Physical therapy for the management of global function, fatigue and quality of life in amyotrophic lateral sclerosis: systematic review and meta-analyses.

OBJECTIVES: To critically evaluate the effectiveness of physical therapy interventions in improving global function, quality of life and fatigue in individuals with amyotrophic lateral sclerosis (ALS). DESIGN: Systematic review and meta-analyses. DATA SOURCES: MEDLINE, EMBASE, Cochrane Library (CENTRAL) and Physiotherapy Evidence Database (PEDro) were searched through 31 January 2023. ELIGIBILITY CRITERIA: We included randomised clinical trials (RCTs) that compared physical therapy interventions that act on global function, fatigue and quality of life in individuals with ALS with any other non-physiotherapeutic methods and techniques, placebo or non-intervention. The primary outcome measure was the evaluation of global function. Secondary outcomes were quality of life, fatigue and adverse events. DATA EXTRACTION AND SYNTHESIS: Two independent authors used a researcher-developed extraction form and the Rayyan software to search, screen and code included studies. The risk of bias was assessed using the PEDro scale. Meta-analyses were conducted employing random effects. Outcomes were succinctly presented in Grading of Recommendations, Assessment, Development and Evaluation evidence profiles. RESULTS: Our searches identified 39 415 references. After study selection, three studies were included in the review. Such studies involved 62 participants with a mean age of 54.6 years. In the evaluated trials, 40 were male, while 22 participants were female. Regarding the type of onset of the disease, 58 participants had spinal onset of ALS, and four had bulbar. CONCLUSIONS: Physical therapy intervention may improve the global function of individuals with ALS in the short term; however, clinically, it was inconclusive. In terms of quality of life and fatigue, physical therapy intervention is not more effective than control in the short term. Adverse events are not increased by physical therapy intervention in the short term. Due to significant methodological flaws, small sample sizes, wide CIs and clinical interpretation, our confidence in the effect estimate is limited. PROSPERO REGISTRATION NUMBER: CRD42021251350.

Effects of Dignity Therapy on individuals with amyotrophic lateral sclerosis: Case studies.

OBJECTIVES: To analyze the effects of Dignity Therapy (DT) on the physical, existential, and psychosocial symptoms of individuals with amyotrophic lateral sclerosis (ALS). METHODS: This is a mixed-methods case study research that used the concurrent triangulation strategy to analyze the effects of DT on 3 individuals with ALS. Data collection included 3 instances of administering validated scales to assess multiple physical symptoms, anxiety, depression, spiritual well-being, and the Patient Dignity Inventory (PDI), followed by the implementation of DT and a semi-structured interview. RESULTS: The scale results indicate that DT led to an improvement in the assessment of physical, social, emotional, spiritual, and existential symptoms according to the score results. It is worth noting that the patient with a recent diagnosis showed higher scores for anxiety and depression after DT. Regarding the PDI, the scores indicate improvements in the sense of dignity in all 3 cases, which aligns with the positive verbal reports after the implementation of DT. SIGNIFICANCE OF RESULTS: This study allowed us to analyze the effects of DT on the physical, existential, and psychosocial symptoms of individuals with ALS, suggesting the potential benefits of this approach for this group of patients. Participants reported positive effects regarding pain and fatigue, could reflect on their life trajectories, and regained their value and meaning.

[Parkinson-dementia and amyotrophic lateral sclerosis association (complex of Guam). Diagnostic challenge, Mexican patient]. / Asociación Parkinson-demencia y esclerosis lateral amiotrófica (complejo Guam). Reto diagnóstico, paciente mexicano.

Background: The Amyotrophic Lateral Sclerosis-Parkinsonism-Dementia Complex (ALS-PDC) was first described in the islands of Guam. This pathology presented its peak incidence in the 1950s. Due to the rarity of the association, we report a clinical case with this complex. The objective was to describe the nosological and pathogenic implications of these neurodegenerative disorder, since they are not frequent to find in our population. Clinical case: We present a case of Latinoamerican origin who initially manifested systemic symptoms of more than 6 years of evolution, with subsequent cognitive alterations. Later, patient began with gait disturbances and motor symptoms suggestive of parkinsonism with atypical data and data of motor neurone disease (MND). More studies were carried out and confirmed findings compatible with upper and lower motor neuron involvement. A mutation in the POLG gene was observed, related to mitochondrial depletion syndrome. Conclusion: Despite the knowledge of this association, it is an entity whose clinical diagnosis could be very difficult to achieve. In addition, molecular mechanisms have not been fully identified, the most common genes related to Parkinsonism and ALS have been excluded, and even attempts to locate the locus were made, without achieving accurate results. Unfortunately, being a neurodegenerative disease, the prognosis is fatal, with no disease-modifying treatment.

