Influence of Cervical Spine Manipulation on Neck Joint Position Sense error in patients with chronic neck pain.
Authors: Miranda Iã Ferreira , Facchini Daniel , Manfio Eliane Fátima
Published: June 2017

Introduction: Cervical joint dysfunction may interfere with the sensorimotor afferent response, interfering with neck neck Joint Position Sense error (JPS). Objective: The aim of this study was to evaluate the influence of Cervical Spine Manipulation (CSM) on neck JPS error in patients with chronic neck pain. Method: 21 patients with chronic neck pain were divided into 2 groups: Spinal Manipulation Group (MG) or Sham Group (SG) who received 4 sessions of CSM and Sham CSM respectively. JPS was assessed in three different time frames: 1) pre-intervention; 2) Right after the first intervention (post-intervention 1); and 3) After a chronic intervention (post-intervention 2). The outcome measured in this study was the head reposition accuracy test with the Revel’s Test. Results: The JPS showed no significant differences between pre- and post-intervention 1 and 2 for any of the assessed groups. Conclusion: We conclude that, for this sample, neither the CSM nor the Sham CSM statistically changed the JPS error for neither groups. We believe that the changes in JPS after CSM were concealed because the ability of other sensory system information to compensate for inadequacies in any other component. Therefore, more studies have to be done with a stronger methodological rigor, clinical prediction rule for spinal manipulation, bigger sample and a blind assessment.
The irruption of time in the neurological space
Authors: Gagey Pierre-Marie
Published: June 2017

If I place an orthoses beneath a limited area of the plantar sole, I must accept the idea that this limited area of the plantar sole comes into contact with the ground before the neighboring areas. It is then possible to accept the hypothesis that this time lag between the ground contacts of the different zones of the foot sole introduces a temporal shift of the sensory messages emitted by the plantar sole. If this temporal shift of sensory messages does exist, which is not proven, then the placement of an orthoses beneath a limited area of the plantar sole alters the time series of events affecting the central nervous system. This modification may — must (?) — vary according to the height of the orthoses, which of course changes the time difference it causes.If I place an optical prism in front of an eye, I change around the direction of the visual space perceived by that eye. Whatever the mechanisms used by the central nervous system to compensate for the sensitive and sensory incoherencies produced by this displacement of the visual space, one is entitled to logically attribute them a temporal component since it is a displacement (sooner or later my foot touches the marks of this new visual space).It can be assumed that these changes in the temporal series of events affecting the central nervous system have no consequences for the individual, especially if these changes are minimal.Conversely, knowing the properties of non-linear dynamic systems, it can be assumed that changes in the temporal series of chained events affecting the central nervous system have consequences for the individual, especially if these changes are minimal [1].Until now, as far as we know, only a few researchers have tested this latter hypothesis, among human beings [2 - 6] or animals [7]. The conclusions of their works make it possible to propose this statement to criticism: « The regulation of the postural tonic activity of a subject can be modified by a minimal modification of his interface with the environment. »As this statement implies therapeutic potentialities, so long as it is not falsified it will represent a certain irruption of time in the neurological therapeutic thought, traditionally a little frileux and stuck within its spatial representations

Authors: Buldur Burak , Kapdan Arife
Published: June 2017

Purpose: The purpose of this study was to compare the antimicrobial efficacy of the EndoVac system and conventional needle irrigation to eliminate E faecalis in primary molar root canals. Study Design: 60 extracted human primary second molar roots were instrumented up to an apical size .04/35 and randomly divided into two groups; Group 1: conventional needle (n=30) and Group 2: EndoVac (n=30), and four subgroups (two experimental subgroups; (a) 2.5% sodium hypochlorite (NaOCl) + ethylenediaminetetraacetic acid (EDTA) (n=20), (b) ozonated water (OW) + EDTA (n=20), and control groups (c) 5.25% NaOCl (n=10) and (d) saline (n=10). All roots were sterilized and then inoculated with E.faecalis. Before and after final irrigation procedures, root canals were sampled and the grown colony forming units (CFUs) were counted. Data were analyzed by Kruskall-Wallis and Mann-Whitney U tests using a 0.05 significance level. Results: The EndoVac reduced more bacteria than the conventional needle did but it was not statistically significant (p>0.05). NaOCl alone or followed by EDTA totally eliminated bacteria. OW + EDTA showed higher reduction of bacteria but could not totally eliminate bacterias. Conclusions: In the context of bacterial elimination, the EndoVac was not significantly better than the conventional needle. Although, there were fewer CFU/mg when using EndoVac, there was not any statistically significant superiority to conventional needle irrigation. An OW+EDTA regimen showed antibacterial effect in the primary molar root canals but it was significantly less effective than NaOCl+EDTA.

