Abstract: In iduals after stroke present several motor impairments, which reduced the functional capacity. The understanding of modifiable factors which are related to functional capacity in in iduals with chronic stroke could better direct clinical practice. However, the mechanisms that could influence functional capacity in in iduals with chronic stroke are not fully understood. This study aimed to determine which modifiable variables would best predict self‐reported functional capacity after stroke. Cross‐sectional. Research laboratory setting. Ninety two in iduals with chronic stroke, who had a mean age of 60 (SD 13) years and a time since the onset of the stroke of 52 (67) months. Regression analysis of cross‐sectional data was used to investigate whether body mass index, habitual walking speed, physical activity levels, fatigue, motor recovery, walking distance, and residual strength deficits of the lower limb muscles would predict self‐reported functional capacity. Habitual walking speed alone explained 48% of the variance in functional capacity. When fatigue was included in the model, the explained variance increased to 55%. Habitual walking speed and fatigue were significant predictors of self‐reported functional capacity in in iduals with chronic stroke. These in iduals may increase their functional capacity with interventions aimed at increasing walking speed and reducing fatigue.

Abstract: To determine, in Brazil, the proportion of in iduals who return to a paid work after stroke, and the factors which predict this. A prospective observational cohort study was carried out for six months. Participants were recruited early after stroke from four public hospitals. The outcome of interest was return to work, and the following predictors were investigated: age, sex, education, marital status, contribution to household income, type of work, independence, and depression. Logistic regression was used to identify multivariate predictors of return to work. Of the 117 included participants, 52 (44%) had returned to work by 6 months. Contribution to household income (OR 2.4 95% CI 1.0 to 5.9), being a white-collar worker (OR 4.0 95% CI 1.8 to 8.6) and being independent in daily activities at 3 months (OR 10.6 95% CI 2.9 to 38.3), in combination, positively predicted return to work. Less than 50% of stroke survivors returned to work six months after stroke. Among predictors, only the level of dependence in daily activities is a modifiable factor. Interventions aimed at reducing disability after stroke might increase rates of return to work.Implications for rehabilitationIn Brazil, less than 50% of stroke survivors returned to work six months after stroke.Clinicians may collect information regarding household income, type of work and dependence in daily activities to estimate chances of returning to work, in developing countries.Being independent at 3 months was the strongest predictor of return to work therefore, interventions aimed at reducing disability after stroke may increase rates of return to work.

Abstract: O objetivo foi descrever e comparar diferenças na restrição na participação social de in íduos após acidente vascular encefálico (AVE) na fase crônica, considerando as deficiências, limitações em mobilidade e fatores pessoais. A restrição na participação social foi mensurada pelo LIFE-H 3.1-Brasil as deficiências pela Escala de Depressão Geriátrica e Escala de Fugl-Meyer (EFM) as limitações em mobilidade pela velocidade de marcha e Timed Up & Go (TUG) e os fatores pessoais incluíram sexo, idade, situação familiar e tempo de evolução pós-AVE. Observou-se restrição significativa na área de recreação. Em geral, restrições na participação social foram observadas em participantes com escores ≤28 na EFM-membro inferior, sintomas de depressão, marcha comunitária limitada, risco de quedas e tempo de evolução ≤5 anos. Aqueles com escores ≤45 na EFM-membro superior apresentaram maior restrição em algumas áreas das atividades diárias. As mulheres apresentaram maior restrição em papéis sociais. Os resultados sugerem que deficiências e limitações relacionadas aos membros inferiores, sintomas depressivos e tempo de evolução devem ser considerados na avaliação, quando o objetivo da reabilitação for aumentar a participação social de in íduos pós-AVE.

