The effect of dual-task training on postural and cognitive performances in adolescents with down syndrome

Abstract

BackgroundThe dual task training (DTT) has been shown to improve postural and cognitive performances in many populations. Therefore, it seems of interest to explore the effect of such training modality in individuals with Down syndrome (DS) presenting both cognitive and postural deficits. AimsThis study explored the effect of a DTT compared to a single task training (STT) on postural and cognitive performances in adolescents with DS. Methods and proceduresThe center of pressure velocity (CoPVm) and the cognitive performance in the selective word recall test were recorded under single task (ST) and DT conditions before and after 8 weeks in the STT group (STTG), the DTTG and the control group (CG). Outcomes and resultsBefore training, CoPVm values increased and cognitive performances decreased (p < 0.001) during the DT compared to ST conditions in all groups. After training, CoPVm decreased (p < 0.001) in the DTTG and the STTG under the ST conditions. However, under DT conditions, these values decreased (p < 0.001) only in the DTTG. The cognitive performance increased (p < 0.001) only in the DTTG in both ST and DT conditions. ConclusionThe DTT is strongly recommended to improve both postural and cognitive performances in individuals with DS notably in DT conditions.
