Resumen La danza es una actividad físico-deportiva y artística idónea para el desarrollo integral del alumnado y puede considerarse como promotora de inclusión. Por ello, el objetivo de este estudio fue realizar una revisión narrativa relacionada con los beneficios que aporta la danza en el alumnado con Síndrome de Down (SD) en la etapa de educación infantil. Para realizar la búsqueda de los documentos, se emplearon las palabras clave: "Child Education", "Dance" y "Down Syndrome". Los manuscritos fueron buscados en las bases de datos Web of Science, Scopus, SPORTDiscus y PubMed, hasta enero de 2023. Para ajustar la búsqueda al objeto de estudio, se estableció una serie de criterios de inclusión: i) cualquier tipo de documento científico relacionado con la temática; ii) manuscritos que indiquen, en el cuerpo del texto, al menos una descripción de los alumnos con SD de una longitud mínima de 50 palabras; iii) documentos realizados en inglés, español y/o portugués; y, iv) manuscritos que permitan obtener el texto completo; se obtuvo un total de 9 documentos. Los resultados mostraron una escasez de documentos en relación con el ámbito de estudio, como consecuencia de ser una temática muy específica. Asimismo, los manuscritos incluidos en esta revisión reportan que los beneficios que podrían obtenerse de la danza para el alumnado con SD están relacionados con la conciencia y el control postural, la mejora de aspectos sociales y mejoras a nivel cognitivo y emocional, así como el disfrute. Por ello, se recomienda ampliar el número de investigaciones futuras relacionadas con la danza en el sistema educativo y, concretamente, en la etapa de educación infantil, debido a los múltiples beneficios que aporta al alumnado con discapacidad.

Abstract Dance is a physical/sports and artistic activity appropriate to the comprehensive development of students, and can be considered as a means to promote inclusion. Thus, the objective of this study was to carry out a narrative review related to the benefits of dance in students with Down Syndrome (DS) in the child education stage. In order to carry out the search of documents, the keywords "Child Education", "Dance", and "Down Syndrome" were used. Manuscripts were searched in the Web of Science, Scopus, SPORTDiscus and PubMed data bases, up to January, 2023. In order to adjust the search of the object of study, a series of inclusion criteria was established: i) any type of scientific document relating to the topic; ii) manuscripts indicating, within the text body, at least one description of the students with DS that is at least 50 words in length; iii) documents written in English, Spanish and/or Portuguese; and iv) manuscripts that allow to obtain the full text. A total 9 documents were obtained. The results showed a scarcity of documents concerning the domain of study, as a result of this being a very specific topic. Similarly, the manuscripts included in this review report that the benefits that could derive from dance for students with DS have to do with posture awareness and control, the improvement of social aspects and improvements of a cognitive and emotional nature, as well as enjoyment. Therefore, it is recommended to expand the number of future research projects related to dance in the educational system, and concretely in the child education stage, due to the multiple benefits this brings to students with disabilities.

Effect of hippotherapy on balance, functional mobility, and functional independence in children with Down syndrome: randomized controlled trial.

Impaired muscle strength, proprioceptive and vestibular deficits, and orthopedic dysfunction are common disorders associated with Down syndrome (DS). Hippotherapy uses the horses' multidimensional movement to improve posture, balance, and overall function, both motor and sensory. Research evidence supports hippotherapy as an effective, medically recognized intervention for the rehabilitation of gross motor skills. The aim of this study was to determine the effect of hippotherapy on balance, functional mobility, and functional independence in children with DS. Thirty-four children with DS were randomly assigned to the experimental (hippotherapy) and control groups after the initial assessment. Both groups received physiotherapy including balance exercises, and the experimental group also received hippotherapy as an integrative therapy. Pediatric Balance Scale (PBS), Timed Up and Go Test (TUG), and Functional Independence Measure for Children (WeeFIM) were used before and after the intervention. Baseline outcome measures (PBS, TUG, WeeFIM) were statistically similar between groups (p > 0.05). After the intervention, PBS and TUG scores improved in both groups (p < 0.05). On the other hand, WeeFIM scores improved just in the hippotherapy group (p < 0.05).   Conclusion: Therefore, providing hippotherapy as an integrative therapy to physiotherapy will be more effective in improving the functional independence of children with DS.    Trial registration: NCT05297149 (March 2022, retrospectively registered). What is Known: • Hippotherapy has an improvement effect on balance and functional independence in different diseases and age groups, but the evidence is limited in DS. • There is limited evidence about the effect of hippotherapy on functional mobility in different diseases and age groups, but there is no evidence in DS. What is New: • Hippotherapy is a safe and effective approach to support improvement in functional independence in children with DS.

