General and Specific Quality of Life Course of Individuals with Different Levels of Stroke Severity: A One-Year Prospective Longitudinal Study.

OBJECTIVES: To compare the course of generic and specific health-related quality of life (HRQOL) of individuals with stroke, and its physical, mental, and social domains, at three, six, and 12 months after hospital discharge, considering the levels of stroke severity. METHODS: This is a longitudinal study, in stroke individuals, assessed during hospital admission by the National Institutes of Health Stroke Scale (NIHSS), and divided into mild (NIHSS ≤3) or moderate/severe (NIHSS ≥4) disease. At three, six, and 12 months after hospital discharge, the individuals were assessed for generic (Short Form Health Survey-36: total score and physical and mental domains) and specific (Stroke Specific Quality of Life Scale: total score and social domain) HRQOL. A 2 × 2 repeated measures analysis of variance (ANOVA) with post-hoc was applied. RESULTS: 146, 122, and 103 individuals were assessed at three, six and 12 months, respectively HRQOL courses showed different behaviors according to stroke severity (3.37≤F ≤ 4.62; 0.010≤p ≤ .036). Individuals with mild stroke showed significant changes in the physical domain, with a reduction between three and six months, and an increase between six and 12. Moderate/severe individuals showed a significant increase in all HRQOL variables between three and six months, and a maintenance of values for almost all variables, except for physical domain, which improved significantly between three and six months, and got significantly worse between six and 12. CONCLUSIONS: HRQOL during the first year after stroke showed distinct trajectories, being stroke severity an important factor in identifying stroke subjects at risk of HRQOL decline. CLINICAL IMPLICATIONS: These results demonstrate the importance of considering not only the phase of the stroke, the severity, and the general and specific HRQOL, but also the physical, social, and mainly the mental domain, which has long been neglected, when assessing this population.

Telephone-based application of the Activities of Daily Living Questionnaire in patients with Parkinson's disease.

BACKGROUND: The Activities of Daily Living Questionnaire (ADLQ) focuses on assessing the ability to perform activities of daily living (ADLs) based on the self-perception of individuals with Parkinson's disease (PD). A Brazilian Portuguese version of the questionnaire is available (ADLQ-Brazil), and further investigation is needed to fully assess its measurement properties. OBJECTIVE: To investigate construct and concurrent validity of the telephone-based administration of the ADLQ-Brazil with community individuals with PD. METHODS: There were 50 adults with PD (mean age: 68 ± 9.5 years) invited to answer the ADLQ-Brazil on two randomized occasions, face-to-face and by telephone, 7 to 10 days apart. Clinical-based measures including the Movement Disorder Society-Sponsored Revision of the Unified Parkinson Disease Rating Scale, Timed Up and Go Test, Nine Hole Peg Test, Mini-Balance Evaluation Systems Test, Apathy Scale, Beck Depression Inventory, Modified Fatigue Impact Scale, and Parkinson Disease Quality of Life Questionnaire were applied during the first session, to establish construct validity. RESULTS: The total scores on the ADLQ-Brazil were significantly associated with the clinical-based measures, thus providing evidence of construct validity. No significant differences were observed between the mean scores obtained with the face-to-face and telephone-based administration of the questionnaire (95%CI = 0.997). A high level of agreement was found in the total scores obtained between both applications of the ADLQ-Brazil (95%CI = 0.994-0.998), and most of the individual items had, on average, moderate agreement. CONCLUSION: The findings provide psychometric support for the ADLQ-Brazil as a telephone interview to assess the performance of ADLs in individuals with PD.

