Stable oxygen and carbon isotope of foraminifera from DSDP Leg 90 sites

High-resolution oxygen and carbon isotope stratigraphy is presented for Miocene to early Pliocene sequences at three DSDP sites from the Lord Howe Rise, southwest Pacific, at water depths ranging from 1,300 to 2,000 m. Site 588 is located in the warm subtropics (~26°S), whereas Sites 590 and 591 are positioned in transitional (northern temperate) water masses (~31°S). Benthic foraminiferal oxygen and carbon isotope analyses were conducted on all sites; planktonic foraminiferal isotope data were generated for Site 590 only. Sample resolution in these sequences is on the order of 50,000 yr. or better. The chronological framework employed in this study is based largely upon ages assigned to Neogene calcareous nannoplankton boundaries. The benthic oxygen isotope record exhibits several major features during the Neogene. During most of the early Miocene, delta18O values were relatively low, reaching minimum values in the late early Miocene (19.5 to 16.5 Ma), and recording the climax of Neogene warmth. This was followed by a major increase in benthic delta18O values between ~16.5 and 13.5 Ma, which is interpreted as representing major, permanent accumulation of the East Antarctic ice sheet and cooling of bottom waters. During the 3 m.y. 18O enrichment, surface waters at these middle latitudes warmed between 16 and 14.5 Ma. During the remainder of the middle and late Miocene, benthic delta18O values exhibit distinct fluctuations, but the average value remained unchanged. The isotopic data show two distinct episodes of climatic cooling close to the middle/late Miocene boundary. The earliest of these events occurred between 12.5 and 11.5 Ma in the latest middle Miocene. The second cooling event occurred from 11 to 9 Ma, and is marked by some of the highest delta18O values of the entire Miocene. This was followed by relative warmth during the middle part of the late Miocene. The latest Miocene and earliest Pliocene (6.2 to 4.5 Ma) were marked by relatively high delta18O values, indicating increased cooling and glaciation. During the middle Pliocene, at about 3.4 Ma, a 0.4 per mil increase in benthic delta18O documents a net increase in average global ice volume and cooling of bottom waters. During this interval of increased glaciation, surface waters warmed by 2-3°C in southern middle-latitude regions. During the late Pliocene, between 2.6 and 2.4 Ma, a further increase in delta18O occurred; this has been interpreted by previous workers as heralding the onset of Northern Hemisphere glaciation. Surface-water warming in the middle latitudes occurred in association with major high-latitude glacial increases in the early middle Miocene (16-14 Ma), middle Pliocene (-3.5 Ma), and late Pliocene (~2.4 Ma). These intervals were also marked by increases in the vertical temperature gradient in the open ocean. Intersite correlation is enhanced by using carbon isotope stratigraphy. The great similarity of the delta13C time-series records within and between ocean basins and with water depth clearly indicates that changes in oceanwide average delta13C of [HCO3]- in seawater dominated the records, rather than local effects. Broad changes in the Neogene delta13C record were caused largely by transfer of organic carbon between continental and oceanic reservoirs. These transfers were caused by marine transgressions and regressions on the continental margins. The dominant feature of Neogene delta13C stratigraphy is a broad late early to early middle Miocene increase of about lâ between ~19 and 14.5 Ma. This trend occurred contemporaneously with a period of maximum coastal onlap (transgression) and maximum Neogene climatic warmth. The delta13C trend terminated during the expansion of the Antarctic ice sheet and associated marine regression. The latest Miocene carbon isotope shift (of up to - 0.75 per mil) at 6.2 Ma is clearly recorded in all sites examined and was followed by relatively low values during the remainder of the Neogene. This shift was caused by a glacioeustatic sealevel lowering that exposed continental margins via regression and ultimately increased the flux of organic carbon to the deep sea. An increase in delta13C values during the early Pliocene (~5 to 4 Ma) resulted from marine transgression during a time of global warmth.