Abstract: Após o acidente vascular encefálico, mais de 80% dos sobreviventes apresentam hemiparesia e a fraqueza muscular é citada como uma importante deficiência responsável pela redução do uso funcional do membro superior parético. Nesse contexto, evidências científicas sugerem o treinamento resistido como um importante componente dos programas de reabilitação. Estudos relacionados à recuperação destes in íduos apresentam fundamentação que apóia a utilização do treinamento resistido para a recuperação da função do membro superior parético. Entretanto, esta modalidade de treinamento pode não resultar em benefícios para todos os in íduos hemiparéticos e seus efeitos estariam condicionados ao nível de acometimento inicial do in íduo. Ainda não há resultados conclusivos sobre a influência do fortalecimento muscular no desempenho motor do membro superior parético, o que sugere a aplicação do treinamento resistido como intervenção terapêutica complementar à reabilitação funcional. O objetivo deste estudo foi analisar, por meio de revisão bibliográfica, a influência do fortalecimento muscular no desempenho motor dos membros superiores de in íduos.

Abstract: Although the significance of respiratory muscle training has been established in the literature, there is a need to understand the participants' perceptions of the benefits of this intervention. To understand how in iduals who had a stroke perceive changes in their body functions and structures, activities, and participation after a high-intensity respiratory muscle training intervention and to understand their perceptions of the benefits and limitations of a home-based intervention. Qualitative study. Community-dwelling patients. Fifteen in iduals who had a stroke. For this qualitative study, interviews were conducted using a semistructured questionnaire about topics related to participation in a home-based respiratory muscle training intervention. The interviews were transcribed and analyzed using thematic content analysis. Fifteen participants were interviewed. Most of the participants reported positive perceptions of body functions and structures, grouped into two thematic categories (breathing and speech) activity, also grouped into two thematic categories (walking and domestic activities) and participation, grouped into one thematic category (community-leisure activities). Answers about the benefits of a home-based intervention were grouped into three thematic categories (no need to leave home, commitment to training, and comfort). All participants reported that they would recommend the intervention to other stroke patients and that they were either satisfied or very satisfied with the intervention. Most (80%) participants did not consider the intervention difficult to perform. In iduals who had experienced a stroke perceived the benefits of high-intensity home-based respiratory muscle training in all components of function.

Abstract: To determine whether minute ventilation-to-carbon dioxide production (VE/VCO Regression analysis of cross-sectional data from 50 in iduals between 1 and 4 years post-stroke was carried out to investigate the prediction of energy expenditure during stair ascent/descent. In addition, discriminant analysis was carried out to investigate the discrimination between walking abilities for energy expenditure: community (walking speed ≥ 0.8 m/s) and non-community (walking speed < 0.8 m/s) walkers. Oxygen pulse and rate pressure product were retained in the model. Oxygen pulse alone explained 70% of the variance in energy expenditure during stair ascent/descent. By adding rate pressure product, 79% of the variance was explained. Energy expenditure was able to discriminate the community from the non-community walkers, with a cutoff value of 13.8 ml∙kg Oxygen pulse and rate pressure product significantly predicted energy expenditure during stair ascent/descent in in iduals with chronic stroke. Energy expenditure during stair ascent/descent discriminated community from non-community walkers.

Abstract: Since physical inactivity is the major risk factor for recurrent stroke, it is important to understand how level of disability impacts oxygen uptake by people after stroke. This study investigated the nature of the relationship between level of disability and oxygen cost in people with chronic stroke. Level of walking disability was measured as comfortable walking speed using the 10-m Walk Test reported in m/s with 55 ambulatory people 2 years after stroke. Oxygen cost was measured during 3 walking tasks: overground walking at comfortable speed, overground walking at fast speed, and stair walking at comfortable speed. Oxygen cost was calculated from oxygen uptake ided by distance covered during walking and reported in ml∙kg The relationship between level of walking disability and oxygen cost was curvilinear for all 3 walking tasks. One quadratic model accounted for 81% (95% CI [74, 88]) of the variance in oxygen cost during the 3 walking tasks: [Formula: see text] DISCUSSION: The oxygen cost of walking was related the level of walking disability in people with chronic stroke, such that the more disabled the in idual, the higher the oxygen cost of walking with oxygen cost rising sharply as disability became severe. An equation that relates oxygen cost during different walking tasks according to the level of walking disability allows clinicians to determine oxygen cost indirectly without the difficulty of measuring oxygen uptake directly.

