RESUMEN

BACKGROUND: Fatigue is a common symptom in patients with multiple sclerosis and it can lead to activity limitations. Thus, it is important to analyze the relationship between fatigue and activity outcomes, such as walking speed and mobility. OBJECTIVES: To investigate the relationship between fatigue and walking speed and mobility in individuals with multiple sclerosis. METHODS: A cross-sectional study was performed. Adults with multiple sclerosis, without cognitive impairments and who were able to walk were recruited. Fatigue was assessed with the Modified Fatigue Impact Scale (MFIS). Walking speed, usual and fast, was assessed with the 10-meter Walk Test (10MWT), and mobility with the Timed Up and Go Test (TUG). Pearson correlation analysis was performed. A significance level of 5 % was used. RESULTS: Thirty participants were included, most of the relapsing-remitting multiple sclerosis (n = 24, 80 %). A mean age of 41 (11) years and the median Expanded Disability Status Scale (EDSS) score was 2.65 (2.18) points. Mean MFIS score was 41.87 ± 19.42 points, mean usual walking speed was 1.02 ± 0.28 m/s, mean fast walking speed was 1.55 ± 0.48 m/s, and the mean total time in the TUG was 10.07 ± 3.05 s. A significant negative correlation of moderate magnitude was found between fatigue and usual walking speed (r=₋0.51, p < 0.05). A significant negative correlation of moderate magnitude was found between fatigue and fast walking speed (r=₋0.54, p < 0.05). A significant, positive correlation of moderate magnitude was found between fatigue and mobility (r = 0.54, p < 0.05). CONCLUSION: There was a correlation between fatigue and walking speed and mobility in individuals with multiple sclerosis. These results highlight the need to assess fatigue in individuals with multiple sclerosis, since the presence of fatigue is associated with reduced walking speed and mobility.

RESUMEN

BACKGROUND: Fatigue is one of the most common symptoms reported by individuals with multiple sclerosis and it contributes to the reduction of the functionality. Therefore, it is important to assess the impact of fatigue on daily living of individuals with multiple sclerosis. The Modified Fatigue Impact Scale (MFIS) is an instrument to assess the perception of the impact of fatigue. However, there have been no investigations about the measurement properties of this instrument administered over the telephone for individuals with multiple sclerosis. OBJECTIVES: To verify the concurrent validity, the test-retest reliability, the standard error of measurement (SEM) and the minimal detectable change (MDC) of the MFIS applied over the telephone to assess the perception of the impact of fatigue of individuals with multiple sclerosis. METHODS: The MFIS, composed of 21 items covering three domains: physical, cognitive and psychosocial, was applied at three different moments with an interval of 5-7 days. To establish the concurrent criterion validity, the face-to-face application and the first evaluation by telephone were used. The two telephone assessments were used to assess the test-retest reliability The intraclass correlation coefficient (ICC) with 95 % confidence interval (CI) and the Bland-Altman method were used. The standard error of measurement (SEM) and the MDC was calculated according to reliability results. RESULTS: Thirty individuals (40.83 ± 10.61, 60 % female) were included. The median score on the Expanded Disability Status Scale was 2.00 (±4.00). The majority of participants experienced fatigue (n = 17; 56.67 %). A significant and high magnitude correlation (0.70 ≤ ICC ≤ 0.87, p < 0.001) was found in the investigation of concurrent criterion validity. The Bland-Altman method showed a mean difference between 0.70 to 2.17 points between face-to-face and telephone-based application of the MFIS. For test-retest reliability, a significant and very high magnitude correlation (0.91 ≤ ICC ≤ 0.97, p < 0.001) was found. The Bland-Altman method showed a mean difference between -0.03 and -0.77 points between two telephone-based applications. The SEM and the MDC were 0.71 and 1.97 points. CONCLUSION: The telephone-based application of the MFIS to assess the perceived impact of fatigue in individuals with multiple sclerosis demonstrated adequate measurement properties, and may be a valuable tool to assess patients in clinical practice.

RESUMEN

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.

