Análise da flexibilidade e da postura em jovens atletas praticantes de futebol

there is evidence that sport can trigger the onset of postural patterns specific to each modality, regardless of the geopolitical aspects, social, cultural habits of everyday life and ethnicity. Since changes in flexibility are cited as possible precursors of decreased range of motion, thereby harming the mechanics of the lower limbs and gait. Objetcive: The objective of this study was to analyze changes in posture and flexibility in young soccer players. Methods: were assessed 51 youngsters, aged between 14 and 18 years, soccer players registered in the Municipal Presidente Prudente SP and categories of the base of Gremio of Presidente Prudente. Data were collected from the assessment by the postural software assessment, and flexibility tests the Bench, to jail and later by tests of muscle length to jail earlier proposed by Kendall et al , was also collected anthropometric data were later confronted with the results statistically. The results were organized into spreadsheets for computing, which later could be performed the statistical analysis. Values are expressed by means of central tendency and variability as well as medians and 95% confidence intervals. The comparison for each profile height and BMI was made by means of analysis of variance complemented by Tukey test. Were considered the statistical differences when P <0.05. Results: In the sample studied 64% of the subjects classified as normal posture, the same happened with 70.59% of the athletes for flexibility in relation to the center of gravity of the sample had 100% anterior displacement of the trunk and 86.28% with a deviation of center of gravity to the left, showing a tendency to some postural deviations for the group assessed. Conclusion: from the results we can conclude that there was significant relationship between the postural angle of the right leg and left angle of the pelvis with BMI and also ankle angle...

Equilíbrio, funções executivas e quedas de idosos com demência de Alzheimer: um estudo longitudinal

Falls among older people is a major clinical problem due to its high incidence, with consequent implications for the health and care costs. Elderly patients with dementia of Alzheimer type (AD) are more susceptible to falls due to the impairment of executive functions and gait, with the risk of falls 3 times higher than non-demented elderly. This study used a longitudinal design and aimed to analyze the effects of a regular and systematized physical activity program on the frequency of falls in patients with AD. Additionally, we aimed to correlate the frequency of falls with the executive functions and equilibrium, after and before the physical activity program. The study included 21 patients with clinical diagnosis of AD, divided into two groups: control group (CG), composed of 11 subjects not engaged in any systematized physical activity and training group (TG): 10 seniors who participated in the Cinesioterapia Functional and Cognitive in Elderly with Alzheimer's disease program (PRO-CDA). The physical activity program lasted four months, with weekly frequency of three times, with each session lasting 60 minutes. Were administered the Mini-Mental State Examination (MMSE) to assess cognitive functioning and global score of the Clinical Dementia Rating (CDR) to classify the severity of dementia. For the evaluation of executive functions were used the Clock Drawing Test (TDR) and Frontal Assessment Battery (FAB). In addition, we used the Functional Balance Scale, Berg test (EEFB) and Timed Up-and-Go (TUG) to assess the equilibrium and risk of falls. Falls were recorded by means of a questionnaire, which included the number of falls in the last four months. Analyzing the results, it was observed that TG obtained significant improvements in equilibrium and in executive functions, highlighting the beneficial effects of physical activity in these variables...

Efeito da tarefa dupla na variabilidade do andar livre e adaptativo de pacientes com demência de Alzheimer

O objetivo do estudo foi analisar o efeito da tarefa dupla na variabilidade do andar livre e adaptativo em pacientes com demência de Alzheimer. Foram avaliados 30 indivíduos de ambos os sexos. Os participantes realizaram 5 tentativas para cada condição de andar (livre e adaptativo, com tarefa dupla e sem tarefa dupla), totalizando 20 tentativas.As variáveis espaço-temporais foram coletadas através de um sistema optoeletrônico. Para o andar livre foram considerados os cinco passos centrais da passarela. Para o andar adaptativo foram considerados os três passos anteriores ao obstáculo, o passo de ultrapassagem e o primeiro passo após a ultrapassagem. Os valores do desvio-padrão de cada variável de cada indivíduo nas 5 tentativas para cada condição de andar foram utilizados para calcular a variabilidade dos seguintes parâmetros: comprimento, largura, duração da fase de suporte simples e de duplo suporte, e velocidade de cada passo. Para verificar as diferenças entre as condições experimentais, foram empregadas ANOVAs, com medidas repetidas para a condição experimental. Os resultados indicaram que a tarefa dupla teve pouco efeito na variabilidade do andar livre de pacientes com DA. As variações ocorreram com maior frequência quando a tarefa dupla foi exigida concomitante com o obstáculo, deixando claro que os efeitos da doença influenciam no planejamento da ação. Conclui-se que a tarefa executiva de contagem regressiva não exerceu influência nas variáveis da marcha livre e que o andar adaptativo com contagem apresentou resultados com maior variabilidade, sendo mais desafiador e exigindo maiores ajustes dos pacientes

Modulação da velocidade do andar em indivíduos com doença de Parkinson em estágio leve e moderado