Foraminiferal oxygen and carbon isotopic measurements from 5 sites of southern Atlantic and Pacific

The stratigraphy and paleoceanography of the late Miocene and early Pliocene have been examined at six sites in the South Atlantic and southwest Pacific oceans: Deep Sea Drilling Project (DSDP) sites 284, 516A, 519, 588, and 590 and two piston cores from Chain cruise 115. A consistent stratigraphy was developed among sites using graphic correlation, which resulted in age models for all sites that are tied to the revised paleomagnetic time scale of Berggren et al. (1985). Applying these chronologies, we assessed latitudinal and interocean contrasts in the stratigraphic ranges of late Miocene-early Pliocene planktonic foraminiferal and nanno - fossil datums. Salient stratigraphic results include (1) The last appearance datum (LAD) of Globoquadrina dehiscens is a late Miocene (approx. 6.4 Ma) event in the subtropics and is not useful for the placement of the Miocene/Pliocene (M/P) boundary in this biogeographic province. (2) The first appearance datum (FAD) of Globorotalia crassaformis occurred at 5.1 Ma in the South Atlantic near the M/P boundary, suggesting that Gr. crassaformis may have first evolved in the South Atlantic and later migrated to other regions. (3) In the southwest Pacific, the FADs of Gr. margaritae (5.97 Ma), Gr. puncticulata (5.09 Ma), and Gr. crassaformis (4.87 Ma) are significantly time transgressive between temperate and warm subtropical regions. Time lags of 1.0 m.y. were required for these species to adapt to physical and/or biotic conditions peripheral to their endemic biogeographic provinces. (4) Between the subtropics of the South Atlantic and southwest Pacific, many planktonic foraminiferal datums (FAD of Dentogloboquadrina altispira, Gr. cibaoensis, Gr. conomiozea, Gr. margaritae, and Gq. dehiscens and LAD of Gr. cibaoensis) markedly depart from the correlation suggested by magnetostratigraphy, indicating that these datum levels are unreliable for correlation between these ocean basins. (5) In contrast, available calcareous nannofossil datum levels fall on or near the paleomagnetic correlation line, indicating synchroneity of events within the subtropics. (6) Biostratigraphic, magnetic, and 87Sr/86Sr correlation between sites 588 and 519 and the M/P neostratotype at Capo Rossello, Sicily, suggests that the base of the Zanclean stratotype occurs at 5.1-5.0 Ma in the lower reversed subchron of the Gilbert, about 2-3 * 10**5 years above the Gilbert/Chron 5 boundary. Oxygen isotopic results from DSDP sites 284, 519, and CH115 piston cores confirm a prolonged benthic d18O increase in the latest Miocene between 5.6 and 5.0 Ma, as originally proposed by Shackleton and Kennett (1975). At DSDP site 588, the benthic d18O record in the latest Miocene is marked by high-frequency fluctuations with amplitude variations of 0.5per mill, and a long-period wavelength component of 400,000 years. Maximum d18O values, however, occurred during the late Miocene (Kapitean Stage) between 5.5 and 5.1 Ma. The late Miocene d18O changes resulted from mid- and high-latitude cooling and pulses of ice sheet expansion and contraction. Glacial events were most intense during the latest Miocene (Kapitean Stage), and occurred at 5.50-5.35 Ma and at 5.10 Ma. Glacial events are estimated to have lowered sea level by 40 to 60 m and contributed to the isolation and desiccation of the Mediterranean Basin during the late Messinian. Interglacial conditions prevailed at 5.2 Ma and between 5.0 and 4.1 Ma in the early Pliocene. The beginning of the Pliocene was marked by changes in many proxy climatic indicators at all sites, suggesting a prolonged interval of warm, interglacial conditions between 5.0 and 4.1 Ma during the earliest Pliocene.