The effectiveness of dance movement therapy for individuals with Down syndrome: a pilot randomised controlled trial.

BACKGROUND: Individuals with Down syndrome (DS) exhibit deficits in static and dynamic balance abilities and maladaptive functions. This study aimed to determine the effectiveness of dance movement therapy (DMT) group intervention in individuals with DS. METHODS: The 31 participating individuals with DS, aged 5-29 years, were randomly divided into intervention (n = 16) and control (n = 15) groups. Posturography was used for static balance measurement, timed up and go test for dynamic balance measurement and the Achenbach System of Empirically Based Assessment (ASEBA) questionnaire for adaptive function and behavioural problem measurement in participants before and after the DMT interventions. The intervention group underwent 60-min DMT intervention once a week for 10 times, while the control group had usual daily activities. RESULTS: The results revealed a statistically significant difference and large effect sizes in dynamic balance [(f(1, 29) = 4.52, P = 0.04, ηp 2 = 0.14)] in the intervention group compared with the control group. There were no statistically significant differences in static balance and ASEBA scores between the groups. CONCLUSIONS: This study found that the DMT interventions helped to improve the dynamic balance in individuals with DS.

State-of-the-art therapy for Down syndrome.

In the last decade, an important effort was made in the field of Down syndrome to find new interventions that improve cognition. These therapies have added to the traditional symptomatic treatments and to the drugs for treating Alzheimer disease in the general population repurposed for Down syndrome. Defining next-generation therapeutics will involve biomarker-based therapeutic decision-making, and preventive and multimodal interventions. However, translation of specific findings into effective therapeutic strategies has been disappointingly slow and has failed in many cases at the clinical level, leading to reduced credibility of mouse studies. This is aggravated by a tendency to favour large-magnitude effects and highly significant findings, leading to high expectations but also to a biased view of the complex pathophysiology of Down syndrome. Here, we review some of the most recent and promising strategies for ameliorating the cognitive state of individuals with Down syndrome. We studied the landscape of preclinical and clinical studies and conducted a thorough literature search on PubMed and ClinicalTrials.gov for articles published between June 2012 and August 2022 on therapies for ameliorating cognitive function in individuals with Down syndrome. We critically assess current therapeutic approaches, why therapies fail in clinical trials in Down syndrome, and what could be the path forward. We discuss some intrinsic difficulties for translational research, and the need for a framework that improves the detection of drug efficacy to avoid discarding compounds too early from the companies' pipelines.

A pilot randomised controlled trial on the effectiveness of infant massage on the acceptance, commitment and awareness of influence in parents of babies with Down syndrome.

BACKGROUND: The emotional state of parents of babies with Down syndrome affects their babies' development and their parent-child bonding. The aim for this study was to conduct a pilot randomised controlled evaluation of the effect of infant massage on parents of babies with Down syndrome. METHODS: This pilot study compared two groups (intervention and control), each with 16 parents of babies with Down syndrome. Indices of acceptance, engagement and awareness of influence were measured at two different time points (pre-test and after 5 weeks) using the 'This Is My Baby' Interview. The allocation of families to each group was randomised. The experimental group performed infant massage, applied by the parents, for 5 weeks, every day for at least 10 min. The massage protocol was based on the methodology created by Vimala McClure. Parents in the control group received the intervention after completion of the study. RESULTS: The indices of acceptance, commitment and awareness of influence improved in the experimental group and in the control group. The 2 × 2 mixed-model analysis of variance indicates a statistically significant group-by-time interaction for all indices (P < 0.001), which was significantly higher in the experimental group than in the control group. CONCLUSIONS: The application of infant massage, by parents to their babies, improves the rates of acceptance, commitment and awareness of influence of parents of babies with Down syndrome in the short term.

Brain activity and upper limb movement analysis in children with Down syndrome undergoing transcranial direct current stimulation combined with virtual reality training: study protocol for a randomized controlled trial.

