ABSTRACT

O objetivo do estudo foi verificar a influência do estímulo visual e posicionamento dos membros superiores no controle postural ortostático e avaliar o efeito do sexo e idade nas respostas posturais de crianças e adolescentes. Estudo transversal, com amostra de 84 participantes com idade entre 11 e 14 anos, ambos os sexos (55 meninas), de escola pública de Goiânia (GO). Além do exame físico, o controle postural foi avaliado na posição ortostática pela baropodometria computadorizada em três condições: olhos abertos, olhos fechados e olhos abertos com ombros a 90° de abdução. A ausência do estímulo visual gerou maior instabilidade postural em comparação à condição de olhos abertos. Em relação as diferenças existentes entre os sexos, foi observado que as meninas tiveram menores valores de deslocamento anteroposterior e área da elipse que os meninos. Comparando-se os olhos abertos e fechados, as meninas apresentaram maiores valores na área da elipse e os meninos nos deslocamentos anteroposterior e látero-lateral. Ao analisar o efeito da idade foi observado que o grupo com 13 e 14 anos apresentou maiores valores em todas as variáveis analisadas. A ausência do estímulo visual aumentou os valores da área da elipse no grupo com 11 e 12 e dos deslocamentos no grupo com 13 e 14 anos. Não foi verificado efeito interativo entre sexo e idade. Na condição de abdução dos membros superiores não houve diferença no controle postural. Conclui-se que a ausência do estímulo visual foi mais impactante na manutenção do controle postural ortostático em crianças e adolescentes em relação as outras condições avaliadas, existindo diferença entre os sexos e a idade, em que os meninos e o grupo com 13 e 14 anos realizaram mais ajustes para manter o controle postural.

The aim of this study was to verify the influence of visual stimulus and positioning of the upper limbs in the orthostatic postural control, and to assess the effects of gender and age in the postural responses of children and adolescents. This was a transversal study involving 84 participants (of which 55 were girls) from public schools in Goiania (GO - Brazil) with age between 11 and 14 years. Besides physical examination, the participants' postural control was assessed in the orthostatic position by computerized baropodometry in three different conditions: eyes-open, eyes-closed, and eyes-open with shoulders at 90º abduction. The absence of visual stimulus generated more postural instability in relation to the eyes-open condition. Regarding gender differences, the girls had lower anteroposterior and ellipse area displacement than boys. Comparing the eyes-open and eyes-closed conditions, the girls presented higher values in the ellipse area and the boys presented higher values in the anteroposterior and laterolateral displacements. Analyzing the effect of age, the participants between 13 and 14 years old presented higher values in all variables. The absence of visual stimulus increased the values of the ellipse area in the participants between 11 and 12 years of age and the values of displacements in the participants between 13 and 14 years of age. Interactive effect between genders and age has not been verified. There were no postural control differences in the upper limbs abduction condition. Conclusion: The absence of visual stimulus was more impacting in the support of orthostatic postural control in children and adolescents than the other conditions assessed; the boys and the participants between 13 and 14 years of age made more adjustments in order to maintain postural control.

ABSTRACT

As dores lombares podem causar frequentes incapacidades a longo prazo. O tratamento inicial de problemas lombares é realizado através de medicamentos e de fisioterapia; mas a cirurgia de artrodese também pode ser considerada para alguns casos específicos. Entretanto, acredita-se que a artrodese lombar pode afetar negativamente a marcha. O principal objetivo deste estudo foi identificar possíveis alterações nos parâmetros cinemáticos da marcha de indivíduos submetidos a artrodese lombar. Fizeram parte da amostra quinze indivíduos com médias de idade de 55,40 anos, de peso de 79,84 quilogramas, de altura de 1,60 metros e de tempo de pós operat ório de 59,33 meses. Um sistema de cinemetria capturou a trajetória tridimensional da marcha. Para a avaliação funcional, o questionário de Roland Morris (RMDQ) foi utilizado. O teste t para uma amostra foi utilizado para comparar com as variáveis da marcha com a normalidade; e o teste de correlação de Spearman, para verificar as correlações entre os parâmetros da marcha e o RMDQ, tempo de procedimento cirúrgico e idade. Os valores de velocidade (p < 0,0001), do comprimento da passada (p < 0,0001) e da largura do passo (p < 0,0001) apresentaram-se inferiores quando comparado aos valores normativos. Os resultados do questionário de RMDQ demonstraram que os participantes apresentaram níveis baixos de funcionalidade; com uma correlação forte e estatisticamente significativa (p < 0,05) entre a funcionalidade e a velocidade, cadência, tempo da passada e largura do passo. Resultados similares também foram encontrados em pacientes em tratamento conservador, demonstrando a falta de eficiência desse procedimento cirúrgico. Por isso, de ve-se questionar as reais necessidades da artrodese lombar, avaliando a gravidade e os objetivos de cada paciente com o intuito esgotar ao máximo as po ssibilidades de tratamento conservador antes da opção pela artrodese lombar.

