Visto que a prática de exercício físico é um dos fatores que pode gerar modificações positivas nessas variáveis, o objetivo do presente estudo foi verificar os efeitos de um programa de treinamento concorrente (TC) incluindo exercícios aeróbios e de força em uma mesma sessão e de força separadamente (TF), nas variáveis de força e equilíbrio de mulheres idosas. Trinta e duas idosas sendo 21 fisicamente ativas e 11 fisicamente inativas foram divididas aleatoriamente em três grupos: TF (treinamento de força n=11), TC (treinamento concorrente n=10), GC (grupo controle n=11), em um programa com 10 semanas de intervenção. O protocolo de treinamento do grupo TF originou ganhos significativos de potência aeróbia (p<0,001), força estática (lombar p<0,001 e membros inferiores p<0,001) e dinâmica (p<0,001) e equilíbrio dinâmico (p<0,001), porém não foi suficiente para observar melhoras no equilíbrio estático. O grupo que realizou o treinamento concorrente obteve ganhos significativos na potência aeróbia (p=0,002), força dinâmica (p<0,001) e estática (apenas de membros inferiores p=0,009) além de equilíbrio estático (p= 0,002) e dinâmico (p<0,001). Com exceção da variável equilíbrio dinâmico no grupo que realizou treinamento de força e do equilíbrio estático nos dois grupos, houve melhora significativa em todas as outras variáveis analisadas em relação ao grupo que permaneceu inativo. Não foi observada diferença significativa entre os dois grupos intervenção. Os resultados deste estudo sugerem que, em idosas, o TC foi mais eficiente na melhoria do equilíbrio, pois alterou equilíbrio estático e dinâmico e o TF foi melhor para ganho de força estática (lombar e membros inferiores) e dinâmica. / Aging leads to muscular strength and balance decrease that together result in higher chance of falls and fractures among the elderly. Because physical exercise can contribute positively to improve such capacities, the aim of the present study was to evaluate the effects of a training program including concurrent training (CT) and strength training (ST) exercises alone on potential benefits in balance and strength of elderly women. Thirty two elderly women (21 physically active and 11 inactive) were randomly assigned to one of the following groups: concurrent training (CT - n=10) and strength training (ST - n=11) and control group (CG - n=11) during a 10-week intervention program. The ST protocol resulted in aerobic improvements (p<0.001), static (lumbar and lower limbs; p<0.001) and dynamic strength (p<0.001) besides an improvement in dynamic balance (p<0.001), however improvements were not observed in static balance. In the CT group we observed improvements in aerobic conditioning (p=0.002) dynamic (p<0.001) and static strength (only lower limbs; p=0.009) and static (p=0.002) and dynamic (p<0.001) balance. Except for the dynamic balance in the ST group and static balance for both groups, all capacities were improved compared to control group. We could not observe differences between the intervention groups. Our results suggest that in elderly women CT was better to improve balance, as it resulted in static and dynamic improvements, while ST presented better results for static (lumbar and lower limbs) and dynamic strength.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Obesity is a health problem worldwide and projections of the World Health Organizations provide significant improves in rates for the coming years. Together with health problems related to obesity there are significant evidence that postural balance is also affected, which can lead limitations on activities of daily living. Purpose: Dissertation was divided in two research papers, each with different purposes: 1) To verify the influence of obesity on postural balance; and 2) To verify the influence of a treatment for weight reducing on obese individual s postural balance. Material and Method: The first paper s sample were composed by 48 overweight and obese individuals with mean age of 49,04 ± 8,59 years, mean height of 163,28 ± 5,58 cm and mean weight of 92,97 ± 16,49 kg. Fifteen women of that sample performed treatment for weight loss, composed by aerobic and anaerobic exercises three times a week and dietary guidelines once a week, during 12 weeks. They composed the second paper s sample and had mean age of 48,93 ± 7,04 years, mean height of 161,63 ± 4,57 cm and mean weight of 85,51 ± 10,58 kg. Were collected anthropometric data related to obesity level, like body mass, height, body mass index and waist circumference, and data related to postural balance with a force platform AMTI (Advanced Mechanical Technologies, Inc.) and foam-laser dynamic posturography, before and after proposed training. Results: Study results showed that the anthropometric variables did not change and only one postural balance variable significantly improved after treatment in a situation with closed eyes. After division in groups according body mass index (overweight group = GSP; obesity I group = GO I; obesity II group = GO II; obesity III group = GO III) was found better postural balance for GO III and worse postural balance for GO II. Was found significant moderate associations between postural balance values and obesity indicators, when removed GO III of analysis, denoting better postural balance for individuals with smaller obesity levels. Conclusions: Training performed improved only one of analyzed balance variables and