Introducción: el complejo parkinsonismo-demencia-esclerosis lateral amiotrófica fue descrito por primera vez en las islas de Guam. Esta patología presentó su pico de incidencia en los años 50. Debido a la rareza de la asociación, informamos sobre un caso clínico que la presenta. El objetivo fue describir las implicaciones nosológicas y patogénicas de este trastorno neurodegenerativo, ya que no es frecuente encontrar esta asociación en nuestra población. Caso clínico: presentamos un caso de origen latinoamericano que inicialmente se manifestó con síntomas sistémicos de más de 6 años de evolución, con posteriores alteraciones cognitivas. Después presentó alteraciones de la marcha y síntomas motores sugestivos de parkinsonismo con datos atípicos y datos de enfermedad de motoneurona. Se hicieron estudios de extensión que confirmaron hallazgos compatibles con afectación en motoneurona superior e inferior. Observamos mutación en gen POLG, relacionada con síndrome de depleción mitocondrial. Conclusión: a pesar del conocimiento de esta asociación, es una entidad cuyo diagnóstico clínico puede ser muy difícil de obtener. Además, no se han identificado del todo los mecanismos moleculares, se han excluido los genes más comunes relacionados con parkinsonismos y esclerosis lateral amiotrófica e incluso se intentó localizar el locus, sin lograr resultados certeros. Desafortunadamente al ser una enfermedad neurodegenerativa el pronóstico es fatal, sin que haya tratamiento modificador de la enfermedad.

Differential Diagnosis or Etiology: A Case Report on Amyotrophic Lateral Sclerosis-like Neuropathy Associated with HIV Infection.

BACKGROUND: Retroviruses are described as a risk factor for chronic neuropathy. However, it is still unknown if they can work as amyotrophic lateral sclerosis triggers. Over the years, some cases of this association have been described with heterogenous disclosures. CASE REPRESENTATION: This study aimed to report a case of HIV and ALS-like neuropathy and briefly discuss peculiarities of clinical aspects, such as physiopathology and treatment options. The patient underwent neurological examination associated with blood tests, electromyography, analysis of cerebrospinal fluid, and imaging studies. DISCUSSION: A non-systematic review was performed in major databases regarding the topic. The case presented mixed upper and lower motor neuron signs and was framed as a probable case of ALS following the present criteria. CONCLUSION: After a short follow-up and viral load cleansing, neurological stabilization was achieved.

Noninvasive mechanical ventilation assistance in amyotrophic lateral sclerosis: a systematic review.

BACKGROUND: Respiratory failure is the most common cause of death in patients with amyotrophic lateral sclerosis (ALS), and morbidity is related to poor quality of life (QOL). Non-invasive ventilation (NIV) may be associated with prolonged survival and QOL in patients with ALS. OBJECTIVES: To assess whether NIV is effective and safe for patients with ALS in terms of survival and QOL, alerting the health system. DESIGN AND SETTING: Systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting standards using population, intervention, comparison, and outcome strategies. METHODS: The Cochrane Library, CENTRAL, MEDLINE, LILACS, EMBASE, and CRD databases were searched based on the eligibility criteria for all types of studies on NIV use in patients with ALS published up to January 2022. Data were extracted from the included studies, and the findings were presented using a narrative synthesis. RESULTS: Of the 120 papers identified, only 14 were related to systematic reviews. After thorough reading, only one meta-analysis was considered eligible. In the second stage, 248 studies were included; however, only one systematic review was included. The results demonstrated that NIV provided relief from the symptoms of chronic hypoventilation, increased survival, and improved QOL compared to standard care. These results varied according to clinical phenotype. CONCLUSIONS: NIV in patients with ALS improves the outcome and can delay the indication for tracheostomy, reducing expenditure on hospitalization and occupancy of intensive care unit beds.

