Introdução: A dor lombar crônica pode ser definida como dor ou desconforto persistente por mais de 12 semanas nos níveis lombar e sacral da coluna vertebral. Cerca de 5% dos pacientes apresentam comprometimento de raiz nervosa, e uma razão comum é a herniação discal. Os músculos multífido lombar (ML) e transverso do abdome (TrA) são preferencialmente acometidos frente a episódios de dor lombar. Contudo, há escassa literatura que tenha avaliado a fadiga do ML e a capacidade de ativação do TrA em indivíduos com e sem hérnia de disco lombar. Objetivo: Avaliar a fadiga do músculo multífido lombar e a capacidade de ativação do transverso do abdome em indivíduos com hérnia de disco e dor lombar crônica, e controle. Métodos: Participaram do estudo 60 indivíduos com idade entre 20 a 50 anos, divididos em dois grupos: Hérnia Lombar (GHL) com dor há mais de três meses (n=30) e Grupo Controle (GC) sem dor (n=30). A fadiga do multífido lombar foi avaliada com a eletromiografia de superfície durante a realização do teste de esforço de Sorensen e a capacidade de ativação do TrA pela Unidade de Biofeedback Pressórico (UBP). A dor foi avaliada com a escala visual analógica - EVA e questionário McGill de Dor, a incapacidade funcional pelo Índice de incapacidade de Oswestry e o relato de esforço percebido pela escala de Borg. O nível de significância adotado foi de 5%. Na análise dos dados de frequência mediana quanto menor o valor maior a fadiga. Resultados: Houve aumento da fadiga nos dois grupos, porém mais intensa no GHL (p=0,0001) proporcionando a instalação da fadiga em menor tempo (163 s). Na capacidade de ativação do TrA, o GHL apresentou ativação insuficiente (-0,9 mmHg) e GC próximo a valores ideais ( -3,9 mmHg). Na escala de Borg, houve diferença entre os grupos para o esforço inicial (p=0,0002), contudo não foi observado diferença para o esforço final (p=0,0611). O GHL apresentou dor moderada (6,4 cm) quando avaliada pela EVA e pelo Questionário McGill de dor nas categorias sensorial (19,2) afetiva (8,6) e total (36,3) e incapacidade funcional mínima. Conclusão: Os indivíduos com hérnia de disco e dor lombar crônica apresentam maior fadiga do músculo multífido lombar e ativação do transverso do abdome insuficiente quando comparados aos controles. / Introduction: Chronic low back pain can be defined as pain or discomfort lasting more than 12 weeks in the lumbar and sacral levels of the spine. About 5% of patients have nerve root impairment, and the more common etiology is the disc herniation. The lumbar multifidus (LM) and transversus abdominis (TrA) muscles are often affected in low back pain. However, the literature on the fatigue assessment of ML and the ability of TRA activation in individuals with and without lumbar disc herniation is scarce. Objective: To evaluate the lumbar multifidus muscle fatigue and transversus abdominis activation in individuals with disc herniation and chronic low back pain, and control. Methods: The study included 60 subjects aged 20 to 50 years, divided into two groups: lumbar herniated group (GLH) with pain for more than three months (n = 30) and control group (CG) without pain (n = 30). The fatigue of the lumbar multifidus was measured with surface electromyography during the Sorensen test and ability of activation of TRA with Unit Biofeedback pressure (PBU). Pain was assessed by visual analog scale - VAS and McGill pain questionnaire, functional disability by Oswestry Disability Index, and the reporting of perceived exertion with Borg scale. The significance level was established in 5%. Results: We found increased fatigue in both groups however more intense in GLH (p=0.0001) providing the onset of fatigue in less time (163 s). The ability to activate the TrA, the GLH showed insufficient activation (-0.9 mmHg) and CG near the ideal values (-3.9 mmHg). In Borg scale, difference was observed between groups for the initial effort (p = 0.0002), however no difference was observed for the final effort (p = 0.061). The GLH had moderate pain (6.4 cm) when assessed by the VAS and the McGill Pain Questionnaire in sensory (19.2), affective (8.6) and total (36.3) categories and minimal functional disability. Conclusion: Individuals with disc herniation and chronic low back pain have higher fatigue of lumbar multifidus and insufficient transversus abdominis muscle activation when compared to controls.