individuals with higher body mass index have better postural balance than other individuals. There are a negative linear association between postural balance and obesity in individuals that composed groups GSP, GO I and GO II. / A obesidade é um problema de saúde em escala mundial e projeções da Organização Mundial da Saúde preveem aumentos significativos dos índices para os próximos anos. Juntamente com problemas de saúde relacionados à obesidade existem indícios significativos que o equilíbrio postural também é afetado, o que pode trazer limitações para atividades de vida diárias. Objetivo: A dissertação foi dividida em dois artigos de pesquisa, cada um com objetivos diferentes: 1) Verificar a influência da obesidade sobre o equilíbrio postural; e 2) Verificar a influência de um tratamento para redução de peso no equilíbrio postural de indivíduos obesos. Materiais e método: O grupo de estudo do primeiro artigo foi composto por 48 indivíduos com sobrepeso e obesos com idade média de 49,04 ± 8,59 anos, estatura corporal média de 163,28 ± 5,58 cm e massa corporal média de 92,97 ± 16,49 kg. Quinze mulheres deste grupo realizaram um tratamento para redução de peso, composto por exercícios aeróbicos e anaeróbicos três vezes na semana e orientações nutricionais por uma vez semanal, durante 12 semanas. Estas compuseram o grupo de estudo do segundo artigo e tinham idade média de 48,93 ± 7,04 anos, estatura corporal média de 161,63 ± 4,57 cm e massa corporal média de 85,51 ± 10,58 kg. Foram coletados dados antropométricos relacionados ao nível de obesidade, como massa corporal, estatura, índice de massa corporal e circunferência da cintura, e dados referentes ao equilíbrio postural com uma plataforma de força AMTI (Advanced Mechanical Technologies, Inc.) e posturografia dinâmica foam-laser, antes e depois do tratamento proposto. Resultados: Os resultados do estudo revelaram que as variáveis antropométricas não sofreram alterações e apenas uma variável de equilíbrio postural apresentou melhora significativa após o tratamento, em uma situação com olhos fechados. Após a divisão em grupos de acordo com o índice de massa corporal (grupo com sobrepeso = GSP; grupo obesidade I = GO I; grupo obesidade II = GO II; grupo obesidade III = GO III) foi encontrado melhor equilíbrio postural para GO III e pior equilíbrio postural para GO II. Foram encontradas associações moderadas e significativas entre valores de equilíbrio postural e indicadores de obesidade, quando retirada da análise o GO III, denotando melhor equilíbrio postural para indivíduos com menores níveis de obesidade. Conclusões: O tratamento realizado melhorou apenas uma das variáveis de equilíbrio avaliadas e indivíduos com maior índice de massa corporal têm melhor equilíbrio postural que os demais indivíduos. Existe uma associação linear negativa entre equilíbrio e obesidade entre indivíduos que compuseram os grupos GSP, GO I e GO II.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / In the presence of nasal obstruction, nasal patency may be reduced, and nasal breathing is replaced by mouth breathing (MB). Orofacial, and otorhinolaringologic changes are present in this breathing mode, as well as head posture misalignment, as a compensatory mechanism for the nasal airflow impairment. Some characteristics are typically found, but MB diagnosis is still controversial among multidisciplinary assessments. This study was conduct to identify variables associated with mouth breathing diagnosis in children, based on multidisciplinary domains, including anamnesis, speech therapy, otorhinolaryngologic, occlusal and physiotherapeutic assessments. It also aimed to compare nasal patency and otorhinolaryngologic-orofacial features and craniocervical posture in children. Six-12 year-old children, both sexes underwent muldisciplinary evaluation constituted by: anamnesis; speech therapy evaluation, according to MBGR protocol; clinical and endoscopic otorhinolaryngologic (OTRL) examination; occlusal and physical therapy assessments (nasal patency and body posture). Nasal patency was measured, by means of Peak Nasal Inspiratory Flow absolute (PNIF) values and Nasal Obstruction Symptom Evaluation (NOSE) scale. Craniocervical posture was evaluated with biophotogrametric measures (software SAPO, v.0.68), such as: Cervical Distance (CD); Head Horizontal Alignment (HHA), Flexion-Extension Head Position (FE) and Lumbar Distance (LD). Mann-Whitney, Kruskal-Wallis, Spearman Correlation Coefficient and Multiple Logistic Regression were used for data analysis. One hundred thirty three children took part in the study. Significant lower values of PNIF and %PNIF in children with restless sleep (p=0.006 and p=0.002), nasal obstruction report (p=0.027 and p=0.023) and runny nose (p=0.004 and p=0.012), unsystematic lip closure during mastication (p=0.040 and 0.026), masticatory speed reduced (p=0.006 and p= 0.008) and altered solid food swallowing (p=0.006 and p=0.001) were found. Significant lower PNIF was found in children with pale inferior turbinate (p=0.040). PNIF and %PNIF was significantly higher in children with mild everted lip (p=0.008 and p=0.000). PNIF was significantly higher in children with tongue width increased (p=0.027) and lower in children with hard palate width reduced (p=0.037). PNIF was significantly lower in children with altered speech (p=0.004). FE was significantly higher in children with nasal patency decreased (p=0.023). Negative and weak correlation between FE and %PNIF (r=-0.266; p=0.002) and positive and weak correlation between CD and PNIF (r=0.209; p=0.016) were found. NOSE scores were negatively correlated with PNIF (r= -0.179; p=0.039). It was found association of MB diagnosis in each professional domain with: nasal obstruction report (OR =5.55), time of pacifier sucking (OR=1.25), convex facial type (OR=3.78), obtuse nasal angle (OR=4.30), half-open or open lip posture (OR=4.13), tongue positioned on the mouth floor (OR=5.88), hard palate width reduced (OR=2.99), unexpected contraction of orbicularis and mentalis muscles during mastication (OR= 2.97), obstructive pharyngeal tonsills (OR=8.37), Angle Class II malocclusion (OR= 10.85) and regular gingival maintenance (OR=2.89). Nasal patency was lower in children with restless sleep, rhinitis signs and symptoms, hard palate width reduced and with changes in mastication, deglutition and speech functions. Children with decreased nasal patency presented greater head extension and, this postural deviation is prone to increase as nasal airflow decreases, indicating the relationship between craniocervical posture and nasal patency. Nasal obstruction report, time of pacifier sucking, convex facial type, obtuse nasal angle, half-open or open lip posture, tongue positioned on the mouth floor, hard palate width reduced, unexpected contraction during mastication, obstructive pharyngeal tonsils, Angle Class II malocclusion and regular gingival maintenance were associated with MB diagnosis / Na presença de uma obstrução nasal, a permeabilidade pode estar reduzida e a respiração nasal é substituída pela respiração oral (RO). Alterações orofaciais e otorrinolaringológicas são associadas a essa condição, bem como alterações na postura da cabeça, como mecanismo compensatório a redução do fluxo nasal. Algumas características são tipicamente associadas a RO, mas seu diagnóstico ainda permanece controverso. Este estudo foi conduzido para identificar variáveis associadas com o diagnóstico de respiração oral em crianças, baseado nos domínios multidisciplinares. Também se propôs a comparar a permeabilidade nasal e as características orofaciais, fonoaudiológicas e postura craniocervical em crianças. Um total de 133 crianças de seis a 12 anos de idade, de ambos os sexos, submeteram-se avaliação multidisciplinar constituída de: anamnese; avaliação fonoaudiológica, de acordo com o protocolo MBGR; exame OTRL clínico e endoscópico; avaliações oclusal e fisioterapêutica (permeabilidade nasal e postura corporal). A permeabilidade nasal foi medida por meio do Pico de Fluxo Inspiratório Nasal (PFIN) e valores da escala Nasal Obstruction Symptom Evaluation (NOSE). A postura corporal foi avaliada com medidas biofotogramétricas (Software SAPO, v.0.68) como: Distância Cervical (DC); Alinhamento Horizontal da Cabeça (AHC); Ângulo de Flexo-Extensão da Cabeça (FE) e Distância Lombar (DL). Para a análise dos dados foram utilizados os testes U de Mann-Whitney, Kruskal-Wallis, Correlação de Spearmann e Regressão Logística Múltipla. PFIN e %PFIN foram menores nas crianças com sono agitado (p=0,006 e p=0,002), relato de obstrução nasal (p=0,027 e p=0,023), rinorreia (p=0,004 e p=0,012), fechamento labial assistemático na mastigação (p=0,040 e p=0,026), velocidade mastigatória reduzida (p=0,006 e p= 0,008), com alteração na deglutição de sólidos (p=0,006 e p=0,001) e somente PFIN naquelas com largura de palato reduzida (p=0,037) e alteração da fala (p=0,004). Foram encontrados valores menores de PFIN nas crianças com palidez das conchas nasais inferiores (p=0,040). PFIN e %PFIN foram maiores nas crianças com lábio levemente evertido (p=0,008 e p=0,000) e somente o PFIN naquelas com largura aumentada da língua (p=0,027). FE foi maior nas crianças com permeabilidade nasal diminuída (p=0,023). Foi encontrada correlação negativa e fraca entre FE e %PFIN (r=-0,266; p=0,002) e positiva e fraca entre DC e PFIN (r=0,209; p=0,016). Os escores da escala NOSE foram negativamente correlacionados com PFIN (r= -0,179; p=0,039). Foi observada associação do diagnóstico de respiração com: relato de obstrução nasal (OR =5,55), tempo de uso de chupeta (OR=1,25), tipo facial convexo (OR=3,78), ângulo nasolabial obtuso (OR=4,30), postura de lábios entreabertos ou abertos (OR=4,13), postura de língua no assoalho da boca (OR=5,88), largura do palato duro reduzida (OR=2,99), contrações não esperadas dos músculos orbiculares e mentual durante a mastigação (OR= 2,97), tonsilas faríngeas obstrutivas (OR=8,37), má oclusão classe II de Angle (OR= 10,85) e conservação gengival regular (OR=2,89). A permeabilidade nasal foi menor em crianças com sono agitado, sinais e sintomas de rinite, largura reduzida do palato duro e alterações nas funções de mastigação, deglutição e fala. Crianças com permeabilidade nasal reduzida apresentaram maior extensão da cabeça e esta alteração postural tende a aumentar à medida que o fluxo nasal diminui, indicando uma relação entre a postura craniocervical e permeabilidade nasal. Foram associadas com a RO as variáveis: relato de obstrução nasal; tempo de uso de chupeta; tipo facial convexo; ângulo nasolabial obtuso; postura de lábios entreabertos ou abertos; postura de língua no assoalho da boca; largura reduzida do palato duro; contrações não esperadas na mastigação; tonsilas faríngeas obstrutivas, má oclusão classe II de Angle e conservação gengival regular.

