Estudo comparativo da marcha de indivíduos hemiparéticos no solo e na esteira

The purpose of the study was to compare hemiparetic gait overground and on the treadmill. Seventeen chronic stroke patients were included in the study. They walked overground and on a treadmill level at the same speed. The Qualisys Medical AB motion analysis system was used to quantify the joint kinematic of the paretic lower limb and the spatio-temporal parameters on the two conditions: overground walking and treadmill walking on three samples of 5-minutes. During the first sample, the subjects walked on the treadmill with greater cadence, shorter stride length, shorter step time on the lower paretic limb, greater range of motion in the hip and knee, greater knee flexion at the initial contact, more extension of the knee and lower dorsiflexion of the ankle at the stance phase. It is important to emphasize that the maximal knee flexion and ankle dorsiflexion just occurred later on the treadmill. Comparisons between each walking sample on the treadmill hadn t revealed any changes on the gait parameters over time. Nonetheless, when analyzing the third walking sample on the treadmill and overground, some variables showed equivalence as such as the total range of motion of the hip, the knee angle at the initial contact and its maximal extension at the stance phase. In summary, walking on a treadmill, even thought having some influence on the familiarization process, haven t demonstrated a complete change in its characteristics of hemiparetic chronic patients

Efeitos do treinamento de marcha sobre superfícies inclinadas em indivíduos com hemiparesia crônica: ensaio clínico controlado randomizado

Among the therapeutic approaches that can be used to achieve this goal is the gait training on sloping surfaces, but there are few scientific findings that elucidate the results of this practice. OBJECTIVE: To evaluate the effects of training on sloping surfaces on the gait of subjects with chronic hemiparesis. MATERIALS AND METHODS: A controlled, randomized, blinded clinical trial was conducted. Concluded the study twenty-four subjects with age between 40 and 70 years (54,91±9,3). Their neurological function, functional independence, motor function and balance assessed, besides the gait evaluation through kinemetry. The subjects were allocated into two groups: control group (CG) underwent gait training on treadmill with partial body weight support (PBWS) without inclination; and the experimental group (EG) submitted to gait training on treadmill with PBWS and inclination of 10%. Twelve training sessions were performed. The paired t Student test and Wilcoxon test were used in statistical analysis to compare findings before and after training for each group, and the t student test for independent samples and Mann-Whitney.test were used to compare the to groups. RESULTS: After training within-group changes were observed on balance recovery, motor function and functionality, in both experimental conditions. The EG showed changes after training on speed, stride length, step length of paretic and non-paretic side, paretic single support, double support time and non-paretic swing time. The CG the differences were detected on double support, paretic single support and hip range of movement. The EG showed better results when compared to CG on the variables: speed (p=0,034), non-paretic single support (p=0,02) and paretic swing time (p=0,02). CONCLUSION: gait training on sloping surfaces represents a promising strategy for gait training of subjects with chronic hemiparesis since it is can influence a greater number of gait variables, when compared with gait training on flat surface

Efeitos da adição de carga no treino de marcha na esteira em indivíduos com Doença de Parkinson: ensaio clínico controlado randomizado

Introduction: The intrinsic gait disorders in individuals with Parkinson's disease (PD) are one of the most disabling motor symptoms. Among the therapeutic approaches used in attempts to improve the motor function, especially the gait pattern of individuals, stands out the treadmill gait training associated with the addition of load. However, there are few findings that elucidate the benefits arising from such practice. Objective: To assess the effects of adding load on the treadmill gait training in individuals with PD. Material and Methods: A controlled, randomized and blinded clinical trial, was performed with a sample of 27 individuals (18 men and 9 women) with PD, randomly assigned to three experimental conditions, namely: treadmill gait training (n=9), treadmill gait training associated with addition of 5% load (n=9) and treadmill gait training associated with addition of 10% load (n=9). All volunteers were assessed, during phase on of Parkinson's medication, regarding to demographic, clinical and anthropometric (identification form) data, level of disability (Hoehn and Yahr Modified Scale), cognitive function (Mini Mental State Examination), clinical functional - in those areas activity of daily living and motor examination (Unified Parkinson's Disease Rating Scale - UPDRS) and gait cinematic analysis was performed through Qualisys Motion Capture System®. The intervention protocol consisted of gait training in a period of 4 consecutive weeks, with three weekly sessions, lasting 30 minutes each. The post-intervention assessment occurred the next day after the last training session, which was performed cinematic analysis of gait and the UPDRS. Data analysis was performed using the software Statistical Package for Social Sciences® (SPSS) 17.0. Results: The age of volunteers ranged from 41 to 75 years old (62,26 ± 9,07) and the time of clinical diagnosis of PD between 2 to 9 years (4,56 ± 2,42). There was a reduction regarding the score from motor exam domain (p=0,005), only when training with the addition of a 5% load. As for the space-time variables there was no significant difference between groups (p>0,120); however, the training with addition of 5% load presented the following changes: increase in stride length (p=0,028), in step length (p=0,006), in time balance of the most affected member (p=0,006) and reduction in support time of the referred member (p=0,007). Regarding angular variables significant differences between groups submitted to treadmill gait training without addition load and with 5% of load were observed in angle of the ankle at initial contact (p=0,019), in plantar flexion at toe-off (p=0,003) and in the maximum dorsiflexion in swing (p=0,005). While within groups, there was a reduction in amplitude of motion of the ankle (p=0,048), the only workout on the treadmill. Conclusion: The treadmill gait training with addition of 5% load proved to be a better experimental condition than the others because it provided greater gains in a number of variables (space-time and angular gait) and in the motion function, becoming a therapy capable of effectively improving the progress of individuals with PD

