ABSTRACT

BACKGROUND: Sleep disorders have a prevalence of 30% to 70% in post-stroke individuals. The presence of sleep disorders and poor sleep quality after stroke can affect important functions and lead to worse outcomes. However, most studies are restricted to the acute post-stroke stage only. OBJECTIVE: To investigate the frequency of self-reported sleep alterations in a sample of chronic stroke individuals and to identify which self-reported sleep alterations were associated with disability. METHODS: Prospective exploratory study. Self-reported sleep alterations were measured by the Pittsburgh Sleep Quality Index, Insomnia Severity Index, Epworth Sleepiness Scale, and STOP-Bang Questionnaire. The dependent variable was measured 3 years after the first contact by the Modified Rankin Scale (mRS). Step-wise multiple linear regression analysis was employed to identify which sleep alterations were associated with disability. RESULTS: Sixty-five individuals with stroke participated. About 67.7% of participants had poor sleep quality, 52.4% reported insomnia symptoms, 33.9% reported excessive daytime sleepiness, and 80.0% were classified as intermediate or high risk for obstructive sleep apnea. Only risk for obstructive sleep apnea was significantly associated with disability and explained 5% of the variance in the mRS scores. CONCLUSION: Self-reported sleep alterations had a considerable frequency in a sample of chronic stroke individuals. The risk of obstructive sleep apnea was associated with disability in the chronic stage of stroke. Sleep alterations must be considered and evaluated in the rehabilitation process even after a long period since the stroke onset.

ABSTRACT

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that leads to muscle weakness and paralysis. Fatigue is a disabling symptom, frequently reported in ALS, but remains under-investigated in this population. Thus, an accurate investigation of this symptom and possible associated factors in this clinical condition is needed to assist in the establishment of an adequate treatment approach. OBJECTIVE: To investigate the presence of fatigue in individuals with ALS and possible factors correlated with this symptom. METHODS: Sixty-five individuals with sporadic ALS participated in the present study. Demographic, clinical, and functional aspects were investigated. Evaluations involved the Fatigue Severity Scale (FSS), ALS Functional Scale (ALSRFS-R), and Quality of Life (QoL) questionnaire (ALSAQ-40). Descriptive and correlation analyses were performed with SPSS statistical program for Windows version 19.0 (IBM Corp., Armonk, NY, USA). RESULTS: Among the 65 individuals evaluated, 44.6% (n = 29) presented fatigue based on the FSS. The mean fatigue intensity was 5.4 ± 1.2 and only 10.4% used a specific medication for fatigue. Differences between the groups with and without fatigue were found regarding sex (p = 0.049), pain intensity (p = 0.026), functioning (p = 0.004), disease severity (p = 0.029), and QoL (p = 0.000). Fatigue was correlated with pain intensity (r = 0.425; p = 0.001), muscle strength (r = - 0.356; p = 0.004), functioning (r = - 0.363; p = 0.003), and QoL (r = 0.481; p = 0.000). No correlations were found with age, time since diagnosis, cramps, or other mobility parameters. CONCLUSIONS: Fatigue is a common symptom among individuals with ALS and may be present in all stages of the disease. This symptom was correlated with worse functioning, poorer QoL, greater pain intensity, disease severity, muscle weakness, and the female sex in individuals with ALS.