ANTECEDENTES: O Questionário de Atividades da Vida Diária (Activities of Daily Living Questionnaire, ADLQ, em inglês) tem como foco avaliar a capacidade de realizar atividades da vida diária (AVDs) com base na autopercepção de indivíduos com doença de Parkinson (DP). Uma versão do questionário em português do Brasil está disponível (ADLQ-Brasil), sendo necessárias mais investigações para avaliar suas propriedades de medidas. OBJETIVO: Investigar as validades de construto e concorrente da aplicação por telefone do ADLQ-Brasil com indivíduos da comunidade com DP. MéTODOS: Foram 50 adultos com DP (média de idade: 68 ± 9,5 anos) convidados a responder o ADLQ-Brasil em duas ocasiões aleatórias, presencialmente e por telefone, com intervalo de 7 a 10 dias. Instrumentos clínicos incluindo a Escala Unificada de Avaliação da Doença de Parkinson, o teste Timed Up and Go, o teste Nine Hole Peg, a versão reduzida do teste de equilíbrio Mini-Balance Evaluation Systems, a Escala de Apatia, o Inventário de Depressão de Beck, a Escala de Impacto de Fadiga Modificada e o Questionário de Qualidade de Vida na Doença de Parkinson foram aplicados na primeira sessão para estabelecer a validade de construto. RESULTADOS: Os escores totais do ADLQ-Brasil foram significativamente associados às medidas clínicas, fornecendo, assim, evidências de validade de construto. Não foram observadas diferenças significativas entre as pontuações médias obtidas entre a aplicação presencial e por telefone do questionário (IC95% = 0,997). Foi encontrado alto nível de concordância entre os escores totais do ADLQ-Brasil obtidos nas duas aplicações (IC95% = 0,994­0,998) e a maioria dos itens individuais apresentou, em média, concordância moderada. CONCLUSãO: Os achados fornecem suporte psicométrico para o ADLQ-Brasil como entrevista telefônica para avaliação do desempenho de AVDs em indivíduos com DP.

ACUTE CLINICAL OUTCOMES PREDICT BOTH GENERIC AND SPECIFIC HEALTH-RELATED QUALITY OF LIFE SIX AND 12 MONTHS AFTER STROKE: A ONE-YEAR PROSPECTIVE STUDY DEVELOPED IN A MIDDLE-INCOME COUNTRY.

OBJECTIVE: To identify acute predictors of generic and specific health-related quality of life (HRQoL) six and 12 months after stroke in individuals from a middle-income country. MATERIAL AND METHODS: This was a prospective study. The dependent outcomes assessed during six and 12 months after stroke included both generic and specific HRQoL (Short Form Health Survey-36 [SF-36] and stroke-specific quality of life [SSQOL]). The predictors were age, sex, education level, length of hospital stay, current living arrangement, stroke severity, functional independence, and motor impairment. RESULTS: 122 (59.9±14 years) and 103 (59.8±14.71 years) individuals were evaluated six and 12 months after stroke, respectively. Functional independence and sex were significant acute predictors of both generic and specific HRQoL. Functional independence was the strongest predictor (0.149≤R2≤0.262; 20.01≤F≤43.96, p<0.001), except for generic HRQoL at 12 months, where sex was the strongest predictor (R2=0.14; F=17.97, p<0.001). CONCLUSION: Generic and specific HRQoL in chronic individuals six and 12 months after stroke, from a middle-income country, can be predicted based on functional independence, the strongest predictor, assessed in the acute phase, except for generic HRQoL at 12 months. Functional independence can be modified by rehabilitation strategies and thus should be considered for HRQoL prognoses at chronic phase.

Barriers and facilitators to access post-stroke rehabilitation services in the first six months of recovery in Brazil.

PURPOSE: To identify barriers and facilitators to accessing post-stroke rehabilitation services six months after discharge from the stroke unit of a Brazilian public hospital. MATERIALS AND METHODS: This cross-sectional and descriptive study collected sociodemographic and clinical-functional data during hospitalization. Then, barriers and facilitators for accessing the post-stroke rehabilitation services were collected six months after discharge. We considered economic conditions and displacement, the quality and organization of post-stroke rehabilitation services, and personal conditions. RESULTS: A total of 174 patients were included. Among the 20 aspects analyzed, 17 (85.0%) were reported as facilitators, while three (15.0%) were as barriers. The identified barriers included financial income available for healthcare (49.4%), waiting time to schedule or to be seen (47.0%), and process to scheduling (45.4%). The main facilitators (> 79.0%) were the expectation of the patient with the treatment and assistance from family and friends. Moreover, most patients indicated as facilitators all aspects related to the quality of post-stroke rehabilitation services. CONCLUSION: Access to post-stroke rehabilitation services presented more facilitators than barriers. Public policies to subsidize health costs, optimize waiting time, and process for scheduling post-stroke rehabilitation services should be considered to reduce barriers. Likewise, human and financial resources must promote the facilitators.