Aim: The aim of this study was to explore the concurrent validity between Pain Limitation List (PLL) and Functional Disability Inventory (FDI), the association between PLL and age and FDI and age, the difference between gender in PLL and FDI and possible floor or roof effects in the two tests. Method: The study was a cross-sectional study and had a descriptive correlational and comparative design. 86 children with chronic pain participated in the study. Result: The study showed that PLL had a concurrent validity with FDI (r=-0,740), p<0,001). There was a weak correlation between FDI and age (r=0,249, p<0,021) but PLL did not have a correlation with age and there was no difference between gender in PLL or in FDI. Also, there was no floor or roof effect for the two tests but it seems that PLL is slightly more sensitive for children and adolescents with less pain-related disability. Conclusion: according to this study, PLL has a concurrent validity. But to be able to use PLL as a reliable instrument, more studies who explore reliability and other types of validity is needed. / Syfte: Syftet för denna studie var att undersöka samstämmig validitet mellan the Pain Limitation List (PLL) och the Functional Disability Inventory (FD), samvariationen mellan ålder och PLL och ålder och FDI, skillnad mellan kön för PLL och FDI samt eventuella takeller golveffekter för de två testen. Metod: Studien var en tvärsnittsstudie och hade en beskrivande korrelerande och jämförande design. 86 barn med långvarig smärta deltog i studien. Resultat: Studien visade att PLL har en samstämmig validitet med FDI (r= -0,740, p<0,001), att det var en svag samvariation mellan FDI och ålder (r=0,249, p<0,021), ingen samvariation mellan PLL och ålder samt att det inte förelåg någon skillnad mellan könen i FDI och i PLL. Det fanns heller ingen tak- eller golveffekt för de två testen men det verkar som att PLL är något mer känslig för barn och ungdomar med mindre smärtrelaterad aktivitetsbegränsning. Konklusion: Enligt denna studie har PLL samstämmig validitet. Men för att kunna använda PLL som ett pålitligt instrument behöver fler studier undersöka instrumentets reliabilitet och andra typer av validitet.

The population of China is ageing. Accompanying this aging population, dementia and frailty have a growing importance. However there is little consensus on the association between dementia and frailty, in terms of how the criteria that are part of this two syndromes overlap, as both disorders are age-related and increase the risk for falls, further leading to loss of independence. To meet the above needs, the thesis describes research into different frailty diagnostic criteria, as well as its association with dementia symptoms. We examined cognitive measures that can be used for assessment of Mild Cognitive Impairment (MCI) and dementia screening (the Hopkins Verbal Learning Test, HVLT) and compared its discriminant ability with the commonly used cognitive screening tool, the Mini-Mental State Examination (MMSE) in distinguishing Cognitive Impairment (including MCI and dementia) from No Cognitive Impairment (NCI, normal controls) in two community-dwelling elderly Chinese populations and in one institutionalised elderly population in Shanghai, China. Subsequently we investigated whether physical and cognitive symptoms clustered together to form frailty phenotypes. We employed indicators that have been widely used to diagnose frailty, including physical measures (grip strength, Time-Up and Go test, 15 feet gait speed test and Berg balance test), and psychological measures (the HVLT and the MMSE) to predict cognitive impairment (CI) and frailty. Additionally, we described demographics (age, gender, education) and other potential modifiers when detecting cognitive impairment and functional disability. We then built up a model for possible frailty phenotype using various indicators. Lastly, we examined whether demographic (age, gender, education and profession), and lifestyle (smoking/alcohol history, exercise frequency, and dietary habit) could be used to predict future cognitive impairment. It was found that advanced age, lower education (no or primary level), and being vegetarian were significant risk factors for cognitive impairment. Furthermore, whereas high consumption of green vegetables is a protector against cognitive impairment, high intake of tofu was negatively related to cognitive performance among community-dwelling elderly in China. To meet the above needs, the thesis describes research into different frailty diagnostic criteria, as well as its association with dementia symptoms. We examined cognitive measures that can be used for assessment of Mild Cognitive Impairment (MCI) and dementia screening (the Hopkins Verbal Learning Test, HVLT) and compared its discriminant ability with the commonly used cognitive screening tool, the Mini-Mental State Examination (MMSE) in distinguishing Cognitive Impairment (including MCI and dementia) from No Cognitive Impairment (NCI, normal controls) in two community-dwelling elderly Chinese populations and