Impact of Plant-Derived Compounds on Amyotrophic Lateral Sclerosis.

Amyotrophic lateral sclerosis (ALS) is a fatal illness characterized by progressive motor neuron degeneration. Conventional therapies for ALS are based on treatment of symptoms, and the disease remains incurable. Molecular mechanisms are unclear, but studies have been pointing to involvement of glia, neuroinflammation, oxidative stress, and glutamate excitotoxicity as a key factor. Nowadays, we have few treatments for this disease that only delays death, but also does not stop the neurodegenerative process. These treatments are based on glutamate blockage (riluzole), tyrosine kinase inhibition (masitinib), and antioxidant activity (edaravone). In the past few years, plant-derived compounds have been studied for neurodegenerative disorder therapies based on neuroprotection and glial cell response. In this review, we describe mechanisms of action of natural compounds associated with neuroprotective effects, and the possibilities for new therapeutic strategies in ALS.

Fatigue in amyotrophic lateral sclerosis and correlated factors.

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.

Characterization of the nigroestriatal system in a sample of patients with amyotrophic lateral sclerosis.

BACKGROUND: The coexistence of amyotrophic lateral sclerosis (ALS) with clinical forms of Parkinson disease (PD), although uncommon, is found to a greater degree than one would expect by chance. The pathological mechanisms of ALS and PD are still not fully understood, and the coexistence of these two diseases suggests that they could share mechanisms in common. OBJECTIVE: Here we present a sample of patients with clinically definitive or probable ALS who were evaluated with single-photon emission computed tomography SPECT/TRODAT and compared with non-ALS controls. METHODS: Patients with clinically definite or probable ALS were assessed with the amyotrophic lateral sclerosis functional rating scale (ALSFRS) to define severity and had their demographic data collected. The TRODAT results of patients with ALS were compared with those of patients with a diagnosis of PD with less than 10 years of duration, and with patients with a diagnosis of others movement disorders not associated with neurodegenerative diseases. RESULTS: A total of 75% of patients with ALS had TRODAT results below the levels considered normal; that was also true for 25% of the patients in the control group without neurodegenerative disease, and for 100% of the patients in the PD group. A statistically significant difference was found between patients with ALS and the control group without neurodegenerative disease in the TRODAT values < 0.05. CONCLUSIONS: Our study fits with the neuropathological and functional evidence that demonstrates the existence of nigrostriatal dysfunction in patients with ALS. Further research to better understand the role of these changes in the pathophysiological process of ALS needs to be performed.

ANTECEDENTES: A coexistência da esclerose lateral amiotrófica (ELA) com formas clínicas da doença de Parkinson (DP), embora incomum, é encontrada em um grau maior do que seria esperado ao acaso. Os mecanismos patológicos da ELA e da DP ainda não são totalmente compreendidos e a coexistência dessas duas doenças sugere que elas podem compartilhar mecanismos em comum. OBJETIVO: Apresentamos uma amostra de pacientes com ELA clinicamente definida ou provável que foram avaliados com tomografia computadorizada por emissão de fóton único (SPECT)/TRODAT e comparados com controles sem ELA. MéTODOS: Pacientes com ELA clinicamente definida ou provável foram avaliados com a escala funcional de esclerose lateral amiotrófica (ALSFRS) para definir a gravidade e foram coletados os seus dados demográficos. Os resultados do TRODAT de pacientes com ELA foram comparados com aqueles de pacientes com diagnóstico de DP com menos de 10 anos de duração e com pacientes com diagnóstico de outros distúrbios do movimento não associados a doenças neurodegenerativas. RESULTADOS: Um total de 75% dos pacientes com ELA apresentou resultados de TRODAT abaixo dos níveis considerados normais; 25% no grupo controle sem doença neurodegenerativa e 100% no grupo DP. Uma diferença estatisticamente significativa foi encontrada entre os pacientes com ELA e o grupo controle sem doença neurodegenerativa nos valores de TRODAT p < 0,05. CONCLUSõES: Nosso estudo está de acordo com as evidências neuropatológicas e funcionais que demonstram a existência de disfunção nigroestriatal em pacientes com ELA. Mais pesquisas para entender melhor o papel dessas mudanças no processo fisiopatológico da ELA precisam ser realizadas.