Avaliação da pressão inspiratória nasal sniff na população obesa

Introdução: a avaliação da pressão inspiratória nasal (SNIP) é considerada uma manobra complementar da Pressão Inspiratória Máxima estática (PImax) em várias condições clínicas, porém não há relatos na obesidade. Por outro lado, a obesidade tem um importante impacto nos músculos respiratórios especialmente com maiores gordura abdominal o que provavelmente pode ser detectado na avaliação da SNIP que mensura mais precisamente a pressão diafragmática. Objetivo: analisar em obesos a relação entre SNIP e variáveis respiratórias e marcadores de adiposidade. Material e Método: num estudo transversal um total de 92 obesos (38.3±10.2 anos) sem história de doença respiratória ou cardíaca diagnosticada. Foram avaliados na espirometria (capacidade vital forçada-CVF; volume expiratório forçado no primeiro segundo-VEF1; volume de reserva expiratório-VRE) e pressões respiratórias estática (PImax, PEmax e SNIP) e dinâmica (ventilação voluntária máxima-VVM). Sendo considerados os marcadores de adiposidade: índice de adiposidade corporal-IAC; índice de massa corporal-IMC e circunferências do quadril (CQ), cintura (CC) e pescoço (CP). Resultados: 65 obesos mórbidos (IMC=50.8±8.1Kg/m2) e 27 obesos não mórbidos (IMC=35.6±2.7Kg/m2) foram homogêneos (p>0.05) na SNIP (99.1±24.5cmH2O, 87% do predito) e PImax (107.3±26.4cmH2O, 109% do predito). Existe correlação (r=0.5) entre SNIP e PImax somente no grupo de obesos mórbidos. De acordo com as correlações houve associação entre variáveis respiratórias (CVF r=0.48; VEF1 r=0.54; e VVM r=0.54), valores antropométricos (idade r=-0.44) e SNIP somente para os obesos mórbidos. Esses achados foram certificados quando também comparados a quantidade de gordura ao redor do pescoço (CP≥43cm). O modelo de regressão linear stepwise mostrou que a VVM parece ser o melhor preditor para explicar a SNIP nos obesos mórbidos. Nestes obesos a SNIP foi levemente mais baixa (87%predito) que os valores esperados para indivíduos brasileiros saudáveis. Conclusão: em obesos mórbidos a SNIP é moderadamente relacionada a PImax. A SNIP parece ser mais relacionada a VVM que à marcadores de adiposidade.

Parâmetros bioquímicos e níveis de IgE total e específicas para aeroalérgenos em mulheres obesas com síndrome dos ovários policísticos

Introduction: Polycystic ovary syndrome (PCOS) whose classic features (menstrual irregularity of oligo/ amenorrhea type, chronic anovulation, infertility and hyperandrogenism clinical and/ or biochemical), is associated with aspects of metabolic syndrome (MS), as obesity and insulin resistance. The level of obesity determines different levels of inflammation, increasing cytokines participants of metabolic and endocrine functions, beyond modulate the immune response. Metabolic changes, added to the imbalance of sex hormones underlying irregular menstruation observed in (PCOS) can trigger allergic processes and elevation of total and specific IgE antibodies indicate that a sensitization process was started. Objective: To evaluate the influence of PCOS on biochemical parameters and levels of total and specific IgE to aeroallergens in obese women. Methods: After approval by the Committee of Ethics in Research, were recruited 80 volunteers with BMI ≥ 30 kg/m2 and age between 18 and 45 years. Among these, 40 with PCOS according to the Rotterdam criteria and 40 women without PCOS (control group). All participants were analysed with regard to anthropometric, clinical, gynecological parameters, interviewed using a questionnaire, and underwent blood sampling for realization of laboratory tests of clinical biochemistry: Total cholesterol, LDL-cholesterol, HDL- cholesterol, Triglycerides, Fasting glucose, Urea, Creatinine, Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) and immunological: total and specific IgE to Dermatophagoides pteronyssinus, Blomia tropicalis, Dermatophagoides farinae and Dermatophagoides microceras.Statistical analysis was performed using SPSS 15.0 software through the chi-square tests, Fisher, Student t test and binary logistic regression, with significance level (p <0.05). Results: It was observed in the group of obese women with PCOS that 29 (72.5%) had menstrual cycle variable and 27 (67.5%) had difficulty getting pregnant. According to waist-hip ratio, higher average was also observed in obese PCOS (0.87). Blood level of HDL (36.9 mg/dL) and ALT (29.3 U/L) were above normal levels in obese women with PCOS, with statistically significant relationship. In the analysis of total and specific IgE to D. pteronyssinus high results were also prevalent in obese PCOS, with blood level (365,22 IU/mL) and (6.83 kU/L), respectively, also statistically significant. Conclusions: Observed predominance of cases with high levels of total IgE in the group of obese women with PCOS, 28 (70%) of the participants, whose mean blood concentration of the group was 365.22 IU/mL. In the analysis of Specific IgE between the groups, the allergen Dermatophagoides pteronyssinus showed greater dispersion and average the results of sensitization in the group of obese PCOS, whose mean blood concentration was 6.83 kU/l.