Public policies to subsidize health costs, optimize waiting times and scheduling in post-stroke rehabilitation services should be considered to facilitate access to rehabilitation services for post-stroke patients.The involvement of family and friends in the treatment of post-stroke patients should be encouraged.Patients' motivation and positive expectations can facilitate access to post-stroke rehabilitation services.

Longitudinal associations between stroke-related neurologic deficits and course of basic activities of daily living up to six months after stroke.

PURPOSE: To investigate the course of basic activities of daily living (ADL) from admission up to six months after the stroke and the longitudinal associations between stroke-related neurological deficits at admission to the stroke unit and course of basic ADL. MATERIALS AND METHODS: 180 individuals with a first-ever stroke were assessed at admission to the stroke unit and at follow-ups of three and six months. Stroke-related neurological deficits were assessed at admission with the National Institutes of Stroke Scale (NIHSS). Independence in basic ADL was assessed at admission and three and six months after the stroke by the Modified Barthel Index (MBI). Generalized Estimating Equations (GEE) were performed. RESULTS: Dependence in basic ADL reduced overtime, with most changes occurring over the first three months. Individuals, who had moderate/severe stroke-related neurological deficits (NIHSS ≥6) at admission, had higher chances of becoming more dependent in activities related to feeding (OR:1.27;95%CI = 1.03-1.55;p = 0.021), bathing (OR:1.30;95%CI = 1.11-1.50;p = 0.0005), dressing (OR:1.19;95%CI = 1.04-1.36;p = 0.010), transfers (OR:1.24;95%CI = 1.05-1.46;p = 0.0072), stair climbing (OR:1.46;95%CI = 1.27-1.66;p < 0.0001), and ambulation (OR:1.21;95%CI = 1.02-1.43;p < 0.0001). CONCLUSIONS: Decreases in dependence in basic ADL occurred mainly over three months after the stroke and showed different patterns for specific ADL. Baseline moderate/severe stroke-related neurological deficits were associated with poor functional status in basic ADL over the follow-up period.

Stroke survivors experience dependence in basic activities of daily living (ADL) which is reduced over six months after the stroke and showed different individual variability in patterns of recovery.Patients with moderate/severe stroke-related neurological deficits had higher chances of becoming dependent in activities related to feeding, bathing, dressing, transfers, stair climbing, and ambulation.Rehabilitation professionals should consider assessing stroke-related neurologic deficits within the first hours after stroke, with particular attention to individuals with moderate/severe impairments.

Determinants of access to rehabilitation professionals by individuals with stroke in the first six months after hospital discharge in Brazil: a study based on the Andersen model.

BACKGROUND: determinants of access to rehabilitation professionals after stroke in middle-income countries, where the burden of this disease is higher, are little known. OBJECTIVES: To identify the determinants of access to rehabilitation professionals by individuals with stroke at one, three, and six months after hospital discharge in Brazil and compare referral and access rates after discharge. METHODS: Longitudinal and prospective study, with individuals with primary stroke, without previous disabilities. At hospital discharge, the number of rehabilitation professionals referred by the multidisciplinary team was recorded. The possible determinants of access, according to Andersen's model, were: a) predisposing factors: age, sex, education levels, and belief that they could improve with treatment; b) need factors: stroke severity, levels of disability; c) enabling factors: socioeconomic status, disposable income for health care, and quality of care provided by rehabilitation professionals. One, three, and six months after hospital discharge, individuals were contacted to identify which rehabilitation professionals were accessed. Multiple linear regression model and Wilcoxon tests were used (α=5%). RESULTS: 201 individuals were included. Disability levels and stroke severity explained 31%, 34%, and 39% (p<0.01) of access at one, three, and six months after hospital discharge, respectively. In all periods, there was less access than that recommended at the time of hospital discharge (p<0.01). CONCLUSION: Need factors (disability levels and stroke severity) were determinants of access in all assessed periods. In addition, in all periods, the comprehensiveness of care for individuals with stroke was compromised.