RESUMEN

OBJECTIVES: To identify the factors affecting the use of physiotherapy services among individuals with Parkinson's disease (PD) living in Brazil. METHODS: Overall, 479 individuals with idiopathic PD, of both sexes, at any stage of the Hoehn & Yahr (HY) scale, and from seven capital cities in Brazil were recruited from 2014 to 2016. Multivariate logistic regression was the main statistical tool. For the construction of the logistic model, the association of the dependent variable "physiotherapy" with the independent sociodemographic/economic and clinical variables: age, education, family income, time of PD since onset, HY, the activities of daily living and motor subscales of the Unified Parkinson's Disease Rating Scale, cognitive aspects, depressive symptoms, fear of falling, freezing gait, history of falls, physical activity level, gait speed, walking performance and balance, were verified. RESULTS: The 479 individuals had an average age of 65.2 ± 11.0 years, 88% were in the HY I-III stages and 43.4% were under physiotherapy treatment. The analysis identified two determinant variables related to the use of the physiotherapy service: level of education (OR = 1.24) and walking performance (OR = 0.82). Decreased walking performance and a higher educational level increased the use of a physiotherapy service in individuals with PD living in Brazil. CONCLUSIONS: The present study shows that individuals with PD, residents from different regions of Brazil, have limited access to physiotherapy services. In addition, the Brazilian Public Health Care System, as well as local programs, need to target PD individuals with a low educational level to improve their access to physiotherapy services. Goals should aim towards the development of physical exercise programs to improve the patients' functional performance for a longer period.

RESUMO Descrever a utilização do serviço de fisioterapia e identificar os fatores que determinam o uso desse serviço entre indivíduos com doença de Parkinson (DP) que vivem no Brasil. Métodos: No total, 479 indivíduos com DP idiopática, de ambos os sexos, em qualquer estágio da escala de Hoehn & Yahr (HY) e de sete capitais do Brasil foram recrutados durante 2014 a 2016. A análise de regressão logística multivariada foi a principal ferramenta de análise estatística. Para a construção do modelo logístico foi investigada a associação da variável dependente "fisioterapia" com variáveis independentes sociodemográficas, econômicas e clínicas: idade, educação, renda familiar, tempo de DP desde o início, HY, domínio motor e atividade de vida diária da Unified Parkinson´s Disease Rating Scale, aspectos cognitivos, sintomas depressivos, medo de queda, congelamento marcha, história de quedas, nível de atividade física, velocidade de marcha, capacidade de caminhar e equilíbrio. Resultados: 479 indivíduos apresentaram média de 65,2 ± 11,0 anos, 88% tiveram HY = I-III e 43,4% faziam fisioterapia para a DP. A análise identificou duas principais variáveis determinantes do uso da fisioterapia: educação (OR = 1,24) e capacidade de caminhada (OR = 0,82). A diminuição da capacidade de caminhar e maior nível educacional aumentam o uso da fisioterapia em indivíduos com doença de Parkinson vivendo no Brasil. Conclusões: O presente estudo mostra que indivíduos com DP, residentes de diferentes regiões do Brasil, têm acesso limitado aos serviços de fisioterapia. Além disso, o Sistema Brasileiro de Saúde Pública, bem como os programas locais, precisam atingir pessoas de DP com baixo nível educacional para melhorar seu acesso aos serviços de fisioterapia. Os objetivos devem ser para o desenvolvimento de programas de exercícios físicos para melhorar o desempenho funcional dos pacientes por um período mais longo.

RESUMEN

ABSTRACT This study aims to evaluate the profile and knowledge of physiotherapists and occupational therapists from Minas Gerais about the International Classification of Functioning, Disability and Health (ICF) application in professional practice, trying to understand the reason for the underutilization of this universal instrument in Brazil. Observational and cross-sectional study was conducted using an online questionnaire prepared by specialists. An email was sent to all physiotherapists and occupational therapists enrolled in the Regional Council of the 4th Region. Of 22,121 emails, 1,313 were answered. 53% of the sample had graduate certificate, 65% had between two to ten years of experience, and 62% reported that clinics and patients' houses are the places where they work. 72% of the professionals knew the ICF and 84% correctly answered the meaning of the acronym. However, 71% of professionals are unaware of the fields that make up this classification. The first contact with the ICF happened during graduation to 50% of professionals, and 28% had never had contact with ICF. 74% reported not using it in clinical practice. However, 82% of the participants believed that the use of ICF is viable in clinical practice. Most professionals had graduate certificate, worked in clinics and patients' homes and, although most of them claim to know the ICF, the largest portion of the sample reported they did not use this classification in their professional lives, even though believing the ICF use is feasible. The lack of knowledge about the ICF prevents professionals from complying with the recommendations of the World Health Organization (WHO), the Brazilian National Health Council (CNS) and COFFITO (Brazilian Federal Council of Physical Therapy and Occupational Therapy) on the adoption of this instrument in exchange of information about health and clinical practice.