Efeitos agudos do alongamento estático antes e após exercício e as características neuromusculares do membro inferior: estudo controlado, randomizado e cego

Objective: To evaluate the acute effects of static stretching before and after isokinetic exercise, neuromuscular and biomechanical properties of muscles Biceps Femoris (BF) and semitendinosus (ST). Methods: Eighty-nine volunteers of both genders, healthy and physically active, with a mean age of 22.52 ± 2.6 years and mean BMI 23.86 ± 3.2 kg/m² were randomized into 4 groups: Control Group (CG) made only one Protocol Exercise (PE) without performing the stretching, the Experimental Group 1 (EG1) did stretching before PE; EG2 did the stretching after PE and EG3 did stretching before and after PE. The volunteers were evaluated on the following variables: Range of motion (ROM), soreness, dynamometric variables concentric and eccentric, Neuromuscular Latency Time (NLT) and electromyographic. In the data analysis was assigned a significance level of 5%. Results: ADM and TLNM reported significant reduction in CG, but remained unchanged in GE with p<0,05 and p<0,01, respectively. As for the soreness, no differences between the groups. The electromyographic activity of the BF and ST, in the concentric phase, showed a significant decrease in all groups (p<0,01). However, in the eccentric phase, ST revealed reduction in all groups (p <0.01), except for the CG, while the BF remained unchanged in all groups. The PT showed significant reduction in both conditions (concentric and eccentric) for all groups, with no difference between them (p<0,01). Conclusion: The results of this study do not favor the use of static stretching, even of short duration, before physical activity. However, after exercise or at times unrelated to the sport, he should be given with the aim of avoiding muscle shortening

A partir de um conjunto de dados obtidos em pesquisa, o texto deseja salientar uma face pouco examinada pelos estudiosos do espiritismo no Brasil: aquela dos grupos espíritas que cultuam extraterrestres. Examina a narrativa Rebelião de Lúcifer, escrita pelo médium potiguar Jan Val Ellam. Sustenta que esta atualiza noções importantes em relação a narrativas de salvação anteriores construídas pelo espiritismo. Destaca em especial o aprimoramento racial e moral através da reencarnação em distintos corpos humanos e em diferentes planetas. Examina-os a partir das noções de exílio planetário e de evolução racializada. Argumenta que Jan Val Ellam as atualiza através da categoria nativa Povo de Alt’Lam e através de bricolagem com outros campos semânticos, notadamente a ufologia e a fi cção científica

Twitter e ciberativismo: o movimento social da hashtag #ForaMicarla em Natal-RN

The spatial and temporal fluidity conditioned by the technologies of social interaction online have been allowing that collective actions of protest and activism arise every day in cyberspace - the cyber-activism. If before these actions were located in geographical boundaries, today's demands and mobilizations extrapolate the location, connect to the global, and at the same time, return to the regional through digital virtuality. Within this context of the relationship between digital technology and global flow of sociability, emerges in October 2010 the social movement of the hashtag "#ForaMicarla", which means the dissatisfaction of cibernauts from Natal of Twitter with the current management of the municipality of Natal-RN, Micarla de Sousa (Green Party). We can find in the center of this movement and others who appeared in the world at the same time a technological condition of Twitter, with the hashtag "#". Given this scenario, this research seeks to analyze how the relationship of the agents of movement hashtag "ForaMicarla", based on the principle that it was formed in the Twitter network and is maintained on the platform on a daily basis, it can create a new kind of political culture. Thus, this study discusses theoretically the importance of Twitter and movements that emerge on the platform and through it to understand the social and political demands of the contemporary world and this public sphere, which now seems to include cyberspace