The aim of the thesis was to investigate the importance of physical function for survival in very old people, and furthermore, whether physical exercise could influence physical function, cognitive function, and dependence in activities of daily living (ADLs) in older people with dementia living in nursing homes. The world’s population is ageing. Given the age-related increase in chronic disease such as dementia   and compounded by physical inactivity, the prevalence in need for assistance and are in daily activities in older people is expected to increase in the near future. Gait speed, a measure of physical function, has been shown to be associated with health and survival. However, studies of the  oldest  people  in  the  population,  including  those  dependent  in ADLs,  living  in  nursing  homes  and  with  dementia,  are  few.  Moreover,  in people  with  dementia  physical  exercise  may  improve  physical and  cognitive function and  reduce  dependence  in  ADLs.  Further large studies with high methodological quality and with designs incorporating attention control groups are needed in this population. In addition, no study has compared exercise effects between dementia types. The association between gait speed and survival was investigated in a population based cohort study of 772 people aged 85 years and over. Usual gait speed was assessed over 2.4 metres and mortality followed for five years. Cox proportional hazard regression models adjusted for potential confounders were used in analyses. Effects of physical exercise in people with dementia were investigated in a randomised controlled trial that included 186 participants with various dementia types living in nursing homes. Participants were allocated to the High-Intensity Functional Exercise  (HIFE) program or a seated control activity, which both lasted 45 minutes and held five times  fortnightly for four months. Dependence in ADLs was assessed with Functional Independence Measure and Barthel ADL Index, and balance with Berg Balance Scale. Usual gait speed was evaluated over 4.0 metres in two tests; first using habitual walking aid if any, and thereafter without walking aid and with minimum living support. Global cognitive function was assessed using the Mini-Mental State Examination, the Alzheimer’s Disease Assessment Scale-Cognitive subscale, and   executive function using Verbal fluency. Blinded testers performed assessments at baseline, four (directly after intervention completion) and seven months. Analyses used linear mixed models in agreement with the intention-to-treat principle. Gait speed was found to be an independent predictor of five-year all-cause mortality, where inability to complete the gait test or a gait speed below 0.5 iv meters per second (m/s) was associated with higher mortality risk. In analyses of exercise effects on ADLs there was no difference between groups in the complete sample. Interaction analyses showed a difference in exercise effect according to dementia type at seven months. Positive between-group exercise effects were found for dependence   in ADLs in participants with non-Alzheimer’s type of dementia (non-AD) at four and seven months. In balance, a difference between groups was found at four but not at seven months in the complete  sample, and interaction analyses indicated a difference in effect according to dementia type at four and seven months. Positive between-group exercise effects were found in participants with non-AD.  No difference between groups in gait speed was found in the complete sample, where the majority habitually walked with a walking aid. In interaction analyses exercise effects differed according to walking aid use. Positive between-group exercise effects in gait speed were found in participants that walked unsupported at four and seven months. No difference between groups in cognitive function was found in the complete sample. The effects of exercise on gait speed and cognitive function did not differ according to sex, cognitive level, or dementia type. In conclusion, among people aged 85 or older, including those dependent in ADLs and with dementia, gait speed seems to be a useful clinical indicator of health status. Inability to complete the gait test or a gait speed below 0.5 m/s appears to be associated with higher five-year mortality risk. In older people with mild to moderate dementia living in nursing homes, a four-month high-intensity functional exercise program appeared to attenuate loss of dependence in ADLs and improve balance, albeit only in participants with non-AD type of dementia. Further studies are needed to validate this result. Furthermore, exercise had positive effects on gait speed when tested unsupported, in contrast to when walking aids or minimum support were used. The result implies that the use of walking aids in the gait speed test may conceal exercise effects. The exercise program had no superior effects on global cognition or executive function when compared with an attention control activity. This thesis suggests that, in older people with dementia, exercise effects on physical function rather than cognitive function may explain effects on dependence in ADLs.

