The analysis of monosynaptic Hoffman’s reflex (H-reflex) involves recording the response to electrical stimulation of Ia-afferent fibers from the muscle spindle. The H-reflex can be used as a probe to study spinal neuronal pathways and mechanisms at rest and during movement in humans. The purpose of this study was to analyze the feasibility of the assessment of the H-reflex in people with Down syndrome (DS), and to compare it between adult dancers and non-dancers with and without DS. Twenty-five participants were included and divided into four groups (6 nondancers and 6 dancers with DS and, 7 non-dancers and 6 dancers without DS). The H-reflex was recorded at the level of the soleus muscle in its central area. We analyzed the H response in three different conditions: decubitus prone, static standing position with open eyes and closed eyes. Non-dancers with DS showed a faster H-reflex latency than both groups without DS (all p < .005). In the present study, we provide evidence of the feasibility of eliciting the H-reflex in adults with DS. Interestingly, the H-reflex was present in decubitus position but not in standing position in most non-dancers with DS and dancers without DS. The data from this study can help to perform future research in adults with DS and the development of full-scale studies to analyze this variable in adults with intellectual disability with and without DS.

 Electromyographic analysis of ankle muscles in young adults with Down syndrome before and after the implementation of a physical activity programme based on dance Núria Massó-Ortigosaa,, Lourdes Gutiérrez-Vilahúa, Lluís Costa-Tutusausa, Guillermo R. Oviedob, Ferran Rey-Abellaa a Blanquerna School of Health Science, University Ramon Llull, Barcelona, Spain b Blanquerna Faculty of Psychology, Education and Sports Sciences, University Ramon Llull, Barcelona, Spain Received 15 June 2017; accepted 6 November 2017 Available online 21 December 2017 KEYWORDS Electromyography; Postural control; Down syndrome; Standing position; Dance Abstract Introduction: People with Down syndrome have difficulties in postural control and exhibit dif-ferences 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 with-out 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 dif-ferences 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. © 2017 FC Barcelona. Published by Elsevier Espa˜na, S.L.U.
