Abstract
Background: Children and adolescents with intellectual disabilities (ID) are characterised by deficits in fundamental movement skills (FMS). In youth with typical development, motor skill interventions have been recognised as an efficient means to improve FMS. However, the effects of these interventions among youth with ID have not yet been systematically reviewed.Purpose: The purpose of the present systematic review was to summarise the findings from studies pertaining to the effects of motor skill interventions designed to improve FMS in children and adolescents with ID.Method: A systematic literature search (without year restriction) was performed in 12 databases. Studies in press or published in English in a peer‐reviewed journal were included if: (1) participants were youth with ID aged 5 to 22; (2) motor skill interventions aimed to improve one or several FMS; and (3) they were experimental, quasi‐experimental or pre‐experimental. The Physiotherapy Evidence Database scale was used to assess the quality of the studies.Results: Through the search strategy, 1083 articles were identified, and 14 studies published between 1969 and 2018 met the inclusion criteria. In studies with children, motor skill interventions successfully improved balance skills and overall FMS, whereas mixed and inconclusive results were found for locomotor skills. In studies with adolescents, motor skill interventions were shown to successfully improve balance skills. However, none of the motor skill interventions reviewed focused on locomotor and object control skills.Conclusions: The reviewed motor skill interventions were effective in improving balance skills in both children and adolescents with ID as well as overall FMS in children with ID. Conversely, the effects of motor skill interventions targeting locomotor and object control skills remain unclear. Therefore, given the relatively small number of studies and their limitations, the present findings need to be interpreted with caution, and further rigorous studies are necessary.