Published: June 2017

Objective: To examine the effects of cola-flavored beverages and caffeine on growth and metabolism of Streptococcus mutans biofilm. This study was designed to determine if carbonated beverages or caffeine can increase S. mutans growth and biofilm formation and metabolic activity in vitro, potentially leading to increased S. mutans-associated cariogenicity in children that consume them. Study Design: Six different cola-flavored products, plus pure caffeine, and pure high fructose corn syrup (HFCS), at different concentrations similar to those in the beverages were tested. A 16-hour culture of S. mutans was treated with different dilutions in bacteriological media. To test for the effect on biofilm formation, the biofilm was stained with crystal violet. The absorbance was determined to evaluate biofilm growth. Biofilm metabolic activity was measured based on biofilm having the ability to reduce XTT to a water-soluble orange compound. Results: The inclusion of HFCS in the beverages, as well as pure HFCS, significantly enhanced bacterial biofilm formation and metabolic activity. Pure caffeine and the presence of caffeine in beverages did not significantly increase biofilm formation, but pure caffeine significantly increased metabolism, and Diet Coke had significantly greater metabolic activity than Caffeine-Free Diet Coke. Conclusions: HFCS increases both the biofilm formation and metabolism of S. mutans, and caffeine in some cases increases metabolism of S. mutans.

RESUMO:Este trabalho discute a aplicação da ferramenta tecnológica Webquest para ministrar os conteúdos de avaliação educacional e de avaliação aos alunos do curso de Pedagogia de uma instituição particular de ensino superior da cidade de Londrina-PR. A questão principal de investigação é: de que forma os graduandos concluintes do curso de Pedagogia percebem a utilização da Webquest em uma atividade didática? Essa questão é relevante porque, atualmente, além de tal recurso ser uma forma diferenciada de ferramenta tecnológica em sala de aula, o uso de Tecnologias de Informação e Comunicação tem possibilitado um impacto qualitativo no processo de ensino-aprendizagem. Para isso, foram utilizados os tipos de pesquisa descritiva bibliográfica, de campo e experimental. O ponto de partida são as concepções de Kenski (2003), Dodge (1996) e Ramos (2008), o planejamento, a intervenção pedagógica e a avaliação de uma atividade didática utilizando a Webquest. Os resultados indicam que a atividade contribui para a aprendizagem, motiva os alunos e permite que os graduandos se familiarizem e conheçam uma proposta de uso da tecnologia como contribuidora do processo de ensino-aprendizagem.  ABSTRACT:This work discusses the application of the technological tool Webquest to teach contents of educational evaluation and evaluation to the students of the Pedagogy course from a private institution of higher education of Londrina-PR.

Authors: Basso Rafaela , Silva Maria Helena Alves , Amaral Ivan Luiz Martins Franco
Published: June 2017

