Abstract
INTRODUCTION/AIMS Evaluations of pulmonary, cough, and swallow function are frequently performed to assess disease progression in amyotrophic lateral sclerosis (ALS), yet the relationship between these functions remains unknown. We therefore aimed to determine relationships between these measures in individuals with ALS. METHODS One hundred individuals with ALS underwent standardized tests: forced vital capacity (FVC), maximum expiratory/inspiratory pressure (MEP, MIP), voluntary cough peak expiratory flow (PEF), and videofluoroscopic swallow evaluation (VF). Duplicate raters completed independent, blinded ratings using the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) scale. Descriptives, Spearman's Rho correlations, Kruskal-Wallis analyses, and Pearson's chi-squared tests were completed. RESULTS Mean and standard deviation across pulmonary and cough measures were FVC: 74.2% predicted (± 22.6), MEP: 91.6 cmH2O (± 46.4), MIP cmH2O: 61.1 (± 28.9), voluntary PEF: 352.7 L/min (± 141.6). DIGEST grades included: 0 (normal swallowing): 31%, 1 (mild dysphagia): 48%, 2 (moderate dysphagia): 10%, 3 (severe dysphagia): 10%, and 4 (life-threatening dysphagia): 1%. Positive correlations were observed: MEP-MIP: r = .76, MIP-PEF: r = .68, MEP-PEF: r = .61, MIP-FVC: r = .60, PEF-FVC: r = .49, and MEP-FVC: r = .46, p < .0001. MEP (p = .009) and PEF (p = .04) differed across DIGEST safety grades. Post hoc analyses revealed significant between group differences in MEP and PEF across DIGEST safety grades 0 versus 1 and grades 0 versus 3, (p < .05). DISCUSSION In this cohort of individuals with ALS, pulmonary function, and voluntary cough were associated. Expiratory metrics (MEP, PEF) were diminished in individuals with unsafe swallowing, increasing their risk for effectively defending the airway.

Future Directions for Respiratory Muscle Training in Neuromuscular Disorders: A Scoping Review. Respiration 2024; 103:601-621.

Abstract
BACKGROUND Respiratory muscle training (RMT) aims to improve inspiratory and/or expiratory muscle function in neuromuscular disorders (NMDs). A comprehensive overview of the available literature is lacking. This scoping review explores methodological characteristics, (adverse) effects, and adherence of RMT studies in NMDs. Moreover, it identifies limitations and research gaps in the literature and provides future research directions. SUMMARY Eligible studies were identified using MEDLINE, Embase, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials databases. Three reviewers independently selected articles. Inclusion criteria were English language, original research articles on RMT using a device, patients with an NMD, and pulmonary function tests or respiratory muscle strength as outcome measures. We included NMDs with slow, intermediate and fast progression. Exclusion criteria were critically ill patients, weaning from mechanical ventilation, other neurological disorders, and RMT combined with non-respiratory interventions. One reviewer extracted the data on patients' characteristics, methodological characteristics, results of outcome measures, adverse events, and patient adherence. Forty-five studies were identified. We found a large diversity in study designs and training protocols. The effects of RMT on respiratory muscle strength and/or endurance are variable. Patient adherence was high and no serious adverse events were reported. KEY MESSAGES The diversity in studies across the available literature precludes definitive conclusions regarding the effects of RMT on respiratory muscle function and clinically relevant outcomes in NMDs. Therefore, well-powered and -designed studies that focus on clinically relevant outcomes and assess whether RMT can improve or offset deterioration of respiratory muscle weakness in NMDs are needed.

