A escola postural sob a perspectiva da educação somática : a reformulação de um programa de extensão na ESEF/UFRGS

Esta tese apresenta uma reflexão sobre pedagogias da postura que questiona a valorização de “corpos retos e corretos” presentes nas abordagens tradicionais da postura e propõe uma abordagem alternativa que, evitando modelos ideais de corpo e pretendendo proporcionar soluções viáveis às dificuldades posturais, valoriza o desenvolvimento da percepção cinestésica e o repensar dos contextos vivenciados. Essa reflexão foi formulada a partir de um diálogo com a Antropologia do corpo e da saúde e possibilitou que a autora argumentasse e justificasse a reformulação da Escola Postural da EsEF/UFRGS — de uma perspectiva biomecânica e cinesiológica sobre o corpo, para uma perspectiva da Educação Somática — e que analisasse o processo de implementação dessa reformulação. O estudo foi dividido em três partes: a primeira discute diferentes propostas pedagógicas sobre a postura, apresentando argumentos que justificam o interesse em desenvolver uma abordagem alternativa; a segunda apresenta o programa original de Escola Postural da EsEF/UFRGS e a sua reformulação com base na perspectiva da Educação Somática; a terceira, uma análise das falas dos alunos que participaram desse processo de reformulação e implementação. Foram realizadas, durante os 3 semestres (2002-2003) que durou o referido processo de reformulação e implementação da nova proposta, entrevistas semi-estruturadas (com 50 alunos) e observações-participantes (de 65 alunos), as quais compuseram o material empírico deste estudo. As reflexões tecidas nesta tese explicitam a viabilidade de uma educação alternativa da postura e o interesse de muitos sujeitos por uma abordagem que, deixando de lado a produção/construção de “corpos retos e corretos”, ensina a perceber e a repensar a postura.

Comparação da carga postural dos operadores de duas ilhas de atendimento de uma loja de departamento

O Objetivo deste estudo foi avaliar a carga postural dos operadores de duas ilhas de atendimento de uma rede de lojas de departamento de Porto Alegre, Rio Grande do Sul. A ilha velha exige trabalho de pé e manuseio de peso na operação de ensacolamento de produto e desmagnetização da sacola. A ilha nova foi desenhada para permitir alternância de postura e reduzir o manuseio de peso no ensacolamento, tendo eliminado a operação de desmagnetização da sacola. Com base em observações diretas e indiretas (filmagens gravadas em VHS) e num instrumento desenvolvido para a avaliação das posturas, foi feita análise postural de doze operadores de uma loja. Verificou-se que a ilha nova eliminou os esforços mais importantes que existiam na ilha velha: o esforço estático nos membros inferiores e o movimento de flexão e rotação do tronco associado ao manuseio de sacolas. Algumas operações que ainda geravam risco de desenvolvimento de distúrbios músculo-esqueléticos na ilha nova (rotação e flexão de tronco e flexão e abdução de membros superiores para manipulação de embalagens e colocação de cabides) foram identificados no estudo e serviram de embasamento para melhorias no protótipo final, as quais já foram implantadas e estão, em uma segunda fase do projeto, sendo testadas.

The second study, Current Financing for the Green Economy in Brazil, provides an initial estimate of the financial assets already allocated to the green economy, as well as a methodological proposal for the survey and monitoring of the respective flow of assets. The third and final study looks at two important segments of the Brazilian economy and their process of transition to a greener economy: renewable energy and agriculture.