BACKGROUND: Children with Down syndrome have poorer functional and sensory skills compared to children with typical development. Virtual reality (VR) training could help improve these skills. Moreover, transcranial direct current stimulation (tDCS) has achieved promising results in terms of enhancing the effects of physical and sensory therapy by modulating cortical excitability. METHODS/DESIGN: Two investigations are proposed: (1) an observational study with a convenience sample consisting of children with Down syndrome (group 1-cognitive age of 6 to 12 years according to the Wechsler Abbreviated Scale of Intelligence) and children with typical development 6 to 12 years of age (group 2). Both groups will undergo evaluations on a single day involving a three-dimensional analysis of upper limb movements, an analysis of muscle activity of the biceps and brachial triceps muscles and an analysis of visuospatial and cognitive-motor variables. (2) Analysis of clinical intervention: a pilot study and clinical trial will be conducted involving individuals with Down syndrome (cognitive age of 6 to 12 years according to the Wechsler Abbreviated Scale of Intelligence). The sample will be defined after conducting a pilot study with the same methodology as that to be used in the main study. The participants will be randomly allocated to two groups: An experimental group submitted to anodal tDCS combined with a VR game and a manual motor task and a control group submitted to sham tDCS combined with a VR game and a manual motor task. The training protocol will involve 10 sessions of active or sham tDCS during memory and motor task games. Three 20-min sessions will be held per week for a total of 10 sessions. Evaluations will be performed on three different occasions: pre-intervention, post-intervention (after 10 sessions) and follow-up (1 month after the intervention). Evaluations will consist of analyses of electroencephalographic signals, electromyographic signals of the biceps and triceps brachii, and the three-dimensional reconstruction of the reaching movement. The results will be analyzed statistically with the significance level set at 5% (p ≤ 0.05). DISCUSSION: The optimization of the results obtained with virtual reality training is believed to be related to the interactive experience with a wide range of activities and scenarios involving multiple sensory channels and the creation of exercises, the intensity of which can be adjusted to the needs of children. Therefore, the proposed study aims to complement the literature with further information on tDCS and VR training considering different variables to provide the scientific community with clinical data on this combination of interventions.

Long-term stability of hypoglossal nerve stimulation for the treatment of obstructive sleep apnea in children with Down syndrome.

IMPORTANCE: Obstructive sleep apnea (OSA) occurs in 55-97% of people with Down syndrome (DS). Even after adenotonsillectomy, residual OSA often persists into adulthood due, in part, to tongue base collapse. Implantable hypoglossal nerve stimulators are being investigated in children and young adults with DS and persistent, moderate to severe OSA. However, the long-term necessity for such an intervention-especially as patients mature and voltage adjustment becomes warranted-has not been previously reported in the pediatric DS population. OBJECTIVE: To assess the long-term need for implantable hypoglossal nerve stimulators and the necessity for voltage adjustment in children and young adults with Down syndrome. DESIGN: This is a case series from an ongoing clinical trial assessing safety and efficacy of hypoglossal nerve stimulation among 42 children and young adults with DS and persistent OSA, despite adenotonsillectomy and trialed positive airway pressure (PAP) therapy. We focus here on the first 4 participants who have undergone implantation by age 13 and have completed at least 44 months of follow-up. PARTICIPANTS: 4 participants (2 male, 2 female; ages 10-13 years) with DS and persistent, severe OSA (AHI > 10 events/h) underwent hypoglossal nerve stimulator implantation and were followed for 44-58 months. SETTING: Participants completed in-lab sleep studies at baseline (before implantation), 1 year postoperatively, and 44-58 months postoperatively. During their most recent follow-up, 2 participants completed split-night sleep studies in which assessment was done with the device both on and off. INTERVENTIONS: Hypoglossal nerve stimulator implantation. MAIN OUTCOMES AND MEASURES: Stability in titrated and untitrated OSA as measured by the apnea-hypopnea index (AHI); growth measures including BMI; and quality of life as measured by the OSA-18 questionnaire. RESULTS: Compared to baseline, all 4 participants maintained reductions of at least 50% in AHI over the course of follow-up. At recent follow-up, two participants had persistent, moderate OSA despite stimulation therapy. The other two participants achieved 100% reductions in AHI with stimulation therapy; when they underwent split-night sleep studies, the severe OSA persisted with the device turned off. Improvement in OSA-18 quality of life scores was observed in three of the four participants. CONCLUSION: and Relevance: Hypoglossal nerve stimulation continues to effectively control OSA in children with DS as they mature, while their underlying untitrated OSA appears to persist into adulthood.