Efeitos do treino resistido na capacidade funcional e na reatividade pressórica em pacientes intradialíticos

Pacientes com doença renal crônica (DRC) submetidos ao treinamento resistido durante a hemodiálise apresentam benefícios substanciais dos sistemas muscular e cardiovascular, da capacidade funcional e da sua qualidade de vida. Entretanto, as melhorias na reatividade pressórica ainda não estão bem esclarecidas. O objetivo foi analisar o efeito do treino resistido na melhora da capacidade funcional e da reatividade pressórica em pacientes hemodialisados, em Natal/RN no ano de 2014. Trata-se de um ensaio clínico controlado e randomizado, com amostra de 64 pacientes, com média de idade de 42,28 (±11,48) anos, distribuídos em grupo experimental (GE) e controle (GC). Para mensurar os ganhos de força de membros inferiores foram utilizados os testes de sentar e levantar e de levantar e caminhar, já para a reatividade pressórica o teste cold pressor, em ambos os grupos antes e após a intervenção. Além disso, apenas o GE participou do treinamento resistido durante a hemodiálise em 16 semanas, composto por 3 sessões semanais, 3 séries de 10 repetições máximas (RM) estimadas (para extensores de joelho e flexores de quadril e joelho), entre 50 a 70% de 10 RM. Para a intensidade do treinamento foi utilizada a escala de Borg entre 11 a 14 durante as seções. Os dados foram analisados utilizando o Teste t para amostras independentes (inter-grupos) bem como para comparar a diferença das médias nos grupos pré e pós-intervenção (intra-grupos) a partir do Teste t para amostras repetidas. Para todas as variáveis foi considerada a significância estatística de 5% executados no software SPSS® 20.0. O estudo foi aprovado pelo comitê de ética do Hospital Universitário Onofre Lopes (HUOL - UFRN) número 37992214.2.0000.5292. Após a intervenção, verificou-se que os pacientes do GE tiveram um desempenho melhor nos testes de força (p<0,001) em comparação ao GC. Resultado também observado na pressão arterial sistólica e diastólica (PAS e PAD) ambas de repouso que apresentaram redução dos níveis pressóricos apenas no GE (p<0,001). Na reatividade pressórica tanto nos períodos pré bem como após 2 minutos também demonstraram reduções estatisticamente significativas do GE (p<0,001 e p=0,012) respectivamente quando comparado ao GC. Conclui-se que o treinamento resistido melhorou desempenho nos testes de força de membros inferiores beneficiando a capacidade funcional dos pacientes em hemodiálise, como também a pressão arterial de repouso e os níveis de reatividade pressórica obtiveram reduções significativas de seus valores após a intervenção. Além disso, este tipo de treinamento também pode ser utilizado como uma estratégia de proteção aos fatores de risco cardiovascular em pacientes renais crônicos.

Estudo comparativo entre antipsicóticos atípicos no tratamento da esquizofrenia e sua influência na qualidade de vida dos pacientes

Schizophrenia is a severe and persistent mental illness; diagnosis occurs mainly during adolescence. The pharmacological treatment is done with typical and atypical antipsychotics. Atypical have the advantage of reduced extrapyramidal effects, which make them promising for the treatment of schizophrenia, furthermore, they have shown significant metabolic and hormonal changes. The objective of this study was to evaluate the influence of atypical antipsychotics, olanzapine and risperidone on the quality of life and on their adverse effects in schizophrenic patients. For this we analyzed the quality of life of patients with implementation of EuroQol-5D-3L instrument and performing biochemical and hormonal tests, blood pressure measurement, and measurement of anthropometric indices, besides the application of Ugvalg scales for Kliniske Undersgelser (UKU) and Simpson-Angus, who evaluated the side effects caused by drugs. Data were analyzed using the Student t test and chi-square test, with 5% significance level. The results showed that the EuroQol the antipsychotic olanzapine causes significant losses associated with personal care (p <0.001). Comparing the two groups of antipsychotics, the average years of quality-adjusted life, known per QALY was favorable for the risperidone group (p <0.032). The results of olanzapine and risperidone groups were compared. In terms of socioeconomic, it was observed that men used, the prevalent form, olanzapine (p <0.008); this same group showed the following results significantly unfavorable, related to anthropometric variables: waist circumference (p <0.01), hip circumference (p <0.02), weight (p <0.02) and blood pressure (p <0.04). The biochemical and hormonal analyzes showed that olanzapine resulted in losses related to the following variables: triglycerides (p <0.04), HDL cholesterol in men (p < 0.02) and cortisol (p < 0.01). In risperidone users, the only negative value was prolactin (p < 0.04). Regarding the analysis of the Simpson-Angus scale, the group treated with olanzapine was handicapped because the average total scores for olanzapine was 0.38, while for risperidone was 0.11 (p < 0.02). In the UKU scale, the following results were obtained also unfavorable for the olanzapine group: fatigue (P <0.02), dystonia (p <0.01) and tremor (p <0.03). According to the UKU scale, the side effects present in the risperidone group included: gynecomastia (p <0.01), ejaculatory dysfunction (p <0.02) and erectile dysfunction (p <0.02). It was concluded that olanzapine users had the worst score of quality of life, higher metabolic risks associated with overweight and inadequate lipid profile and greater tendency to extrapyramidal manifestations. However, risperidone users were more likely to adverse reactions due to hormonal changes.