O Centro de Memória e Arquivo da FCM embora recente já tem um acervo histórico representativo da história da Faculdade, bem como da própria Unicamp. Entre os acervos presentes no CMA/FCM, estão os arquivos pessoais dos profissionais ligados à produção cientifica dessa Instituição, como docentes e pesquisadores. Tais conjuntos documentais permitem estudar suas contribuições no campo das Ciências da Saúde, suas trajetórias intelectuais e pessoais, e, por fim, permitem conhecer igualmente a história da própria Universidade Estadual de Campinas. Muitos documentos que fazem parte destes acervos são inéditos e não existem em nenhum outro centro documental da Universidade, informação esta muito importante neste ano de 2016, quando a Universidade comemora os seus 50 anos. Acervos como esses, portanto, são riquíssimos e, muitas vezes, podem ficar esquecidos nos laboratórios, nas salas espalhadas pelos corredores da Unidade e até mesmo nas casas de seus titulares, constituindo uma memória esquecida. O que se torna problemático quando estes indivíduos deixam de integrar os quadros acadêmicos da Faculdade, seja por razões de aposentadoria, afastamentos ou mesmo falecimento. Através da organização de eventos técnico-científicos, como workshops, encontros e palestras, o CMA busca evitar que situações como essas aconteçam, através da valorização da importância desses arquivos como repositórios da memória da Instituição e dos profissionais que dela fizeram parte. Além de divulgar a riqueza e diversidade da documentação preservada pelo CMA, a organização de tais eventos propõe mostrar as possibilidades de trabalhos com esses acervos, suas práticas de tratamento e organização , tendo em vista resgatar e preservar a memória institucional, mobilizando os servidores docentes e não docentes sobre a importância que os documentos preservados em uma instituição como a Faculdade de Ciências Médicas possuem para além da celebração da memória de seus titulares.
Análise da rugosidade em furos obtidos por fresamento helicoidal interpolado e broca com insertos intercambiáveis
Authors: Magri Aristides , Diniz Anselmo Eduardo , Suyama Daniel Iwao , Correa Fabiano
Published: June 2017

Furos são elementos muito comuns e importantes “features” em peças mecânicas. Empregados em várias peças e produtos que desempenham importantes funções como: condutores de fluídos, alojamento de rolamentos, interiores de roscas, acoplamento de eixos, buchas, fixação etc. Os furos podem ser realizados por diferentes processos, cada um com suas características e importâncias dentro da manufatura.Na furação convencional com brocas, a qualidade do furo não é atingida e uma operação posterior se faz necessária. Uma alternativa para elevar a qualidade dos furos é o uso do fresamento helicoidal interpolado (FHI). O presente trabalho tem por objetivo principal avaliar e comparar as qualidades dos furos obtidos por brocas com insertos intercambiáveis e o fresamento helicoidal interpolado. Nos ensaios o material do corpo de prova utilizado foi o aço ABNT 1045 e 2 parâmetros de corte em níveis diferentes: avanço (f), 1 e 2 mm/ciclo além de 0,08 e 0,15 mm/dente para o fresamento e na furação 0,047; 0,100 e 0,150 mm/volta, em segundo a velocidade de corte (vc) 350 e 385 m/min para o fresamento e 120 e 180 m/min para a furação. Os parâmetros de saída analisados foram a rugosidade superficial e tempo de furação dos processos utilizados. Foi constatado que a rugosidade superficial está diretamente relacionada com o tempo de usinagem, uma vez que este é influenciado diretamente pelo avanço axial (faz) o qual possui a maior influência na rugosidade.
A utilização de óleos emulsionáveis em máquinas ferramenta de usinagem
Authors: Magri Aristides , Gatamorta Fábio , Suyama Daniel Iwao , Hassui Amauri
Published: June 2017