Avaliação dos efeitos da reeducação postural global (rpg) em pacientes com espondilite anquilosante

The Ankylosing Spondylitis (AS) is a chronic inflammatory disease that primarily affects the axial skeleton, leading to limitation of spine mobility and functional disability. Physical therapy, especially exercise, is an important part in your treatment. The Global Postural Reeducation(GPR),a method that uses stretching based on evaluation of muscular chains, with significant interference in postural changes may be a complementary alternative for the treatment of this disease. The aim was to evaluate the effects of Global Postural Reeducation (GPR) in patients with Ankylosing Spondylitis (AS) and compare GPR with group conventional segmental self-stretching and breathing exercises. This is a controlled interventional study of 38 patients divided into 2 groups: a GPR group (n = 22) and a control group (n = 16). Both groups were treated over four months. With the GPR group patients, positions that stretched the shortened muscle chains were used. With the control group patients, conventional segmental self-stretching and breathing exercises were performed. The variables analyzed were: pain intensity, morning stiffness, spine mobility, chest expansion, functional capacity (Health Assessment Questionnaire - Spondyloarthropathies - HAQ-S), quality of life (Medical Outcome Study Short Form 36 Healthy Survey-SF-36), and disease activity (Bath Ankylosing Spondylitis Disease Activity Index - BASDAI). Statistical analysis was used with a significance level of p < 0.05. There was a statistically significant difference for all the parameters analyzed between pre and post-treatment in both groups. In the inter-group comparison the GPR group showed a statistically significant improvement in morning stiffness (p = 0.01), spine mobility parameters, except finger-floor distance (p = 0.11), in chest expansion (p = 0.02), and in the physical aspect component of the SF-36 (p = 0.00).Finally, we observed that this sample of patients with AS ,treatment with RPG 60 seems to have a better response in some clinical measures, than the conventional self stretching performed in groups. Further studies are needed to further evaluate this therapeutic alternative in the EA

Postural control and functional balance in individuals with diabetic peripheral neuropathy

A Neuropatia diabética periférica (NDP) cursa com redução somatossensitiva que pode levar a alterações no controle postural. O objetivo do estudo foi avaliar o controle postural na postura ereta, em diferentes condições, e o equilíbrio funcional em indivíduos com NDP, correlacionar os resultados obtidos na avaliação do controle postural com os valores do teste do equilíbrio funcional e comparar os resultados obtidos no grupo neuropata com o grupo controle, verificando as possíveis diferenças entre as condições de avaliação em ambos os grupos. Participaram do estudo 13 mulheres com NDP (GN) e 17 mulheres não diabéticas (GC). A avaliação do controle postural foi realizada por cinemetria nas condições: olhos abertos (OA), olhos fechados (OF) e semi tandem (ST). Após processamento no MATLAB, foram geradas as variáveis: amplitude média de oscilação (AMO) na direção ântero-posterior (AP) e médio-lateral (ML); e velocidade média de oscilação (VMO) na direção AP e ML. O equilíbrio funcional foi avaliado pelo Timed Up and Go Test. Houve diferença significante entre os grupos (p<0,005) na AMO-AP OA e OF, AMO-ML of e ST e VMO-ML ST. Houve diferença entre as condições OA e ST (p<0,005) e of e ST (p<0,005) para as variáveis AMO-ML e VMO-ML, com maior prejuízo para o GN, que também apresentou um menor equilíbrio funcional (p=0,001). A instabilidade ML foi correlacionada positivamente com o desequilíbrio funcional. Os resultados nos mostram uma alteração no sistema de controle postural na NDP, o que pode levar estes indivíduos a um maior risco a quedas e prejuízos funcionais.

Desempenho muscular e equilíbriu postural em idosas frágeis residentes na comunidade

Human aging is physiological process causes alterations in several systems of the organism. In the musculoskeletal system, a main change is the decreased muscle strength, that in the lower extremity, compromises the ability to respond quickly with enough strength to prevent falls, causing alterations in postural balance. Currently, many researchers have study the human frailty, defined as a multifactorial syndrome, with excess of vulnerability to stressors, reducing ability in maintaining or regulating homeostasis. Its characteristics are directly related to physical function. Aim: To analyze muscle performance and postural balance in frail and pre-frail elderly women, and to compare them according with the frailty phenotypes criteria proposed by Fried 2001. Method: 39 frail elderly women living in the community, aged 65 years and older, were assessed muscle performance of lower extremity using isokinetic dynamometer and postural balance using Berg s balance scale and computerized baropodometry. Results: There was significant difference in plantar flexor, knee flexor and knee extensor strength, in anteroposterior (AP) oscillation with eyes open and on Berg s scores between groups. A weak correlation was observed between strength and balance. Conclusion: The results suggest that the frail elderly present worse muscle performance in lower extremity and worse postural balance compared to the pre-frail elderly. There were correlations between muscle performance and balance impairments in these elderly, but several variables are also involved in maintaining postural balance