Efeitos do treino de marcha em esteira com adição de carga ao membro inferior não parético de indivíduos com acidente vascular cerebral: ensaio clínico controlado e randomizado

Introduction: Gait after stroke is characterized by a significant asymmetry between the lower limbs, with predominant use of the non-paretic lower limb (NPLL) over using the paretic lower limb. Accordingly, it has been suggested that adding load/weight to the NPLL as a form of restricting the movement of this limb may favor the use of the paretic limb, reducing interlimb asymmetry. However, few studies have been conducted up to this moment, which only investigated the immediate effects of this practice. Objectives: 1) Investigating whether there is an influence of adding load to the NPLL during treadmill training on cardiovascular parameters and on gait performance of individuals with stroke, compared to treadmill training without load addition; 2) Analyzing the effects of treadmill training with and without load added to the NPLL on kinematic parameters of each lower limb during gait; 3) Analyzing the effects of treadmill training with and without load added to the NPLL on measurements of functional mobility and postural balance of these patients. Materials and Methods: This is a randomized single blinded clinical trial involving 38 subjects, with a mean age of 56.5 years, at the subacute post-stroke phase (with mean time since stroke of 4.5 months). Participants were randomly assigned into an experimental group (EG) or control group (CG). EG (n= 19) was submitted to gait training on a treadmill with the addition of load to the NPLL by ankle weights equivalent to 5% of body weight. CG (n= 19) was only submitted to gait training on a treadmill. Behavioral strategies which included home exercises were also applied to both groups. The interventions occurred daily for two consecutive weeks (Day 1 to Day 9), being of 30 minutes duration each. Outcome measures: postural balance (Berg Functional Balance Scale – BBS), functional mobility (Timed Up and Go – TUG; kinematic variables of 180° turning) and kinematic gait variables were assessed at baseline (Day 0), after four training sessions (Day 4), after nine training sessions (Day 9), and 40 days after completion of training (Follow-up). Cardiovascular parameters (mean arterial pressure and heart rate) were evaluated at four moments within each training session. Analysis of variance (ANOVA) was used to compare outcomes between EG and CG in the course of the study (Day 0, Day 4, Day 9 and Follow-up). Unpaired t-tests allowed for intergroup comparison at each training session. 5% significance was used for all tests. Results: 1) Cardiovascular parameters (systemic arterial pressure, heart rate and derivated variables) did not change after the interventions and there were no differences between groups within each training session. There was an improvement in gait performance, with increased speed and distance covered, with no statistically significant difference between groups. 2) After the interventions, patients had increased paretic and non-paretic step lengths, in addition to exhibiting greater hip and knee joint excursion on both lower limbs. The gains were observed in the EG and CG, with no statistical difference between the groups and (mostly) maintained at follow-up. 3) After the interventions, patients showed better postural balance (higher scores on BBS) and functional mobility (reduced time spent on the TUG test and better performance on the 180° turning). All gains were observed in the EG and CG, with no statistically significant difference between groups and were maintained at follow-up. Conclusions: The addition of load to the NPLL did not affect cardiovascular parameters in patients with subacute stroke, similar to treadmill training without load, thus seemingly a safe training to be applied to these patients. However, the use of the load did not bring any additional benefits to gait training. The gait training program (nine training sessions on a treadmill + strategies and exercises for paretic limb stimulation) was useful for improving gait performance and kinematics, functional mobility and postural balance, and its use is suggested to promote the optimization of these outcomes in the subacute phase after stroke.