Low back pain can cause frequent long-term disabilities. The initial treatment for low back problems is medication and physiotherapy; but arthrodesis surgery can also be considered for some specific cases. However, it is believed that lumbar arthrodesis can negatively affects gait. The main objective of this study was to identify possible changes in gait kinematic parameters after lumbar arthrodesis. Sample was composed by fifteen individuals with a mean age of 55.40 years, weighing 79.84 kilograms, height of 1.60 meters and postoperative time of 59.33 months. A kinematic system captured the three -dimensional trajectory of the gait. For functionality evaluation, the Roland-Morris Disability Questionnaire (RMDQ) was used. The t-test for one sample was used to compare gait variables with normality; and the Spearman correlation test was used to verify the correlations between gait par ameters and RMDQ, surgical time and age. The values of velocity (p < 0.0001), stride length (p < 0.0001) and step width (p < 0.0001) were lower when compared to normative values. The results of the RMDQ showed that participants had low levels of functionality; with a strong and statistically significant correlation (p < 0.05) between functionality and velocity, between functionality and cadence, between functionality and stride time, and between functionality and stride widt h. Similar results were also found in patients under conservative treatment, demonstrating this surgical procedure is inefficiency. Therefore, should be asked the real needed for lumbar arthrodesis, measuring the severity and objectives of each patient in order to fully exhaust the possibilities of conservative treatment b efore opting for lumbar arthrodesis.

ABSTRACT

O presente trabalho trata-se de um estudo realizado com 17 crianças com faixa etária entre 4 e 5 anos, todas matriculadas no Centro de Educação Infantil ­ campus da Universidade Estadual de Londrina (CEI-UEL), tendo como objetivo avaliar o desempenho motor dessas crianças através do TGMD-3, antes e após uma intervenção motora, realizada no CEI-UEL. A intervenção foi composta de 29 sessões de 60 minutos em que eram trabalhadas diferentes habilidades motoras, após a qual foi aplicado novamente o TGMD-3 para avaliar se a intervenção havia influenciado positivamente o desempenho das crianças da amostra. Nossos resultados mostraram que para a variável somatória das habilidades de locomoção e habilidades com bola foi apresentado um aumento na comparação do pré-teste para o pós-teste, porém somente nas habilidades de locomoção foi encontrada significância na melhora. Quanto ao percentil, nas habilidades com bola foi encontrado um desempenho inferior no pós-teste, mas sem que houvesse diferença significativa entre os resultados; já para as habilidades de locomoção foi encontrada uma melhora no pós-teste do percentil, mas sem diferença significativa em comparação ao pré-teste. Com relação ao escore não foi encontrada diferença significativa para as habilidades, porém nas habilidades de locomoção houve desempenho superior no pós-teste e nas habilidades com bola houve desempenho inferior. Como conclusão, podemos inferir que a intervenção motora foi positiva para a melhora do desempenho das crianças, mas não para todas as variáveis analisadas, demonstrando que a intervenção motora pode ser uma ferramenta benéfica para o desempenho motor de crianças.


The present work is a study carried out with 17 children aged between 4 and 5 years old, all enrolled at the Child Education Center - campus of Universidade Estadual de Londrina (CEI-UEL), with objective of evaluating children motor performance through the TGMD-3, before and after a motor intervention, performed at CEI-UEL. The intervention consisted of 29 60-minute sessions with different motor skills, and after the 29 sessions, TGMD-3 was applied again to assess whether the intervention had positively influenced the performance of the children in the sample. Our results showed that for the sum of the walking and ball skills showed an increase in the comparison of the pre-test to the post-test, but only in the walking skills the difference was significant. As for the percentile, in the skills with the ball a lower performance was found in the post-test, but without any significant difference between the results; for the locomotion skills, an improvement was found in the post-test according to the percentile, not showing a significant difference compared to pretest. Regarding the score, no significant difference was found for the skills, but in the locomotion skills there was a superior performance in the post-test and in the skills with ball there was a lower performance. As a conclusion, we can deduce that motor intervention was positive for improving children motor performance, but not for all variables, showing that the motor intervention could be a beneficial tool to children motor performance.

ABSTRACT

Background: The unprecedented increase in metal exposure has been aided by modern industrialization and anthropogenic activities. Cadmium and mercury are recognized as two of the most common heavy metals with destructive impacts on most organ systems. The present study was designed to investigate and improve existing literature on the possible deleterious effects of cadmium and mercury exposure. Methods: Adult Wistar rats were treated with cadmium chloride (5 mg/kg/day) and mercury chloride (4 mg/kg/day) for 14 days. Body, brain and cerebellar weights, motor deficits, antioxidant and lipid peroxidation activities as well as histological alterations to the cerebellum were evaluated at the end of the experiment. Results: Findings showed a significant reduction in body and brain weights, dysregulation of antioxidant enzymes activity and impaired locomotion and exploratory activity in treated rats. Also, an increase in lipid peroxidation and degeneration of Purkinje cells of the cerebellum was observed in treated rats. Conclusion: Overall, these results corroborate previous findings that cadmium and mercury induce deleterious effects on the cerebellum and central nervous system. In addition, this study helps to provide an anatomical perspective and information on the exact cerebellar changes induced by cadmium and mercury in Wistar rats.