Introduction. The pain is an important symptom that could be related to alteration of body balance in patients who has osteoarthritis and total knee arthroplasty (TKA). Objective. To analyze the intensity of pain, functionality, muscle strength, static and dynamic balance in patients submitted to TKA and to compare with healthy control. Methods. There were 40 subjects, 20 of them were evaluated in three phases: (1) pre-operatory, (2) 6 months after TKA and (3) 12 months after TKA and 20 others healthy people evaluated in one only moment. The evaluation of pain and functionality were done with Numeric Pain Scale and Western Ontario and McMaster Universities Arthritis Index, respectively. The static body balance was evaluated by stabilometry measuring the oscillating area of the center of pressure oscillating, and average speed of the center of pressure oscillating (AS of CPO). The dynamic balance was assessed through the Star Excursion Balance Test (SEBT). And the strength of the muscles of lower members was measured by a manual dynamometer. Results. The intensity of knee pain of those one submitted to TKA was significantly major in preoperative phase (4,05 ±0,84) when related to six (1,95 ± 0,62; p < 0,0001) and twelve months (1,9 ± 0,64; p < 0,007) after surgery. It was observed significant increase of WOMAC score in operated member at six (26,43 ± 5,508) and twelve months (31,48 ± 3,920) after surgery when compared to preoperative period (52,33 ± 3,98) (p<0,01). In intragroup comparisons in AP direction, the AS of CPO increased significantly, in TKA group, after six months (2,90 mm/s ± 0,36) and after twelve months (2,30 mm/s ± 0,31) when compared to preoperative (1,98 mm/s ± 0,16) (p< 0,05). There was no significant difference in area of CPO in intragroup (p=0,3280) and intergroups (p=0,2236) comparisons. The dynamic balance in intragroup comparisons increased significantly in six months (p=0,001) and twelve months (p<0,01) when compared to preoperative. There was significantly increased of hip and knee muscles in operated patients six and twelve months after surgery comparing to preoperative (p<0,05). When comparing healthy control group to TKA group it was observed a lower pain intensity, better functionality, major muscle strength and static and dynamic balance in control group than preoperative, six and twelve months after surgery (p<0,001). Conclusion. The intensity of pain influence in a negative way the functionality, muscle strength, static and dynamic balance in patients with severe osteoarthritis and TKA related to healthy control. / Introdução. A dor é um sintoma pertinente que pode estar relacionado à alteração do equilíbrio corporal em pacientes portadores de osteoartrose e Artroplastia Total do Joelho (ATJ). Objetivo. Analisar a intensidade da dor, funcionalidade, força muscular, equilíbrio corporal em pacientes submetidos à artroplastia total do joelho (ATJ) e comparar com controles saudáveis. Casuística e Métodos.Participaram do estudo 40 sujeitos, sendo 20 avaliados em três fases: (1) pré-operatório, (2) 6 meses após ATJ e (3) 12 meses após ATJ e 20 sujeitos saudáveis avaliados em um único momento. A avaliação da dor e funcionalidade foi realizada através da Escala Numérica de Dor (NRS) e do Western Ontario and McMaster Universities Arthritis Index (WOMAC), respectivamente. O equilíbrio corporal estático foi avaliado por meio de estabilometria, mensurando-se área de oscilação do centro de oscilação de pressão (área do COP) e velocidade média do centro de oscilação de pressão (VM do COP).O equilíbrio dinâmico foi avaliado através do Star Excursion Balance Test (SEBT). E a força dos músculos dos membros inferiores foi mensurada através de um dinamômetro manual. Resultados.A intensidade da dor no joelho dos sujeitos submetidos a ATJ foi significativamente maior na fase pré-operatória (4,05 ± 0,84) em relação às medidas realizadas seis (1,95 ± 0,62 ; p < 0,0001) e 12 meses (1,9 ± 0,64; p<0,007) após a cirurgia. Observou-se aumento significativo do escore do WOMAC do membro operado aos 6 (26,43 ± 5,508) e 12 meses (31,48 ± 3,920) após a cirurgia quando comparado ao período pré-operatório (52,33 ± 3,89) (p<0,01). Nas comparações intragrupos na direção AP, a VM do COP aumentou significativamente, no grupo ATJ, no momento de 6M (2,90 mm/s ± 0,36) e 12M (2,30 mm/s ± 0,31) quando comparada ao pré-operatório (1,98 mm/s ± 0,16) (p < 0,05). Não houve diferença significativa em relação à área do COP nas comparações intra (p=0,3280) e intergrupos (p=0,2236). O equilíbrio dinâmico nas comparações intragrupos aumentou de forma significativa em 6M (p= 0,001) e 12M (p < 0,01) quando comparado ao pré-operatório.Houve aumento significativo da força dos músculos do quadril e joelho nos pacientes operados seis e 12 meses após a cirurgia em comparação ao período pré-operatório (P< 0,05). Ao comparar os controles saudáveis com o grupo ATJ observou uma menor intensidade dolorosa,melhor funcionalidade, maior força muscular, equilíbrio estático e dinâmico do grupo controle em relação aos períodos pré-operatório, 6M e 12M do grupo ATJ (p < 0,001). Conclusão.A intensidade da dor influência de forma negativa na funcionalidade, força muscular, no equilíbrio estático e dinâmico em pacientes portadores de osteoartrose severa e ATJ em relação a controles saudáveis.