Abstract: To determine the Duke Activity Status Index (DASI) cut-off scores and verify if they would be able to discriminate between chronic stroke in iduals, who had poor, from those who had good functional capacity (FC). Cross-sectional study, where 92 in iduals with chronic stroke had their FC measured by DASI scores and were classified into community and non-community walkers. Both the receiver operating characteristic and the area under the curve were used to determine the best DASI cut-off values that could discriminate between in iduals, who had poor, from those who had good FC. Binary logistic regression analysis is used to investigate the ability of DASI scores in predicting community walkers. DASI cut-off value of 31.95 showed to be sensitive and specific to differentiate between in iduals, who had poor from good FC. The regression analysis revealed that the chance of in iduals, who had better FC (≥ 31.95) be community walkers was 10.69 (95%CI:4-32.75) times higher than that of those who had poor FC (< 31.95). The model demonstrated good predictive ability. The DASI cut-off value of 31.95 showed to be sensitive and specific to distinguish between chronic stroke in iduals, who had poor, from those who had good FC.IMPLICATIONS FOR REHABILITATIONThe identification of in iduals, who have good and poor functional capacity, is important for clinical reasoning and decision-making in stroke rehabilitation.The Duke Activity Status Index (DASI) is a clinically useful tool for the assessment of functional capacity, based upon the performance of common daily living activities.The DASI cut-off of 31.95 points was able to discriminate between in iduals with stroke, who had poor, from those who had good functional capacity.The chance of in iduals, who had good functional capacity (DASI ≥ 31.95) be community walkers was 10.69 times higher than that of those who had poor functional capacity (DASI < 31.95).The findings support the use of the DASI as a simple tool for the assessment of functional capacity, especially in low-resource settings.

Abstract: Aim: To translate, cross-cultural adapt and investigate the measurement properties of the 25-point Friendship Scale to Brazilian-Portuguese. Methods: Translation and adaptation of the 25-point Friendship Scale to Brazilian-Portuguese was conducted at first. Then, the new version was administered to 160 Brazilians to investigate test-retest reliability, internal consistency, standard error of the measurement (SEM), minimal detectable change (MDC), ceiling and floor effects, and concurrent validity. To investigate concurrent validity, the Brazilian–Portuguese version of the 0-100 EuroQol Visual Analog Scale (EQ VAS) was used to assess people’s self-reported health status. Results: The Brazilian-Portuguese version has good to excellent reliability (ICC of 0.76, 95% CI 0.61 – 0.85) and had moderate internal consistency (Cronbach’s alpha value of 0.78, 95% CI: 0.73 – 0.83). To avoid measurement error and to exceed variability, scores need to be greater than 1.33 (SEM) and 3.69 (MDC) on the 25-point scale, respectively. There was no ceiling and floor effects. For concurrent validity, there was a small positive correlation between the Friendship Scale and the EQ VAS (Spearman rs = 0.24 p .01). Conclusions: The new Brazilian–Portuguese version of the Friendship Scale has acceptable measurement properties to assess people over 18 years old’s perception of social isolation.

Abstract: A Modified Gait Efficacy scale (mGES) avalia a percepção do in íduo sobre o seu nível de confiança na marcha, em circunstâncias desafiadoras. Para sua aplicação na população brasileira, é necessário que seja realizada a sua adaptação transcultural. Este estudo objetivou realizar a adaptação transcultural do mGES para uso no Brasil. O processo de adaptação seguiu diretrizes padronizadas, sendo realizado em cinco etapas: tradução, retrotradução, síntese das traduções, avaliação pelo comitê de especialistas e teste da versão pré final. A versão pré final foi aplicada em 12 in íduos pós-Acidente Vascular Encefálico (AVE), que foram indagados sobre como interpretaram cada item. O processo de adaptação seguiu todas as recomendações propostas, sendo necessárias apenas pequenas alterações em três itens, para possibilitar melhor compreensão. Resultados satisfatórios foram obtidos no teste da versão pré final, uma vez que não houve nenhum problema quanto à redação e clareza dos itens ou ao objetivo da escala. A versão final da mGES-Brasil demonstrou satisfatório grau de equivalência semântica, conceitual e cultural, em relação à versão original, e pode, ser utilizada em contextos clínicos e de pesquisa no Brasil, para avaliar o nível de confiança na marcha de in íduos pós-AVE.
