, motor ability and physical fitness in ID children. Finally they may be able to enjoy a better quality of life.