INTRODUÇÃO: Estudos com mulheres na faixa dos 50 anos justificam-se porque nesta etapa da vida os declínios fisiológicos são bastante evidentes e relacionados ao climatério e período pós-menopausa. Apesar de viverem mais do que os homens, adoecem mais frequentemente e registram índices mais baixos de saúde percebida do que eles. Melhoras funcionais foram evidenciadas com exercícios na água, todavia são raros os estudos que utilizam a caminhada em imersão como método exclusivo ou principal recurso de intervenção para promoção de saúde. OBJETIVO: Avaliar os efeitos de um programa de 12 meses de caminhada em imersão em mulheres quinquagenárias saudáveis. MÉTODOS: Participaram 59 mulheres em grupos de 10 a 12 participantes que configuraram um único grupo caracterizando-se como um estudo quase-experimental. A intervenção foi realizada 2 vezes por semana em sessões de 30 minutos, por um ano, em piscina aquecida em aproximadamente 310. O programa foi dividido em 4 etapas de 3 meses cada, com evolução crescente na dificuldade dos exercícios. Foram realizadas 5 avaliações: inicial (t0), após 3 meses (t1), 6 meses (t2), 9 meses (t3) e no final do programa - 12 meses (t4). Para a avaliação subjetiva sobre o estado de saúde, mobilidade e humor, foi utilizada uma escala mista de zero a dez. Um breve relato sobre os principais efeitos do programa, com base em questão aberta, também foi analisado. Para a avaliação da força isométrica dos músculos flexores e extensores do quadril e do tornozelo utilizou-se um dinamômetro portátil e para a avaliação da flexibilidade foi utilizado o teste de sentar e alcançar. Para avaliação do equilíbrio foram utilizados os testes de apoio unipodal com olhos abertos (TAU-OA) e fechados (TAU-OF) e o teste \"timed up and go\" (TUG). RESULTADOS: Os resultados observados entre a avaliação inicial e final (t0-t4) do programa mostraram que houve melhora de 16,13% na percepção de saúde (p < 0,001), de 22,15% na mobilidade (p < 0,001) e de 9,69% no humor (p=0,003). Na análise de conteúdo, 49,4% das falas relacionaram-se com a melhora da saúde; 22,9% com a autoestima e satisfação e 19,3% foram relacionadas à capacidade física. A força dos extensores do quadril melhorou 27,67% (p < 0,001), dos flexores do quadril 48,81% (p < 0,001), dos flexores plantares 32,59% (p < 0,001) e dos dorsiflexores 40,75% (p < 0,001). A melhora observada na flexibilidade foi de 54,55% (p < 0,001). O equilíbrio estático avaliado pelo TAU-OA melhorou 35,51% e pelo TAU-OF 261,96% ambos com p < 0,001. Houve melhora de 31,78% no equilíbrio dinâmico (p < 0,001); O equilíbrio, tanto estático como dinâmico e a flexibilidade tiveram melhora em todas as etapas. CONCLUSÃO: O estudo mostrou que esta forma de atividade, realizada em grupos com programa de longa duração, porém de fácil replicação, em 4 etapas progressivas melhorou o estado de saúde, a mobilidade e o estado de humor; a força dos músculos do quadril e do tornozelo, a flexibilidade, bem como o equilíbrio estático e dinâmico das mulheres participantes. Com isto ressaltamos a relevância de políticas públicas que favoreçam e incentivem a prática dos exercícios físicos prazerosos visando um envelhecimento natural e com autonomia funcional / INTRODUCTION: Studies with 50 year-old women are justified because in this stage of life physiological declines are quite evident and related to climacteric and postmenopausal period. Although women live longer than men they fall sick more often and register lower perceived health indices than men do. Functional improvements were observed with immersion exercises, however, studies that use immersion walk as the only method or main intervention resource to promote health are rare. OBJECTIVE: To evaluate the effects of a 12-month immersion walk program in healthy 50 year-old women. METHOD: 59 women participated in groups of 10 to 12 participants which constituted a unique group thus characterized as a quasi-experimental study. The intervention was conducted twice a week, in 30 minute-sessions, for a year, in a pool heated at approximately 31ºC. The program was divided into 4 phases of 3 months each, with increasing evolution in exercise difficulty. 5 evaluations were carried out: initially (t0), after 3 months (t1), 6 months (t2), 9 months (t3) and at the end of the program, 12 months (t4). For the subjective assessment of the health status, mobility and mood, a mixed scale from zero to ten was used. A brief report of the main effects of the program, based on an open question, was also analysed. To evaluate the isometric strength of the flexion and extension muscles of the hip and ankle, a portable dynamometer was used and to evaluate flexibility the sit and reach test was used. To evaluate balance the one-legged stance-open eyes (OLS-OE), the one-legged stance-closed eyes (OLS-CE), and the timed up and go (TUG) tests were used. RESULTS: The results observed between the initial and final evaluation of the program (t0-t4) showed 