ABSTRACT

Vestibular compensation is an important model for developing the prevention and intervention strategies of vestibular disorders, and investigating the plasticity of the adult central nervous system induced by peripheral injury. Medial vestibular nucleus (MVN) in brainstem is critical center for vestibular compensation. Its neuronal excitability and sensitivity have been implicated in normal function of vestibular system. Previous studies mainly focused on the changes in neuronal excitability of the MVN in lesional side of the rat model of vestibular compensation following the unilateral labyrinthectomy (UL). However, the plasticity of sensitivity of bilateral MVN neurons dynamically responding to input stimuli is still largely unknown. In the present study, by using qPCR, whole-cell patch clamp recording in acute brain slices and behavioral techniques, we observed that 6 h after UL, rats showed a significant deficit in spontaneous locomotion, and a decrease in excitability of type B neurons in the ipsilesional rather than contralesional MVN. By contrast, type B neurons in the contralesional rather than ipsilesional MVN exhibited an increase in response sensitivity to the ramp and step input current stimuli. One week after UL, both the neuronal excitability of the ipsilesional MVN and the neuronal sensitivity of the contralesional MVN recovered to the baseline, accompanied by a compensation of spontaneous locomotion. In addition, the data showed that the small conductance Ca2+-activated K+ (SK) channel involved in the regulation of type B MVN neuronal sensitivity, showed a selective decrease in expression in the contralesional MVN 6 h after UL, and returned to normal level 1 week later. Pharmacological blockage of SK channel in contralateral MVN to inhibit the UL-induced functional plasticity of SK channel significantly delayed the compensation of vestibular motor dysfunction. These results suggest that the changes in plasticity of the ipsilesional MVN neuronal excitability, together with changes in the contralesional MVN neuronal sensitivity, may both contribute to the development of vestibular symptoms as well as vestibular compensation, and SK channel may be an essential ionic mechanism responsible for the dynamic changes of MVN neuronal sensitivity during vestibular compensation.

ABSTRACT

OBJECTIVE@#To explore whether the characteristic responses to sound stimulations of the auditory neurons in the striatum is regulated in different behavioral states.@*METHODS@#The auditory neurons in the striatum of awake C57BL/6J mice were selected for this study. We recorded the auditory response of the striatum to noises over a long period of time by building a synchronous in vivo electrophysiological and locomotion recording system and using glass microelectrode attachment recording. By analyzing the running speed of the mice, the behavioral states of the mice were divided into the quiet state and the active state, and the spontaneous activity and evoked responses of the auditory neurons in the striatum were analyzed in these two states.@*RESULTS@#Compared with those recorded in the quiet state, the spontaneous activity of the auditory neurons in the striatum of the mice increased significantly (37.06±12.02 vs 18.51±10.91, P < 0.001) while the auditory response of the neurons decreased significantly (noise intensity=60 dB, 3.45±2.99 vs 3.04±2.76, P < 0.001) in the active state.@*CONCLUSION@#Locomotion has a significant inhibitory effect on the auditory response of the striatum, which may importantly contribute to the decline of sound information recognition ability in the active state.

ABSTRACT

En el presente trabajo se incorpora al estudio de la movilidad cotidiana desde el reconocimiento de experiencias de las personas con discapacidad y la relación con el espacio urbano. El debate sobre la movilidad cotidiana en la ciudad desprende varios frentes de análisis, refiere a una solicitud coyuntural de dinámicas urbanas en correspondencia con los actores sociales; así mismo, propone una observación multidisciplinaria desde enfoques teóricos-metodológicos para la argumentación de la realidad social contemporánea. La propuesta es una delimitación sobre enfoques que ofrece la panorámica sobre el fenómeno de la movilidad y las implicaciones de nuevas categorías, así como la incorporación de otros actores que se deben contemplar para establecer un proceso de inclusión y accesibilidad. Se suscribe en un esquema desde las prácticas de la movilidad con relación a una escala a nivel micro (tanto en lo espacial como lo social) que favorece la detección de diferenciaciones en el mismo entorno bajo características particulares. La dinámica de la movilidad cotidiana refleja diversas problemáticas urbanas que precisan abordarse no sólo en términos de cantidad sino de calidad. Tales dificultades dentro del entorno urbano implican cuestiones como el tiempo, contemplado desde la espera del transporte, el traslado, el trasbordo y las eventualidades que llegasen a ocurrir; así como la distancia, los trayectos entre los centros laborales o educativos y las zonas residenciales. Todas estas contradicciones dentro de la vida cotidiana presentan otro matiz para los individuos de características diferentes, para personas con discapacidad, adultos mayores, menores de edad que comparten en el espacio como transeúntes de la ciudad.


This paper is incorporated to everyday mobility studies from recognizing experiences of people with disabilities in relation to the urban space. The debate on everyday mobility in the city allows different ways to be analyzed; it refers to a relevant request about urban dynamics linked to social actors. Likewise it is a proposal to observe through a multidisciplinary approach and focus on theory and methodology to discuss about current social reality. The proposal is a boundary among approaches which offers a perspective about the phenomenon of mobility and new categories and the incorporation of other actors that must be considered to establish a process of inclusion and accessibility. It is an outline from mobility practices in relation to micro scale from special to social aspects that allows detecting distinctions in the same surroundings under individual characteristics.