Propriocepção de deficientes visuais : Treinamento funcional como possibilidade interventiva

A deficiência visual (DV) é uma limitaçao sensorial que pode comprometer o desenvolvimento motor, afetivo, social e cognitivo do ser humano. No mundo esta limitaçao acomete 39 milhoes de pessoas. No Brasil, existem aproximadamente 6,5 milhoes de DV. O treinamento funcional trabalha de forma integrada, por meio de movimentos multiarticulares e multiplanares que envolvem o sistema proprioceptivo, estando relacionado com a sensaçao de movimento (sinestesia) e posiçao articular. Desta forma, o objetivo desse estudo foi analisar os efeitos do treinamento funcional na propriocepçao de deficientes visuais. O programa de treinamento teve duraçao de 12 semanas, com sessoes bi-semanais das quais participaram oito indivíduos, cinco com baixa visao e três com cegueira total. A avaliaçao da propriocepçao de membros superiores foi realizada com um cinesiômetro, e a avaliaçao de membros inferiores foi realizada com a fixaçao de um flexímetro na articulaçao do joelho do membro dominante do participante. Os resultados evidenciaram melhoras discretas para dois ângulos de membros superiores, porém nos membros inferiores a margem de erro foi bem inferior que nos membros superiores

Pedagogía y política. La campaña de alfabetización CREAR en la historia reciente de la educación de adultos en la Argentina de los '70

La tesis que presentamos es el resultado de un trabajo de investigación sobre la campaña de alfabetización CREAR realizada entre 1973 y 1975. La Campaña de Reactivación de la Educación del Adulto para la Reconstrucción, estuvo dirigida por la Dirección Nacional de Educación de Adultos (DINEA) en la etapa de la recuperación democrática luego de dieciocho años de gobiernos autoritarios combinados con la proscripción de la fuerza política mayoritaria. Apoyada en el registro testimonial de quienes fueron sus inspiradores, conductores, coordinadores, alfabetizadores, la investigación se propone analizar la articulación entre pedagogía y política durante la realización de la campaña. Los testimonios rescatados en la presente investigación, representan figuras destacadas de la campaña de alfabetización en su doble dimensión de pedagogos y militantes políticos. En esta dirección, la presente tesis se propone recuperar los principales debates y discusiones que se generaron en torno a su desarrollo a partir de quienes fueron sus testigos. ¿Qué sueños proyectaban en la alfabetización? ¿Qué formas de imbricación entre lo político y lo pedagógico se produjo en su desarrollo? ¿Cómo se plasmó dicha articulación? ¿Sobre qué ejes vertebraron su discurso? Entre la pedagogía de la liberación y la doctrina del peronismo ¿qué lectura predominó? El desarrollo de este trabajo de investigación se propone invitar a recorrer este camino cargado de tensiones y contradicciones que, esperamos, se convierta en una contribución al campo de la historia de la educación reciente de la Argentina

Temos direcionado nossas açoes ao ensino, à pesquisa e à extensao. Neste percurso, construímos outra organizaçao e articulaçao entre saberes e conhecimentos ? a ambientalizaçao do currículo

Propriocepção de deficientes visuais : Treinamento funcional como possibilidade interventiva

A deficiência visual (DV) é uma limitaçao sensorial que pode comprometer o desenvolvimento motor, afetivo, social e cognitivo do ser humano. No mundo esta limitaçao acomete 39 milhoes de pessoas. No Brasil, existem aproximadamente 6,5 milhoes de DV. O treinamento funcional trabalha de forma integrada, por meio de movimentos multiarticulares e multiplanares que envolvem o sistema proprioceptivo, estando relacionado com a sensaçao de movimento (sinestesia) e posiçao articular. Desta forma, o objetivo desse estudo foi analisar os efeitos do treinamento funcional na propriocepçao de deficientes visuais. O programa de treinamento teve duraçao de 12 semanas, com sessoes bi-semanais das quais participaram oito indivíduos, cinco com baixa visao e três com cegueira total. A avaliaçao da propriocepçao de membros superiores foi realizada com um cinesiômetro, e a avaliaçao de membros inferiores foi realizada com a fixaçao de um flexímetro na articulaçao do joelho do membro dominante do participante. Os resultados evidenciaram melhoras discretas para dois ângulos de membros superiores, porém nos membros inferiores a margem de erro foi bem inferior que nos membros superiores