RESUMO O objetivo deste estudo foi avaliar o perfil e conhecimento dos fisioterapeutas (FT) e terapeutas ocupacionais (TO) de Minas Gerais sobre a Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) e sobre a sua aplicação na prática profissional, na tentativa de se compreender o motivo da subutilização deste instrumento universal, no Brasil. Foi realizado estudo observacional e transversal que utilizou um questionário online elaborado por especialistas. Uma correspondência eletrônica foi enviada a todos os FT e TO inscritos no Conselho Regional da 4a região. Das 22.121 correspondências eletrônicas enviadas, 1.313 foram respondidas. 53% da amostra têm pós-graduação, 65% tinham entre dois a 10 anos de experiência, e 97% relataram que as clínicas e domicílio dos pacientes são os lugares onde trabalham. 72% dos profissionais sabiam o que era a CIF e 84% responderam corretamente o significado da sigla. No entanto, 71% dos profissionais desconhecem os componentes desta classificação. O primeiro contato com a CIF aconteceu durante a graduação para 50% dos profissionais e 28% nunca haviam tido contato com a CIF. 74% relataram não usá-la na prática clínica. Entretanto, 82% dos participantes acreditam que ouso da CIF é viável na prática clínica. Embora a maioria dos profissionais afirme conhecer a CIF e acreditar na viabilidade de sua utilização, fica evidente que o conhecimento dos profissionais sobre este importante instrumento ainda é limitado. O desconhecimento sobre a CIF impede que os profissionais cumpram as recomendações da Organização Mundial da Saúde (OMS), Conselho Nacional de Saúde (CNS) e Coffito sobre a adoção deste instrumento na troca de informações na saúde e na prática clínica.

RESUMEN

This study analyzed the relationship between patient characteristics, factors associated with Parkinson's disease (PD), and physical activity level of individuals affected by the disease. Forty-six volunteers with mild-to-moderate idiopathic PD were assessed using sections II/III of the Unified Parkinson's Disease Rating Scale and their motor functions were classified according to the modified Hoehn and Yahr (HY) scale. Data such as age, disease duration, the Human Activity Profile (HAP), the Fatigue Severity Scale were collected. Lower limb bradykinesia and clinical subtypes of PD were defined. Two models that explained 76% of the variance of the HAP were used. The first comprised age, ability to perform activities of daily living (ADL), and the HY scale; the second comprised age, ability to perform ADL, and lower limb bradykinesia. Possible modifiable factors such as the ability to perform ADL and lower limb bradykinesia were identified as predictors of physical activity level of individuals with PD.

RESUMO Este estudo analisou a relação entre características dos pacientes, fatores associados com a doença de Parkinson (DP) e nível de atividade física de indivíduos afetados pela doença. Quarenta e seis voluntários com DP leve a moderada foram avaliados usando a Escala de Avaliação Unificada da Doença de Parkinson (UPDRS), e classificados de acordo com a Escala de Hoehn e Yahr modificada (HY). Dados como idade, duração da doença, Perfil de Atividade Humana (PAH), Escala da Severidade da Fatiga (FSS) foram coletados. Bradicinesia de membros inferiores e subtipos clínicos foram definidos. Dois modelos que explicaram 76% da variância do PAH foram observados. O primeiro compreende idade, habilidade de realizar Atividades de Vida Diária (AVD) e a escala de HY modificada; e o segundo compreende idade, habilidade de realizar AVD, e bradicinesia. Fatores modificáveis como a habilidade de realizar AVD e bradicinesia foram identificados como preditores do nível de atividade física de indivíduos com DP.