A usinagem é um dos processos de fabricação no qual forma e dimensões são obtidas por meio de remoção de partículas de material. Nessa remoção, há geração de calor que é prejudicial à peça a ser gerada, à ferramenta, ao operador e ao ambiente de trabalho. O aquecimento excessivo deforma a peça e produz imperfeições no trabalho, em consequência do arranchamento de partículas metálicas das camadas abaixo do corte. Posteriormente, pelo calor, estas se soldam á parte cortada. Além disso, o superaquecimento reduz a vida útil da ferramenta, exigindo frequentes afiações. A quantidade de calor depende da velocidade do corte, da dureza do metal e do tipo das operações. Como o próprio nome diz, os fluidos de corte são fluidos com ação lubrificante e refrigerante e são utilizados para que seja evitada ou minimizada esta geração de calor. Possuem composições complexas que variam de acordo com o tipo de operação executada e com os materiais a serem trabalhados. Em sua grande maioria, levam óleos vegetais ou minerais que fazem com que o descarte deva obedecer a uma legislação e não seja uma ação trivial. Este trabalho apresenta algumas maneiras de descartar ou armazenar o óleo, evitando o manuseio errado que poderia causar sérios danos ao meio ambiente.
História oral e a arte de (re)memorar: experiencia junto aos alunos da universidade terceira idade da UNICAMP
Authors: Souza Carlos Roberto Pereira
Published: June 2017

Trata-se a experiencia conjunta com alunos da UniversIdade (Universidade da Terceira Idade) da UNICAMP, que ocorreu no segundo semestre de 2016. A Oficina proporcionou aos estudantes “uma verdadeira viagem à memória”, pois contamos com as técnicas da Metodologia da História Oral , abordagem qualitativa, por sua vez, trata-se de uma poderosa ferramenta na reconstrução da memória e do passado presente. A História Oral tem um papel principal no processo de reconstrução das memórias subterrâneas ou subjulgadas, ou seja, daquelas ações não registradas por outro tipo de documentação, o que torna esse registro oral um suporte complementar na compreensão do presente. Delgado (2006, p. 16) afirma que: A memória, principal fonte de depoimentos orais, é um cabedal infinito, onde múltiplas variáveis – temporais, topográficas, individuais, coletivas – dialogam entre si, muitas vezes revelando lembranças, algumas vezes, de forma explícita, outras vezes de forma velada, chegando em alguns casos a ocultá-las pela camada protetora que o próprio ser humano cria ao supor, inconsciente, que assim está se protegendo das dores, dos traumas e das emoções que marcam sua vida. Outro ponto positivo, que vale ressaltar, que ao final do curso, os aluno (a)s estavam motivados e capacitados a reconstruírem suas estórias de vidas ; suas memórias familiares, dos seus bairros; das comunidades onde frequentam ou estão inseridos.

Published: June 2017

The main objective of the present study was to investigate arsenate [As (V)] resistance genes in rice cultivars grown in arsenic contaminated Egyptian soil in order to genetically induce resistance against arsenic in the local rice varieties as well as defining contaminated rice grains and/or soil. Three local rice cultivars; Sakha 102-104 were cultivated on modified Murashige and Skoog Basal Medium (MS medium) containing elevated concentrations of arsenate (0.1, 1 and 10 mg/l). The three varieties showed different resistant attitudes against arsenate with Sakha 104 being the most resistant. Extracted messenger RNA (mRNA) from treated and untreated Sakha 104 plantlets was scanned using differential display to demonstrate the arsenate resistant genes using three different arbitrary primers. About 100 different RNAs with (1500 bp - 50 bp) were obtained from which seven were up-regulated genes, subjected to DNA cloning using TOPO TA system and the selected clones were sequenced. The sequence analysis described four genes out of the seven namely disease resistance protein RPM1, Epstein-Barr virus EBNA-1-like, CwfJ family protein and outer membrane lipoprotein OmlA while the other three genes were hypothetical proteins. It is concluded the four induced genes in the resistant rice cultivar considered as a direct response to arsenic soil pollution. Genes detected in the present study can be used as geno-sensors for rice grains and soil contamination with As (V). Moreover, local rice cultivars may be genetically modified with such genes to induce high resistance and to overcome arsenic soil pollution.
Inorganic Anion Regulates the Phase Transition in Two Organic Cation Salts Containing [(4-Nitroanilinium)(18-crown-6)]+ Supramolecules