Meta-analysis of metabolites involved in bioenergetic pathways reveals a pseudohypoxic state in Down syndrome.

Clinical observations and preclinical studies both suggest that Down syndrome (DS) may be associated with significant metabolic and bioenergetic alterations. However, the relevant scientific literature has not yet been systematically reviewed. The aim of the current study was to conduct a meta-analysis of metabolites involved in bioenergetics pathways in DS to conclusively determine the difference between DS and control subjects. We discuss these findings and their potential relevance in the context of pathogenesis and experimental therapy of DS. Articles published before July 1, 2020, were identified by using the search terms "Down syndrome" and "metabolite name" or "trisomy 21" and "metabolite name". Moreover, DS-related metabolomics studies and bioenergetics literature were also reviewed. 41 published reports and associated databases were identified, from which the descriptive information and the relevant metabolomic parameters were extracted and analyzed. Mixed effect model revealed the following changes in DS: significantly decreased ATP, CoQ10, homocysteine, serine, arginine and tyrosine; slightly decreased ADP; significantly increased uric acid, succinate, lactate and cysteine; slightly increased phosphate, pyruvate and citrate. However, the concentrations of AMP, 2,3-diphosphoglycerate, glucose, and glutamine were comparable in the DS vs. control populations. We conclude that cells of subjects with DS are in a pseudo-hypoxic state: the cellular metabolic and bio-energetic mechanisms exhibit pathophysiological alterations that resemble the cellular responses associated with hypoxia, even though the supply of the cells with oxygen is not disrupted. This fundamental alteration may be, at least in part, responsible for a variety of functional deficits associated with DS, including reduced exercise difference, impaired neurocognitive status and neurodegeneration.

Effects of Photobiomodulation in Children with Down Syndrome and Possible Sleep Bruxism: Protocol For A Randomized, Controlled, Blind, Clinical Trial: Study protocol clinical trial (SPIRIT compliant).

Hypotonia, particularly of the masticatory and oropharyngeal muscles, is 1 of the main characteristics of Down Syndrome (DS), resulting in impaired speech, chewing and swallowing. Moreover, the complete or partial obstruction of the airways during sleep may occur due to hypotonia of the tongue, leading to snoring and sleep disorders, such as obstructive apnea and sleep bruxism. OBJECTIVE:: Analyze salivary levels of dopamine and cortisol and muscle activity before and after treatment with low-level laser therapy administered to acupoints in children with DS. METHODS:: A randomized, controlled, clinical trial will be conducted. Individuals 4 to 17 years of age with a diagnosis of DS and possible sleep bruxism will be screened at the Integrated Health Clinic of Nove de Julho University. We will evaluate orofacial dysfunction (Nordic Orofacial Test - Screening questionnaire), Masseter muscle activity during sleep will be assessed by BiteStrip and the masticatory muscles will be evaluated by electromyography (BTS TMJOINT) head posture as well as salivary cortisol and dopamine. After the evaluations, the participants will be randomized into 2 groups: Grupo 1 - treatment with low-level laser therapy at a wavelength of 808 nm; Group 2 - sham treatment (simulated laser therapy). Treatment will be conducted twice per week for a total of 12 sessions. The data will be tabulated and treated using GraphPad Prism version 7.0. The Kolmogorov-Smirnov test will be used to determine the normality of the data. Variables that fit the Gaussian curve will be expressed as mean and standard deviation. The ANOVA 2-way will be used for comparisons between the groups, with the significance level set to 5% (P < .05).ClinicalTrials registration number: NCT04211870.

Multiorgan involvement and management in children with Down syndrome.