Dental students' knowledge of ergonomic postural requirements and their application during clinical care

Aim:To examine how much final-year undergraduate dental students know about postural dental ergonomic requirements, and how well they apply these requirements clinically.Background:Dentists are vulnerable to diverse mechanical (e.g. postural) and non-mechanical occupational risks.Materials and Methods:Eight postural requirements found in normalising documents were identified, reproduced, photographed, and analysed to develop a test of visual perception (TVP). Photographs of the 69 participating students were taken during their clinical care to ascertain ergonomics compliance, after which the students were administered the TVP. Pearson's test was used to correlate the level of knowledge (TVP) and its clinical application (photographic analysis) among the 552 observations made for each test (total of 1104 observations).Results:65.7% of the TVP questions were answered correctly and 35% of the photographic cases were in compliance with ergonomic requirements (+ 0.67, P < 0.0001).Conclusion:The knowledge of ergonomics postural requirements and their clinical application among the dental students surveyed were not satisfactory. The reasons for the learning difficulties encountered by the students should be identified to improve the learning process. The didactic use of digital images in this study may help in this endeavour.

Postural control and automaticity in dyslexic children: The relationship between visual information and body sway

Difficulty with literacy acquisition is only one of the symptoms of developmental dyslexia. Dyslexic children also show poor motor coordination and postural control. Those problems could be associated with automaticity, i.e., difficulty in performing a task without dispending a fair amount of conscious efforts. If this is the case, dyslexic children would show difficulties in using "unperceived" sensory cues to control body sway. Therefore, the aim of the study was to examine postural control performance and the coupling between visual information and body sway in dyslexic children. Ten dyslexic children and 10 non-dyslexic children stood upright inside a moving room that remained stationary or oscillated back and forward at frequencies of 0.2 or 0.5 Hz. Body sway magnitude and the relationship between the room's movement and body sway were examined. The results indicated that dyslexic children oscillated more than non-dyslexic children in both stationary and oscillating conditions. Visual manipulation induced body sway in all children but the coupling between visual information and body sway was weaker and more variable in dyslexic children. Based upon these results, we can suggest that dyslexic children use visual information to postural control with the same underlying processes as non-dyslexic children; however, dyslexic children show poorer performance and more variability while relating visual information and motor action even in a task that does not require an active cognitive and conscious motor involvement, which may be a further evidence of automaticity problem.

Postural control in Down syndrome: the use of somatosensory and visual information to attenuate body sway

The purpose of this study was to examine the effects of visual and somatosensory information on body sway in individuals with Down syndrome (DS). Nine adults with DS (19-29 years old) and nine control subjects (CS) (19-29 years old) stood in the upright stance in four experimental conditions: no vision and no touch; vision and no touch; no vision and touch; and vision and touch. In the vision condition, participants looked at a target placed in front of them; in the no vision condition, participants wore a black cotton mask. In the touch condition, participants touched a stationary surface with their right index finger; in the no touch condition, participants kept their arms hanging alongside their bodies. A force plate was used to estimate center of pressure excursion for both anterior-posterior and medial-lateral directions. MANOVA revealed that both the individuals with DS and the control subjects used vision and touch to reduce overall body sway, although individuals with DS still oscillated more than did the CS. These results indicate that adults with DS are able to use sensory information to reduce body sway, and they demonstrate that there is no difference in sensory integration between the individuals with DS and the CS.