16.13% improvement in the perception of health (p < 0,001), 22.15% in mobility (p < 0,001) and 9.69% in mood (p= 0,003). In the content analysis, 49.4% of speeches were related to health improvement; 22.9% to self-esteem and satisfaction and 19.3% were related to physical capacity. The strength of hip extensors improved 27.67% (p < 0,001), hip flexors 48.81% (p < 0,001), plantar flexors 32.59% (p < 0,001), and dorsiflexors 40.75% (p < 0,001). Improvement observed in flexibility was 54.55% (p < 0,001). Static balance assessed by OLS-OE improved 35.51% and by OLS-CE 261.96%, both with (p < 0,001). There was a 31.78% improvement in dynamic balance (p < 0,001). Both static and dynamic balance as well as flexibility improved in all phases. CONCLUSION: The study showed that this form of activity, developed in groups with a long-term program, but easily replicated, in 4 progressive stages has improved health status, mobility and mood; hip and ankle muscle strength flexibility, as well as static and dynamic balance of participating women. Thus, we emphasize the relevance of public policies that favour and encourage the practice of pleasurable physical exercises, aiming at a natural aging process with functional autonomy

No / Epidemiologic research has shown that multifocal spectacle wearers (bifocal and progressive addition lenses [PALs]) are more than twice as likely to fall than are nonmultifocal spectacle wearers, with this risk further increasing when negotiating stairs. The present study investigated whether step and stair descent safety is improved by using single-vision distance lenses. METHODS: From a stationary standing position on top of a block, 20 long-term multifocal wearers stepped down (from different block heights) onto a lower level wearing bifocal, progressive addition, or single-vision distance lenses. RESULTS: Use of single-vision distance spectacles led to an increased single-limb support time, a reduced ankle and knee angle and vertical center-of-mass velocity at contact with the lower level, and a reduced ankle angular velocity and vertical center-of-mass velocity during initial landing (P < 0.03). These findings indicate that landing occurred in a more controlled manner when the subjects wore single-vision distance spectacles, rather than tending to "drop" onto the lower level as occurred when wearing bifocals or PALs. CONCLUSIONS: Use of single-vision distance spectacles led to improvements in landing control, consistent with individuals' being more certain regarding the precise height of the lower floor level. This enhanced control was attributed to having a view of the foot, step edge, and immediate floor area that was not blurred, magnified, or doubled and that did not suffer from image jump or peripheral distortions. These findings provide further evidence that use of single-vision distance lenses in everyday locomotion may be advantageous for elderly multifocal wearers who have a high risk of falling.

No / Postural instability in older people is associated with an increased risk of falling. This experiment investigated the effects of different gaze strategies on postural stability in older people, when using distance single-vision compared with multifocal (progressive addition lens and bifocal) spectacles. METHODS: Eighteen healthy older habitual multifocal spectacle-wearers (mean age 72.1 +/- 4.0 years) participated in a randomised, cross-over study. Postural stability during quiet standing was assessed as the root mean square excursion in the centre of pressure (RMS-COP) in the antero-posterior direction. Ground reaction force data were collected (for 30 seconds), while subjects viewed one of two visual targets (one square metre) of different spatial frequencies and contrasts, while wearing either distance single-vision or multifocal (progressive addition and bifocal) spectacles. The visual targets were positioned either ahead at eye-level or on the ground (viewing distance 2.06 metres) and viewed under the following head-gaze conditions; 'head neutral-gaze forward', 'head flexed-gaze down' and 'head neutral-gaze down'. RESULTS: The type of spectacles worn or the target viewed had no significant effect on postural stability but postural stability deteriorated (antero-posterior RMS-COP excursion increased) in the 'head neutral-gaze down' compared with the 'head flexed-gaze down' and 'head neutral-gaze forward' conditions (5.9, 5.5 and 5.0 mm respectively, p < 0.001). CONCLUSIONS: Multifocal use had no effect on standing postural stability. Irrespective of spectacles worn, when fixating a visual target positioned at ground level, postural stability was better in the 'head flexed-gaze down' condition compared with the 'head neutral-gaze down' condition. A useful strategy to reduce falling in the older person might be to advise multifocal and distance single-vision spectacle-wearers to flex their heads rather than just lower their eyes when looking downwards.