Estudos analíticos dos grafoelementos do eletroencefalograma em sono: fusos do sono, ondas agudas do vértex e o gradiente de freqüência e amplitude, como indicadores de comprometimento neurológico na criança

Innumerable studies have focused been reported on the sleep spindles (SS), Sharp Vertex Waves (SVW) and REM, NREM Sleep as indicators interpreting EEG patterns in children. However, Frequency and Amplitud Gradient (FAG) is rarely cited sleep parameter in children,that occurs during NREM Sleep. It was first described by Slater and Torres, in 1979, but has not been routinely evaluated in EEG reports. The aim of this study was to assess the absence of SS, SVW and FAG, as an indication of neurological compromise in children. The sample consisted of 1014 EEGs of children referred to the Clinical Neurophysiology Laboratory, Hospital Universitário de Brasília (HUB), from January 1997 to March 2003, with ages ranging from 3 months to 12 years old, obtained in spontaneous sleep or induced by choral hydrate. The study was transversal and analytical, in which, visual analysis of EEG traces was perfumed individually and independently by two electroencephalographers without prior knowledge of the EEG study or neurological findings. After EEG selection, the investigators analyzed the medical reports in order to define and correlate neurological pattern was classified according to the presence or absence of neurological compromise, as Normal Neurological Pattern (NNP), and Altered Neurological Pattern (ANP) respectively. From the visual analysis of the EEG(s), it was possible to characterize 6 parameters: 1- FAG present (64,1%); 2- FAG absent (35,9%); 3 - normal SS (87,9%); 4 - altered SS s (12,1%); 5 - normal SVW s (95,7%); 6 - altered SVW s (4,3%). The prevalence of well-formed FAG is found in the 3 months to 5 years age group in the children with NNF. FAG was totally absent from the age of 10 years. When comparing the three sleep graphielements, it was observed that SVW and SS were predominant in children with NNF. However, FAG absent was more prevalent in the ANF than in altered SS an SVW. The statistical analysis showed that there is a strong association of FAG absent, with isolated alteration, in ANF patients, in that the prevalence ratio was 6,60. The association becomes stronger when FAG absent + altered SS(s) is considered (RP= 6,68). Chi-square test, corrected by Yates technique, showed a highly significant relation for FAG ρ= 0,00000001, for error X of 5%, or else the 95% confidence interval (ρ<0,05). Thus, the FAG absent were more expressive in ANF patient than altered SS(s) and SVW(s). The association becomes stronger in order to establish a prognostic relation, when the FAG is combined with the SS. The results os this study allow us to affirm that the FAG, when absent at ages ranging from 3 months to 5 years , is an indication of neurological compromise. FAG is an age-dependent EEG parameter and incorporated systematically, in the interpretation criteria of the EEG of children s sleep, not only in the maturational point of view, but also neurological disturbances with encephalic compromise

Juventude universitária nos anos 1980: as práticas culturais do movimento estudantil na UFRN

The 1980s, at UFRN represented a moment of resumption of student struggles. The major goals of the student movement in this period was the fight against the authoritarian regime and for the democracy within and outside the university. In this context, events, activities, artistic and cultural productions were organized in order to make a critical policy for the procedure, trying to establish a dialogue between the university community and the population. Our work has made a research on cultural practices of the student movement in the 1980s. We did an analysis on the process of democratic transition in Brazil, the political participation of youth, their cultural practices in the country, society and politics in the RN, the student movement at UFRN and its cultural practices. We also discussed the concept of culture and cultural practices, but also pointed each of the the main activities and cultural productions organized by students of UFRN in that period. As methodological resource, were used the oral sources, the academic literature on the subject and newspaper pieces, newsletters and advertisement material of the students

Escrever o movimento: o cinema itinerante como reinvenção de uma estética do viver