ABSTRACT

INTRODUCTION: Down syndrome individuals have different gait patterns, which include specific characteristics such as foot rotation asymmetryOBJECTIVE: The aim of this study was to analyze the relationship between this asymmetry and the hands-and-knees crawling pattern before gait acquisition in Down syndrome children, as well as the possible association of this gait to gender, ethnicity, comorbidities, physiotherapy, and occupational therapy interventionsMETHODS: In this cross-sectional study, 361 children with or without foot rotation asymmetry were selected. An online questionnaire was administered to the parents or guardians of those childrenRESULTS: Hands-and-knees crawling decreased the prevalence of foot rotation asymmetry in Down syndrome children. The longer it took for walking onset, the higher the prevalence of this asymmetry. Indeed, for each month of delay, there was a 7% increase in prevalence. There was a significant relationship between orthopedic alterations in knees or flat feet and foot rotation asymmetry. There was no significance related to gender, ethnicity, other comorbidities, physiotherapy, or occupational therapy interventionsCONCLUSION: The findings in this study revealed that foot rotation asymmetry might be related to the acquisition of motor skills, hands-and-knees crawling and the walking onset


INTRODUÇÃO: As pessoas com síndrome de Down (SD) apresentam diferentes padrões de marcha, incluindo algumas características específicas como a marcha de base alargadaOBJETIVO: O objetivo deste estudo foi analisar a relação entre a marcha de base alargada e a aquisição motora engatinhar em quatro apoios adquiridas antes da marcha em crianças com SD, bem como a provável associação desta marcha com gênero, etnia, comorbidades e tratamentos de fisioterapia e terapia ocupacionalMÉTODO: Neste estudo transversal, foram selecionados 361 indivíduos que apresentaram ou não marcha de base alargada. Um questionário on-line foi administrado para pais / responsáveis destas criançasRESULTADOS: O engatinhar em quatro apoios diminuiu a prevalência da marcha de base alargada em crianças com SD. Quanto maior o tempo em meses para os primeiros-passos, maior a prevalência de base alargada, sendo que, a cada mês de atraso, a prevalência aumenta em 7%. Foi observada significância entre as alterações ortopédicas em joelhos e pés planos e a marcha de base alargada. Não foi encontrada significância relacionada a gênero, etnia, outras comorbidades, fisioterapia ou terapia ocupacionalCONCLUSÃO: Os achados deste estudo mostraram que o aparecimento da base alargada pode estar relacionado às aquisições motoras, engatinhar em quatro apoios, e aos primeiros passos

ABSTRACT

RESUMEN La enfermedad podal constituye uno de los síndromes más difíciles de controlar en la industria lechera. El presente estudio tuvo como objetivo cuantificar la prevalencia de enfermedad podal, evaluando su asociación con factores como raza, orden de parto y peso. Se trata de un estudio retrospectivo que utiliza los registros sanitarios y productivos de un hato lechero ubicado en el trópico alto de Colombia. Los componentes raciales presentes fueron Fl Holstein x Blanco Orejinegro, 3/4 Holstein 1/4 Blanco Orejinegro, 5/8 Holstein 3/8 Blanco Orejinegro y Holstein 100%. Se consideraron 6 órdenes de parto. La variable enfermedad podal presenta una distribución binomial. El efecto de los factores se verificó utilizando un modelo lineal generalizado, por medio de una regresión logística (PROC GENMOD SAS versión 9.4). En caso de existir diferencias significativas, se aplicó el procedimiento LSMEANS del SAS (versión 9.4) y un Odds Rattio entre los niveles que presentaron significancia. La prevalencia de enfermedad podal en el hato fue de 10,55%. Los factores de riesgo considerados fueron estadísticamente significativos: componente racial (p < 0,0009), orden parto (p < 0,0001) y peso medio de las vacas (p < 0,0001). Se observó un incremento en la prevalencia de la enfermedad asociado a la raza Holstein, orden de parto alto y bajo peso corporal. La prevalencia de enfermedad podal fue mayor en vacas Holstein puras y menor en vacas Holstein cruzadas con Blanco Orejinegro, debido a la resistencia por heterosis que la raza criolla aporta. El incremento del orden de parto al igual que el bajo peso se relacionan con una mayor prevalencia de esta enfermedad.


ABSTRACT Foot disease is one of the most difficult syndromes to control in the dairy industry. The goal of this study was to quantify the prevalence of foot disease, evaluating its association with factors such as race, calving order and weight. This is a retrospective study using the health and production records of a dairy herd located in the high tropics of Colombia. The racial components present were F1 Holstein x Blanco Orejinegro, 3/4 Holstein 1/4 Blanco Orejinegro, 5/8 Holstein 3/8 Blanco Orejinegro, Holstein 100%. 6 delivery orders were considered. The variable foot disease presents a binomial distribution. The effect of the factors was verified using a generalized linear model, by means of a logistic regression (PROC GENMOD SAS version 9.4). In the event of significant differences, the SAS LSMEANS procedure (version 9.4) and an Odds Ratio were applied between the levels that presented significance. The prevalence of foot disease in the herd was 10,55%. The risk factors considered were statistically significant: racial component (p < 0,0009), calving order (p < 0,0001) and average weight of the cows (p < 0,0001). An increase in the prevalence of the disease was observed associated with the Holstein breed, high calving order and low body weight. The prevalence of foot disease was higher in pure Holstein cows and lower in Holstein cows crossed with Blanco Orejinegro due to the resistance due to heterosis that the creole breed contributes. The increase in the delivery order as well as the low weight are related to a higher prevalence of this disease.

