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.

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.

Telephone-based assessment of the fear of falling in older people and factors associated.

This study aimed to validate the telephone-based application of the Falls Efficacy Scale-International (FES-I) for the assessment of the fear of falling in older people, and to investigate, among personal and environmental factors, which ones can explain this fear in this population. Participants answered the FES-I on two randomized occasions, face-to-face and by telephone. Intraclass correlation coefficient (ICC 3,1 ) was used to investigate the levels of agreement between the two occasions. The possible factors associated were sex, age, previous history of falls, family arrangement, practice of physical activity, presence of orthopedic pathologies, use of walking aids, presence of visual impairment, and presence of stairs in the home environment. Linear regression analysis was applied to investigate which of these factors could explain the fear of falling in older people. One hundred twenty-two individuals were included. There was no significant difference in the mean difference obtained between the two applications of the FES-I (1 point; 95% confidence interval, -4 to 6), with a high level of agreement (ICC = 0.88). Sex and presence of orthopedic pathologies explained 14% of the model. The FES-I showed to be a reliable scale to be applied for telephone assessments of fear of falling in older people. In addition, women with orthopedic pathologies are the profile of older people with most afraid of falling.

Home-Based Interventions may Increase Recruitment, Adherence, and Measurement of outcomes in Clinical Trials of Stroke Rehabilitation.

OBJECTIVE: This study aimed to investigate the completion rates of a home-based randomized trial, which examined home-based high-intensity respiratory muscle training after stroke compared with sham intervention. MATERIALS AND METHODS: Completion was examined in terms of recruitment (enrolment and retention), intervention (adherence and delivery of home-visits) and measurement (collection of outcomes). RESULTS: Enrolment was 32% and retention was 97% at post-intervention and 84% at follow-up. Adherence to the intervention was high at 87%. Furthermore, 83% of planned home-visits were conducted and 100% of outcomes were collected from those attending measurement sessions. CONCLUSION: This home-based randomized trial demonstrated high rates of enrolment, retention, adherence, delivery of home-visits, and collection of outcomes. Home-based interventions may help to improve completion rates of randomized trials.

Using a cane for one month does not improve walking or social participation in chronic stroke: An attention-controlled randomized trial.

OBJECTIVE: To examine the effects of the provision of a cane, delivered to ambulatory people with chronic stroke, for improving walking and social participation. DESIGN: Two-arm, randomized trial. SETTING: Community-based. PARTICIPANTS: Ambulatory individuals with chronic stroke. INTERVENTIONS: The experimental intervention was the provision of a single-point cane during one month. The control group received a placebo intervention. OUTCOME MEASURES: Walking speed, step length, cadence, walking capacity, and walking confidence were measured without the cane to examine its rehabilitative effect. Walking speed was also measured with the cane for inclusiveness, and social participation was measured for examining carry over effects. Outcomes were measured at baseline, and after one and two months. RESULTS: Fifty individuals were included. In the experimental group, mean age was 69 years (SD 14), and walking speed was 0.58 m/s (SD 0.17). In the control group, mean age was 68 years (SD 13), and walking speed was 0.63 m/s (SD 0.15). When walking without the cane, after one and after two months, there were no between-group differences in any measures. When walking with the cane, after one month, the experimental group walked 0.14 m/s (95% CI 0.05-0.23) faster than the control group and after two months, they were still walking 0.18 m/s (95% CI 0.06-0.30) faster. CONCLUSION: Use of a cane improved walking speed, only when participants walked with the cane. Use of cane for one month did not improve walking outcomes, when walking without the cane. People with stroke would need to continue to use the cane to maintain any benefits in walking speed.

Efeitos do treino de equilíbrio na velocidade de marcha, mobilidade e qualidade de vida de indivíduos pós acidente vascular encefálico / Effects of the balance training on walking speed, mobility and quality of life of stroke survivors