in one institutionalised elderly population in Shanghai, China. Subsequently we employed these two cognitive measures to investigate whether they were part of the frailty syndrome among elderly from the community-based studies. We investigated whether physical and cognitive symptoms clustered together to form frailty phenotypes. We employed indicators that have been widely used to diagnose frailty, including physical measures (grip strength, Time-Up and Go test, 15 feet gait speed test and Berg balance test), and psychological measures (the HVLT and the MMSE) to predict cognitive impairment (CI). We found four distinct subtypes of elderly characterised by increasing care needs: 1. Persona elderly as defined by age >78, year of education<6 years, grip strength <11.8 KG, and a MMSE total score <25; 2. Persona Physical frailty (fitness), defined by a total score on the Timed-Up and Go (TUG) test >12.7 seconds and 15 feet gait speed >4.4 seconds; 3. Persona Cognitive impairment, defined by a MMSE total score <25, a HVLT Immediate Recall (IR) score <15, and a HVLT Delayed Recall (DR) <5; 4. Persona Physical frailty (balance,) defined by a Berg Balance test score of <53. Additionally, we described demographics (age, gender, education) and other potential modifiers when detecting cognitive impairment and functional disability. We then built up a model for possible frailty phenotype using various indicators, Frailty here was defined as: 1. Low BMI as measured by this algorithm: BMI= Weight (kg)/Height (m)2 2. Weakness (upper and lower body): grip strength in the lowest quintile, adjusted for gender; and TUG get up with assistance or unable to get up 3. Slowness (lower body): TUG score in the lowest quintile, adjusted for gender; and 15 feet gait speed in the lowest quintile, adjusted for gender; 4. Poor balance: Berg Balance test score in the lowest quintile, adjusted for gender; 5. Low physical activity: engaging in exercise less than once per week. An individual with 4 or more present frailty components out of a total of 7 was considered to be frail , whereas equal or less than 3 characteristics were hypothesized to be pre-frail . Those with no present frailty components were considered as robust. Lastly, we examined whether demographic (age, gender, education and profession), and lifestyle (smoking/alcohol history, exercise frequency, and dietary habit) could be used to predict future cognitive impairment (as defined by a HVLT IR score of ≤19). The results of our studies show that compared to the MMSE, the HVLT is superior in differentiating MCI and dementia from NCI, and is also less affected by demographic factors in detecting frailty. Furthermore, in the current study, physical, psychological, demographic and other modifiable risk factors cluster together into different phenotypes of cognitive impairment and functional disability in these cohorts. A phenotype of frailty is built up using BMI, grip strength, TUG, 15 feet gait speed, balance and exercise frequency as indicators. The most common was the elderly phenotype followed by the cognitively impaired. A novel finding of the current study is that only 4.8% (8 out 168) of the whole sample fulfilled all three categories in the current study (cognitive impairment, functional disability and frailty). Finally, advanced age, lower education (no or primary level), and being vegetarian were significant risk factors for cognitive impairment. Furthermore, whereas high consumption of green vegetables is a protector against cognitive impairment, high intake of tofu was negatively related to cognitive performance among community-dwelling elderly in China.

For people with a functional disability, the everyday life can consist of various limitations that affect the ability to self-determination. These people are often in need of help and support and are forced to rely on other people’s goodwill. In homes with special services the personnel have an important task because their will and abilities for a good nursing care determines the life of the clients. The purpose of this study is to understand how personnel in homes with special services relate to the clients self-determination in their work, both in concept of their interpretation and application of the term. The study was conducted through interviews with seven different personnel from six different group homes, all of them working with individuals that have moderate to severe functional disabilities. With the help from the interviews, we got an understanding of how our respondents look at the term self-determination, how they implement this in their work and what factors may affect the clients self-determination. The result indicate that the personnel we interviewed all agreed that the client’s self-determination is something they consider to be important, but that it’s difficult to work with this because there is different factors that affect the clients self-determination. These factors can for example be linked to the resources that are available, the personals attitude or the clients ability to express their will.

