“…Our research group created a list of symptoms asked for by clinicians to assess patients in clinics with NMD from peerreviewed articles and international guidelines [9,10,[23][24][25][26], reviewing evidence-based literature and guidelines to develop clinical questionnaires [27,28], and talking to respiratory consultants, specialist nurses and physiotherapists active in teaching hospitals with large respiratory centres. Respiratory physicians, physiologists and specialist physiotherapists from the participating centres were then involved in selecting appropriate and most commonly used questions to assess symptoms.…”

Patients with neuromuscular disease (NMD) are at risk of developing sleepdisordered breathing (SDB) following respiratory muscle involvement. We hypothesised that a questionnaire based on clinical symptoms and signs of diaphragm weakness can be used to screen for SDB in such patients.We developed a self-administered multiple choice questionnaire containing five questions (Sleep-Disordered Breathing in Neuromuscular Disease Questionnaire (SiNQ)-5), scoring 0-10 points. 125 patients were enrolled: 32 with respiratory muscle weakness, 35 subjects with normal respiratory muscle strength and 58 patients with obstructive sleep apnoea (OSA). All subjects underwent full polysomnography.NMD patients with involvement of the respiratory muscles scored mean¡SD 6.8¡2.3 out of 10 points, significantly higher than both OSA patients 2.5¡2.3 and normal subjects 1.0¡2.0 (p,0.001). A score of five or more points in the SiNQ-5 had a sensitivity of 86.2%, specificity of 88.5%, positive predictive value of 69.4% and a negative predictive value of 95.5% to identify NMD with combined SDB.A short self-administered questionnaire, the SiNQ-5, based on clinical symptoms can reliably screen for SDB in patients with diaphragm weakness. However, comorbidities, such as heart failure, that have symptoms influenced by posture could alter diagnostic accuracy.

“…After that, they were asked to immediately close the balloon mouth with the fingers, breathe in to the maximum once again, and then breathe out into the balloon. The subjects adopted the upright position in this study because Allen et al 12) reported that the respiratory capacity was greater by 7.5% in the upright position than in the sitting position. The balloon-blowing exercise was performed two times at maximum balloon-blowing over one minute.…”

Abstract.[Purpose] The aim of this study was to clarify the lung capacity when a balloon-blowing exercise was used to increase patients' lung function.[Subjects] The subjects of the study were 30 young smokers. [Methods] Subjects were randomly divided two groups; The experimental group (n=15) performed a balloon-blowing exercise. The control group (n=15) performed no exercise.[Result] The results indicate that VC, ERV, IRV, FVC, FEV1, FEV1/FVC, PEF significantly improved in the experimental group. In contrast, VC, ERV, IRV, FVC, FEV1, FEV1/FVC, PEF did not significantly change in the control group. There were significant differences in VC, ERV, IRV, FVC, and FEV1 between the experimental group and the control group after the performance of the balloonblowing exercise.[Conclusion] These findings suggest that the balloon-blowing exercise has positive effects on lung function.

“…In patients with ALS, repeated measurement of the CV has been shown to be a simple and efficient way to detect the loss of lung function 8 . With substantial diaphragm weakness, the VC is reduced and falls further when the patient is supine; in normal subjects, the supine fall is < 10% of the sitting values 9 . In longstanding conditions, VC in the supine position decreases between 30-50% compared with upright value 10 .…”

SHORT OVERVIEW OF ALSAmyotrophic lateral sclerosis (ALS) is characterized by progressive degeneration of both cortical and alpha motor neurons of the final common pathway. Despite being a progressive degenerative process which primarily affects motor systems, ALS is now recognized to involve several non-motor systems and in long survivors affects many subcortical structures. Many hypotheses have been formulated about what causes ALS, including chemical exposures, occupational exposure, military service, infectious agents, nutritional intake, physical activity, and trauma. Worldwide, ALS affects white males aged > 60 years more often than any other group 1 . In the past three decades new practice parameters to the clinical care in ALS were developed and several clinical trials were performed². As ALS remains as an incurable, progressive and fatal condition, the treatment strategies are focused in improving the quality of life 3 . The only effective pharmacological treatment is Riluzole, a putative glutamate release blocker linked to modestly prolonged survival 2 . Other therapeutic measures concerning respiratory support are outlined in this paper. PULMONARY FUNCTION IN ALS Respiratory muscle strengthProgressive weakness remains the foremost characteristic of ALS. However, while some ALS patients progress rapidly, others have slow progression of muscle weakness; ABSTRACTAmyotrophic lateral sclerosis is a progressive neuromuscular disease, resulting in respiratory muscle weakness, reduced pulmonary volumes, ineffective cough, secretion retention, and respiratory failure. Measures as vital capacity, maximal inspiratory and expiratory pressures, sniff nasal inspiratory pressure, cough peak flow and pulse oximetry are recommended to monitor the respiratory function. The patients should be followed up by a multidisciplinary team, focused in improving the quality of life and deal with the respiratory symptoms. The respiratory care approach includes airway clearance techniques, mechanically assisted cough and noninvasive mechanical ventilation. Vaccination and respiratory pharmacological support are also recommended. To date, there is no enough evidence supporting the inspiratory muscle training and diaphragmatic pacing.Keywords: amyotrophic lateral sclerosis, respiratory function, rehabilitation. RESUMOEsclerose lateral amiotrófica é uma doença neuromuscular progressiva que resulta em fraqueza muscular, redução dos volumes pulmonares, tosse ineficaz, retenção de secreção e insuficiência respiratória. Medidas como a capacidade vital, pressão inspiratória e pressão expiratória máximas, pressão inspiratória máxima nasal, pico de fluxo de tosse e oximetria de pulso são recomendados para monitorar a função respiratória. Os pacientes devem ser acompanhados por uma equipe multidisciplinar, buscando melhorias na qualidade de vida e melhores estratégias para lidar com os sintomas respiratórios. A abordagem de cuidados respiratórios inclui técnicas de desobstrução das vias respiratórias, tosse assistida mecanicamente e ventilaç...