Introdução: O objetivo do presente estudo foi realizar uma revisão sistemática da literatura investigando os efeitos do treino de equilíbrio na velocidade de marcha, mobilidade e qualidade de vida de indivíduos hemiparéticos. Métodos: Foram realizadas buscas nas bases de dados Medline, Cinahl, Web of Science, Lilacs e PEDro, sem restrição em relação ao idioma e ano de publicação do estudo. Os artigos foram avaliados pelo título, resumo e posteriormente pelo texto completo e, enfim, selecionados em relação à elegibilidade por dois autores independentes. A qualidade metodológica dos estudos experimentais incluídos foi avaliada de acordo com a escala PEDro. Resultados: Oito artigos foram incluídos na presente revisão. A descrição dos resultados sugere que o treino de equilíbrio pode ser eficaz para aumentar a velocidade de marcha e melhorar a mobilidade de indivíduos hemiparéticos. Embora esses resultados sejam promissores, os estudos apresentam uma qualidade metodológica entre moderada a baixa. Além disso, os efeitos na participação social/qualidade de vida ainda são inconclusivos, uma vez que apenas um estudo avaliou essa variável. Conclusão: O treino de equilíbrio parece melhorar a velocidade de marcha e mobilidade de indivíduos hemiparéticos, porém o efeito na participação social ainda deve ser melhor investigado. (AU)

Introduction: The aim of this systematic literature review was to investigate the effects of balance training on walking speed, mobility and social participation/quality of life of hemiparetic individuals. Methods: Searches were conducted on Medline, Cinahl, Web of Science, Lilacs and PEDro databases, without restriction regarding the language and year of publication. The articles were evaluated by title, abstract and full text and, finally, selected in relation to the eligibility by two independent authors. The methodological quality of the included experimental studies was evaluated according to the PEDro scale. Results: Eight articles were included in the present review. The description of the results suggests that balance training may be effective in increasing walking speed and improving the mobility of hemiparetic individuals. Although these results are promising, the studies show a moderate to low methodological quality. The effects on social participation/quality of life are still inconclusive, since only one study evaluated this variable. Conclusion: Balance training seems to improve walking speed and mobility of hemiparetic individuals, but the effect on social participation should still be better investigated. (AU)

Benefits of Home-Based Respiratory Muscle Training from the Perspectives of Individuals Who Had a Stroke: Qualitative Study.

BACKGROUND: 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. OBJECTIVE: To understand how individuals 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. DESIGN: Qualitative study. SETTING: Community-dwelling patients. PATIENTS: Fifteen individuals who had a stroke. METHODS: 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. RESULTS: 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. CONCLUSION: Individuals who had experienced a stroke perceived the benefits of high-intensity home-based respiratory muscle training in all components of function.

Deficits in motor coordination of the paretic lower limb limit the ability to immediately increase walking speed in individuals with chronic stroke.

OBJECTIVE: To explore the relationships between clinical measures and the ability to increase walking speed in ambulatory people with chronic stroke and to identify which measures would best predict walking speed reserve. METHODS: An exploratory, cross-sectional study was conducted with 114 individuals with chronic stroke. The outcome of interest was walking speed reserve, defined as the difference between individuals' comfortable and maximal walking speeds. Predictors were characteristics of the participants (age, sex, time since stroke, relative lower-limb dominance) and motor impairments (tonus, strength, and motor coordination). RESULTS: The characteristics of the participants did not significantly correlate with walking speed reserve. All measures of motor impairments, i.e., tonus, strength, and motor coordination, were significantly correlated with walking speed reserve (p < 0.01), but only motor coordination was kept in the regression model. Motor coordination alone explained 35% (F = 61.5; p < 0.001) of the variance in walking speed reserve. CONCLUSIONS: The level of motor coordination of the paretic lower limb is associated with the walking speed reserve of individuals with stroke. Interventions aimed at improving motor coordination may have the potential to improve everyday situations that require immediate increases in walking speed.

Efeitos do fortalecimento muscular do assoalho pélvico em pacientes pós-acidente vascular encefálico com incontinência urinária / Effects of pelvic floor muscle strengthening in post-stroke patients with urinary incontinence