Li Z, Kang H. Efficacy of non-pharmacological interventions for individuals with amyotrophic lateral sclerosis: systematic review and network meta-analysis of randomized control trials. Sci Rep 2024; 14:11365. [PMID: 38762656 PMCID: PMC11102473 DOI: 10.1038/s41598-024-62213-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Accepted: 05/14/2024] [Indexed: 05/20/2024] Open
Abstract
This network meta-analysis (NMA) aimed to compare the efficacy of five non-pharmacological interventions, including exercise intervention (EI), nutritional intervention (NI), respiratory intervention (RI), psychological intervention (PSI), and integrated physical intervention (IPI), on functional status, quality of life, muscle strength, pulmonary function, and safety in patients with amyotrophic lateral sclerosis (ALS). We searched nine databases, PubMed, Cochrane, Embase, Scopus, Web of Science, CNKI, CBM, WFPD, and CSTJ, for randomized controlled trials of ALS patients. The primary outcome was the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) score. Secondary outcomes were the McGill Quality of Life Questionnaire (McGill-QoL), Medical Research Council (MRC)-sum score, Forced Vital Capacity (FVC), and Fatigue Severity Scale (FSS) score. This NMA was conducted using random-effect models to calculate the standard mean difference (SMD) and 95% confidence interval (CI). All types of supplemental interventions had some benefit for patients with ALS. EI had a beneficial effect on the ALSFRS-R score (SMD: 1.01; 95% CI 0.50-1.51), FVC (SMD: 0.78; 95% CI 0.02-1.55), McGill-QoL (SMD: 0.71 95% CI 0.33-1.08), and MRC (SMD: 1.11; 95% CI 0.08-2.14). RI had a beneficial effect on the ALSFRS-R score (SMD: 0.83 95% CI 0.12-1.55). IPI had a beneficial effect on the ALSFRS-R score (SMD: 0.65 95% CI 0.06-1.24). NI had a beneficial effect on the McGill-QoL (SMD: 0.63 95% CI 0.02-1.23). The current study findings support a multimodal intervention strategy with an emphasis on EI for slowing disease progression in patients with ALS.

A meta-analysis of post-exercise outcomes in people with amyotrophic lateral sclerosis. eNeurologicalSci 2023; 31:100452.

Abstract
Objective To systematically evaluate post-exercise outcomes related to function and quality of life in people with ALS. Methods PRISMA guidelines were used for identifying and extracting articles. Levels of evidence and quality of articles were judged based on The Oxford Centre for Evidence-based Medicine Levels of Evidence and the QualSyst. Outcomes were analyzed with Comprehensive Meta-Analysis V2 software, random effects models, and Hedge's G. Effects were examined at 0-4 months, up to 6 months, and > 6 months. Pre-specified sensitivity analyses were performed for 1) controlled trials vs. all studies and 2) ALSFRS-R bulbar, respiratory, and motor subscales. Heterogeneity of pooled outcomes was computed with the I2 statistic. Results 16 studies and seven functional outcomes met inclusion for the meta-analysis. Of the outcomes explored, the ALSFRS-R demonstrated a favorable summary effect size and had acceptable heterogeneity and dispersion. While FIM scores demonstrated a favorable summary effect size, heterogeneity limited interpretations. Other outcomes did not demonstrate a favorable summary effect size and/or could not be reported due to few studies reporting outcomes. Conclusions This study provides inconclusive guidance regarding exercise regimens to maintain function and quality of life in people with ALS due to study limitations (e.g., small sample size, high attrition rate, heterogeneity in methods and participants, etc.). Future research is warranted to determine optimal treatment regimens and dosage parameters in this patient population.