ANTECEDENTES: Esclerose lateral amiotrófica (ELA) é uma doença neurodegenerativa fatal que leva à fraqueza muscular e paralisia. Fadiga é um sintoma incapacitante, frequentemente relatado na ELA, mas permanece pouco investigado nessa população. Assim, uma investigação acurada deste sintoma e dos possíveis fatores associados é necessária para auxiliar em uma abordagem terapêutica adequada. OBJETIVO: Investigar a presença de fadiga em indivíduos com ELA e possíveis fatores correlacionados a este sintoma. MéTODOS: Participaram 65 indivíduos com ELA esporádica. Aspectos demográficos, clínicos e funcionais foram investigados. Foram utilizadas: Escala de Severidade de Fadiga (FSS, na sigla em inglês), Escala Funcional de ELA (ALSRFS-R, na sigla em inglês) e questionário de Qualidade de Vida (QV) (ALSAQ-40, na sigla em inglês). Análises descritivas e de correlação foram realizadas no programa SPSS para Windows versão 19.0 (IBM Corp., Armonk, NY, USA). RESULTADOS: Dos 65 indivíduos avaliados, 44,6% (n = 29) apresentaram fadiga pela FSS. A intensidade da fadiga foi 5,4 ± 1,2 e apenas 10,4% usavam medicamento específico para fadiga. Diferenças entre os grupos com e sem fadiga foram encontradas em relação ao sexo (p = 0,049), intensidade da dor (p = 0,026), funcionalidade (p = 0,004), gravidade da doença (p = 0,029) e QV (p = 0,000). A fadiga foi correlacionada com a intensidade da dor (r = 0,425; p = 0,001), força muscular (r = - 0,356; p = 0,004), funcionalidade (r = - 0,363; p = 0,003) e QV (r = 0,481; p = 0,000). Não foram encontradas correlações com idade, tempo de diagnóstico, cãibras ou outros parâmetros de mobilidade. CONCLUSõES: A fadiga é um sintoma comum entre os indivíduos com ELA e pode estar presente em todos os estágios da doença. Este sintoma estava correlacionado à pior funcionalidade, pior QV, gravidade, intensidade da dor, fraqueza muscular e sexo feminino em indivíduos com ELA.

ABSTRACT

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a motor neuron disease that results in a progressive increase in dysfunctions, limitations and restrictions over time, which can impact on quality of life (QoL). Therefore, expanding knowledge on QoL and possible factors associated with ALS can enable the development of actions to ensure greater wellbeing for the population. OBJECTIVE: To investigate QoL in ALS and determine associations with demographic, functional and clinical aspects. METHODS: Forty-five individuals with ALS (56.4±11.1 years) participated in the study. Demographic, clinical and functional aspects were investigated. Functioning and QoL were assessed using disease-specific tools (ALS Functional Ranting Scale-Revised/ALSFRS-R and ALS Assessment Questionnaire/ALSAQ-40). Fatigue was assessed using the Fatigue Severity Scale. Descriptive, correlation and stepwise multiple linear regression analyses were performed with the aid of the SPSS. RESULTS: The mean ALSAQ-40 score was 279.0±118.3. QoL was significantly worse among women (p=0.001) and poor QoL was associated with the inability to walk (p=0.014), pain (p=0.021) and disease severity (p≤0.002). QoL was strongly correlated with the ALSFRS-R score (r=-0.82). Moderate to weak correlations were found for mobility [turning in bed (r=-0.62), locomotion (r=-0.33) and sit to stand (r=-0.40)], strength (r=-0.49), fatigue (r=0.35) and pain (r=-0.32) (p<0.03). The regression analysis revealed that the ALSFRS-R score (ß=-0.76; p=0.00) and fatigue (ß=0.20; p=0.04) were predictors of QoL. CONCLUSIONS: QoL was worse in women, older people, severe stages of ALS, patients with impaired mobility, those with a poorer physical performance and those who reported pain. Functional status and fatigue are predictors of QoL in ALS.

ABSTRACT

Abstract Introduction: Amyotrophic lateral sclerosis (ALS) is a disabling neurodegenerative disease, which compromises locomotion and functional independence. As the goal of physical therapy is to maintain the individual's locomotion capacity and independence as long as possible, it is necessary to gain a better understanding of the possible factors associated with the loss of this capacity. Objective: To evaluate functional ambulation in patients with ALS and possible factors associated with its decline. Methods: A cross-sectional study was conducted with sporadic ALS patients. Demographic and clinical/functional aspects were evaluated. ALS Functional Rating Scale-Revised (ALSFRS-R), Functional Ambulation Category, Medical Research Council scale and Fatigue Severity Scale were used. Descriptive and comparative analyses were conducted of the groups capable and incapable of functional ambulation. Binary logistic regression (stepwise forward method) was performed to determine potential factors associated with the loss of functional ambulation. Results: Among the 55 patients (mean age: 56.9 ± 11.2 years), 74.5% were able to walk functionally. Differences were found between groups regarding time of diagnosis, number of falls, pain, use of noninvasive ventilation, gastrostomy, ability to turn in bed, mobility aids, home adaptations, functional performance, muscle strength and fatigue. The possible predictors of walking disability were overall muscle strength (OR = 0.837; p = 0.003) and fatigue (OR =1.653; p = 0.034). Conclusion: Muscle strength and fatigue are associated with the decline in ambulation capacity in patients with ALS. In view of the complexity of elements involved in walking, further studies are needed to investigate the influence of these aspects in this population.