La tesis parte del presupuesto que el cine ofrece la imensa capacidad de entretejer de forma compleja realidad e imaginación. Con eso sugerimos que tal cual una "escuela de vida", según la definición de Edgar Morin (2003), el cine, por medio de sus producciones y exibiciones, pude ser capaz de operar un movimiento de reinvención de una estética del vivir en el espacio de lo improbable. De ahi surge la pregunta: ¿Cómo un fenómeno artístico, estético e imagético puede realizar tal movimiento? Tomando como referencia el guión de vida del personaje de la vida real José Isaias de Lucena Filho, más conocido por Zezeco, encontramos pistas de esa reinvención. Residente de una pequeña ciudad del interior de la província de Rio Grande do Norte, llamada Ouro Branco, en la década del 1960, se desplazó hacia el centro-sur de Brasil y retornó a su lugar de partida con la idea de trabajar proyectando peliculas. De manera singular y plural, este sujeto asumió el riesgo y la incertidumbre de enfrentar determinismos sociales, climáticos y culturales para proponer nuevas simbolizaciones por medio del cine itinerante. La presencia del séptimo arte en pequeñas ciudades de hábitos rurales marcadas por la miséria, el hambre, la negligéncia, el coronelismo político y los problemas climáticos, alteró escenários, actualizó mitos y proporcionó nuevas interacciones entre los sujetos. Zezeco entró en las cifras del éxodo rural y emigró hacia Rio de Janeiro, pero su éxodo fue cinematográfico, porque le sirvió como base para la inserción de efectos especiales fantásticos y poéticos en guiones de vidas inmersas en lo trivial y lo contingente. Tal cual un cinematógrafo vivo, capturó el escenário cultural efervescente de Rio de Janeiro y lo proyectó en la pequeña ciudad de Ouro Branco y en otras ciudades del interior de las províncias de Rio Grande do Norte y Paraiba. Con ello le atribuyó un nuevo uso a la vida de su lugar de partida y de retorno. Actuó en la ambiguedad, la ambivalencia y la complejidad entre el sapiens e el demens; real e imaginario; prosa y poesia de la vida; razón y pasión; racional y simbólico; lógico y mítico. El alcance de la investigación contempla entrevistas, memória, registros manuscritos y fotografías de colección particular de habitantes de la ciudad de Ouro Branco-RN. Como referenciales teóricos principales, tenemos las obras de Edgar Morin sobre el cine y de otros autores como Giorgio Agamben y Maria da Conceição de Almeida que expanden la comprensión sobre el entreejido de realidad e imaginación, vida e ideas

Liberdade de expressão: amplitude, limites e proteção constitucional no deireito brasileiro.

This dissertation focus, as main objective, to address the issue of fundamental rights and political freedoms of the individuals, guaranteed by the Constitution of 1988, with emphasis of study in the constitutional guarantee of freedom of speech, as well as in national related constitutional law institutions and its derivatives, and the connection with the historical and political affirmation of fundamental human rights and its importance for the construction, maintenance and consolidation of constitutional democracy in the Federative Republic of Brazil. This paper mainly deals with aspects of juspostive nature, focused mainly within its doctrinal aspect, making, for such, references both to the patrian doctrine and the foreign one, without forgetting the necessary jurisprudencial focus and analysis of the positive patrian planning with references to comparative law, in order to describe and analyze the emergence, evolution and dissemination of the institute, both in the major countries of the Western World and along the Brazilian constitutional history.

Movimento de borboletas frugívoras e conectividade funcional em uma paisagem de Mata Atlântica

An organisms movement within and between habitats is an essential trait of life history, one that shapes population dynamics, communities and ecosystems in space and time. Since the ability to perceive and react to specific conditions varies greatly between organisms, different movement patterns are generated. These, in turn, will reflect the way species persist in the original habitat and surrounding patches. This study evaluated patterns of movement of frugivorous butterflies in order to estimate the connectivity of a landscape mosaic in an area of Atlantic Forest. For this purpose, we used the capture-mark-recapture method on butterflies trapped with fermented fruit bait in three distinct habitats. The first represents a typical Atlantic forest fragment, while the other two represent man-made matrix habitats. One contains a coconut plantation and the other a plantation of the exotic Acacia mangium species. Five traps were randomly placed in each landscape unit in areas of 40 x 40m. Using recapture data and relating it to distance between captures and habitat structure, I found that movement frequencies, both within and between landscape units were different for the analyzed species, suggesting that they do not interpret and react to the landscape in the same way. Thus this study was able to measure landscape functional connectivity. For most species, the exchange between forest and coconut plantations occurred with low frequency compared to exchanges between the forest and acacia plantations, which share more structural similarities. This seems to indicate that a matrix that is more similar to patches of native vegetation can shelter species, permit their movement and, consequently, contribute to the landscape connectivity