R3-Walk and R6-Walk, Simple Clinical Equations to Accurately Predict Independent Walking at 3 and 6 Months After Stroke: A Prospective, Cohort Study.

OBJECTIVE: To investigate if independent walking at 3 and 6 months poststroke can be accurately predicted within the first 72 hours, based on simple clinical bedside tests. DESIGN: Prospective observational cohort study with 3-time measurements: immediately after stroke, and 3 and 6 months poststroke. SETTING: Public hospital. PARTICIPANTS: Adults with first-ever stroke evaluated at 3 (N=263) and 6 (N=212) months poststroke. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: The outcome of interest was independent walking at 3 and 6 months after stroke. Predictors were age, walking ability, lower limb strength, motor recovery, spatial neglect, continence, and independence in activities of daily living. RESULTS: The equation for predicting walking 3 months poststroke was 3.040 + (0.283 × FAC baseline) + (0.021 × Modified Barthel Index), and for predicting walking 6 months poststroke was 3.644 + (-0.014 × age) + (0.014 × Modified Barthel Index). For walking ability 3 months after stroke, sensitivity was classified as high (91%; 95% CI: 81-96), specificity was moderate (57%; 95% CI: 45-69), positive predictive value was high (76%; 95% CI: 64-86), and negative predictive value was high (80%; 95% CI: 60-93). For walking ability 6 months after stroke, sensitivity was classified as moderate (54%; 95% CI: 47-61), specificity was high (81%; 95% CI: 61-92), positive predictive value was high (87%; 95% CI: 70-96), and negative predictive value was low (42%; 95% CI: 50-73). CONCLUSIONS: This study provided 2 simple equations that predict walking ability 3 and 6 months after stroke. This represents an important step to accurately identify individuals, who are at high risk of walking dependence early after stroke.

Predicting self-perceived manual ability at three and six months after stroke: A prospective longitudinal study.

BACKGROUND: Recovery of manual ability is a critical issue in rehabilitation. Currently, little is known regarding the baseline predictors of self-perceived manual ability, which could capture information on individual's perceived functional ability, especially in carrying-out routine tasks outside clinical settings. OBJECTIVE: To identify baseline predictors, which can be easily obtained within clinical settings, of self-perceived manual ability at three and six months after discharge from a stroke unit. METHODS: A 6-month longitudinal study was carried-out. Participants were recruited from a stroke unit of a public hospital. The dependent outcome was self-perceived manual ability, and the following predictors were investigated: age, stroke severity, upper-limb motor impairments, cognitive function, muscle strength, and functional capacity. Linear regression analyses were employed to identify multivariate predictors of manual ability at three and six months after discharge (α=5%). RESULTS: Participated 131 individuals, 69 women (mean age of 60 years). Regression analyses revealed that stroke severity and age accounted for 31% and 47% of the variance in manual ability at three and six months after stroke, respectively. Stroke severity was the best predictor of manual ability at three (R2=29%; F=44.7; p<0.0001) and six months (R2=45%; F=88.2; p<0.0001) after stroke, respectively. CONCLUSION: Stroke severity showed to be the best predictor of manual ability at both three and six months after stroke. Although significant, age added little to the explained variance.

Balance deficit is the domain of the Fugl-Meyer scale that best explain limitations in functional independence during hospitalization after a stroke.