AIM: To review multiorgan involvement and management in children with Down syndrome (DS). METHODS: A literature review of articles from 1980 to 2019 using the MEDLINE interface of PubMed was performed using the following search terms- [Down syndrome] or [Trisomy 21] AND [Cardiology] or [Respiratory] or [neurodevelopment] or [epilepsy] or [musculoskeletal] or [immune system] or [haematological] or [endocrine] or [gastrointestinal] or [ophthalmological] or [Ear Nose Throat] or [dermatology] or [renal]. RESULTS: Congenital heart disease particularly septal defects occur in over 60% of infants with DS and 5%-34% of infants develop persistent pulmonary hypertension of the newborn irrespective of a diagnosis of congenital heart disease. Early recognition and management of aspiration, obstructive sleep apnoea and recurrent lower respiratory tract infections (LRTI) could reduce risk of developing pulmonary hypertension in later childhood. Children with DS have an increased risk of autistic spectrum disorder, attention deficit disorder and epilepsy particularly infantile spasms, which are associated with poor neurodevelopmental outcomes. Congenital anomalies of the gastrointestinal and renal system as well as autoimmune diseases, coeliac disease, arthropathy, thyroid dysfunction fold diabetes mellitus and dermatological conditions are more common. Hearing and visual anomalies are also well recognised association with DS (Table 1). CONCLUSION: Children with DS are at an increased risk of multiorgan comorbidities. Organ-specific health surveillance may provide holistic care for the children and families with DS throughout childhood.

Outcomes following physical therapy incorporating hippotherapy on neuromotor function and bladder control in children with Down syndrome: A case series.

Aims: The objective of this case series was to document gross motor function, gait parameter, and bladder control outcomes following physical therapy incorporating hippotherapy in children with Down syndrome (DS). Methods: Four children between three and five years of age received eight-weekly physical therapy sessions incorporating hippotherapy. Outcome measures included the Gross Motor Function Measure-88 (GMFM-88), parental perception of function during every day activities, spatiotemporal parameters of gait and bladder control. Results: Total change scores on the GMFM-88 exceeded the standardized response mean in all four children, while scores on Dimension E improved in two children. From the mothers' perspectives, all children showed at least some improvement in walking, running, and jumping; sitting, kneeling, and standing; symmetry and comfort; balance; coordination and social interactions and there were inconsistent changes in bladder control. Only one child demonstrated changes greater than 20% in any of the gait parameters. Conclusions: Physical therapy incorporating hippotherapy may be a potential treatment to assist in improving gross motor function in children with DS, but eight sessions may not be long enough to show major improvements in gait parameters or bladder control. Further research in the form of larger controlled trials is warranted to provide more support for the intervention in those with DS.

Effect of horse riding equipment in activity of trunk and lower limb muscles in equine-assisted therapy

Equine-assisted therapy uses the horse in rehabilitation and/or education of people, such as Down syndrome(SD), cerebral palsy(PC)and intellectual disability(DI). In context, the rehabilitation program and horse riding equipment should be usedaccording to the specific characteristics of each individual, becoming an ally in the quest for excellence in equine-assisted therapy programs. The aim was to evaluate the effect of riding equipment used in equine-assisted therapy on the muscular activityof trunk and lower limb of individuals with SD, PC and DI. The study included 15 individuals equally assigned to each group: SD, PC and DIwith a mean age of 16.2 (±1.10), 16 (±1.22)e 16 (±0) years,respectively. The analysis of muscle activity was performed through surface electromyography, using four variations of horse riding equipment: saddle with and without feet supported on the stirrups and blanket with and without feet supported on the stirrups. Sigma Stat 3.5®software was used for statistical analysis.The Shapiro Wilk's test was used for normality of the data, the Bartlett test for homogeneity of the variances and the Kruskal-Wallis test for repeated measures with no normal distribution.Statistically significant differences were observed forp<0.05.The SDgroup presented a greater muscular activity of trunk and lower limbs with blanket equipment without the feet supported in the stirrups (H = 15.078, p = 0.002), as in the DI group (H=8.302, p = 0.040), while inPCgroup was the saddle with feet supported in the stirrups (H=11.137,p = 0.011). The choice of riding equipment used in equine-assisted therapy interferes differently in the pattern of muscular activation of the trunk and the lower limbs, according to the pathological processes of the practitioners. It should be an important aspect to consider when planninga treatment.

Evaluation of the masticatory muscle function, physiological sleep variables, and salivary parameters after electromechanical therapeutic approaches in adult patients with Down syndrome: a randomized controlled clinical trial.