Published: June 2017

Two novel inorganic–organic hybrid supramolecular assemblies, namely, (4-HNA)(18-crown-6)(HSO4) (1) and (4-HNA)2(18-crown-6)2(PF6)2(CH3OH) (2) (4-HNA = 4-nitroanilinium), were synthesized and characterized by infrared spectroscopy, single X-ray diffraction, differential scanning calorimetry (DSC), and temperature-dependent dielectric measurements. The two compounds underwent reversible phase transitions at about 255 K and 265 K, respectively. These phase transitions were revealed and confirmed by the thermal anomalies in DSC measurements and abrupt dielectric anomalies during heating. The phase transition may have originated from the [(4-HNA)(18-crown-6)]+ supramolecular cation. The inorganic anions tuned the crystal packings and thus influenced the phase-transition points and types. The variable-temperature X-ray diffraction data for crystal 1 revealed the occurrence of a phase transition in the high-temperature phase with the space group of P21/c and in the low-temperature phase with the space group of P21/n. Crystal 2 exhibited the same space group P21/c at different temperatures. The results indicated that crystals 1 and 2 both underwent an iso-structural phase transition.

Performance of Multiphase Twin-Screw Pump During the Period of Wet-Gas Compression
Authors: Patil Abhay , Morrison Gerald
Published: June 2017

Sealflush recirculation in twin-screw pumps is an important function because it serves the purpose of not only cooling the seal faces but also sealing the gas leakage from one cavity to another during the period of wet gas compression, which directly affects the pump performance. This study focuses on evaluating the effect of heat generation during the period of wet gas compression on the pump performance and potential mitigation measures to consequential issues for fixed flow rate of sealflush-fluid recirculation. A new design of twin-screw pump skid with an inbuilt closed-loop sealflush-circulation loop was tested for 150-, 200-, and 250-psi pressure differentials at 10-psi suction pressure. A sealflush flow of approximately 6% was maintained at an operating speed of 3,600 rev/min with 100% gas at the pump inlet. Pump performance was observed as the temperature rose from approximately 95°F to 180°F. Heat generation caused by gas compression significantly reduced the pump volumetric efficiency. Pump performance was characterized as a function of exhaust temperature for given pressure differentials. Effect of sealflush-fluid viscosity was investigated. Volumetric efficiency was found to decrease slightly with an increase in sealflush-fluid viscosity. Sealflush fluid was quenched to evaluate the effect of cooling. Cooling the sealflush fluid significantly affected the pump performance, reinstating the efficiency to near its optimal value.
Study of the Transient Terrain–Induced and Severe Slugging Problems by Use of the Drift–Flux Model
Authors: Spesivtsev P. E. , Kharlashkin A. D. , Sinkov K. F.
Published: June 2017

The drift-flux model is applied to simulate numerically highly transient slug flows in complex configurations. The study is focused on the terrain-induced slugging phenomenon. Previously published transient experimental data on multiphase flows in complex configurations with near-horizontal segments are closely investigated. The numerical implementation of the drift-flux model is briefly described. By varying the specific tuning parameters of the drift velocity, a close match with the transient experimental data for air/water flows is obtained. To verify the quality of the numerical solution and agreement with experimental data, the problem-specific criteria are introduced. These criteria are the time of the first slug arrival, average amplitude of slugs, average period between the slugs, average cumulative liquid production per slug, and total produced mass over the observation period. The model developed was used to predict severe slugging for the synthetic case involving the flow of hydrocarbon oil and gas and is representative of the realistic field-scale problem. The possible ways of further improving the drift-flux model and its potential practical applications are outlined.

Due to the ever present problem of excessive eutrophication of both surface waters and their main receiver, i.e. Baltic Sea, it becomes important to determine not only the concentration of nutrients in selected river profiles, but also an attempt to answer the question of which of the elements is a factor limiting the growth of biomass. Biological production in surface area is dependent on a number of factors including the relations between the nitrogen and phosphorus during photosynthesis. The study, whose results were presented in the article, was conducted in 2012–2014 on two littoral river basins, Rega and Słupia, in three cycles throughout the year including both vegetation period, the period after the removal of crops from the fields and the period of early spring, immediately after the thaw snow. On the basis of the results were analyzed variability of daily and seasonal concentrations of biogenic compounds and on the basis determined which of the elements limits the increase in biomass in selected catchments using the dependence that exists between the nitrogen and phosphorus in surface waters called Redfield ratio.