Home-Based Music Therapy to Support Bulbar and Respiratory Functions of Persons with Early and Mid-Stage Amyotrophic Lateral Sclerosis-Protocol and Results from a Feasibility Study. Brain Sci 2022; 12:494. [PMID: 35448025 PMCID: PMC9027911 DOI: 10.3390/brainsci12040494] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 04/01/2022] [Accepted: 04/06/2022] [Indexed: 01/27/2023] Open
Abstract
Respiratory failure, malnutrition, aspiration pneumonia, and dehydration are the precursors to mortality in ALS. Loss of natural communication is considered one of the worst aspects of ALS. This first study to test the feasibility of a music therapy protocol for bulbar and respiratory rehabilitation in ALS employs a mixed-methods case study series design with repeated measures. Newly diagnosed patients meeting the inclusion criteria were invited to participate, until the desired sample size (n = 8) was achieved. The protocol was delivered to participants in their homes twice weekly for six weeks. Individualised exercise sets for independent practice were provided. Feasibility data (recruitment, retention, adherence, tolerability, self-motivation and personal impressions) were collected. Bulbar and respiratory changes were objectively measured. Results. A high recruitment rate (100%), a high retention rate (87.5%) and high mean adherence to treatment (95.4%) provide evidence for the feasibility of the study protocol. The treatment was well tolerated. Mean adherence to the suggested independent exercise routine was 53%. The outcome measurements to evaluate the therapy-induced change in bulbar and respiratory functions were defined. Findings suggest that the protocol is safe to use in early- and mid-stage ALS and that music therapy was beneficial for the participants' bulbar and respiratory functions. Mean trends suggesting that these functions were sustained or improved during the treatment period were observed for most outcome parameters: Maximal Inspiratory Pressure, Maximal Expiratory Pressure, Peak Expiratory Flow, the Center for Neurologic Study-Bulbar Function Scale speech and swallowing subscales, Maximum Phonation Time, Maximum Repetition Rate-Alternating, Maximum Repetition Rate-Sequential, Jitter, Shimmer, NHR, Speaking rate, Speech-pause ratio, Pause frequency, hypernasality level, Time-to-Laryngeal Vestibule Closure, Maximum Pharyngeal Constriction Area, Peak Position of the Hyoid Bone, Total Pharyngeal Residue C24area. Conclusion. The suggested design and protocol are feasible for a larger study, with some modifications, including aerodynamic measure of nasalance, abbreviated voice sampling and psychological screening.

Abstract
Purpose The prevalence of dysphagia in patients with neurodegenerative diseases (ND) is alarmingly high and frequently results in morbidity and accelerated mortality due to subsequent adverse events (e.g., aspiration pneumonia). Swallowing in patients with ND should be continuously monitored due to the progressive disease nature. Access to instrumental swallow evaluations can be challenging, and limited studies have quantified changes in temporal/spatial swallow kinematic measures in patients with ND. High-resolution cervical auscultation (HRCA), a dysphagia screening method, has accurately differentiated between safe and unsafe swallows, identified swallow kinematic events (e.g., laryngeal vestibule closure [LVC]), and classified swallows between healthy adults and patients with ND. This study aimed to (a) compare temporal/spatial swallow kinematic measures between patients with ND and healthy adults and (b) investigate HRCA's ability to annotate swallow kinematic events in patients with ND. We hypothesized there would be significant differences in temporal/spatial swallow measurements between groups and that HRCA would accurately annotate swallow kinematic events in patients with ND. Method Participants underwent videofluoroscopic swallowing studies with concurrent HRCA. We used linear mixed models to compare temporal/spatial swallow measurements (n = 170 ND patient swallows, n = 171 healthy adult swallows) and deep learning machine-learning algorithms to annotate specific temporal and spatial kinematic events in swallows from patients with ND. Results Differences (p < .05) were found between groups for several temporal and spatial swallow kinematic measures. HRCA signal features were used as input to machine-learning algorithms and annotated upper esophageal sphincter (UES) opening, UES closure, LVC, laryngeal vestibule reopening, and hyoid bone displacement with 66.25%, 85%, 68.18%, 70.45%, and 44.6% accuracy, respectively, compared to human judges' measurements. Conclusion This study demonstrates HRCA's potential in characterizing swallow function in patients with ND and other patient populations.