ABSTRACT

Objective@#The aim of this study was to explore the ototoxicity of toluene in the early development of zebrafish embryos/larvae.@*Methods@#Zebrafish were utilized to explore the ototoxicity of toluene. Locomotion analysis, immunofluorescence, and qPCR were used to understand the phenotypes and molecular mechanisms of toluene ototoxicity.@*Results@#The results demonstrated that at 2 mmol/L, toluene induced zebrafish larvae death at 120 hours post fertilization (hpf) at a rate of 25.79% and inhibited the rate of hatching at 72 hpf. Furthermore, toluene exposure inhibited the distance travelled and average swimming velocity of zebrafish larvae while increasing the frequency of movements. As shown by fluorescence staining of hair cells, toluene inhibited the formation of lateral line neuromasts and middle line 1 (Ml @*Conclusion@#This study indicated that toluene may affect the development of both the inner ear and lateral line systems in zebrafish, while the lateral line system may be more sensitive to toluene than the inner ear.

ABSTRACT

BACKGROUND@#Among former Olympic-level athletes, engagement in different sport disciplines has been associated with mortality risk in subsequent years. However, limited evidence is available on whether engagement in different sport disciplines at a young age is associated with locomotive syndrome (LS) risk later in life. This study examined the relationship between engagement in different sport disciplines during university years and LS risk in older age among former university athletes.@*METHODS@#Participants were 274 middle-aged and 294 older men alumni who graduated from a school of physical education in Japan. LS risk was defined as answering "yes" to any of the Loco-check questions. Data on university sports club membership were collected using questionnaires. University clubs were classified into three groups of cardiovascular intensity (low, moderate, high), following the classification system of sport disciplines by the American College of Cardiology. This classification considers the static and dynamic components of an activity, which correspond to the estimated percent of maximal voluntary contraction reached and maximal oxygen uptake achieved, respectively. University clubs were grouped based on the risk of bodily collision (no, yes) and extent of physical contact (low, moderate, high). Relationships between engagement in different sport disciplines and LS risk were analyzed using Cox proportional hazards models, and adjusted for age, height, weight, joint disease, habitual exercise, and smoking and drinking status.@*RESULTS@#Adjusted hazard ratios and 95% confidence intervals associated with the low, moderate, and high cardiovascular intensity sports were 1.00 (reference), 0.48 (0.22-1.06, P = 0.070), and 0.44 (0.20-0.97, P = 0.042) in older men, respectively; however, there was no significant association between these parameters among middle-aged men. Engagement in sports associated with physical contact and collision did not affect LS risk in either group.@*CONCLUSIONS@#Engagement in sports associated with high cardiovascular intensity during university years may reduce the risk of LS in later life. Encouraging young people to participate in such activities might help reduce LS prevalence among older populations.

ABSTRACT

The objective of this study was to examine the safety of multiple repeated percutaneous punctures of cisterna magna for collecting cerebrospinal fluid (CSF) and preliminarily determine the optimal time interval and volume at each collection. Sixty Wistar rats were randomly assigned to six groups: 10 d-0 μL, 10 d-100 μL (100 μL CSF collected at an interval of 10 days), 10 d-150 μL, 15 d-0 μL, 15 d-100 μL, and 15 d-150 μL. CSF was collected by percutaneous puncture of the cisterna magna at four time-points. Simultaneously, locomotor activity, cisterna magna pressure, and acetylcholine levels in the CSF were monitored. Compared with the 10 d-0 μL group, the escape latency by Morris water maze was significantly prolonged in the 10 d-100 μL and 10 d-150 μL groups (P<0.05). Compared with the 15 d-0 μL group, the indices of 15 d-100 μL and 15 d-150 μL groups had no significant differences. When compared with that at the first training, the exception of the 10 d-150 μL and 15 d-150 μL groups, significant differences in escape latency were found at the 6th attempt (P<0.05). Compared with baseline readings for each group, the cisterna magna pressure in the 10 d-150 μL group began to decrease significantly from the third measurement (P<0.05). The optimal time interval during four CSF collections (100 μL per collection) via cisterna magna percutaneous puncture was determined to be 15 days. The procedure did not significantly affect learning processes, performance, or other related indices.

ABSTRACT

ABSTRACT Objective: to analyze prevalence and the factors associated with locomotive syndrome in community-dwelling older adults. Method: a cross-sectional study, developed in a municipal center for the care of older adults in Teresina, Piauí, Brazil. The sample was for convenience and comprised 204 older adults aged 60 years or more, of both genders and with preserved cognitive capacity, according to parameters of the Mini Mental State Examination. Data collection occurred from March to November 2018, by applying a form for sociodemographic, clinical and falls occurrence characterization and the 25-item Geriatric Locomotive Function Scale. To measure the strength of the associations between the variables, odds ratios and 95% confidence intervals were adopted. The statistical significance level was set at 5% for the analyses. Results: the prevalence of locomotive syndrome found was 37.2%. The factors associated with the presence of locomotive syndrome were individual monthly income (p=0.005); existence of one of the following comorbidities: systemic arterial hypertension (p=0.039), osteoporosis (p=0.016), arthrosis (p<0.001) or obesity (p=0.014); and history of hospitalization in the last year (p=0.007). Conclusion: the prevalence of locomotive syndrome found in this study was low and presented higher levels in older adults, with an individual monthly income of two to three minimum wages; who reported having hypertension, osteoporosis, arthrosis or obesity; and with a history of hospitalization in the last year. The health condition investigated showed to be related to aging, with significant repercussions on functionality.