The analysis includes 3 technologies - 2 traditional variants, used ceramic materials and timber frame and 1 innovative solution based on the expanded polystyrene. These solutions were assessed according to 12 factors, characterizing the most important areas of sustainable development. We observed no clear advantage of one of the analyzed construction-material solutions over the remaining in terms of these factors, what was the starting point for the multi-criteria analysis. A solutions comparison was made using WAP, AHP and TOPSIS methods and technology that best meets the analysis assumptions, was searched. As a result of the study, it was found the dominance of solution using timber frame, three times confirmed (in each method multi-criteria analysis). The results make it possible to compare the technologies, indirectly-indicate building materials, which meet the assumptions of sustainable development and determine degree of implementation of sustainable development in emerging technologies.

The article presents the results of research illustrating the use of environmental requirements in the description of the subject-matter of contract for the construction of wastewater infrastructure which took place in 2009-2015. Public contracting rarely apply environmental clauses into tender documentation (Korytárová i inni, 2015). The percentage of their use is so small that in the context of the sample, it is difficult to talk about the implementation of sustainable development policies.

A paper focuses on analyzing the impact of Big Data (BD) on minimizing the risk in investment and construction projects. The work presents the aspects of risk occurring during the execution of the construction project. It presents an on-line survey which was aimed at knowing the opinion of Polish construction companies on the BD, and checking their readiness to implement technologies supporting manipulation of the data. It was underlined that results of the BD analysis provide a powerful tool for risk management, however, it is hardly noticed by the Polish respondents.

Authors: Canale Rosaria , Liotti Giorgio

The institutional and policy features of Eurozone represent a field of special interest to analyse the process of integration. The aim of this study is to investigate on the existence of a trade-off between the compliance to fiscal rules and trust as a proxy of institutional legitimacy in Eurozone. At this scope, the relation between trust in the European Central Bank (ECB) and structural adjustment, together with unemployment and inflation in 11 Eurozone countries from 1999 to 2013, is tested. The empirical results showed that: (i) discretionary policy measures have an opposite sign impact on trust; (ii) in peripheral countries, the structural adjustment is the main variable affecting trust in ECB; (iii) unemployment plays a key role; and (iv) deviation from the objective of 2% of inflation is not significant. These outcomes prove the existence of a trade-off between the fiscal rules commitments and the European institutional consolidation process.
A teoria da linguagem de Dewey e o contexto cultural da investigação humana
Authors: Cabral Caio César
Published: June 2017

Neste artigo discutimos como se produz, mais uma vez no contexto da teoria da investigação de Dewey, a transformação das interações puramente orgânicas entre homem e ambiente em interações inteligentes, vale dizer, em pesquisa humana capaz de solucionar problemas. Exporemos, mais precisamente, as bases culturais da teoria da investigação do filósofo, acompanhando passo a passo a análise que ele faz da linguagem e dos símbolos linguísticos.
Sobre a viabilidade computacional de uma arquitetura cognitiva não-modular
Authors: Meurer César Fernando
Published: June 2017

A escola fodoriana e a psicologia evolucionária são frequentemente apresentadas como perspectivas rivais no interior da tradição computacionalista. Não obstante, elas concordam em um ponto fundamental: uma arquitetura cognitiva não-modular é computacionalmente inviável. A interpretação oferecida neste artigo mostra que Fodor, ao apostar suas fichas em uma noção estrita de módulo (módulos são informacionalmente encapsulados), termina rejeitando o computacionalismo em nome da confiança na existência de um sistema central. A psicologia evolucionária, por sua vez, aposta em uma noção menos estrita de módulo (módulos podem receber inputs uns dos outros), o que leva ao resultado inverso: rejeição da ideia de sistema central em nome da confiança no computacionalismo.

OBJECTIVE To determine the pharmacokinetics and adverse effects following SC administration of ceftiofur crystalline free acid (CCFA) in New Zealand White rabbits.