PURPOSE: To investigate which of the residual sensorimotor impairments, assessed by the Fugl-Meyer scale, would best explain functional independence during hospitalization after a stroke. METHODS: This cross-sectional study retrieved data from medical records between January 2014 to December 2021. Explanatory independent variables were the following domains of the Fugl-Meyer scale: joint pain, joint range of motion, balance, sensory function, and motor function of the upper and lower limbs. Functional independence was measured by the Functional Independence Measure (FIM). Step-wise multiple linear regression analysis was used to identify which measures would explain functional independence (α=5%). RESULTS: Data from 1,344 individuals, who had a mean age of 64 years, were retrieved. All included explanatory variables were significantly correlated with the FIM scores (0.24 ≤ r ≤ 0.87). Balance alone explained 76 % (F=4.24; p<0.001) of the variance in the FIM scores. When sensory function and upper-limb motor function scores were included in the model, the explained variance increased to 82 % (F = 1.935; p < 0.001). CONCLUSIONS: Balance, which is important for carrying-out self-care activities, is the domain of the Fugl-Meyer scale that best explained functional independence during hospitalization after a stroke. Although sensory function and motor function of the upper limb added little to the explained variance, they should not be underlooked. Future research is needed to determine whether progressive balance training interventions would enhance functional independence after a stroke.

Changes in the clinico-functional characteristics of stroke patients in the acute phase during the COVID-19 pandemic.

OBJECTIVE: To compare the sociodemographic and clinico-functional characteristics of patients admitted to a stroke unit immediately before and during two different COVID-19 pandemic phases. METHODS: This exploratory study was conducted in the stroke unit of a public hospital in Brazil. Patients consecutively admitted to a stroke unit for 18 months with primary stroke aged ≥20 years were included and divided into three groups: G1: Pre-pandemic; G2: Early pandemic; and G3: Late pandemic. The sociodemographic and clinico-functional characteristics of the groups were compared (α=0.05). RESULTS: The study included 383 individuals (G1=124; G2=151; G3=108). The number of risk factors (higher in G2; p≤0.001), smoking (more common in G2; p≤0.01), type of stroke (ischemic more common in G3; p=0.002), stroke severity (more severe in G2; p=0.02), and level of disability (more severe in G2: p≤0.01) were significantly different among the groups. CONCLUSION: A greater number of serious events and risk factors including smoking and higher level of disability was observed in patients in the beginning of the pandemic than in the late phases. Only the occurrence of ischemic stroke increased in the late phase. Therefore, these individuals may have an increased need for rehabilitation services monitoring and care during their lifespan. Additionally, these results indicate that health promotion and prevention services should be strengthened for future health emergencies.

Access to rehabilitation professionals by individuals with stroke one month after hospital discharge from a stroke unit in Brazil is insufficient regardless of the pandemic.

OBJECTIVE: To compare access to rehabilitation professionals by individuals with stroke one month after hospital discharge from a stroke unit in Brazil, before and during the COVID-19 pandemic. MATERIALS AND METHODS: This longitudinal and prospective study included individuals aged 20 years or older without previous disabilities admitted into a stroke unit due to a first stroke. Individuals were divided into two groups: before (G1) and during (G2) the COVID-19 pandemic. Groups were matched for age, sex, education level, socioeconomic status, and stroke severity. One month after hospital discharge, individuals were contacted via telephone to collect data regarding their access to rehabilitation services based on the number of referred rehabilitation professionals. Then, between-group comparisons were conducted (α = 5%). RESULTS: The access to rehabilitation professionals was similar between groups. Rehabilitation professionals accessed included medical doctors, occupational therapists, physical therapists, and speech therapists. The first consultation after hospital discharge was mainly provided by public services. Despite the pandemic, telehealth was not frequent in any period evaluated. In both groups, the number of accessed professionals (G1 = 110 and G2 = 90) was significantly lower than the number of referrals (G1 = 212 and G2 = 194; p < 0.001). CONCLUSIONS: Access to rehabilitation professionals was similar between groups. However, the number of accessed rehabilitation professionals was lower than that of referred ones during both periods. This finding indicates a compromised comprehensiveness of care for individuals with stroke, regardless of the pandemic.

