Acute predictors of self-rated health in individuals with stroke at 3 and 12 months after hospital discharge.

BACKGROUND: Self-rated health (SRH) is the perception of an individual regarding their health and an indicator of health status. Identifying predictors of SRH allows the selection of evidence-based interventions that mitigate factors leading to poor SRH and the identification of individuals at risk of worse SRH. OBJECTIVE: To determine the acute predictors of general and time-comparative SRH of individuals with stroke at 3 and 12 months after hospital discharge, considering personal, physical, and mental functions. METHODS: A prospective study was developed to assess general and time-comparative SRH at 3 and 12 months after hospital discharge according to 2 questions ("In general, how would you say your health is?" and "Compared to a year ago, how would you rate your general health now?"). Potential acute predictors analyzed were personal (age, sex, comorbidities, socioeconomic status, and family arrangement), physical (stroke severity, motor impairment, and independence for basic activities of daily living [ADLs]), and mental (cognitive) functions. RESULTS: Age (adjusted odds ratio [aOR]=2.10) and independence in basic ADLs (aOR=0.29) were significant predictors of SRH at 3 months; at 12 months, no significant predictor was found. Motor impairment (aOR=3.90) was a significant predictor of time-comparative SRH at 3 months; at 12 months, sex (aOR=0.36) and independence in basic ADLs (aOR=0.32) were significant predictors. CONCLUSIONS: At 3 months, individuals with stroke who were ≥65 years old and dependent on basic ADLs were more likely to have worse general SRH, while those with higher motor impairments were more likely to have worse time-comparative SRH. At 12 months, women and individuals dependent on basic ADLs were more likely to have worse time-comparative SRH.

Individuals with stroke three months after hospital discharge reported worse quality of life during the COVID-19 pandemic.

PURPOSE: To compare quality of life (QOL) of individuals with stroke three months after hospital discharge, using generic and specific QOL measures, before and during the COVID-19 pandemic. METHODS: Individuals, who were admitted to a public hospital, were recruited and evaluated before (G1) and during (G2) the COVID-19 pandemic. The groups were matched for age, sex, socio-economic status, and levels of stroke severity (National Institutes of Health Stroke Scale) and functional dependence (Modified Barthel Index). After three months of hospital discharge, they were evaluated and compared using generic (Short-form Health Survey 36: SF-36) and specific (Stroke Specific Quality of Life: SSQOL) QOL measures. RESULTS: Seventy individuals were included (35 in each group). Statistically significant between-group differences were found for both total SF-36 (p=0.008) and SSQOL (p=0.001) scores, indicating that individuals reported worse QOL during the COVID-19 pandemic. Furthermore, G2 also reported worse generic QOL related to the SF-36 domains of physical functioning, bodily pain, general health perception, and emotional role limitations (p < 0.01) and worse specific QOL related to following SSQOL domains: Family roles, mobility, mood, personality, and social roles (p < 0.05). Finally, G2 reported better QOL related to energy and thinking (p < 0.05) SSQOL domains. CONCLUSION: In general, individuals with stroke, who were evaluated during the COVID-19 pandemic three months after hospital discharge, reported worse perceptions of QOL in several domains of both generic and specific QOL measures.

Physical activity level of post-stroke individuals that use the Brazilian public health system / Nível de atividade física de indivíduos pós-AVC usuários do sistema público de saúde brasileiro