O cenário nacional aponta maior proporção de idosos e consequente aumento de expectativa de vida na população. Assim, o objetivo da atenção à saúde dos idosos é de manter sua funcionalidade, autonomia e independência por um maior tempo possível. Neste contexto, que surge a preocupação em se desenvolverem pesquisas que avaliem a funcionalidade desta população. O objetivo deste estudo foi de analisar o conceito de Incapacidade Funcional em idosos, utilizando o Modelo Híbrido de Desenvolvimento de Conceito, que consta de três fases: a Fase Teórica, a Fase de Campo e a Fase Analítica Final. A Fase Teórica foi desenvolvida por meio da Revisão Integrativa da Literatura; a busca dos estudos primários ocorreu nas bases de dados LILACS, MEDLINE E CINAHL, com a utilização de descritores controlados e não controlados delimitados de acordo com a especificidade de cada base de dados. Foram pré-selecionados 1.113 trabalhos, porém 58 foram elegíveis após aplicação dos critérios de inclusão. A Fase de Campo se deu em duas etapas: a primeira consistiu em aplicar uma entrevista semiestruturada no domicílio para identificar os idosos elegíveis para a segunda etapa, na qual se utilizou a técnica de realização de grupos focais. Foram realizados quatro grupos sendo dois de idosos com idades entre 60 e 79 anos, e dois com idosos com mais de 80 anos. Durante os grupos, foram abordados os antecedentes, os atributos e as consequências do conceito de incapacidade funcional. A análise dos grupos foi feita por meio da análise de conteúdo temática. Na Fase Analítica Final, os dados da Fase Teórica e de Campo foram identificados e analisadas suas semelhanças, divergências e diferenças. Os dados mostraram que a incapacidade funcional em idosos é multidimensional, está relacionada aos aspectos físicos, pessoais, sociais, ambientais e emocionais, sem que esteja restrita somente à presença de patologias ou à incapacidade em realizar atividades de vida diária de maneira independente, mas também no prejuízo da manutenção da autonomia e do bem-estar do idoso. A incapacidade funcional ocorre em distintos contextos, está relacionada à idade avançada, à presença de condições crônicas, resultados acumulativos de hábitos de vida, prejuízo no desempenho de papéis sociais e condições ambientais desfavoráveis. Os resultados da incapacidade funcional são deletérios e trazem prejuízo tanto para o idoso, quanto para a família, estão relacionados à diminuição da expectativa e da qualidade de vida, perda da independência e autonomia, ao aumento de custos, adequações ambientais, e principalmente ao prejuízo emocional. O estudo de conceito de incapacidade funcional no idoso com a utilização da metodologia do Modelo Híbrido permitiu fortalecer a compreensão e consequente utilização na prática com o idoso / The national setting points to a greater proportion of elderly individuals and a consequent increase in the population\'s life expectancy, thus, the objective of the healthcare of the elderly stands on the maintenance of their functionality, autonomy and independence for as long as it is possible. In this context, a concern emerges regarding the development of studies to assess the functionality of this population. The aim of this study was to analyze the concept of functional disability in elderly individuals using the Hybrid Model of Concept Development. This model is comprised of three phases, namely the Theoretical Phase, the Field Phase and the Final Analytical Phase. The Theoretical Phase was developed by means of a literature integrative review, in which the search for primary studies took place in the LILACS, MEDLINE and CINAHL databases with the use of controlled and non- controlled descriptors that were limited according to the specificity of each database. A total of 1,113 studies were preselected, however only 58 were found eligible after the application of the inclusion criteria. The Field Phase took place in two steps. The first step consisted of a semi-structured interview in the house of the elderly individuals for identification of those who were eligible for the second step; the focus group technique was used in this moment. Four groups were performed, with two groups including elderly individuals between 60 at 79 years of age and two groups including elderly individuals over 80 years of age. During the groups, the researchers approached the antecedents, attributes and consequences of the concept of functional disability, and the groups were analyzed by means of the thematic content analysis. In the Final Analytical Phase, the data collected in the Theoretical and Field Phases were identified and their similarities, divergences and differences were analyzed. These data showed that functional disability in the elderly is multidimensional. It is related to physical, social, personal, environmental and emotional aspects, not restricted only to the presence of pathologies or the incapability of performing daily living activities independently, but also in the damage of the maintenance of the autonomy and wellbeing of the elderly. Functional disability occurs in different contexts, being related to the old age, the presence of chronic conditions, accumulative results of life habits, damage in the performance of social roles and unfavorable environmental conditions. The results of functional disability are damaging and bring harm both to the individuals and to their families, being related to reduced expectancy and quality of life, loss of independence and autonomy, increased costs, environmental adjustments and, especially, to emotional damage. The study of the concept of functional disability in the elderly with the use of the Hybrid Model methodology has allowed to reinforce its understanding and consequent use in the practice with the elderly