BACKGROUND: There are many comorbidities associated with Down syndrome (DS), including obstructive sleep apnea (OSA) and masticatory muscle alteration. Muscular hypotonia, in particular, of the masticatory and oropharyngeal muscles is one of the main characteristics of individuals with DS, resulting in impairments of speech, swallowing, and mastication in these individuals. In addition, total or partial obstruction of the airways during sleep can occur due to pharyngeal hypotonia, leading to snoring and to OSA. This progressive respiratory disorder is associated with a high risk of morbidity and mortality in individuals with DS. The aim of this research is to assess the therapeutic effects of surface neuromuscular electrical stimulation (NMES), the mastication apparatus (MA), and a mandibular advancement oral appliance (OAm) with an embedded thermosensitive microchip on the functions of masticatory muscles (bilateral masseter and temporal muscles), physiological sleep variables, and salivary parameters in adult patients with DS. METHODS: The patients with DS will be randomly selected and divided into three groups (DS-NMES, DS-MA, and DS-OAm) with a minimum of 10 patients in each group. A thermosensitive microchip will be embedded in the OAm to record its compliance. The therapeutic effects on masticatory muscle function will be investigated through electromyography, a caliper, and a force-transducer device; the sleep variables, in turn, will be evaluated by means of polysomnography. The physicochemical and microbiological properties of the saliva will also be analyzed, including the salivary flow, viscosity, buffer capacity, cortisol levels (susceptibility to psychological and/or physical stress), and Pseudomonas aeruginosa levels (risk of aspiration pneumonia) in these patients. The methods determined for this study will be carried out prior to and after 2 months of the recommended therapies. DISCUSSION: The primary outcomes would be the improvement and/or reestablishment of the function of masticatory muscles and the physiological sleep variables in this target public since individuals with DS commonly present generalized muscular hypotonia and dysfunction of the oropharyngeal musculature. As a secondary outcome indicator, the impact of the applied therapies (NMES, MA, and OAm) on the salivary microbiological and physicochemical properties in DS individuals will also be assessed. Furthermore, the compliance of OAm usage will be measured through a thermosensitive microchip. TRIAL REGISTRATION: Registro Brasileiro de Ensaios Clínicos, RBR-3qp5np .

Efeito da fisioterapia aquática na força muscular respiratória de crianças e adolescentes com Síndrome de Down / Effect of aquatic physioterapy on the respiratory muscle strength of children and teenagers with Down Syndrome

A força muscular respiratória em crianças e adolescentes com Síndrome de Down é comprometida pela hipotonia generalizada que os acometem. Analisar os efeitos da fisioterapia aquática na força muscular respiratória em crianças e adolescentes com síndrome de Down. Estudo de intervenção, quasi-experimental, com amostra constituída de oito crianças e adolescentes diagnosticados com SD e média de idade de 12 anos (± 3,8). Foram realizadas 10 sessões de fisioterapia aquática, com 50 minutos de duração cada, em piscina com água aquecida. A força muscular respiratória foi avaliada a partir da pressão inspiratória máxima (PImáx) e pressão expiratória máxima (PEmáx) com auxílio do manuvacuômetro, sendo obtido seus valores antes do primeiro atendimento e após o último. Analisou-se ainda a saturação periférica de oxigênio e frequência cardíaca. Para comparação das médias antes e depois da intervenção foi utilizado o Teste T pareado. Amostra de indivíduos predominantemente do sexo feminino (75,0%), pardos (75,0%) e residentes em zona urbana (87,5%). A comparação da PImáx e PEmáx antes e após as 10 sessões de fisioterapia aquática evidenciou melhora da força muscular inspiratória e expiratória, sendo tais diferenças estatisticamente significantes (valor de p<0,01). Também foram notadas melhorias na frequência cardíaca e saturação de oxigênio (valor de p<0,05) com a intervenção. Destaca-se neste estudo que a fisioterapia aquática parece ser um recurso terapêutico eficiente para o fortalecimento da musculatura respiratória e melhora dos sinais vitais de crianças e adolescentes de com diagnóstico de Síndrome de Down.