INTRODUÇÃO: O Acidente Vascular Cerebral (AVC) causa alterações sensóriomotoras que levam a problemas do equilíbrio e limitações funcionais. Apesar dos avanços na reabilitação, muitos sujeitos não recuperam a independência nas atividades de vida diária, diminuindo sua qualidade de vida. Assim, a busca de estratégias eficazes para melhora da função motora e do equilíbrio é meta constante na fisioterapia. A realidade virtual (RV) tem sido proposta como uma nova ferramenta terapêutica para a reabilitação motora em pessoas com AVC, no entanto, seus efeitos sobre a função motora, atividade e participação são limitados. Assim, o objetivo deste estudo foi investigar os efeitos de um treinamento de equilíbrio, com uso de RV sobre os domínios de estrutura e função, atividade e participação, de acordo com a CIF, em pessoas com sequelas crônicas de AVC. MÉTODOS: Um ensaio clinico randomizado cego foi conduzido com 40 sujeitos. O treinamento consistiu em 14 sessões individuais de exercícios globais seguidos de treino de equilíbrio com uso de 8 jogos em RV (grupo experimental, GE) ou de exercícios similares realizados em mesma duração (grupo controle, GC). A sessão de membro inferior da escala Fugl-Meyer (FM-MI) foi utilizada para avaliação de estrutura e função, a atividade foi avaliada por meio da escala BESTest e de testes de equilíbrio em plataforma de força (LOS- máximo deslocamento para os lados afetado e preservado) e por meio do teste de caminhada de 6 minutos, e a participação foi avaliada por meio de questionário de qualidade de vida específico para AVE (EQVE-AVE). As avaliações foram realizadas antes (AT), depois do treino (DT) e após 60 dias do final do treino (FU). A ANOVA de medidas repetidas utilizando como fator os grupos (GE; GC) e avaliações (AT; DT e FU) foi realizada para cada variável, seguida do pós-hoc de Tukey. O nível de significância foi 5%. RESULTADOS: Houve interação na FM-MI (F=7,17, p= 0,001, poder observado= 0,92) e segundo o pós-hoc, o GE apresentou melhora significativa DT (p=0,0001) que se manteve no FU (p=0,0004). Houve interação na BESTest (F=5,99, p= 0,003, poder observado= 0,86) com melhora significativa DT (p=0,0001) e no FU (p=0,0004) no GE. Houve efeito de avaliação no LOS para o lado afetado (F=5,56, p=0,005, poder observado=0,84) e efeito de grupo (F=4,59, p=0,038, poder observado=0,55) para o lado preservado. Foi observado efeito de avaliação no teste de 6-min (F=8,74, p=0,0003, poder observado=0,96) e na EQVEAVE (F=13,73, p=0,0000, poder observado=0,99). CONCLUSÃO: A inclusão da RV no treino de equilíbrio promoveu melhora na estrutura e função e na atividade, mas não na participação de pessoas com sequelas crônicas de AVC / BACKGROUND: Among impairments which reduce functionality after Stroke, balance deficiency due to the asymmetric postural control associated with hemiplegia is the most frequent outcome, and persist through the chronic stage, increasing the risk factors for falls and decreasing independence in the activities of daily living. Thus, the investigation of new therapeutic tools in order to improve the balance recovery is essential. The use of Virtual Reality (VR) systems for rehabilitation has emerged as a novel advance in the motor rehabilitation field, however, the evidence about its effects on body function, activity and participation remains limited. Objectives: To investigate if a balance training performed in virtual reality (VR) plus general exercise could improve the body functions, activity and participation level according to the International Classification of Functioning, Disability, and Health (ICF) in people with chronic stroke. METHODS: A randomised controlled trial with a parallel group, assessor blinding and intention-to-treat analysis was conducted. Forty people with chronic stroke were randomised to receive 14 sessions of balance training performed in VR plus comprehensive exercises for the experimental group (EG) or similar balance training plus comprehensive exercises, for the control group (CG). The Lower Limb Subscale of the Fugl-Meyer (FM-LE) assessment was adopted as a measure of body function, the Balance Evaluation Systems Test (BESTest) and six-minute walk test (6MWT) as a measure of activity and the Stroke- Specific Quality of Life Scale (SSQOL) as a measure of participation. All outcome measures were administered before training, 1 week and 8 weeks after the end of training. Results: According to ANOVA for repeated measures there was an interaction between group (EG, CG) and time assessment before training, at 1 week and 8 weeks after training for FM-LE (F=7.17, p < 0.01, power =0.92) and BESTest (F=5.89, p < 0.01, power =0.86). The post-hoc test confirmed that the EG achieved greater improvements than CG in FM-LE and BESTest. In contrast, for the LOS to paretic side, 6MWT and SS-QOL tests there were effects for evaluation only (F=5.56, p=0.005, power=0.84), (F= 8.74, p < 0.001, power=0.96) and (F=13.73 p < 0.001, power=0.99) respectively. Conclusion: The inclusion of VR in a balance training program was fundamental to promote improvements in body functions and activity, but not in participation in people living with the aftermath of chronic stroke