Los factores asociados a la presencia del síndrome locomotor fueron los siguientes: ingreso mensual individual (p=0,005); presencia de una de las comorbilidades: hipertensión arterial sistémica (p=0,039), osteoporosis (p=0,016), artrosis (p<0,001) u obesidad (p=0,014); y antecedentes de internación en el último año (p=0,007). Conclusión: la prevalencia del síndrome locomotor que se encontró en este estudio fue baja y demostró ser superior en adultos mayores, con ingresos mensuales individuales de de dos a tres salarios mínimos; que indicaron sufrir hipertensión, osteoporosis, artrosis u obesidad; y con antecedentes de internación en el último año. La condición de salud investigada demostró estar relacionada con el envejecimiento, con repercusiones significativas sobre la funcionalidad.


RESUMO Objetivo: analisar a prevalência e os fatores associados à síndrome locomotora em idosos comunitários. Método: estudo do tipo transversal, desenvolvido em núcleo de atenção ao idoso, em Teresina, Piauí, Brasil. A amostra foi por conveniência e constituída por 204 idosos com idade igual ou superior a 60 anos, de ambos os sexos, com capacidade cognitiva preservada, segundo parâmetros do Mini Exame do Estado Mental. A coleta de dados ocorreu de março a novembro de 2018, por meio da aplicação de um formulário para caracterização sociodemográfica, clínica e de ocorrência de quedas e da Escala Geriátrica da Função Locomotora de 25 itens. Para aferição da força das associações entre as variáveis, adotaram-se razão de chances e intervalos de confiança de 95%. Nível de significância estatística estabelecido de 5% para as análises. Resultados: a prevalência da síndrome locomotora encontrada foi de 37,2%. Os fatores associados à presença da síndrome locomotora foram renda mensal individual (p=0,005); existência de uma das comorbidades: hipertensão arterial sistêmica (p=0,039), osteoporose (p=0,016), artrose (p<0,001) ou obesidade (p=0,014); e histórico de hospitalização, no último ano (p=0,007). Conclusão: a prevalência da síndrome locomotora encontrada no presente estudo foi baixa e apresentou-se maior em idosos, com renda mensal individual de dois a três salários mínimos; que referiram ter hipertensão, osteoporose, artrose ou obesidade; e com histórico de hospitalização, no último ano.

ABSTRACT

ABSTRACT OBJECTIVE: To evaluate locomotor activity in four field populations of Ae. aegypti with different insecticide resistance profiles from the state of São Paulo for two years. METHODS: This study comprised the susceptible Rockefeller strain and four populations from São Paulo, Brazil: two considered populations with "reduced susceptibility" to pyrethroids (Campinas and Marília), and two "resistant populations" (Santos and Ribeirão Preto). First, 2016 and 2017 eggs from these five populations were hatched in laboratory. Virgin females underwent experiments under laboratory conditions at 25°C, with 12:12h light/dark (LD) photoperiod; 24-hour individual activity was recorded using a locomotor activity monitor (LAM). RESULTS: In females from 2016 field populations, both resistant populations showed significant more locomotor activity than the two reduced susceptibility populations and the Rockefeller strain (p < 0.05). As for females from 2017 field populations, reduced susceptibility populations showed a significant increased locomotor activity than the Rockefeller strain, but no significant difference when compared to Santos resistant population (p > 0.05). CONCLUSIONS: Our results indicate that insecticide-resistant Ae. aegypti populations show increased locomotor activity, which may affect the transmission dynamics of their arboviruses.

ABSTRACT

RESUMEN. El objetivo principal de esta investigación fue evaluar el efecto de un programa de educación física con actividades motrices en niños con discapacidad intelectual inscritos en el Centro de Atención Múltiple de la ciudad de Hermosillo, Sonora. Se realizó un estudio cuantitativo de diseño cuasi-experimental con medias repetidas pretest-postest no aleatorizado, siendo cada participante su propio control. La muestra por conveniencia estuvo conformada por 12 niños en un rango de edad de 7a 10 años (9 ±1.04). La evaluación se llevó a cabo por medio del Inventario de Desarrollo Battelle, el cual se aplicó al inicio y al final del programa, el cual tuvo una duración de tres meses. Se utilizó material didáctico reciclado para estimular los aspectos motrices que se deseaban. Los resultados muestran cambios significativos en la coordinación corporal y en locomoción (p=0.006). Se concluye que aplicar un programa de educación física con actividades motrices de manera regular, a niños con discapacidad, puede contribuir desarrollar de mejor manera las habilidades de motricidad superando su edad equivalente.


ABSTRACT. The main objective of this research was to evaluate the effect of a physical education program with motor activities in children with intellectual disabilities enrolled in the Multiple Attention Center of the city of Hermosillo, Sonora. A quantitative study of quasi-experimental design with repeated means pretest-posttest non-randomized, with each participant being his/her own control was carried out. The convenience sample consisted of 12 children in an age range of 7to 10 years (9 ±1.04). The evaluation was carried out by means of the Battelle Development Inventory, which was applied at the beginning and at the end of the three-month program. Recycled didactic material was used to stimulate the desired motor aspects. The results show significant changes in body coordination and locomotion (p=0.006). It is concluded that applying a physical education program with motor activities on a regular basis to children with disabilities can contribute to better develop motor skills beyond their age equivalent.