Respiratory muscle strength in children and adolescents with Down syndrome is compromised by the generalized hypotonia that affects them. This study aims to analyze the effects of aquatic physical therapy on respiratory muscle strength in children and adolescents with Down syndrome. Material and method: A quasi-experimental study with a sample consisting of eight children and adolescents diagnosed with DS and mean age of 12 years (± 3.8). Ten sessions of aquatic physiotherapy were performed, each with a duration of 50 minutes, in a pool with heated water. Respiratory muscle strength was assessed from maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) using a manuvacuometer, and its values were obtained before the first session and after the last one. Peripheral oxygen saturation and heart rate were also analyzed. The paired T-test was used to compare the means before and after the intervention. Sample of predominantly female (75.0%), brown (75.0%) and urban residents (87.5%). The comparison of MIP and MEP before and after the 10 sessions of aquatic physiotherapy showed an improvement in inspiratory and expiratory muscle strength, and these differences were statistically significant (p <0.01). Improvements in heart rate and oxygen saturation (p value <0.05) were also noted with the intervention. In this study, aquatic physiotherapy seems to be an efficient therapeutic resource for the strengthening of respiratory muscles and improvement of the vital signs of children and adolescents diagnosed with Down's Syndrome.

Effectiveness of Animal-Assisted Therapy in the Pediatric Population: Systematic Review and Meta-Analysis of Controlled Studies.

OBJECTIVE: To synthesize the results of controlled studies evaluating the effectiveness of animal-assisted therapy (AAT) in children. METHODS: Eleven databases were searched following the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement recommendations, and references from included studies and previous reviews were examined. No date or language filters were applied. Only controlled study designs, including those using wait-list controls, that studied a specific condition or illness were included. Study quality was assessed using the Cochrane Risk of Bias Tool. RESULTS: Twenty-six studies that met the inclusion criteria were retrieved. Nine were conducted in children with autism spectrum disorders, 10 in cerebral palsy (CP), 2 in Down syndrome, 3 in pain, and 2 in other conditions. Qualitative synthesis showed a small but significant contribution of AAT to the management of these conditions. Meta-analysis showed a mean difference in improvement in the Gross Motor Function Measure-66 scale in children with CP of 1.61 (95% confidence interval [CI] -2.00 to 5.23) and a mean difference for 5-point pain scales of -0.81 (95% CI -1.32 to 0.30), both favoring AAT. CONCLUSION: Animal-assisted therapy may be useful as a complementary intervention in the management of children with CP and pain. Although results are in general positive for the management of children with Down syndrome and autism, the diversity of scales used to measure outcomes makes it difficult to establish true effectiveness. The application of simple corrective measures in the randomization process would greatly improve the quality of evidence. It is necessary to reach a consensus between AAT researchers regarding appropriate instruments to provide higher-quality evidence in further studies.

Treatment with corn oil improves neurogenesis and cognitive performance in the Ts65Dn mouse model of Down syndrome.

Individuals with Down syndrome (DS), a genetic condition due to triplication of Chromosome 21, are characterized by intellectual disability that worsens with age. Since impairment of neurogenesis and dendritic maturation are very likely key determinants of intellectual disability in DS, interventions targeted to these defects may translate into a behavioral benefit. While most of the neurogenesis enhancers tested so far in DS mouse models may pose some caveats due to possible side effects, substances naturally present in the human diet may be regarded as therapeutic tools with a high translational impact. Linoleic acid and oleic acid are major constituents of corn oil that positively affect neurogenesis and neuron maturation. Based on these premises, the goal of the current study was to establish whether treatment with corn oil improves hippocampal neurogenesis and hippocampus-dependent memory in the Ts65Dn model of DS. Four-month-old Ts65Dn and euploid mice were treated with saline or corn oil for 30 days. Evaluation of behavior at the end of treatment showed that Ts65Dn mice treated with corn oil underwent a large improvement in hippocampus-dependent learning and memory. Evaluation of neurogenesis and dendritogenesis showed that in treated Ts65Dn mice the number of new granule cells of the hippocampal dentate gyrus and their dendritic pattern became similar to those of euploid mice. In addition, treated Ts65Dn mice underwent an increase in body and brain weight. This study shows for the first time that fatty acids have a positive impact on the brain of the Ts65Dn mouse model of DS. These results suggest that a diet that is rich in fatty acids may exert beneficial effects on cognitive performance in individuals with DS without causing adverse effects.

Combined Treatment With Environmental Enrichment and (-)-Epigallocatechin-3-Gallate Ameliorates Learning Deficits and Hippocampal Alterations in a Mouse Model of Down Syndrome.