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.

Predictors of access to healthcare services within 1 month after stroke in a developing country: A longitudinal prospective study.

BACKGROUND: Globally, people with disabilities face difficulties accessing care, resulting in worse health outcomes and higher healthcare costs. However, information regarding access to healthcare services for stroke survivors in developing countries is scarce. OBJECTIVE: To identify predictors of access to healthcare services within 1 month of hospital discharge in a developing country (Brazil). METHODS: For six months, individuals from a stroke unit, aged ≥20 years, after their first stroke and without previous disability, were included and evaluated at hospital discharge for socio-demographic (sex, age, education, and socio-economic level) and clinical-functional (severity of stroke and level of disability) characteristics. The number and type of referrals to healthcare services provided by hospital staff were also recorded. One month after hospital discharge, data regarding access to healthcare services obtained by the subjects were collected. The Wilcoxon test was used to compare the number of referrals and access to healthcare services obtained by the subjects. To identify the predictors of access, a binary logistic regression was used (α = 5%). RESULTS: A total of 78 individuals were evaluated one month after hospital discharge, all with at least one referral. The total access to healthcare services within 1 month of stroke was significantly lower than the total number of referrals (p < 0.001). Sex (odds ratios (OR) = 18.92; p = 0.01) and educational level (OR = 1.48; p = 0.04) were significant predictors of access. CONCLUSIONS: Being female and having low education levels were predictors of access to healthcare services within 1 month of stroke in a developing country. In addition, the access was below expectations, compromising the integrality of care and national and international recommendations, which is a concern given the need for early care to obtain better results in health and functional outcomes.

Oxygen uptake efficiency slope in community-dwelling ambulant stroke survivors during walking and stair climbing: a cross-sectional study.

BACKGROUND: Oxygen uptake efficiency slope during submaximal tests has been proposed as a more appropriate measure of aerobic capacity after suffering a stroke, since some individuals cannot tolerate maximal exercise testing. However, it has not yet been investigated whether the oxygen uptake efficiency slope is able to differentiate between healthy individuals and those who have suffered a stroke. OBJECTIVES: To compare the oxygen uptake efficiency slope during walking and stair climbing between stroke survivors and age- and sex-matched healthy controls. METHODS: This is a cross-sectional study in which 18 individuals who had suffered a stroke (stroke survivors) and 18 healthy controls matched for sex and age were included. Oxygen consumption and minute ventilation were collected breath-by-breath during walking (6-min Walk Test) and stair climbing. The oxygen uptake efficiency slope was estimated by the slope of the line obtained through linear regression. RESULTS: The stroke survivors had a lower oxygen uptake efficiency slope during the 6-min Walk Test than the healthy controls (MD 498, 95% CI 122 to 873, p = .01). The between-group difference for the Stair Test was smaller and not statistically significant (MD 349, 95%CI -73 to 772, p = .10). CONCLUSIONS: Stroke survivors had lower oxygen uptake efficiency slope during the performance of the 6-min Walk Test when compared to sex- and age-matched healthy controls. This suggests that stroke survivors have worse cardiopulmonary capacity.

Measurement properties of the Brazilian version of the Stroke Upper Limb Capacity Scale (SULCS-Brazil).