FUS as a cause of familial Amyotrophic lateral sclerosis, a case report in a pregnant patient.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease. In 10% the disease is familial and rarely occurs in childbearing age women. A 28-year-old female pregnancy patient presented a two-month history of dropped head syndrome, dysphagia, muscle weakness, atrophy, and lingual wasting. Electromyography supported the diagnosis of ALS. Due to family history and background, we carried out molecular genetic testing. We identified a novel variant of uncertain significance: c. 1566 G > C (p.Arg522Ser) in exon 15 in FUS gene. Our findings provide the first case of ALS onset during pregnancy with a novel mutation in FUS gene reported in Mexico.

Effects of respiratory physiotherapy in patients with amyotrophic lateral sclerosis: protocol for a systematic review of randomised controlled trials.

INTRODUCTION: Respiratory muscle weakness and ventilatory failure are common complications in patients with amyotrophic lateral sclerosis (ALS) and may lead to death. Respiratory physiotherapy may improve lung function in this population. This study aims to investigate the effects of respiratory physiotherapy on lung function, cough efficacy and functional status of patients with ALS. METHODS AND ANALYSIS: A protocol was published on the International prospective register of systematic reviews (PROSPERO). The research will cover randomised controlled trials, with no language or publication date restriction, available in the following databases: MEDLINE/PubMed, EMBASE, Cochrane Library, Web of Science and Physiotherapy Evidence Database. The research question will be answered using a search strategy adapted for each database. Searches in databases will be conducted from January 2021 to December 2022. Two authors using the Cochrane risk of bias tool for randomised trials V.2 and Grading of Recommendations, Assessment, Development and Evaluations, respectively, will assess risk of bias and quality of evidence independently. According to the results obtained, data will be reported as a meta-analysis or a narrative report. ETHICS AND DISSEMINATION: No previous ethical approval is required for this publication since data used are already published. Results of this review will be disclosed via peer-reviewed publications and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42021251842.

Quality of life, disability, and clinical variables in amyotrophic lateral sclerosis.

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.

Association between dysphagia and tongue strength in patients with amyotrophic lateral sclerosis.

INTRODUCTION: Amyotrophic lateral sclerosis is the most common motor neuron disease in adults despite it being rare. It is a neurodegenerative disease in which dysphagia is a common and debilitating symptom. Dysphagia can be assessed by complementary exams, such as fiberoptic endoscopic evaluation of swallowing and the tongue strength test, as this is one of the main muscles involved in swallowing. OBJECTIVE: To compare the results of tongue strength and endurance measured by the Iowa oral performance instrument with the findings of the fiberoptic endoscopic evaluation of swallowing examination in patients affected by amyotrophic lateral sclerosis. METHODS: Cross-sectional study, carried out in a tertiary hospital specialized in treatment and rehabilitation. Twenty-five patients diagnosed with amyotrophic lateral sclerosis underwent dysphagia questionnaires, fiberoptic endoscopic evaluation of swallowing examination and tongue strength and resistance test with the Iowa oral performance instrument to assess the presence of dysphagia. RESULTS: Forty-eight percent of the sample had dysphagia at the fiberoptic endoscopic evaluation of swallowing and 76% had an altered tongue strength test. Ninety percent of patients with dysphagia had an average tongue pressure lower than 34.2KPa. The tongue strength test showed sensitivity of 91.67% and specificity of 38.46% and accuracy of 64%. There was a statistically significant relationship between tongue strength and dysphagia and between tongue resistance and dysphagia. CONCLUSION: Tongue strength tests, such as the Iowa oral performance instrument, proved to be effective in assessing dysphagia. This result should encourage further research to facilitate the early diagnosis of dysphagia.

Fasciculaciones y calambres: bases fisiológicas y enfrentamiento clínico de un fenómeno complejo / Fasciculations and cramps: physiological bases and clinical approach of a complex phenomenon

Fasciculations and cramps originate in the motor unit, a functional unit that includes the lower motor neuron and their innervated muscle fibres. Both are common complaints in outpatient practice. These symptoms can be secondary to neurological or medical pathology, presenting a broad differential diagnosis and a complex approach. Recent neurophysiological studies have increased the knowledge of their origin mainly in amyotrophic lateral sclerosis. The symptomatic management of fasciculations and cramps depends on their etiology and includes pharmacological and non-pharmacological treatments. This article aims to present an updated review of the most relevant aspects of physiopathology, clinical approach, and differential diagnosis of both phenomena.