Introdução: Pacientes pós-acidente vascular encefálico (AVE) apresentam alterações motoras, causando perda de força muscular, que afeta inclusive os músculos do assoalho pélvico. Essa perda de força pode levar a incontinência urinária que consiste na perda involuntária de urina. A Sociedade Internacional de Incontinência Urinária (SIC) indicou a fisioterapia como tratamento de primeira linha para a incontinência urinária, mas ainda não foram encontradas revisões sistemáticas da literatura que avalie o efeito do fortalecimento muscular do assoalho pélvico em pacientes pós-AVE com IU. Objetivo: Realizar uma revisão sistemática da literatura sobre os efeitos do fortalecimento do assoalho pélvico em pacientes pós-AVE com IU. Métodos: Buscas nas bases Medline, Lilacs, Scielo, PEDro, sem restrição de data ou idioma de publicação. Foram utilizadas combinações de palavras-chave, tais como: acidente vascular encefálico, reabilitação, incontinência urinária, fisioterapia, assoalho pélvico, além de seus respectivos termos em inglês. Os estudos foram analisados por dois avaliadores independentes. A qualidade metodológica dos estudos incluídos foi avaliada de acordo com a escala PEDro. Resultados: A estratégia de busca resultou em 693 artigos, e após a análise de títulos, resumos e textos completos, realizados por dois avaliadores independentes, foram excluídos 688, restando cinco artigos selecionados para a presente revisão sistemática. Em geral, os estudos mostraram que os pacientes pós-AVE obtiveram melhora em todas as medidas de desfecho investigadas (força, resistência e atividade dos músculos do assoalho pélvico, frequência de micção, número de episódios de incontinência, número de absorventes usados, quantidade da perda de urina, função do trato urinário inferior, sintomas da bexiga hiperativa e independência funcional), exceto na qualidade de vida e impacto da incontinência, tanto a curto como a longo prazo. Conclusão: Os resultados parecem promissores em relação à eficácia do fortalecimento muscular do assoalho pélvico como uma intervenção para a reabilitação de indivíduos com IU pós-AVE. No entanto, tais conclusões se baseiam em apenas cinco estudos, de qualidade metodológica moderada, necessitando de mais estudos sobre o assunto. (AU)

Introduction: Post-stroke patients present motor impairments, such as muscle weakness, which also affects the pelvic floor muscles. This loss of strength can lead to urinary incontinence (UI), which consists of involuntary loss of urine. The International Society for Urinary Incontinence has indicated physical therapy as a first-line treatment for UI, but no systematic reviews of the literature have yet found that evaluates the effects of pelvic floor muscle training in post-stroke patients with UI. Objective: To perform a systematic review of the literature investigating the effects of pelvic floor strengthening in post-stroke patients with UI. Methods: Searches in Medline, Lilacs, Scielo, PEDro, without restriction of date or language of publication were performed. The terms included the following descriptors: stroke, rehabilitation, urinary incontinence, physical therapy, pelvic floor, as well as these terms in Portuguese, with strategies specific to each base. The studies were analyzed by two independent evaluators. The methodological quality of the included studies was evaluated according to the PEDro scale. Results: The search strategy resulted in 693 articles, and after the analysis of titles, abstracts and full texts, 688 were excluded, resulting in five articles selected for the present systematic review. In general, studies have shown that post-stroke patients improved all investigated outcome measures (strength, endurance and pelvic floor muscle activity, urinary frequency, number of incontinence episodes, number of absorbents used, amount of loss of urine, lower urinary tract function, overactive bladder symptoms and functional independence), except for the quality of life and impact of incontinence, both short-term and long-term. Conclusion: As observed, the results seem promising regarding the efficacy of pelvic floor muscle training as an intervention for the rehabilitation of individuals with UI post-stroke. However, these conclusions are based on only five studies, of moderate methodological quality, requiring further studies. (AU)

Measurement properties of the lower extremity motor coordination test in individuals with stroke.

OBJECTIVES: To evaluate the construct validity, inter- and intra-rater reliabilities, best scoring method and testing methods (direct vs video observations), and to determine the smallest real difference (SRD) and standard error of the measurement (SEM) of the lower Extremity Motor Coordination Test (LEMOCOT). DESIGN: Methodological study. SUBJECTS: Thirty-six stroke subjects. METHODS: Outcomes include measures of motor recovery, muscular tone, strength, motor coordination, foot tactile sensation, and gait speed. RESULTS: The LEMOCOT scores were able to discriminate between stroke individuals from those predicted for healthy subjects, between the paretic and non-paretic limbs for both the sub-acute and chronic groups and differentiated between individuals with different functional levels and degrees of motor recovery. For the intra- and inter-rater reliabilities, very high and significant coefficients were found for both the paretic and non-paretic lower limbs for both groups (intra-class correlation coefficients (ICC) > 0.97, p < 0.0001). Significant differences were found regarding all scoring methods (18.91 < F < 27.49, p < 0.0001), but they were not clinically important and all showed adequate test-retest reliability and acceptable SRD and SEM (< 15%) values. There was also agreement between the scores from the direct and video observations. CONCLUSION: The LEMOCOT demonstrated adequate measurement properties in stroke subjects and, therefore, could be an appropriate measure for research and clinical purposes.