Abstract Introduction: According to studies from developed countries, post-stroke individuals commonly have a low level of physical activity. Considering the benefits of maintaining a good level of physical activity in these subjects, it is important to provide specific and complete information, based on the assessment of all dimensions of physical activity, which supports interventions. Objective: To compare the physical activity levels between individuals with stroke and matched healthy individuals that use the public health system in Brazil considering the different dimensions of physical activity. Methods: Individuals with stroke (n = 11) and matched healthy individuals (n = 11) were assessed. Physical activity levels, considering all dimensions -duration (> 3 MET), frequency (number of steps) and intensity (mean total energy expenditure per day) - were assessed using SenseWear® monitor for seven days. Descriptive statistics and between-groups comparisons were performed (α = 0.05). Results: The physical activity levels were significantly lower in individuals with stroke when compared to matched healthy individuals, considering all dimensions. The between-group differences in activity duration, frequency, and intensity were 74 minutes/day, 5,274 steps/day, and 2,134kJ/day, respectively. Conclusion: Individuals with stroke users of the Brazilian public health system have lower physical activity levels in different dimensions of physical activity than matched healthy individuals. The assessment of the physical activity level of post-stroke individuals is important for decision making in public health programs.

Resumo Introdução: De acordo com os estudos realizados em países desenvolvidos, indivíduos pós-acidente vascular cerebral (AVC) comumente apresentam baixo nível de atividade física. Considerando os benefícios desses indivíduos manterem um bom nível de atividade física, é importante fornecer informações específicas e completas a partir da avaliação de todas as dimensões da atividade física que guiem as intervenções. Objetivo: Comparar o nível de atividade física de indivíduos pós-AVC e saudáveis pareados, usuários do sistema público de saúde brasileiro, considerando as diferentes dimensões da atividade física. Métodos: Foram avaliados indivíduos pós-AVC (n = 11) e seus pares saudáveis (n = 11). O nível de atividade física, considerando as diferentes dimensões - duração (> 3 equivalentes metabólicos), frequência (número de passos) e intensidade (média do gasto energético total por dia) -, foi avaliado com o monitor SenseWear® por sete dias. Foram utilizadas estatísticas descritivas e comparações entre os grupos (α = 0,05). Resultados: O nível de atividade física foi significativamente menor nos indivíduos pós-AVC comparados aos seus pares saudáveis, considerando todas as dimensões. A diferença entre os grupos na duração, frequência e intensidade da atividade foi de 74 minutos/dia, 5274 passos/dia e 2134 kJ/dia, respectivamente. Conclusão: Indivíduos pós-AVC usuários do sistema público de saúde brasileiro têm menor nível de atividade física nas diferentes dimensões da atividade quando comparados aos seus pares saudáveis. A avaliação do nível de atividade física em indivíduos pós-AVC é importante para a tomada de decisões em programas de saúde pública.

Knee extensor muscles strength indicates global lower-limb strength in individuals who have suffered a stroke: A cross-sectional study.

OBJECTIVES: This study had three aims: (1) to evaluate the relationships between the paretic knee extensor muscle strength and global lower-limb strength in individuals who had suffered a sub-acute/chronic stroke, (2) to determine whether global lower-limb strength, sex, body mass index, or age could predict knee extensor muscle strength, and 3) to investigate whether the results obtained via a Modified Sphygmomanometer Test (MST) would be similar to those obtained using a hand-held dynamometer. METHODS: This was a cross-sectional study, performed at a research laboratory, at participants' homes, or at outpatient clinics. Forty-two individuals with a sub-acute stroke and 45 individuals with a chronic stroke participated. Maximum isometric strength of the paretic lower-limb muscles (i.e. hip, knee, and ankle flexors/extensors, hip abductors) was measured using the MST and a hand-held dynamometer. RESULTS: Significant and high correlation coefficients were found between knee extensor muscle strength and global lower-limb strength as measured by the combined strength values of 6 lower limb muscle groups in individuals with sub-acute (0.81≤r≤0.88; p<0.05) and chronic (0.82≤r≤0.85; p<0.05) stroke. Step-wise multiple regression analysis revealed that only global lower-limb strength was retained in the model and accounted for 66-78% and 67-72% (p<0.001) of the variance in knee extensor muscle strength at the sub-acute and chronic phases post-stroke, respectively. The results obtained via the MST were similar to those obtained using the hand-held dynamometer. CONCLUSION: Paretic knee extensor muscles strength, assessed using a MST or a hand-held dynamometer, indicates global lower-limb strength in individuals with a sub-acute or chronic stroke.