Prevalence of Gastrointestinal Symptoms, Severity of Dysphagia, and Their Correlation with Severity of Amyotrophic Lateral Sclerosis in a Mexican Cohort.

OBJECTIVES: Our study aimed to identify the prevalence and severity of gastrointestinal (GI) symptoms and dysphagia in patients with amyotrophic lateral sclerosis (ALS) and to assess whether a correlation exists between these symptoms and the severity of ALS progression. METHODS: The presence and severity of GI symptoms and dysphagia were identified by means of the Gastrointestinal Symptom Rating Scale (GSRS) and the Functional Outcome Swallowing Scale (FOSS). The Revised ALS Functional Rating Scale (ALSFRS-R) was utilized to determine the severity of ALS. Analysis of data was performed with Spearman correlations in semi-qualitative variables of clinical scales. ALSFRS-R scores were divided into 2 categories: those with mild to moderate ALS (≥40-30 points) and patients with moderate to advanced ALS (29-≤20 points). RESULTS: We studied 43 patients with definite ALS. The most frequent GI symptoms were constipation (60.5%), rectal tenesmus (57.5%), hard stools (55.0%), and borborygmus (42.5%). The moderate to advanced ALS stage was correlated with constipation (r = 0.334; p = 0.028), acid regurgitation (r = 0.384; p = 0.013), eructation (r = 0.334; p = 0.032), rectal tenesmus (r = 0.498; p = 0.001), and functional dysphagia (r = 0.656; p = <0.001). CONCLUSIONS: Early detection of these GI symptoms can guide timely therapeutic decisions to avoid weight loss, a predictor for worse prognosis. This study highlights the relevance of the detection of these symptoms in ALS patients who score ≤29 points in the ALSFRS-R scale to establish an appropriate treatment, prevent systemic complications, provide more comfort, and improve quality of life.

Speech intelligibility in people with Amyotrophic Lateral Sclerosis (ALS). / Inteligibilidade de fala em pessoas com Esclerose Lateral Amiotrófica (ELA).

PURPOSE: To evaluate speech intelligibility and dysarthria, correlated to the functional assessment of Amyotrophic Lateral Sclerosis (ALS). METHODS: Quantitative-descriptive study approved by REC under No. CAAE 62912416.4.0000.5404, comprised of 19 individuals with sporadic or familiar ALS. Data were collected using the Dysarthria Protocol and the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-Re). We used visual analogue scale (VAS) to assess speech intelligibility and summary measures; and Spearman's coefficients of correlation for the instruments with significance level of 5%. RESULTS: Speech intelligibility is compromised (41.37±39.73) in varied degrees with positive correlation with the general degree of dysarthria (p=<.0001), and with all the analyzed speech parameters, indicating impact on the speech deterioration of the studied group. There is negative correlation between speech intelligibility and the results of the bulbar sections - speech and deglutition (p=0.0166), arm - activities with the upper limb (p=0.0064) and leg - activities with the lower limb (p=0.0391). Breathing (p=0.0178), phonation (p=0.0334) and resonance (p=0.0053) parameters showed a negative correlation with the item "speech" of the ALSFRS-Re. CONCLUSION: Results show impaired speech intelligibility and dysarthria, and evidence breathing, phonation and resonance as important markers of the disease progression. A thorough and early evaluation of the oral motor production allows for a better management of alterations in ALS.