BACKGROUND: The Stroke Upper Limb Capacity Scale (SULCS) is a clinically useful measure of upper-limb (UL) capacity, which assesses both basic and advanced capacities. OBJECTIVES: To examine the reliability, construct validity, and interpretability of the SULCS-Brazil with community-dwelling individuals with stroke. METHODS: The SULCS-Brazil and measures of impairment (handgrip strength and motor function of the paretic UL), capacity (manual and digital dexterities), and performance were applied during the first session, to establish construct validity (80 patients). The SULCS-Brazil was applied again during a second session (a sub-set of 30 patients), to investigate test-retest reliability. Test-retest reliability was evaluated using kappa statistics (k) for the individual items, intraclass correlation coefficient (ICC) for the total scores, standard error of measurement (SEM), minimal detectable change (MDC), and Bland-Altman plot. For the evaluation of construct validity, pre-defined hypotheses were created to estimate the strength of the correlations between the SULCS-Brazil scores and established measures of UL function, using Spearman correlation coefficients. Interpretability was investigated by evaluating both ceiling/ floor effects. RESULTS: High level of agreement was found between the SUCLS-Brazil total scores obtained on both applications (ICC = 0.98; 95%CI:0.96-0.99) and 80% of the individual items had almost perfect agreement (k= 0.81-1.0). The SEM (0.46) and the MDC (1.27) showed clinically acceptable values. All pre-defined hypotheses were confirmed, indicating adequate construct validity of the SULCS-Brazil. No significant ceiling/floor effects were observed. CONCLUSIONS: The SULCS-Brazil showed to be reliable and valid for the evaluation of upper-limb capacity of individuals with stroke.

Functional independence measured in the acute phase of stroke predicts both generic and specific health-related quality of life: a 3-month prospective study in a middle-income country.

PURPOSE: To identify acute predictors of both generic and specific health-related quality of life (HRQoL) 3 months after stroke in individuals from a middle-income country. MATERIALS AND METHODS: A 3-month prospective study with individuals who had suffered their first stroke, without previous disability, discharged from a stroke unit. The dependent outcomes, assessed 3 months after stroke, were generic and specific HRQoL (SF-36 and SSQOL total scores, respectively). The predictors assessed in the stroke unit were age, sex, education level, duration of hospital stay, current living arrangement, stroke severity (National Institutes of Health Stroke Scale-NIHSS), functional independence (Modified Barthel Index-MBI), motor impairment (Fugl-Meyer Assessment), and lower- and upper-limb residual muscle strength deficits. Linear multiple regression analyses were employed to identify predictors of both generic (model-1) and specific (model-2) HRQoL (α = 5%). RESULTS: One hundred twenty-six individuals were assessed at 3-month post-stroke (61.3 ± 13.6 years). Regression analysis showed that functional independence was the best predictor of both generic (R2 = 21%; F = 34.82; p < 0.001) and specific (R2 = 29%; F = 51.71; p < 0.001) HRQoL at 3-month post-stroke. CONCLUSION: Both generic and specific HRQoL at 3-month post-stroke can be predicted by functional independence assessed in the acute phase with the MBI.

Health-related quality of life (HRQoL), a patient-centered outcome, is essential for healthcare, mainly in stroke, a chronic disease with a broad spectrum of disabilities.Functional independence is a key outcome and should always be a part of characterizing patients before the rehabilitation process.Functional independence assessed with the Modified Barthel Index in the acute phase of stroke predicts both generic and specific HRQoL at 3-month post-stroke.Patients post-stroke with lower functional independence at hospital discharge may be at risk of having lower HRQoL at 3-month post-stroke.

Changes in the clinico-functional characteristics of stroke patients in the acute phase during the COVID-19 pandemic

ABSTRACT Objective To compare the sociodemographic and clinico-functional characteristics of patients admitted to a stroke unit immediately before and during two different COVID-19 pandemic phases. Methods This exploratory study was conducted in the stroke unit of a public hospital in Brazil. Patients consecutively admitted to a stroke unit for 18 months with primary stroke aged ≥20 years were included and divided into three groups: G1: Pre-pandemic; G2: Early pandemic; and G3: Late pandemic. The sociodemographic and clinico-functional characteristics of the groups were compared (α=0.05). Results The study included 383 individuals (G1=124; G2=151; G3=108). The number of risk factors (higher in G2; p≤0.001), smoking (more common in G2; p≤0.01), type of stroke (ischemic more common in G3; p=0.002), stroke severity (more severe in G2; p=0.02), and level of disability (more severe in G2: p≤0.01) were significantly different among the groups. Conclusion A greater number of serious events and risk factors including smoking and higher level of disability was observed in patients in the beginning of the pandemic than in the late phases. Only the occurrence of ischemic stroke increased in the late phase. Therefore, these individuals may have an increased need for rehabilitation services monitoring and care during their lifespan. Additionally, these results indicate that health promotion and prevention services should be strengthened for future health emergencies.