A doença de Parkinson (DP) é uma patologia crônica, degenerativa e progressiva acarretada pela perda de neurônios dopaminérgicos da substância negra (parte compacta), localizada nos núcleos da base. Os comprometimentos na marcha estão entre as principais consequências da DP. Entretanto, pouco se conhece sobre o efeito do estágio da doença na modulação da velocidade do andar. Assim, o objetivo do estudo foi verificar como pacientes em diferentes estágios da DP modulam os parâmetros do andar quando requeridos a andar em máxima velocidade. Os participantes do estudo foram indivíduos com DP idiopática em estágio unilateral (entre 1 e 1,5 na Escala de Hoehn & Yahr) e bilateral (entre 2 e 3 na Escala de Hoehn & Yahr). Inicialmente, os participantes foram submetidos a uma avaliação clínica, realizada por um médico neuropsiquiatra, para verificar o acometimento geral e o estágio da doença. Os dados da avaliação clínica foram utilizados para a distribuição dos participantes entre os dois grupos. Em seguida, os participantes foram convidados a andar sobre uma passarela de 10m de comprimento em duas condições experimentais: Velocidade preferida e velocidade máxima. Somente o grupo bilateral não foi capaz de modular o comprimento da passada na condição de velocidade máxima. Os resultados sugerem que a evolução da DP compromete a capacidade dos pacientes em modular a amplitude de movimentos (comprimento da passada) quando são requeridos a andar em velocidade máxima

Variability in obstacle clearance may (not) indicate cognitive disorders in alzheimer disease

The aim of this study was to investigate obstacle clearance and its variability in individuals with Alzheimer dementia (AD) as well as healthy elderly individuals while they approached and crossed an obstacle in their path. Fifteen people with AD and 15 age-matched/sex-matched healthy individuals (control group) participated in this study. Clinical assessment of both groups was performed by a neuropsychiatrist. Spatial-temporal parameters of 5 trials of unobstructed walking and 5 trials of obstacle crossing during walking (approach and crossing phases) were measured using a 3-dimensional optoelectronic system. The results indicated that individuals with AD showed higher variability in the approach phase for stride length and the horizontal distance from their trailing limb foot to the obstacle. However, their gait variability in the crossing phase was similar to the control group. In addition, the individuals with AD were found to walk slowly and with a short stride length in both conditions. In conclusion, individuals with AD had increased gait variability while approaching an obstacle during walking, indicating a deficit in planning to avoid obstacles that could be related to cognitive disorders. However, gait variability during the crossing phase may not be indicative of cognitive disorders in AD.

Clinical and laboratory description of a series of cases of acute viral myositis

Describe the clinical and laboratory profile, follow-up, and outcome of a series of cases of acute viral myositis. A retrospective analysis of suspected cases under observation in the emergency department was performed, including outpatient follow-up with the recording of respiratory infection and musculoskeletal symptoms, measurement of muscle enzymes, creatine phosphokinase (CPK), lactate dehydrogenase (LDH), transaminases (AST and ALT), blood count, C-reactive protein, and erythrocyte sedimentation rate in the acute phase and during follow-up until normalization. Between 2000 and 2009, 42 suspected cases were identified and 35 (27 boys) were included. The median age was 7 years and the diagnosis was reported in 89% in the first emergency visit. The observed respiratory symptoms were cough (31%), rhinorrhea (23%), and fever (63%), with a mean duration of 4.3 days. Musculoskeletal symptoms were localized pain in the calves (80%), limited ambulation (57%), gait abnormality (40%), and muscle weakness in the lower limbs (71%), with a mean duration of 3.6 days. There was significant increase in CPK enzymes (5507±9180U/L), LDH (827±598U/L), and AST (199±245U/L), with a tendency to leukopenia (4590±1420) leukocytes/mm(3). The complete recovery of laboratory parameters was observed in 30 days (median), and laboratory and clinical recurrence was documented in one case after 10 months. Typical symptoms with increased muscle enzymes after diagnosis of influenza and self-limited course of the disease were the clues to the diagnosis. The increase in muscle enzymes indicate transient myotropic activity related to seasonal influenza, which should be considered, regardless of the viral identification, possibly associated with influenza virus or other respiratory viruses.

Reduced knee flexion is a possible cause of increased loading rates in individuals with patellofemoral pain

Stair ascent is an activity that exacerbates symptoms of individuals with patellofemoral pain. The discomfort associated with this activity usually results in gait modification such as reduced knee flexion in an attempt to reduce pain. Although such compensatory strategy is a logical approach to decrease pain, it also reduces the normal active shock absorption increasing loading rates and may lead to deleterious and degenerative changes of the knee joint. Thus, the aims of this study were (i) to investigate whether there is reduced knee flexion in adults with PFP compared to healthy controls; and (ii) to analyze loading rates in these subjects, during stair climbing. Twenty-nine individuals with patellofemoral pain and twenty-five control individuals (18-30years) participated in this study. Each subject underwent three-dimensional kinematic and kinetic analyses during stair climbing on two separate days. Between-groups analyses of variance were performed to identify differences in peak knee flexion and loading rates. Intraclass correlation coefficient was performed to verify the reliability of the variables. On both days, the patellofemoral pain group demonstrated significantly reduced peak knee flexion and increased loading rates. In addition, the two variables obtained high to very high reliability. Reduced knee flexion during stair climbing as a strategy to avoid anterior knee pain does not seem to be healthy for lower limb mechanical distributions. Repeated loading at higher loading rates may be damaging to lower limb joints.