ABSTRACT

RESUMO. Este estudo teve como objetivo investigar a percepção de educadoras frente às necessidades de duas bebês com deficiência física em contexto de inclusão na creche. Realizou-se um estudo de caso múltiplo, com seis educadoras que atendiam a turma de Mariana (24 meses), e quatro educadoras que atendiam a turma de Vitória (18 meses), as quais responderam uma entrevista semiestruturada. Ambas as bebês tinham deficiência física e frequentavam escolas de educação infantil da rede pública de Porto Alegre. Os dados foram analisados através de diversas leituras do material, produzindo um relato clínico. Em relação à Mariana, as educadoras destacaram a necessidade de estímulo e de suporte físico à bebê, bem como a importância do afeto na relação educadora-bebê, presente em um 'olhar a mais', mais sensível. Quanto à Vitória, as educadoras reforçaram a importância da integração entre as áreas da saúde e da educação, assim como de um olhar mais atento às diferentes necessidades da bebê com deficiência. A partir dos resultados, foi possível compreender nesse 'olhar a mais', destacado pelas educadoras como necessário para atender à demanda das bebês com deficiência física, uma exigência de maior disponibilidade corporal e psíquica.

ABSTRACT. This study aimed to investigate the perception of educators regarding the needs of two babies with physical disabilities in the context of inclusion in the day care center. A multiple-case study was carried out. The participants were six educators who oversaw Mariana's class, and four educators who oversaw Vitoria's class, and all 10 educators answered a semi-structured interview. Both babies were physically disabled and attended public schools in Porto Alegre/Brazil. The data were analyzed through several readings of the material, which resulted in a clinical report. In relation to Mariana (age 24 months) the educators emphasized the baby's need for stimuli and physical support, as well as the importance of affection in the educator-baby relationship, which was present as a more sensitive 'extra thought'. As for Vitória (age 18 months), educators reinforced the importance of integration between the health and education fields, as well as closer attention to the different needs of the disabled baby. Based on the results, it was possible to observe within that 'extra thought' - highlighted by the educators as necessary to fulfill the needs of babies with physical disabilities - a demand for greater physical and psychic availability.

ABSTRACT

INTRODUCCIÓN: Cuando se evalúa el desarrollo neurocognitivo de bebes alimentados exclusivamente con leche humana en relación a sucedáneos, se encuentra que el desarrollo neuroconductual de los niños alimentados exclusivamente al pecho es superior. OBJETIVO: determinar la relación existente entre el tipo de alimentación de los lactantes y la edad de gateo, en la unidad de atención médica inmediata de pacientes pediátricos del Hospital Julio Criollo Rivas. Octubre 2018 ­ febrero 2019. Ciudad Bolívar, Estado Bolívar. METODOLOGÍA: fue un estudio de campo, de corte transversal, analítico, comparativo de casos y controles no experimental, conformado por el 30% de los lactantes menores aparentemente sanos entre 5 meses y un año de edad, que consumen lactancia materna exclusiva y lactancia artificial, atendidos en la unidad de atención médica inmediata del hospital "Julio Criollo Rivas" de Ciudad Bolívar, estado Bolívar. RESULTADOS: Durante el período de estudio, fueron evaluados 200 pacientes y se obtuvo que, de 43 pacientes que recibieron lactancia materna exclusiva hasta los 6 meses, el 51,16% (n=22) adquirieron la habilidad de gateo a los 7 meses, y de 157 pacientes que tuvieron ablactación precoz sólo el 32,48% (n=51) adquirieron la habilidad de gateo a los 7 meses. CONCLUSIONES: existe influencia de la lactancia materna en la adquisición de la habilidad de gateo, observándose adquisición precoz de la misma en el grupo que recibió lactancia materna exclusiva hasta los 6 meses de edad.


INTRODUCTION: When evaluating the neurocognitive development of babies exclusively fed with human milk in relation to substitutes, it is found that the neurobehavioral development of children fed exclusively to the breast is superior. OBJECTIVE: to determine the relationship between the type of feeding of the infants and the age of crawling, in the unit of immediate medical attention of pediatric patients of the Hospital Julio Criollo Rivas. October 2018 - February 2019. Ciudad Bolívar, Bolívar State.

ABSTRACT

Resumen La locomoción con miembros implica diferentes desafíos de tipo mecánico: en cada ciclo, los segmentos deben reposicionarse anatómicamente, con fases de aceleración y deceleración y la consiguiente elevación y descenso del centro de masa. Dentro de la locomoción humana, la marcha y la carrera son actividades fundamentales en todo el ciclo vital humano. En específico, la carrera es una actividad muy estudiada por las ciencias del deporte, medicina, fisioterapia o kinesiología, ingeniería y biología, por el alto impacto articular y muscular que genera, ya que esta trae consigo lesiones y alteraciones en el rendimiento de los pacientes y deportistas. El constante estudio de la locomoción ha reconocido diferentes desafíos de tipo fisiológico y mecánico, tanto en la explicación de fenómenos como en el análisis de estos. Este artículo busca aclarar conceptos a través de textos clásicos, que se consideran básicos e importantes para entender las investigaciones posteriores. Además, se explican diferentes parámetros que sirven para comprender la locomoción, tanto en estudios con humanos como en animales. El objetivo de este trabajo es hacer una revisión de la literatura, que se enfoca en los aspectos mecánicos, energéticos, el efecto del tamaño y los diferentes patrones de la locomoción, con sus modelos mecánicos. Finalmente, los autores esperan que este texto sea un aporte para docentes y estudiantes para la comprensión de la locomoción en idioma español.