Habitual walking speed and fatigue explain self-reported functional capacity after stroke.

INTRODUCTION: Individuals after stroke present several motor impairments, which reduced the functional capacity. The understanding of modifiable factors which are related to functional capacity in individuals with chronic stroke could better direct clinical practice. However, the mechanisms that could influence functional capacity in individuals with chronic stroke are not fully understood. OBJECTIVE: This study aimed to determine which modifiable variables would best predict self-reported functional capacity after stroke. DESIGN: Cross-sectional. SETTING: Research laboratory setting. PARTICIPANTS: Ninety two individuals 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. MAIN OUTCOME MEASURES: 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. RESULTS: 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%. CONCLUSIONS: Habitual walking speed and fatigue were significant predictors of self-reported functional capacity in individuals with chronic stroke. These individuals may increase their functional capacity with interventions aimed at increasing walking speed and reducing fatigue.

Test-retest reliability and measurement error of the modified gait efficacy scale in individuals with stroke.

PURPOSE: To investigate the test-retest reliability and measurement error of the Brazilian version of the modified Gait Efficacy scale (mGES-Brazil) in individuals who have had stroke. METHODS: The mGES-Brazil was applied on two occasions, five to seven days apart, in a research laboratory setting. Test-retest reliability and measurement error, which included the standard error of measurement (SEM), smallest detectable change (SDC), and analysis of the limits of agreement by the Bland-Altman plots, were examined. RESULTS: Fifty individuals who have had stroke (18 men), with a mean age of 64 ± 11 years, were evaluated. All individual items showed good reliability (Intra-class Correlation Coefficient - ICC2,1 > 0.90). The ICC was 0.98 (95% CI 0.97 to 0.99) and the Bland and Altman plots revealed no systematic changes in the mean test-retest scores. The SEM (SEM%) was 3 (5%), within the recommended values, while the SDC was 8 points. CONCLUSION: The mGES-Brazil demonstrated to be reliable to be applied within clinical and research contexts for the assessment of changes in walking confidence of individuals who have had stroke. Changes in mGES scores ≥8 points reflect real changes.

Cross-cultural adaptation of the Activities of Daily Living Questionnaire-Brazil in Parkinson's disease.

BACKGROUND: Culturally adapted measures to assess the performance of activities of daily living (ADL) in individuals with Parkinson's disease (PD) are limited in Brazil. OBJECTIVE: To adapt the ADL Questionnaire to the Brazilian culture and to analyze its reproducibility in individuals with PD. METHODS: The ADL Questionnaire was translated and cross-culturally adapted to Brazilian Portuguese language. Reproducibility was analyzed using test-retest reliability and agreement values. The test-retest reliability of the individual items and total scores were calculated. The limits of agreement were verified using the Bland-Altman plot. The standard error of measurement (SEM) and the minimum detectable change (MDC) were calculated. Patients who were classified on a score of 1-4 on the modified Hoehn and Yahr scale were eligible. RESULTS: No divergence was identified between the original and the adapted version, which demonstrated adequate semantic and conceptual equivalence. The Bland-Altman plot showed no systematic changes in the mean test-retest scores. The intraclass correlation coefficient (ICC) was 0.98 (95% confidence interval [95%CI] 0.93-0.99), and all individual items showed good levels of reliability (>0.60). The SEM (SEM%) and MDC (MDC%) values were 3.0 (6.75%) and 8.2 (18.7%), respectively. These values are within the recommended values. CONCLUSIONS: The ADL-Brazil Questionnaire is a reliable instrument to be used for clinical and research purposes to assess self-perceptions of ADL performance in individuals with PD.