Objetivos: Investigar a prevalência de incapacidade funcional segundo fatores sociodemográficos, comportamentais, relacionados à saúde e à morbidade referida, em idosos residentes em Ribeirão Preto, SP, em 2007 e investigar o efeito independente destes fatores sobre a incapacidade funcional. Material e Métodos: estudo epidemiológico de base populacional, com delineamento transversal, integrante do Projeto EPIDCV cuja coleta de dados foi conduzida entre 2007 e 2008. O processo de amostragem foi desenvolvido em três estágios. A variabilidade introduzida, principalmente na terceira fração de amostragem, foi corrigida por meio do cálculo de pesos amostrais que levaram em consideração o \"número de unidades elegíveis de cada domicílio\" e as taxas de \"não resposta\", em cada setor censitário, originando uma amostra ponderada (nw) de 2.471 participantes com 30 anos ou mais, entre os quais foram identificados 536 idosos (nw). Para a avaliação da dependência na realização das atividades da vida diária (desfecho) foi utilizado Questionário estruturado e validado para estudos epidemiológicos de base populacional. As prevalências do desfecho foram calculadas por pontos e por intervalos com 95% de confiança, segundo variáveis sociodemográficas, comportamentais, relacionadas à saúde e à morbidade referida. Para identificar os fatores associados à incapacidade funcional, utilizou-se a Regressão de Poisson para obtenção das razões de prevalências (RP), estimadas por pontos e por intervalos, segundo as variáveis componentes de cada um dos grupos acima descritos. Resultados: A prevalência bruta de incapacidades foi 50,31% (IC 95%: 42,04%-58,57%). As seguintes variáveis apresentaram associação global (p<0,05) com o desfecho: variáveis sociodemográficas (sexo, faixas etárias, escolaridade, condição de trabalho, renda familiar, contribuição da renda do idoso sobre a renda familiar e Indicador Econômico de Ribeirão Preto-IERP); variáveis comportamentais (média diária de tempo sentado); variáveis relacionadas à saúde (hipertensão arterial, doença isquêmica do coração, nº de medicamentos nos últimos 15 dias, baixo desempenho cognitivo e razão cintura/altura); variáveis relacionadas à morbidade referida, (artrite, reumatismo ou artrose, bronquite, prisão de ventre, catarata, problemas de coluna, nº de doenças referidas, acuidade visual, acuidade auditiva, estado de saúde comparado à família e saúde autorreferida). Nos modelos multivariados, após o ajustamento simultâneo intragrupos (modelos finais), permaneceram independentemente associadas às incapacidades as variáveis adiante mencionadas: sociodemográficas (faixas etárias, escolaridade, trabalho e contribuição com a renda familiar); comportamentais (média diária de tempo sentado> 355 min/dia); relacionadas à saúde (hipertensão arterial, doença isquêmica do coração, uso de cinco ou mais medicamentos nos últimos 15 dias e baixo desempenho cognitivo); morbidade referida (duas ou mais doenças referidas e baixa acuidade auditiva). Conclusões: A elevada prevalência de incapacidades em idosos de Ribeirão Preto, bem como a presença de associações entre variáveis potencialmente modificáveis e o desfecho, impõem a necessidade de medidas específicas de promoção e prevenção em saúde que resultem em melhora da qualidade de vida deste estrato populacional já bem representado nas últimas pirâmides populacionais do município. / Objectives: To investigate the prevalence of functional disability according to sociodemographic, behavioral, health-related and referred morbidity-related factors in elderly people living in Ribeirão Preto, SP, in 2007 and to investigate the independent effect of these factors on the functional disability. Material and Methods: population-based, epidemiological study with cross-sectional design, part of the EPIDCV Project, whose data were collected between 2007 and 2008. The sampling process was developed in three phases. The variability, mainly introduced in the third sampling fraction, was corrected by calculating sampling weights that considered the \"number o eligible units at each household and the \"non-response\" rates in each census tract, resulting in a weighted sample (nw) of 2,471 participants aged 30 years or older, among whom 536 elderly (nw) were identified. To assess the dependence for the accomplishment of the activities of daily living (outcome), a structured and validated questionnaire for population-based epidemiological studies was used. The prevalence rates of the outcome were calculated by points and 95% confidence intervals, according to sociodemographic, behavioral, health-related and referred morbidity-related variables. To identify the factors associated with functional disability, Poisson\'s Regression was used to obtain prevalence ratios (PR), estimated by points and intervals, according to the variables in each of the groups described above. Results: The crude prevalence of disabilities corresponded to 50.31% (CI 95%: 42.04%-58.57%). The following variables revealed a global association (p<0.05) with the outcome: sociodemographic variables (gender, age ranges, education, work condition, family income, contribution of elderly\'s income to family income and Economic Indicator of Ribeirão Preto-EIRP); behavioral variables (daily mean of sitting time); health-related variables (arterial hypertension, ischemic heart diseases, number of medicines taken in the last 15 days, low cognitive performance and waist/height ratio); referred morbidity-related variables (arthritis, rheumatism or arthrosis, bronchitis, constipation, cataract, back problems, number of reported illnesses, visual acuity, auditory acuity, health condition compared with family and self-reported health). In the multivariate models, after simultaneous intragroup adjustment (final models), the following variables remained independently associated with the outcome: sociodemographic (age ranges, education, work and contribution to family income); behavioral (daily mean of sitting time > 355 min/day); healthrelated (arterial hypertension, ischemic heart disease, use of five or more medicines in the last 15 days and low cognitive performance); referred morbidity (two or more referred illnesses and low auditory acuity). Conclusions: The high prevalence of disabilities among elderly in Ribeirão Preto and the presence of associations between potentially modifiable variables and the outcome impose the need for specific health promotion and prevention measures that result in a better quality of life for this population group, which is already well represented in the city\'s most recent population pyramids.