Abstract
Context/Objective: Respiratory disorders are a common cause of rehospitalization, and premature death in individuals with spinal cord injuries (SCI). Respiratory training combined with community exercise programs may be a method to reduce secondary complications in this population.Objective: The present study explores the inclusion of inspiratory muscle training (IMT) in an existing community exercise program.Design: Case series.Setting: Community.Participants: Participants (N = 6) completed the exercise program. Five were male and one was female; four reported incomplete injuries, and two reported complete injuries; four had cervical injuries, and two had thoracic injuries. The average age was 33 years (SD = 18.6) and time since injury was 7 years (SD = 4.0).Interventions: Participants completed an 8-week program, once-per-week for 4 h that included a circuit of resistance training, aerobic exercise, trunk stability, and education. IMT was completed as a home exercise program.Outcome Measures: Transfer test, T-shirt test, four-directional reach, four-directional trunk strength, weekly training diaries, and a subjective interview.Results: Twenty-eight training logs were collected. All measures improved: transfer test (mean = -14.62, SD = 7.00 s), T-shirt test (mean = -7.83, SD = 13.88 s), four-directional reach (mean = 3.75, SD = 8.06 in) and hand-held dynamometer (mean = 6.73, SD = 8.02 kg). Individuals reported a positive impact of the program.Conclusions: This pilot study demonstrated community exercise with IMT use may have positive impact on functional measures for people with SCI who are vulnerable to respiratory compromise. Continued education may increase successful health outcomes.Trial Registration: NCT03743077.

The addition of respiratory muscle strength training to facilitate swallow and pulmonary rehabilitation following massive tissue loss and severe deconditioning: A case series. Aust Crit Care 2021; 35:210-216. [PMID: 33902987 DOI: 10.1016/j.aucc.2021.03.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Revised: 02/23/2021] [Accepted: 03/21/2021] [Indexed: 11/20/2022] Open
Abstract
INTRODUCTION Impaired respiratory and swallow function in patients with intensive care unit-acquired deconditioning, such as associated with massive tissue loss, is not uncommon and can require prolonged rehabilitation. AIM The aim of the study was to examine the effect of combined inspiratory and expiratory respiratory muscle strength training (RMST) on respiratory and swallow function in two critical care patients with marked deconditioning after massive tissue loss. METHODS Case 1 was a 19-year-old male patient with 80% body surface area burns; case 2 was a 45-year-old man with group A streptococcus myositis necessitating quadruple amputation. Both required prolonged intensive care and mechanical ventilation. Both received routine intensive pulmonary and swallow rehabilitation before the trial; however, chronic aspiration and poor secretion clearance remained. At 25 and 26 weeks after initial injury, RMST was performed using EMST150 (expiratory) and Threshold IMT (inspiratory) devices, respectively. At baseline and throughout treatment, data collected included peak expiratory flow (PEF), anthropometry measures, aspiration risk (Penetration-Aspiration Scale [PAS]), pharyngeal clearance (Yale Pharyngeal Residue Scale), secretions (New Zealand Secretion Scale [NZSS]), and functional diet (Functional Oral Intake Scale [FOIS]) via endoscopy. RESULTS/DISCUSSION At baseline, the PEF score of case 1 was 41% (predicted age-height norm) and the PEF score of case 2 was 14%, indicating severe expiratory compromise. Both had extreme energy requirements (3300 kcal/day; 3500 kcal/day). The baseline swallowing scores of case 1 and 2 were as follows: PAS, 8 and 8; Yale, 9 and 10; NZSS, 4 and 7; and FOIS, 1 and 1, respectively, indicating profound dysphagia. At week 3 of 7 of RMST, swallow function improved to allow both to commence oral intake, followed by tracheostomy decannulation. At weeks 10 and 11, full dysphagia resolution was achieved (FOIS = 7; PAS = 1, Yale = 2, NZSS = 0), with PEF at 70% and 48% predicted respectively. Both patients continued RMST, and at discharge from the acute facility, PEF was 84% and 80% predicted respectively. CONCLUSION The addition of RMST assisted swallow and pulmonary rehabilitation in both cases and was clinically viable to deliver. Controlled validation trials are now required.