Resumo Introdução: A esclerose lateral amiotrófica (ELA) é uma doença neurodegenerativa incapacitante, que compromete a locomoção e a independência funcional. Como o objetivo da fisioterapia é manter a capacidade de locomoção e independência do indivíduo pelo maior tempo possível, é necessário conhecer melhor os possíveis fatores associados à perda dessa capacidade. Objetivo: Avaliar a deambulação funcional em pacientes com ELA e possíveis fatores associados ao seu declínio. Métodos: Realizou-se um estudo transversal com ELA esporádica. Aspectos demográficos e clínicos/funcionais foram avaliados. A Escala Funcional de ELA (ALSFRS-R), a Escala de Categoria de Deambulação Funcional (FAC), a Medical Research Council Scale e a Escala de Severidade de Fadiga (FSS) foram usadas. Foram realizadas análises descritivas e comparativas dos grupos capazes e incapazes de deambulação funcional. A regressão logística binária (método stepwise forward) foi realizada para determinar os potenciais fatores associados à perda da deambulação funcional. Resultados: Entre os 55 pacientes (média de idade: 56,9 ± 11,2 anos), 74,5% eram capazes de deambular funcionalmente. Encontraram-se diferenças entre os grupos quanto ao tempo de diagnóstico, número de quedas, dor, uso de ventilação não invasiva, gastrostomia, capacidade de se virar no leito, auxiliares de locomoção, adaptações domiciliares, desempenho funcional, força muscular e fadiga. Os possíveis preditores de incapacidade de locomoção foram força muscular geral (OR = 0,837; p = 0,003) e fadiga (OR = 1,653; p = 0,034). Conclusão: A força muscular e a fadiga estão associadas ao declínio da capacidade de deambulação em pacientes com ELA. Diante da complexidade dos elementos envolvidos na caminhada, são necessários mais estudos que investiguem a influência desses aspectos nessa população.

ABSTRACT

Objective: To investigate the sleep state and determine whether variables, such as age, functional status, walking capacity, fatigue, depressive symptoms, and quality of life were associated with sleep quality of individuals with chronic stroke.Methods: For this exploratory study, the dependent variable was sleep quality, which was measured by the Pittsburgh Sleep Quality Index (PSQI). Step-wise multiple linear regression analysis was employed to identify which of the independent variables, that is, age, functional status (Modified Rankin Scale-mRS), walking capacity (6-minute Walk Test), fatigue (Fatigue Severity Scale), depressive symptoms (Geriatric Depression Scale-GDS), and quality of life (EuroQol) were associated with sleep quality.Results: Ninety participants, 55 (61%) men, who had a mean age of 61 (SD 12) years and a mean time since the onset of the stroke of 58.2 (SD 58.7) months, were included. Sleep quality was significantly associated with depressive symptoms and functional status. Together, they explained 30% of the variance in the PSQI scores (p < .0001). The GDS scores alone explained 22% (F = 25.76; p < .0001) of the variance in sleep quality (PSQI). When mRS scores were included in the model, the explained variance increased to 30% (F = 20,38; p < .0001).Conclusion: Depressive symptoms and functional status, which are both potentially modifiable factors, were associated with the sleep quality of individuals with chronic stroke. It is important to consider the assessment of sleep quality in the context of stroke rehabilitation.