OBJETIVO: Avaliar a inteligibilidade de fala e disartria, correlacionando com a avaliação funcional da ELA. MÉTODO: Estudo quantitativo-descritivo aprovado pelo CEP, sob nº CAAE 62912416.4.0000.5404, constituído por 19 pessoas com ELA, esporádica ou familiar. Para coleta, aplicou-se o Protocolo de Disartria e Escala de Avaliação Funcional da Esclerose Lateral Amiotrófica (ALSFRS-Re). Para análise, foi utilizada escala visual analógica para inteligibilidade de fala e medidas de resumo e correlação dos instrumentos pelo Coeficiente de Spearman com nível de significância de 5%. RESULTADOS: A inteligibilidade de fala está comprometida (41,37±39,73) em graus variados com correlação positiva com o grau geral de disartria (p=<,0001) e com todos os parâmetros de fala analisados, indicando impacto na deterioração da fala do grupo estudado. Há correlação negativa entre inteligibilidade de fala e resultados das seções bulbar ­ fala e deglutição (p=0,0166), braço ­ atividades com membro superior (p=0,0064) e perna ­ atividades com membro inferior (p=0,0391). Os parâmetros de respiração (p=0,0178), fonação (p=0,0334) e ressonância (p=0,0053) apresentaram correlação negativa com o item "fala" do ALSFRS-Re. CONCLUSÃO: Os achados mostram prejuízo da inteligibilidade de fala e disartria e evidenciam respiração, fonação e ressonância como importantes marcadores da progressão da doença. Uma avaliação criteriosa e precoce da produção motora oral permite melhor gerenciamento das alterações na ELA.

Fiberoptic endoscopic findings of oropharyngeal swallowing of different food consistencies in Amyotrophic Lateral Sclerosis. / Achados videoendoscópicos da deglutição em diferentes consistências de alimento na Esclerose Lateral Amiotrófica.

PURPOSE: This study aimed to compare the fiberoptic endoscopic findings of oropharyngeal swallowing of distinct food consistencies in Amyotrophic Lateral Sclerosis (ALS). METHODS: This was a retrospective clinical study of a convenience sample of 20 individuals (13 males and seven females aged 34 to 78 years old) with a diagnosis of ALS and oropharyngeal dysphagia confirmed by clinical and objective evaluation of swallowing, regardless of the bulbar or skeletal type and of the time of neurological diagnosis. The fiberoptic endoscopic evaluation of swallowing (FEES) of the liquid (N = 18), thickened liquid (N = 19) and pureed samples (N = 20) in a volume of 5 ml were analyzed. Data related to posterior oral spillage, pharyngeal residues, laryngeal penetration and/or aspiration after swallowing the three food consistencies were analyzed statistically by the Friedman ANOVA test. RESULTS: No impairment of laryngeal sensitivity was found in this population. There was no statistically significant difference in posterior oral spillage, penetration and/or aspiration between food consistencies. There was a statistically significant difference only related to pharyngeal residues of the thickened liquid and pureed consistency. CONCLUSION: Among the fiberoptic endoscopic findings of swallowing in ALS, only pharyngeal residues had a higher frequency depending on the consistency of food.

OBJETIVO: Este estudo teve por objetivo comparar os achados videoendoscópicos da deglutição orofaríngea em distintas consistências de alimento na Esclerose Lateral Amiotrófica (ELA). MÉTODO: Estudo clínico retrospectivo com amostra de conveniência. Foram incluídos 20 indivíduos com diagnóstico de ELA e disfagia orofaríngea confirmada por avaliação clínica e objetiva de deglutição, independentemente do tipo, bulbar ou esquelética, e tempo de diagnóstico neurológico, 13 do sexo masculino e sete do sexo feminino, faixa etária variando de 34 a 78 anos, média de 57 anos. Foram analisados os achados da videoendoscopia de deglutição (VED) nas consistências líquida (N=18), líquida espessada (N=19) e pastosa (N=20) no volume de cinco ml. Os achados sobre escape oral posterior, resíduos faríngeos, penetração laríngea e/ou aspiração foram comparados nas três consistências de alimento e a análise estatística utilizou o teste ANOVA de Friedman. RESULTADOS: Não foi encontrada alteração na sensibilidade laríngea nessa população. Não houve diferença estatística significativa entre as consistências de alimento na presença de escape oral posterior, penetração e/ou aspiração. Houve diferença estatística significativa somente com resíduos faríngeos na consistência líquida espessada e pastosa na ELA. CONCLUSÃO: Dentre os achados videoendoscópicos da deglutição na ELA, somente o resíduo faríngeo teve maior frequência na dependência da consistência de alimento.

Pharyngeal residue in neurogenic oropharyngeal dysphagia. / Resíduos faríngeos nas disfagias orofaríngeas neurogênicas.