A Estenose de Canal Lombar (ECL) é caracterizada pela redução do espaço de elementos neurais ou vasculares da coluna lombar. Os sintomas incluem dor e/ou parestesia em membros inferiores, região lombar, e glúteos e Claudicação Intermitente Neurogênica. O tratamento conservador é a escolha inicial para o manejo de pacientes com ECL, por isso é importante a identificação de diferentes estratégias para o tratamento conservador, e a compreensão das alterações em parâmetros funcionais que estes tratamentos geram. O presente estudo objetivou comparar os efeitos de 24 sessões de Fisioterapia Aquática (GFA) e de Fisioterapia Solo (GFS) nos parâmetros espaço-temporais de marcha, equilíbrio, nível de dor percebida, incapacidade, capacidade física funcional, medo de movimento e níveis de depressão em indivíduos com ECL. Para observação das diferenças entre os grupos e momentos foi realizado o teste de Equações de Estimativa Generalizada no software SPSS versão 20.0. Para todas as análises o índice de significância adotado foi de 95% (α=0,05). Os níveis de incapacidade, dor, e estados depressivos reduziram, bem como a velocidade de caminhada autosselecionada e o índice de reabilitação locomotora aumentaram após as intervenções sem diferenças entre os grupos. O GFA apresentou melhora dos parâmetros espaço-temporais de marcha em velocidade fixa, redução da ingesta de medicação analgésica, e redução da média semanal de dor mais cedo que o GFS. O GFS demonstrou maior melhora da mobilidade funcional indicando um melhor equilíbrio após a intervenção em comparação ao GFA. Tratamentos fisioterapêuticos estruturados com associação de exercícios de estabilização de tronco, alongamentos e terapia manual mostram-se eficazes para melhora da incapacidade, dor, depressão e parâmetros de marcha em indivíduos com Estenose da Canal Lombar, sendo o meio aquático potencializador da resposta analgésica e da melhora em parâmetros espaço temporais de marcha e o solo potencializador da melhora do equilíbrio. / Lumbar Spinal Stenosis (LSS) is characterized by a reduction in the space of vascular and neuronal elements of the spinal canal space. Symptoms include pain and/or paresthesia in lower limbs, lumbar region and buttocks, and Neurogenic Intermittent Claudication. Conservative treatments are the choice for initial management of patients with LSS, therefore it is important to identify different conservative treatments strategies and understanding of the changes in functional parameters that those treatments cause. The present study aimed to compare the effects of 24 physiotherapy sections of Aquatic Physiotherapy (GFA) and Ground Physiotherapy (GFS) in spatiotemporal gait parameters, balance, perceived level of pain, disability, functional exercise capacity, fear of movement, and clinical depression in individuals with LSS. Generalized Estimating Equations were made to observe the differences between groups and moments on SPSS software version 20.0. For all tests, the significance level was 95% (α = 0,05). Disability, pain and depressive symptoms reduced and selfselected walking speed and locomotor rehabilitation index increased after interventions with no differences between groups. GFA improve spatiotemporal gait parameter in fixed speed, reduced analgesic medication, and show an earlier reduction in weekly pain. GFS improve functional mobility indicating a better balance in comparison to GFA. Physiotherapeutic treatments structured with the association of stabilization exercises, stretching exercises and manual therapy are efficient in improving disability, pain, depression and gait parameters in Lumbar Spinal Stenosis patients, water environment potentiate analgesic and spatiotemporal improvements, and land potentiate balance improvements.