Abstract
INTRODUCTION Dystussia impacts the ability to protect the airway. Voluntary cough provides a metric of airway defense but differs from the reflexive response to aspiration during swallowing. Therefore, we evaluated relationships between voluntary and reflexive cough among individuals with amyotrophic lateral sclerosis (ALS) and a healthy cohort. METHODS Twenty-eight individuals with ALS and 26 healthy individuals completed voluntary and reflexive cough testing. Descriptive statistics, reliability, and paired t tests were conducted to evaluate differences in cough volume acceleration (CVA) and peak expiratory flow rate (PEFR) in voluntary vs reflexive cough. RESULTS Compared with reflexive cough, voluntary CVA and PEFR were greater in individuals with ALS [t(27) = 4.83, P < .001 and t(27) = 8.69, P < .001] and the healthy cohort [t(21) = 5.91, P < .001 and t(21) = 12.26, P < .001], respectively. DISCUSSION These findings hold important implications for the use and interpretation of voluntary peak cough flow during clinical swallowing evaluations.

Abstract
Expiratory muscle strength training (EMST) exercise programmes aim to improve respiratory function by increasing the force generating capability of expiratory muscles by resistance training. In neuromuscular conditions, in which cough flow generation is often decreased, there is increasing interest in EMST as a therapeutic intervention. We present data showing efficacy of EMST in a patient with adult onset Myotonic Dystrophy Type 1 (DM1). A domiciliary training programme (5 days per week over 32 weeks) resulted in increases in maximum expiratory mouth pressure (from 15 cmH2O to 38 cmH2O) and peak cough flow (300 L/min to 390 L/min). Improvements were also seen in maximum inspiratory mouth pressure (26 cmH2O to 52 cmH2O) and sniff nasal inspiratory pressure (40 cmH2O to 69 cmH2O). No changes were detected in speech or swallowing. This novel study demonstrates that cough flow generation in DM1 may be increased by a programme of expiratory muscle training. A clinical trial of EMST in DM1 is warranted.

Abstract
Purpose Persons with neurodegenerative disease frequently develop comorbid dysphagia as part of their disease process. Current "reactive" approaches to dysphagia management address dysphagia once it manifests clinically and consist of compensatory approaches. The purpose of this article is to propose a paradigm shift in dysphagia management of patients with neurodegenerative disease from a "reactive to proactive" approach by highlighting amyotrophic lateral sclerosis (ALS) and dementia as case examples. Method The authors present several areas of special consideration for speech-language pathologists (SLPs) treating dysphagia in patients with neurodegenerative disease. The drawbacks of historical "reactive" approaches to dysphagia management are described. Concepts of functional reserve for swallowing and homeostenosis are discussed. A "proactive" patient-centered paradigm of care for these patients is proposed with evidence to support its importance. A rationale for use of this approach in patients with ALS and dementia is provided with strategies for implementation. Results When treating dysphagia in patients with neurodegenerative disease, SLPs must balance a variety of factors in their decision making, including disease severity and expected progression, cultural considerations, goals of care, patient empowerment, and caregiver support. Reactive approaches to dysphagia management in these populations are problematic in that they disempower patients by focusing on use of compensatory techniques (e.g., diet modification, postural changes, feeding tube placement). Proactive approaches that employ rehabilitative interventions to increase functional reserve, such as resistance training, may result in improvement or maintenance of swallowing function longer into disease progression. An interdisciplinary team with early SLP involvement is necessary. Conclusions SLPs play a critical role in the management of dysphagia in patients with neurodegenerative disease and should be integrated early in the care of these patients. By focusing on a proactive patient-centered approach, patients with neurodegenerative conditions, such as ALS and dementia, will experience improved quality of life and health outcomes for a longer time.

Abstract
This case study examined the impact of a respiratory strength training program targeting inspiratory and expiratory musculature in an individual with C9orf72 amyotrophic lateral sclerosis (ALS). The individual tolerated 24 months of respiratory training completed at home, 50 repetitions per day, and 5 days per week. Significant increases in maximum inspiratory pressure (from 71 to 134 centimeters of water), maximum expiratory pressure (from 108 to 197 centimeters of water) and peak cough flow (from 331 to 655 Liters per minute) were noted and forced vital capacity remained unchanged. A moderate intensity respiratory strength training program applied early in the disease progression improved function in this C9orf72 ALS individual.
