“…Since hypotonia is present in individuals with DS, this causes the muscle to perform a slow and/or ineffective contraction (Corrêa, Oliveira, Oliveira, & Corrêa, 2011). Electromyographic data of this study demonstrate that gluteus medius and tensor fascia latae, who behaved in a similar way considering muscle activation, showed significant difference at time IR between the evaluated sessions for DG and HG, and at time FR for DG.…”

ABSTRACT. Hippotherapy is a therapeutic method that uses the horse's movement to achieve functional results in practitioners with Down syndrome (DS), who present motor and neurophysiological changes that affect the musculoskeletal system. Evaluating the motor behavior related to the control and the improvement of muscle activation in practitioners with Down syndrome subjected to hippotherapy. 10 practitioners were divided into two groups: Down Group (DG) -practitioners with DS, and Healthy Group (HG) -practitioners with no physical impairment. The muscles gluteus medius, tensor fasciae latae, rectus femoris, vastus medialis, vastus lateralis, biceps femoris, tibialis anterior and gastrocnemius were evaluated by electromyography using gross RMS values, which correspond to muscle activation; the evaluations were performed on the 1 st and 10 th hippotherapy sessions (frequency: once a week), and after 2 months interval without treatment, they were performed on the 1 st and 10 th hippotherapy sessions (frequency: twice a week). It was noted that activation of the studied muscles increased with the passing of sessions, regardless the weekly frequency of attendance; however, the period without treatment resulted in reduction of this effect. Practitioners with DS presented satisfactory changes in muscle activation pattern, in learning and in motor behavior during hippotherapy sessions.Keywords: muscle activation, electromyography, hippotherapy, Down syndrome, equine assisted therapy.Avaliação eletromiográfica dos membros inferiores de pacientes com síndrome de Down na equoterapia RESUMO. Equoterapia é um método terapêutico que utiliza o movimento do cavalo para alcançar resultados funcionais, realizada em praticantes com síndrome de Down (SD), que apresentam alterações neurofisiológicas e motoras que afetam o sistema musculoesquelético. Avaliar o comportamento motor relacionado ao controle e melhora a ativação muscular em praticantes com SD submetidos ao tratamento equoterapêutico. Participaram dez praticantes divididos em dois grupos: grupo Down (GD) -praticantes com SD, e grupo Saudável (GS) -praticantes sem comprometimento físico. Os músculos glúteo médio, tensor da fáscia lata, reto femoral, vasto medial, vasto lateral, bíceps femoral, tibial anterior e gastrocnêmio foram avaliados por meio da eletromiografia, utilizando o valor de RMS bruto que corresponde à ativação muscular, e as avaliações foram realizadas na primeira e décima sessões de equoterapia (frequência: 01 vez por semana); e após intervalo de dois meses sem tratamento, foi realizada na primeira e décima sessões de equoterapia (frequência: 02 vezes por semana). Observou-se que a ativação muscular dos músculos estudados aumentou com o passar das sessões, independente da frequência semanal de atendimento; mas o período sem tratamento resultou em redução deste efeito. Os praticantes com SD apresentaram mudanças satisfatórias no padrão de ativação muscular, na aprendizagem e no comportamento motor no decorrer das sessões de equoterapia.Palavras-chave: ativa...

“…Although the increased rates of hypermetropia may be a significant factor resulting in the increased rates of strabismus, Cregg et al (2003) reported a lack of a statistical association between strabismus and hypermetropia in their longitudinal study (p = 0.539, n = 55, representing approximately just 0.14% of the UK population of individuals with Down syndrome). Given the lack of association, it was theorised that an aspect of the aetiology may be as a result of hypotonic extraocular muscles, congruous in the context of the generalised hypotonia of individuals with Down syndrome (Corrêa et al 2011). Considering that the manifest strabismus may not be corrected with spectacle lenses, individuals may wish to consider strabismus surgery to improve their ocular alignment.…”

Background and Purpose: There is a high rate of strabismus, in particular esotropia, in children with Down syndrome or developmental delay, which frequently requires surgical correction. A paper in 1994 advocated that the surgical dose be adjusted due to an altered response in these children. The aim of this literature review is to evaluate the available evidence to establish whether an altered surgical approach is required in either population. Methods: A literature review was conducted using PubMed and Web of Knowledge. Only English language papers were eligible for inclusion. The papers were collated in chronological order for analysis, and their references searched for further relevant papers. Forward citation searches were also undertaken. Results: A 2 × 2 comparison is made between publications on Down syndrome (in isolation) and developmental delay populations (including Down syndrome) with adjusted versus non-adjusted surgery. Published surgical success rates on esotropia from unaltered surgical doses range from 62.0%-85.7% (four papers) in the Down syndrome cohort, with none of the adjusted surgeries having a successful outcome. Surgical success rates from adjusted surgical doses in developmental delay cohort range from 37.5%-86.0% (seven papers), with one unadjusted surgical success rate of 76.0%. The results across the studies are summarised in a table and discussed. Conclusions: An exaggerated surgical effect in individuals with developmental delay has been reported, and this population may benefit from a reduced surgical dose. Published research does not support giving a reduced surgical dose in individuals with Down syndrome, but more research needs to be done to make a definitive conclusion.

“…However, the effects of electrostimulation are grounded on different theoretical bases, such as the assumption that direct stimulation of the motor nerves causes the muscles to perform rhythmic contractions (12,13) . In this context, electrostimulation can contribute to the treatment of individuals with DS considering the hypothesis that the presence of hypotonia in these individuals causes muscles to perform slower and/or ineffective contractions, thus leading to shorter response time.…”

Purpose Investigate and measure the effects of electrostimulation on the orofacial musculature and on the chewing, breathing and swallowing functions of individuals with Down syndrome. Methods Study participants were 16 individuals with Down syndrome (six males and 10 females) from an institutional extension project aged nine to 25 years. Speech-language pathology assessment was performed using the protocol of Orofacial Myofunctional Evaluation with Scores (OMES) pre- and post-intervention. This protocol comprised eight weekly electrostimulation sessions. Functional Electrical Stimulation (FES) current was used at a frequency of 10Hz in warm-up and 30Hz in application, intermittent stimulation (cycling pulses) with ON-time of 5s and OFF-time of 10s common to both stages, and pulse width of 200μs in warm-up and 250μs in application. Results Significant differences were observed between pre- and post-application of FES regarding cheek appearance (flaccidity and arching), tongue mobility (right and left laterality), and musculature behavior during performance of functions of the stomatognathic system: respiration, deglutition (lip behavior), and mastication (bite and trituration). Conclusion Effects of electrostimulation associated with masticatory training of the masseter muscles were statistically identified, with functional gains in chewing, breathing and swallowing performance in individuals with Down syndrome.