PURPOSE: To compare pharyngeal residues of different consistencies among groups of individuals with neurogenic oropharyngeal dysphagia. METHODS: In a cross-sectional study, a fiberoptic endoscopic evaluation was performed in 30 swallowing exams of individuals diagnosed with neurological disease and oropharyngeal dysphagia, regardless of the time or stage of the disease. The individuals were divided into three groups according to etiology: group I, 10 post-stroke, 8 male and 2 female, aged 51 to 80 years (average age: 67 years); group II, 10 individuals with amyotrophic lateral sclerosis, 5 male and 5 female, aged 39 to 78 years (average age: 57 years); group III, 10 examinations of individuals with Parkinson's disease, 5 male and 5 female aged 65-88 years (average age: 74 years). The Yale Pharyngeal Residue Severity Rating Scale was applied by two independent raters in a blind manner for the analysis of pharyngeal residues in valleculae and pyriform sinuses based on the first swallowing of 5 mL of pureed and thickened liquid. RESULTS: No statistically significant difference was observed among groups in the degree of pharyngeal residues of puree food or thickened liquid in the valleculae (p = 0.25/p = 0.18) or the pyriform sinuses (p = 1.41/0.49). CONCLUSION: The pharyngeal residue levels of pureed and thickened liquid were similar for the groups studied, with less severe levels being more frequent.

OBJETIVO: Comparar os resíduos faríngeos por consistência de alimento entre indivíduos com disfagia orofaríngea neurogênica. MÉTODO: Estudo clínico transversal. Realizada análise de 30 exames de videoendoscopia de deglutição de indivíduos com diagnóstico de doenças neurológicas e disfagia orofaríngea, independentemente do tempo ou estágio das doenças. Os indivíduos foram divididos em três grupos: o grupo I composto por 10 indivíduos pós-Acidente Vascular Cerebral, 8 homens e 2 mulheres, faixa etária entre 51 e 80 anos (média 67 anos); o grupo II por 10 indivíduos com Esclerose Lateral Amiotrófica, 5 homens e 5 mulheres, faixa etária entre 39 e 78 anos (média 57 anos), e o grupo III por 10 indivíduos com Doença de Parkinson (DP), 5 homens e 5 mulheres, faixa etária entre 65 e 88 anos (média 74 anos). Para análise dos resíduos faríngeos em valéculas e seios piriformes, foi aplicada a Yale Pharyngeal Residue Severity Rating Scale, considerando a primeira deglutição de 5 mL nas consistências pastosa e líquida espessada, por dois juízes independentes e de forma cega. RESULTADOS: Não houve diferença estatística significativa nos resíduos faríngeos, em valéculas (p= 0,25/ p= 0,18) e seios piriformes (p= 1,41/ 0,49), respectivamente nas consistências pastosa e líquida espessada, nas diferentes doenças estudadas. CONCLUSÃO: Os níveis de resíduos faríngeos na consistência pastosa ou líquida espessada na população estudada foram semelhantes e mais frequentes nos níveis menos grave.

Relationship between oral transit time and functional performance in motor neuron disease.

Oral phase swallowing impairment in motor neuron disease (MND) is caused by tongue weakness, fasciculation and atrophy, which may compromise oral transit time and total feeding time. OBJECTIVE To describe and correlate total oral transit time (TOTT) with functional performance in MND using different food consistencies. METHODS The study was conducted on 20 patients with MND, regardless of type or duration of the disease, of whom nine were excluded due to issues on the videofluoroscopic swallowing images. The remaining 11 patients (nine men and two women) ranged from 31 to 87 years of age (mean: 57 years) with scores on the Penetration Aspiration Scale ranging from ≤ 2 to ≤ 4. The Amyotrophic Lateral Sclerosis Functional Rating Scale - revised questionnaire was applied to classify individuals according to global, bulbar and bulbar/respiratory parameters. Videofluoroscopy of swallowing using 5ml of different consistencies was performed and a quantitative temporal analysis of the TOTT was carried out with the aid of specific software. RESULTS There was a wide variation in the TOTT within the same food consistency among MND patients. There was a correlation between the TOTT and overall functional performance for the thickened liquid consistency (r = -0.691) and between the TOTT and bulbar performance for the pureed consistency (r = -0.859). CONCLUSION Total oral transit time in MND varies within the same food consistency and the longer the TOTT, regardless of food consistency, the lower the functional performance in MND.
