Abstract

Introduction: People with Down syndrome have difficulties in postural control and exhibit differences in the displacement of their centre of pressure and in muscle activity compared with the general population. Previous research has shown that centre of pressure displacement is less depending on visual conditions in people with Down syndrome, although improved balance has been observed following specific physical activities based on dance. The aim of the project was to assess the effect of a dance-based physical activity programme on muscle activity in young adults with Down syndrome. Material and methods: Eleven participants with Down syndrome and eleven participants without Down syndrome as the control group followed an 18-week dance programme. Surface electromyography was used to assess ankle muscle activity before and after completion of the programme in open and closed eyes conditions. Results: We observed a higher level of muscle activation in Down syndrome group. They showed minor differences between different visual conditions than control group. No significant differences were seen in pre- and post-training in Down syndrome group. Nevertheless, less differences were observed between both groups after training than before. Conclusions: Although no significant differences were observed in Down syndrome group after training, differences between groups were decreased. These could be related to some postural adaptations. In the future, it will be interesting to increase the sample and also analyze the position of centre of pressure in relation to feet.