Intellectual disability in Down syndrome (DS) is accompanied by altered neuro-architecture, deficient synaptic plasticity, and excitation-inhibition imbalance in critical brain regions for learning and memory. Recently, we have demonstrated beneficial effects of a combined treatment with green tea extract containing (-)-epigallocatechin-3-gallate (EGCG) and cognitive stimulation in young adult DS individuals. Although we could reproduce the cognitive-enhancing effects in mouse models, the underlying mechanisms of these beneficial effects are unknown. Here, we explored the effects of a combined therapy with environmental enrichment (EE) and EGCG in the Ts65Dn mouse model of DS at young age. Our results show that combined EE-EGCG treatment improved corticohippocampal-dependent learning and memory. Cognitive improvements were accompanied by a rescue of cornu ammonis 1 (CA1) dendritic spine density and a normalization of the proportion of excitatory and inhibitory synaptic markers in CA1 and dentate gyrus.

Avaliação da modulação autonômica em indivíduos com síndrome de Down na equoterapia / Autonomic modulation of assessment in individuals with Down syndrome in hippotherapy

Introdução: A equoterapia é uma modalidade terapêutica que atende em grande parte os indivíduos com síndrome de Down, por apresentarem alterações motoras, cognitivas e sócio-afetivas. Sabe-se que as alterações na frequência cardíaca são moduladas pelo Sistema Nervoso Autônomo, entretanto, na literatura não há descrições sobre a Variabilidade de Frequência Cardíaca nestes praticantes, sobretudo na atividade relacionada à equoterapia. Objetivos: Avaliar a Variabilidade da Frequência Cardíaca de pacientes com Síndrome de Down antes, durante e após sessões de equoterapia. Métodos: Foram recrutadas 6 crianças com Síndrome de Down, idade média 12 ± 1,6 anos. A Frequência Cardíaca foi avaliada com um cardiofrequencímetro - Polar (RS800CX), antes, durante e após 5 sessões semanais. Resultados: Houve tendência a diminuição da atividade parassimpática no repouso inicial entre primeira e quinta sessão; e diminuição significativa da atividade parassimpática observada pelo índice pNN50 ao comparar a Frequência Cardíaca durante a primeira e quinta sessões. Conclusão: O tratamento equoterapêutico apresentou uma tendência à diminuição da Variabilidade da Frequência Cardíaca nas crianças estudadas.

Introduction: The hippotherapy is a therapeutic modality that serves largely individuals with Down syndrome, because they have motor, cognitive and socioemotional changes. It is known that changes in heart rate are modulated by the autonomic nervous system, however, in the literature there are no descriptions of the variability of heart rate in these practitioners, especially in the activity related to hippotherapy. Objectives: To evaluate Heart Rate Variability in practitioners of hippotherapy with Down Syndrome. Methods: Six children with Down Syndrome were recruited, age rate of 12 ± 1.6 years. The Heart Rate were evaluate using a cardiofrequencimetre ­ Polar (RS800CX), before, during and after 5 sessions of hippotherapy once weekly. Results: There were tendency of decrease in the parasympathetic activity during initial rest between first and fifth sessions, and significant decrease of the parasympathetic activity observed by the value of pNN50 compared to the Heart Rate during the first and fifth sessions. Conclusions: This study has shown that children treated with hippotherapy had tendency to have their Heart Rate Variability decreased.

Integrated care for Down syndrome.

Down syndrome (DS), caused by an extra copy of chromosome 21 (trisomy 21), is the most intensively studied human aneuploidy condition. It is the leading cause of intellectual disability and birth defects. Although most prenatally diagnosed DS fetuses are aborted in Taiwan, there are still some infants with DS who are diagnosed after birth. In addition to intellectual disability, people with DS face systemic problems that include short stature, dysmorphism, congenital heart disease, congenital anomalies of gastrointestinal and genitourinary tracts, abnormal endocrine function, leukemia and leukemoid reactions. To provide better care for people with DS in Taiwan, we began the DS multi-disciplinary clinic that has opened once per month since November 2013. The multi-disciplinary clinic consists of several subspecialists who provide care for DS people. To date, approximately 200 patients have used the clinic. The average number of patients who use the clinic per month is 27±6 with a mean patient age of 16±12 years old (range 0.3-53 years). The average number of patients per specialist on each clinic day is 5.2±4.9 (range 0.5-20.9 patients). We focus on early detection and prevention of medical and developmental issues associated with DS. This coordinated approach allows DS patients and family to have more comprehensive care.