ANIMALS 6 adult sexually intact female New Zealand White rabbits.

PROCEDURES Each rabbit was administered 40 mg of CCFA/kg SC. A blood sample was obtained immediately before (0 minutes), at 5 and 30 minutes after, and at 1, 1.5, 2, 3, 4, 8, 12, 24, 48, 72, 95, 120, 144, and 168 hours after administration, and plasma concentrations of ceftiofur free acid equivalents (CFAE) were measured. Pharmacokinetic parameters were calculated. For each rabbit, body weight, food consumption, fecal output, and injection site were monitored. Minimum inhibitory concentrations of ceftiofur for 293 bacterial isolates from rabbit clinical samples were determined.

RESULTS Mean ± SD peak plasma concentration of CFAE and time to maximum plasma concentration were 33.13 ± 10.15 μg/mL and 1.75 ± 0.42 hours, respectively. The mean terminal half-life of CFAE was 42.6 ± 5.2 hours. Plasma CFAE concentration was > 4 μg/mL for approximately 24 hours and > 1 μg/mL for at least 72 hours after CCFA administration. An apparently nonpainful subcutaneous nodule developed at the injection site in 3 of 6 rabbits.

CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that CCFA (40 mg/kg) could be administered SC every 24 to 72 hours to New Zealand White rabbits to treat infections with ceftiofur-susceptible bacteria. Single-dose administration of CCFA resulted in minimal adverse effects. Additional studies are needed to evaluate the effects of repeated CCFA administration in New Zealand White rabbits.

Introdução: Grande parte das quedas em idosos ocorre ao andar e realizar ações secundárias, pois a dupla tarefa aumenta a demanda atencional e motora necessárias para controle e manutenção do equilíbrio. Objetivo: avaliar os efeitos de um protocolo cinesioterapêutico de dupla tarefa sob o risco de quedas relacionada à mobilidade e o equilíbrio corporal dinâmico e à demanda atencional em idosos. Materiais e métodos: Estudo de intervenção com 40 idosas ingressantes de um programa assistencial ao idoso, submetidos a um protocolo cinesioterapêutico de dupla tarefa envolvendo simultaneamente tarefas motoras e cognitivas por 16 semanas, com duas sessões semanais de 50 minutos. Na coleta de dados, empregou-se o teste Timed Up and Go (TUG Simples) para avaliar o risco de queda e o Timed Up and Go cognitivo (TUG Cognitivo) para avaliar a demanda atencional relacionada ao risco de quedas. Para a análise estatística, utilizou-se o programa SPSS 18.0. Na estatística descritiva, as variáveis foram apresentadas em média, frequência relativa e percentual. Para a análise do efeito do protocolo sobre a capacidade atencional e risco de cair, utilizou-se o teste de Wilcoxon, sendo considerado significativo p<0, 05.Resultados: Quanto ao risco de queda, o tempo médio de execução antes da intervenção foi 23,09 segundos e depois do protocolo,19,73 segundos (p<0,0001). 40 (100%) dos idosos estudados, apresentavam risco moderado de queda antes da intervenção e após o protocolo, 36 idosos (90%), apresentaram baixo risco de queda.  Quanto à capacidade atencional relacionada ao risco de queda, o tempo médio de execução dos testes antes da intervenção foi de 26,87 segundos e depois da intervenção foi de 19,80 segundos (p<0,0001). Antes da aplicação do protocolo, 39 idosos (97,50%) apresentavam alto risco de quedas e após a intervenção, 34 idosos (85%) apresentaram baixo risco de queda. Conclusão: o protocolo de dupla tarefa utilizado diminuiu o risco de queda nos idosos estudados, tanto relacionado ao aspecto da mobilidade funcional isolada, quanto associada ao aspecto cognitivo. Sugere-se, assim, o a adição de exercícios de dupla tarefa na prática clínica e nas práticas de atividades físicas. Palavras-chave: Quedas,Dupla Tarefa,Idosos.