Abstract Limbed locomotion involves different mechanical challenges: in each cycle, limbs must be repositioned anatomically, with acceleration and deceleration phases and the consequent raising and lowering of the center of mass. As part of human locomotion, walking and running are fundamental activities throughout the life cycle. In particular, running has been highly studied by sports sciences, medicine, physiotherapy, kinesiology, engineering, and biology due to the high joint and muscular impact it generates, commonly causing injuries and alterations in the performance of patients and athletes. The constant study of locomotion has brought to light the different physiological and mechanical challenges when explaining and analyzing phenomena. Using classical texts, this article aims to clarify concepts considered basic and important to understand further research. In addition, different parameters needed to understand locomotion, both in human and animal studies, are explained. The objective of this paper is to review the literature focused on the mechanical and energetic aspects of locomotion, the effect of size, and the different locomotion patterns and mechanical models. Finally, this paper is presented as a contribution for teachers and students to understand locomotion in the Spanish language.


Resumo A locomoção com membros implica diferentes desafios do tipo mecânico: em cada ciclo, os segmentos devem ser reposicionados anatomicamente, com fases de aceleração e desaceleração e a subsequente elevação e descenso do centro de massa. Dentro da locomoção humana, a marcha e a corrida são atividades fundamentais em todo o ciclo vital humano. Especificamente, a corrida é uma atividade muito estudada pelas ciências do esporte, medicina, fisioterapia ou cinesiologia, engenharia e biologia, devido à geração de alto impacto articular e muscular, trazendo consigo lesões e alterações no rendimento dos pacientes e esportistas. O constante estudo da locomoção reconheceu diferentes desafios de tipo fisiológico e mecânico, tanto na explicação de fenômenos como na análise destes. Este artigo busca aclarar conceitos através de textos clássicos, considerados básicos e importantes para entender as pesquisas posteriores. Além disso, são explicados diferentes parâmetros que servem para compreender a locomoção, tanto em estudos com humanos quanto com animais. O objetivo deste trabalho é fazer uma revisão da literatura, que se enfoca nos aspectos mecânicos, energéticos, no efeito do tamanho e nos diferentes padrões da locomoção, com seus modelos mecânicos. Finalmente, os autores esperam que este texto, em espanhol, seja uma contribuição para docentes e estudantes para a compreensão da locomoção.

ABSTRACT

O objetivo do presente estudo foi revisar os conceitos relativos ao funcionamento e alterações da supressão do reflexo vestíbulo-ocular (SRVO) e as principais formas de avaliação atualmente. Trata-se de uma pesquisa descritivo-exploratória, baseada em uma revisão da (El trabajo es una investigación descriptiva-exploratoria, basada en una revisión de la) literatura, realizada no (en el) Portal de Periódicos da Capes, no período de abril de 2020. Os (Los) operadores booleanos utilizados foram vestibulo-ocular reflex (OR), semicircular canal (OR), vestibular (AND) suppression. Como estratégia de pesquisa, na (en la) etapa de triagem (selección) foram utilizados os filtros: descritores no (en) título, publicações dos (de los) últimos dez anos, tipo de material, idioma e artigos revisados por pares. Dos 30 artigos triados (seleccionados), 20 apresentaram resumo de acordo com o tema e 13 estudos atenderam aos critérios de incluso (presentaron resúmenes relacionados al tema y 13 estudios cumplieron los criterios de inclusión). Scopus, Medline/PubMed e Science Citation Index Expanded foram as bases mais abrangentes (fueron las bases más abarcativas). A maioria dos (La mayoría de los) estudos, sobretudo os mais recentes, utilizaram os testes de impulso cefálico com o paradigma ´suppression head impulse test´ (SHIMP) comparando-o ao ´head impulse test´ (HIMP). A cadeira rotatória (La silla rotatoria) com eletronistagmografia foi o segundo teste mais utilizado. Apenas um estudo utilizou a Scleral Search Coil. A partir dessa revisão constata-se que a SRVO é influenciada pela idade, pode ser alterada por disfunções vestibulares periféricas unilaterais ou bilaterais, mas também por alterações neurológicas, como as cerebelares (las cerebelosas). Além da via visual, a SRVO pode ser desencadeada por fontes auditivas, somestésicas e até mesmo imagéticas (e incluso imaginativas, fantasiosas)


The present study aimed to review the concepts related to the functioning and changes in vestibular-ocular reflex suppression (VORS) and the most used assessments today. This is descriptive-exploratory research, based on a literature review, carried out on the Capes Journals Portal, in April 2020. The Boolean operators used were Vestibulo-ocular reflex (OR) Semicircular canal (OR) Vestibular (AND) Suppression. As a research strategy, in the screening stage, with the filters: descriptors in the title, last ten years, type of material, language, and peer-reviewed articles. Thirty articles were screened, 20 presented a summary according to the theme and 13 studies met the inclusion criteria. Scopus, Medline/PubMed, and Science Citation Index Expanded were the most comprehensive databases. Most studies, especially the most recent ones, used cephalic impulse tests with the SHIMP paradigm (suppression head impulse test) comparing it to the HIMP (head impulse test, HIMP). The rotary chair with electronystagmography was the second most used test. Only one study used the Scleral Search Coil. From this review, it appears that the SRVO is influenced by age; it can be altered by unilateral or bilateral peripheral vestibular disorders, but also by neurological changes, such as the cerebellar ones. In addition to the visual pathway, other sources can trigger SVOR, such as auditory, somesthetic and even imagery sources
